WASHINGTON (Reuters) – Governments turned their attention to a possible new wave of cyber threats on Tuesday after the group that leaked U.S. hacking tools used to launch the global WannaCry “ransomware” attack warned it would release more malicious code.

The fast-spreading cyber extortion campaign, which has infected more than 300,000 computers worldwide since Friday, eased for second day on Tuesday, but the identity and motive of its creators remain unknown.

The attack includes elements that belong to the U.S. National Security Agency and were leaked online last month.

Shadow Brokers, the group that has taken credit for that leak, threatened on Tuesday to release more recent code to enable hackers to break into the world’s most widely used computers, software and phones.

A blog post written by the group promised from June to release tools every month to anyone willing to pay for access to some of the tech world’s biggest commercial secrets.

It also threatened to dump data from banks using the SWIFT international money transfer network and from Russian, Chinese, Iranian or North Korean nuclear and missile programs. “More details in June,” it promised.

The spread of the WannaCry attack – which encrypts a user’s data and demands a “ransom” be paid electronically to free it up again – slowed to a trickle on Tuesday, with few, isolated examples being reported.

In Canada, the Universite de Montreal was hit, with 120 of the French-language university’s 8,300 computers affected, according to a university spokeswoman.

There were no new, major incidents in the United States. Fewer than 10 U.S. organizations have reported attacks to the Department of Homeland Security since Friday, a U.S. official told reporters on Tuesday.

The attack has caused most damage in Russia, Taiwan, Ukraine and India, according to Czech security firm Avast.

The United States likely avoided greater harm as the attack targeted older versions of Microsoft Corp’s <MSFT.O> Windows operating system, and more U.S. users have licensed, up-to-date, patched versions of the software, compared to other regions of the world.

The Department of Homeland Security began an “aggressive awareness campaign” to alert the tech industry to the importance of installing the patch that Microsoft issued in March that protected users from the vulnerability exploited by the attack, a U.S. official working on the attack told Reuters.

Microsoft said on Tuesday it was aware of Shadow Brokers’ most recent claim and that its security teams monitor potential threats in order to “help us prioritize and take appropriate action.”

Microsoft President and Chief Legal Officer Brad Smith said earlier this week the WannaCry attack used elements stolen from the NSA. The U.S. government has not commented directly on the matter.

NORTH KOREA LINK PROBED

Cyber security researchers around the world have said they have found evidence that could link North Korea with the WannaCry cyber attack.

A researcher from South Korea’s Hauri Labs said on Tuesday their own findings matched those of Symantec <SYMC.O> and Kaspersky Lab, who said on Monday that some code in an earlier version of the WannaCry software had also appeared in programs used by the Lazarus Group, identified by some researchers as a North Korea-run hacking operation.

“It is similar to North Korea’s backdoor malicious codes,” said Simon Choi, a senior researcher with Hauri who has done extensive research into North Korea’s hacking capabilities and advises South Korean police and National Intelligence Service.

Both Symantec and Kaspersky said it was too early to tell whether North Korea was involved in the attacks, based on the evidence that was published on Twitter by Google security researcher Neel Mehta.

FireEye Inc <FEYE.O>, another large cyber security firm, said it was also investigating, but it was cautious about drawing a link to North Korea.

“The similarities we see between malware linked to that group and WannaCry are not unique enough to be strongly suggestive of a common operator,” FireEye researcher John Miller said.

U.S. and European security officials told Reuters on condition of anonymity that it was too early to say who might be behind the attacks, but they did not rule out North Korea as a suspect.

The Lazarus hackers, acting for impoverished North Korea, have been more brazen in their pursuit of financial gain than others, and have been blamed for the theft of $81 million from the Bangladesh central bank, according to some cyber security firms. The United States accused it of being behind a cyber attack on Sony Pictures in 2014.

North Korea has denied being behind the Sony and banking attacks. North Korean officials were not immediately available for comment and its state media has been quiet about the matter.

NO INFORMATION TO SHARE

In China, foreign ministry spokeswoman Hua Chunying said she had no information to share, when asked about the origin of the attack and whether North Korea might be connected.

Several Asian countries have been affected by the malware, although the impact has not been as widespread as some had feared.

In Malaysia, cyber security firm LE Global Services said it identified 12 cases so far, including a large government-linked corporation, a government-linked investment firm and an insurance company. It did not name any of the entities.

“We may not see the real picture yet, as companies are not mandated to disclose security breaches to authorities in Malaysia,” said LE Global CEO Fong Choong Fook.

“The real situation may be serious. In one of the cases, the attack was traced back to early April.”

Vietnam’s state media said on Tuesday more than 200 computers had been affected, but one of the country’s leading anti virus companies, Bkav, later put the figure at 1,900.

Taiwan Power Co. <TAIWP.UL> said that nearly 800 of its computers were affected, although these were used for administration, not for systems involved in electricity generation.

Chinese state media says U.S. should take some blame for cyber attack

BEIJING (Reuters) – Chinese state media on Wednesday criticized the United States for hindering efforts to stop global cyber threats in the wake of the WannaCry “ransomware” attack that has infected more than 300,000 computers worldwide in recent days.

The U.S. National Security Agency (NSA) should shoulder some blame for the attack, which targets vulnerabilities in Microsoft Corp <MSFT.O> systems and has infected some 30,000 Chinese organizations as of Saturday, the China Daily said.

“Concerted efforts to tackle cyber crimes have been hindered by the actions of the United States,” it said, adding that Washington had “no credible evidence” to support bans on Chinese tech firms in the United States following the attack.

The malware attack, which began on Friday and has been linked by some researchers to previous hits by a North Korean-run hacking operation, leveraged a tool built by the NSA that leaked online in April, Microsoft says.

It comes as China prepares to enforce a wide-reaching cyber security law that U.S. business groups say will threaten the operations of foreign firms in China with strict local data storage laws and stringent surveillance requirements.

China’s cyber authorities have repeatedly pushed for what they call a more “equitable” balance in global cyber governance, criticizing U.S. dominance.

The China Daily pointed to the U.S. ban on Chinese telecommunication provider Huawei Technologies Co Ltd [HWT.UL], saying the curbs were hypocritical given the NSA leak.

Beijing has previously said the proliferation of fake news on U.S. social media sites, which are largely banned in China, is a reason to tighten global cyber governance.

The newspaper said that the role of the U.S. security apparatus in the attack should “instill greater urgency” in China’s mission to replace foreign technology with its own.

The state-run People’s Daily compared the cyber attack to the terrorist hacking depicted in the U.S. film “Die Hard 4”, warning that China’s role in global trade and internet connectivity opened it to increased risks from overseas.

The fast-spreading cyber extortion campaign eased for second day on Tuesday, but the identity and motive of its creators remain unknown.

SEOUL/WASHINGTON (Reuters) – Cybersecurity researchers have found evidence they say could link North Korea with the WannaCry cyber attack that has infected more than 300,000 computers worldwide, as global authorities scrambled to prevent hackers from spreading new versions of the virus.

A researcher from South Korea’s Hauri Labs said on Tuesday their own findings matched those of Symantec <SYMC.O> and Kaspersky Lab, who said on Monday that some code in an earlier version of the WannaCry software had also appeared in programs used by the Lazarus Group, identified by some researchers as a North Korea-run hacking operation.

“It is similar to North Korea’s backdoor malicious codes,” said Simon Choi, a senior researcher with Hauri who has done extensive research into North Korea’s hacking capabilities and advises South Korean police and National Intelligence Service.

Both Symantec and Kaspersky said it was too early to tell whether North Korea was involved in the attacks, based on the evidence that was published on Twitter by Google security researcher Neel Mehta.

The attacks, which slowed on Monday, are among the fastest-spreading extortion campaigns on record.

In China, foreign ministry spokeswoman Hua Chunying said she had no information to share, when asked about the origin of the attack and whether North Korea might be connected.

Several Asian countries have been affected by the malware, although the impact has not been as widespread as some had feared.

In Malaysia, cybersecurity firm LE Global Services said it identified 12 cases so far, including a large government-linked corporation, a government-linked investment firm and an insurance company. It did not name any of the entities.

“We may not see the real picture yet, as companies are not mandated to disclose security breaches to authorities in Malaysia,” said LE Global CEO Fong Choong Fook.

Vietnam’s state media said on Tuesday more than 200 computers had been affected.

Taiwan Power Co. <TAIWP.UL> said that nearly 800 of its computers were affected, although these were used for administration, not for systems involved in electricity generation.

EXPERTS URGE CAUTION

FireEye Inc <FEYE.O>, another large cyber security firm, said it was also investigating, but it was cautious about drawing a link to North Korea.

“The similarities we see between malware linked to that group and WannaCry are not unique enough to be strongly suggestive of a common operator,” FireEye researcher John Miller said.

The United States accused it of being behind a cyber attack on Sony Pictures in 2014.

An official at South Korea’s Korea Internet & Security Agency said on Tuesday the agency was sharing information with intelligence officials on recent cases reported for damages but was not in position to investigate the source of the attack.

The official declined to comment on intelligence-related matters.

A South Korean police official that handles investigations into hacking and cyber breaches said he was aware of reports on the North Korean link, but said police were not investigating yet.

Victims haven’t requested investigations but they want their systems to be restored, the official said.

North Korea has denied being behind the Sony and banking attacks. North Korean officials were not immediately available for comment and its state media has been quiet about the matter.

Hauri researcher Choi said the code bore similarities with those allegedly used by North Korean hackers in the Sony and bank heists. He said based on his conversations with North Korean hackers, the reclusive state had been developing and testing ransomware programs since August.

In one case, alleged hackers from North Korea demanded bitcoin in exchange for client information they had stolen from a South Korean shopping mall, Choi added.

The North Korean mission to the United Nations was not immediately available for comment on Monday.

While the attacks have raised concerns for cyber authorities and end-users worldwide, they have helped cybersecurity stocks as investors bet governments and corporations will spend more to upgrade their defenses.

Cisco Systems <CSCO.O> closed up 2.3 percent on Monday and was the second-biggest gainer in the Dow Jones Industrial Average.

Oddities in WannaCry ransomware puzzle cybersecurity researchers

By Jeremy Wagstaff

SINGAPORE (Reuters) – The WannaCry malware that spread to more than 100 countries in a few hours is throwing up several surprises for cybersecurity researchers, including how it gained its initial foothold, how it spread so fast and why the hackers are not making much money from it.

Some researchers have found evidence they say could link North Korea with the attack, but others are more cautious, saying that the first step is shedding light on even the most basic questions about the malware itself.

For one thing, said IBM Security’s Caleb Barlow, researchers are still unsure exactly how the malware spread in the first place. Most cybersecurity companies have blamed phishing e-mails – e-mails containing malicious attachments or links to files – that download the ransomware.

That’s how most ransomware finds its way onto victims’ computers.

The problem in the WannaCry case is that despite digging through the company’s database of more than 1 billion e-mails dating back to March 1, Barlow’s team could find none linked to the attack.

“Once one victim inside a network is infected it propagates,” Boston-based Barlow said in a phone interview, describing a vulnerability in Microsoft Windows that allows the worm to move from one computer to another.

The NSA used the Microsoft flaw to build a hacking tool codenamed EternalBlue that ended up in the hands of a mysterious group called the Shadow Brokers, which then published that and other such tools online.

But the puzzle is how the first person in each network was infected with the worm. “It’s statistically very unusual that we’d scan and find no indicators,” Barlow said.

Other researchers agree. “Right now there is no clear indication of the first compromise for WannaCry,” said Budiman Tsjin of RSA Security, a part of Dell.

Knowing how malware infects and spreads is key to being able to stop existing attacks and anticipate new ones. “How the hell did this get on there, and could this be repeatedly used again?” said Barlow.

PALTRY RANSOM

Some cybersecurity companies, however, say they’ve found a few samples of the phishing e-mails. FireEye said it was aware customers had used its reports to successfully identify some associated with the attack.

But the company agrees that the malware relied less on phishing e-mails than other attacks. Once a certain number of infections was established, it was able to use the Microsoft vulnerability to propagate without their help.

There are other surprises, that suggest this is not an ordinary ransomware attack.

Only paltry sums were collected by the hackers, according to available evidence, mostly in the bitcoin cryptocurrency.

There were only three bitcoin wallets and the campaign has far earned only $50,000 or so, despite the widespread infections. Barlow said that single payments in some other ransomware cases were more than that, depending on the victim.

Jonathan Levin of Chainalysis, which monitors bitcoin payments, said there were other differences compared to most ransomware campaigns: for instance the lack of sophisticated methods used in previous cases to convince victims to pay up. In the past, this has included hot lines in various languages.

And so far, Levin said, the bitcoin that had been paid into the attackers’ wallets remained there – compared to another campaign, known as Locky, which made $15 million while regularly emptying the bitcoin wallets.

“They really aren’t set up well to handle their bitcoin payments,” Levin said.

The lack of sophistication may bolster those cybersecurity researchers who say they have found evidence that could link North Korea to the attack.

A senior researcher from South Korea’s Hauri Labs, Simon Choi, said on Tuesday the reclusive state had been developing and testing ransomware programs only since August. In one case, the hackers demanded bitcoin in exchange for client information they had stolen from a South Korean shopping mall.

Choi, who has done extensive research into North Korea’s hacking capabilities, said his findings matched those of Symantec and Kaspersky Lab, who say some code in an earlier version of the WannaCry software had also appeared in programs used by the Lazarus Group, identified by some researchers as a North Korea-run hacking operation.

The Lazarus hackers have however been more brazen in their pursuit of financial gain than others, and have been blamed for the theft of $81 million from the Bangladesh central bank, according to some cybersecurity firms. The United States accused it of being behind a cyber attack on Sony Pictures in 2014.

Whoever is found to be behind the attack, said Marin Ivezic, a cybersecurity partner at PwC in Hong Kong, the way the hackers used freely available tools so effectively may be what makes this campaign more worrying.

By bundling a tool farmed from the leaked NSA files with their own ransomware, “they achieved better distribution than anything they could have achieved in a traditional way” he said.

“EternalBlue (the hacking tool) has now demonstrated the ROI (return on investment) of the right sort of worm and this will become the focus of research for cybercriminals,” Ivezic said.

Global cyber attack slows but experts see risk of fresh strikes

By Jeremy Wagstaff and Eric Auchard

SINGAPORE/FRANKFURT (Reuters) – A global cyber attack described as unprecedented in scale forced a major European automaker to halt some production lines while hitting schools in China and hospitals in Indonesia on Saturday, though it appeared to die down a day after its launch.

Capitalizing on spying tools believed to have been developed by the U.S. National Security Agency, the cyber assault has infected tens of thousands of computers in nearly 100 countries, with Britain’s health system suffering the worst disruptions.

Cyber extortionists tricked victims into opening malicious malware attachments to spam emails that seemed to contain invoices, job offers, security warnings and other legitimate files.

Once inside the targeted network, so-called ransomware made use of recently revealed spy tools to silently infect other out-of-date machines without any human intervention. This, security experts said, marked an unprecedented escalation in the risk of fresh attacks spreading in the coming days and weeks.

The ransomware encrypted data on the computers, demanding payments of $300 to $600 to restore access. Researchers observed some victims paying via the digital currency bitcoin, though no one knows how much may have been transferred to extortionists because of the largely anonymous nature of such transactions.

Researchers with security software maker Avast said they had observed 126,534 ransomware infections in 99 countries, with Russia, Ukraine and Taiwan the top targets.

The hackers, who have not come forward to claim responsibility or otherwise been identified, took advantage of a worm, or self-spreading malware, by exploiting a piece of NSA spy code known as “Eternal Blue” that was released last month by a hackers group known as the Shadow Brokers, according to researchers with several private cyber security firms.

Renault said it had halted auto production at several sites including Sandouville in northwestern France and Renault-owned Dacia plants in Romania on Saturday to prevent the spread of ransomware in its systems.

Nissan’s manufacturing plant in Sunderland, northeast England, was also affected by the cyber assault though “there has been no major impact on our business”, a spokesman for the Japanese carmaker said.German rail operator Deutsche Bahn [DBN.UL] said some electronic signs at stations announcing arrivals and departures were infected, with travelers posting pictures showing some bearing a message demanding a cash payment to restore access.

“UNPRECEDENTED” ATTACK EASES

Europol’s European Cybercrime Center said it was working closely with country investigators and private security firms to combat the threat and help victims. “The recent attack is at an unprecedented level and will require a complex international investigation to identify the culprits,” it said in a statement.

Some experts said the threat had receded for now, in part because a British-based researcher, who declined to give his name, registered a domain that he noticed the malware was trying to connect to, and so limited the worm’s spread.

“We are on a downward slope, the infections are extremely few, because the malware is not able to connect to the registered domain,” said Vikram Thakur, principal research manager at Symantec.

“The numbers are extremely low and coming down fast.”

But the attackers may yet tweak the code and restart the cycle. The researcher in Britain widely credited with foiling the ransomware’s proliferation told Reuters he had not seen any such tweaks yet, “but they will (happen).”

Researchers said the worm deployed in the latest attack, or similar tools released by Shadow Brokers, are likely to be used for fresh assaults not just with ransomware but other malware to break into firms, seize control of networks and steal data.

Finance chiefs from the Group of Seven rich countries were to commit on Saturday to joining forces to fight the growing threat of international cyber attacks, according to a draft statement of a meeting they are holding in Italy.

“Appropriate economy-wide policy responses are needed,” the ministers said in their draft statement, seen by Reuters.

HOSPITALS IN FIRING LINE

In Asia, some hospitals, schools, universities and other institutions were affected, though the full extent of the damage is not yet known because it is the weekend.

“I believe many companies have not yet noticed,” said William Saito, a cyber security adviser to Japan’s government. “Things could likely emerge on Monday” as staff return to work.

China’s information security watchdog said “a portion” of Windows systems users in the country were infected, according to a notice posted on the official Weibo page of the Beijing branch of the Public Security Bureau on Saturday. Xinhua state news agency said some secondary schools and universities were hit.

In Vietnam, Vu Ngoc Son, a director of Bkav Anti Malware, said dozens of cases of infection had been reported there, but he declined to identify any of the victims.

South Korea’s Yonhap news agency reported a university hospital had been affected, while a communications official in Indonesia said two hospitals there had been hit.

The most disruptive attacks were reported in Britain, where hospitals and clinics were forced to turn away patients after losing access to computers on Friday.

International shipper FedEx Corp said some of its Windows computers were also breached. “We are implementing remediation steps as quickly as possible,” a FedEx statement said.

Telecommunications company Telefonica was among many targets in Spain. Portugal Telecom and Telefonica Argentina both said they were also targeted.

Only a small number of U.S.-headquartered organizations were hit because the hackers appear to have begun the campaign by focusing on targets in Europe, said Thakur.

By the time they turned their attention to the United States, spam filters had identified the new threat and flagged the ransomware-laden emails as malicious, he added.

MICROSOFT BOLSTERS WINDOWS DEFENCES

Private security firms identified the ransomware as a new variant of “WannaCry” that had the ability to automatically spread across large networks by exploiting a known bug in Microsoft’s Windows operating system.

“This is one of the largest global ransomware attacks the cyber community has ever seen,” said Rich Barger, director of threat research with Splunk, one of the firms that linked WannaCry to the NSA.

The Shadow Brokers released Eternal Blue as part of a trove of hacking tools that they said belonged to the U.S. spy agency.

The attack targeted Windows computers that had not installed patches released by Microsoft in March, or older machines running software that Microsoft no longer supports and for which patches did not exist, including the 16-year-old Windows XP system, researchers said.

Microsoft said it pushed out automatic Windows updates to defend existing clients from WannaCry. It had issued a patch on March 14 to protect them from Eternal Blue. Late on Friday, Microsoft also released patches for a range of long discontinued software, including Windows XP and Windows Server 2003.

“Today our engineers added detection and protection against new malicious software known as Ransom:Win32.WannaCrypt,” Microsoft said in a statement on Friday, adding it was working with customers to provide additional assistance.

POLITICALLY SENSITIVE TIMING

The spread of the ransomware capped a week of cyber turmoil in Europe that began when hackers posted a trove of campaign documents tied to French candidate Emmanuel Macron just before a run-off vote in which he was elected president of France.

On Wednesday, hackers disrupted the websites of several French media companies and aerospace giant Airbus. The hack happened four weeks before a British general election in which national security and the management of the state-run National Health Service are important issues.

Authorities in Britain have been braced for cyber attacks in the run-up to the election, as happened during last year’s U.S. election and on the eve of the French run-off vote on May 7.

But those attacks – blamed on Russia, which has repeatedly denied them – followed a different modus operandi involving penetrating the accounts of individuals and political organizations and then releasing hacked material online.

On Friday, Russia’s interior and emergencies ministries, as well as its biggest bank, Sberbank, said they were targeted by ransomware. The interior ministry said about 1,000 computers had been infected but it had localized the virus.

Although cyber extortion cases have been rising for several years, they have to date affected small- to mid-sized organizations. “Seeing a large telco like Telefonica get hit is going to get everybody worried,” said Chris Wysopal, chief technology officer with cyber security firm Veracode.

UK government in dark over who behind cyber attack

LONDON (Reuters) – The British government does not yet know who was behind Friday’s global cyber attack that disrupted the country’s health system, interior minister Amber Rudd said on Saturday.

“We’re not able to tell you who’s behind the attack. That work is still ongoing,” she told BBC radio.

She said Britain’s National Cyber Security Center was working with the country’s health service to ensure the attack was contained, while the National Crime Agency was working with them to find out where it came from.

Rudd said the government did not know if the attack was directed by a foreign government.

On Friday, cyber extortionists tricked victims into opening malicious malware attachments to spam emails that appeared to contain invoices, job offers, security warnings and other legitimate files. Nearly 100 countries were impacted.

Rudd said the attack was not specifically targeted at Britain’s health service.

“(The virus) feels random in terms of where it’s gone to and where it’s been opened,” she said.

Though 45 health service organizations in England and Scotland were affected by malicious software, no patient data has been accessed or transferred, said Rudd.

The minister said lessons had to be learned from the attack.

“There will be lessons to learn … Why is it certain regions are affected more than others? Is it to do with the software? Is it to do with better IT?”

Separately on Saturday, finance chiefs from the Group of Seven rich countries will commit to join forces to fight the growing threat of international cyber attacks, according to a draft statement of a meeting they are holding in Bari, Italy.

Global cyber attack fuels concern about U.S. vulnerability disclosures

By Dustin Volz

WASHINGTON (Reuters) – A global cyber attack on Friday renewed concerns about whether the U.S. National Security Agency and other countries’ intelligence services too often hoard software vulnerabilities for offensive purposes, rather than quickly alerting technology companies to such flaws.

Hacking tools believed to belong to the NSA that were leaked online last month appear to be the root cause of a major cyber attack unfurling throughout Europe and beyond, security researchers said, stoking fears that the spy agency’s powerful cyber weapons had been stolen and repurposed by hackers with nefarious goals.

Some cyber security experts and privacy advocates said the massive attack reflected a flawed approach by the United States to dedicate more cyber resources to offense rather than defense, a practice they argued makes the internet less secure.

Across the U.S. federal government, about 90 percent of all spending on cyber programs is dedicated to offensive efforts, including penetrating the computer systems of adversaries, listening to communications and developing the means to disable or degrade infrastructure, senior intelligence officials told Reuters in March. (http://reut.rs/2o7qHqN)

“These attacks underscore the fact that vulnerabilities will be exploited not just by our security agencies, but by hackers and criminals around the world,” Patrick Toomey, a staff attorney with the American Civil Liberties Union, said in a statement.

The NSA did not respond to a request for comment.

Hospitals and doctors’ surgeries in parts of England on Friday were forced to turn away patients and cancel appointments after they were infected with the “ransomware”, which scrambled data on computers and demanded payments of $300 to $600 to restore access.

Security software maker Avast said it had observed more than 57,000 infections in 99 countries. Russia, Ukraine and Taiwan were the top targets, it said.

Private security firms identified the virus as a new variant of ‘WannaCry’ ransomware with the ability to automatically spread across large networks by exploiting a bug in Microsoft Corp’s Windows operating system.

Security experts said the ransomware used in the attacks leveraged a hacking tool found in a leak of documents in April by a group known as Shadow Brokers.

At the time, Microsoft acknowledged the vulnerabilities and said they had been patched in a series of earlier updates pushed to customers, the most recent of which had been rolled out only a month earlier in March. But the episode prompted concerns about whether the tools could be leveraged by hackers to attack unpatched systems.

In a statement, a Microsoft spokesman said on Friday its engineers had provided additional detection and protection services against the WannaCry malware and that it was working with customers to provide additional assistance. The spokesman reiterated that customers who have Windows Updates enabled and use the company’s free antivirus software are protected.

Shadow Brokers first emerged last year and began dumping tranches of documents that it said belonged to the NSA, though the files appeared at least a few years old.

Over time, western researchers have grown more confident that Russia may be behind Shadow Brokers and possibly other recent disclosures of sensitive information about cyber capabilities that have been pilfered from U.S. intelligence agencies.

Some researchers cast blame not on the NSA but on the hospitals and other customers that appeared to leave themselves open to attack.

“The main problem here is organizations taking more than eight weeks to patch once Microsoft released the update,” said Chris Wysopal, chief technology officer at the cyber firm Veracode. “Eight weeks is plenty of time for a criminal organization to develop a sophisticated attack on software and launch it on a wide scale.”

Former intelligence contractor Edward Snowden, who in 2013 leaked documents to journalists revealing the existence of broad U.S. surveillance programs, said on Twitter the NSA had built attack tools targeting U.S. software that “now threatens the lives of hospital patients.”

“Despite warnings, (NSA) built dangerous attack tools that could target Western software,” Snowden said. “Today we see the cost.”

Global cyber attack hits hospitals and companies, threat seen fading for now

The most disruptive attacks were reported in Britain, where hospitals and clinics were forced to turn away patients after losing access to computers on Friday.

International shipper FedEx Corp said some of its Windows computers were also infected. “We are implementing remediation steps as quickly as possible,” it said in a statement.

Telecommunications company Telefonica was among many targets in Spain. Portugal Telecom and Telefonica Argentina both said they were also targeted.

Only a small number of U.S.-headquartered organizations were hit because the hackers appear to have begun the campaign by targeting organizations in Europe, said Thakur.

By the time they turned their attention to the United States, spam filters had identified the new threat and flagged the ransomware-laden emails as malicious, Thakur added.

MICROSOFT UPS DEFENSES

The U.S. Department of Homeland Security said it was sharing information with domestic and foreign partners and was ready to lend technical support.

Private security firms identified the ransomware as a new variant of “WannaCry” that had the ability to automatically spread across large networks by exploiting a known bug in Microsoft’s Windows operating system.

The hackers, who have not come forward to claim responsibility or otherwise been identified, likely made it a “worm”, or self spreading malware, by exploiting a piece of NSA code known as “Eternal Blue” that was released last month by a group known as the Shadow Brokers, researchers with several private cyber security firms said.

“This is one of the largest global ransomware attacks the cyber community has ever seen,” said Rich Barger, director of threat research with Splunk, one of the firms that linked WannaCry to the NSA.

The Shadow Brokers released Eternal Blue as part of a trove of hacking tools that they said belonged to the U.S. spy agency.

Microsoft said it was pushing out automatic Windows updates to defend clients from WannaCry. It issued a patch on March 14 to protect them from Eternal Blue.

“Today our engineers added detection and protection against new malicious software known as Ransom:Win32.WannaCrypt,” Microsoft said in a statement on Friday, adding it was working with customers to provide additional assistance.

SENSITIVE TIMING

The spread of the ransomware capped a week of cyber turmoil in Europe that began the previous week when hackers posted a trove of campaign documents tied to French candidate Emmanuel Macron just before a run-off vote in which he was elected president of France.

On Wednesday, hackers disrupted the websites of several French media companies and aerospace giant Airbus.The hack happened four weeks before a British general election in which national security and the management of the state-run National Health Service are important issues.

The British government did not know who was behind the attack but its National Crime Agency was working to find out, interior minister Amber Rudd said.

Authorities in Britain have been braced for cyber attacks in the run-up to the election, as happened during last year’s U.S. election and on the eve of the French one.

But those attacks – blamed on Russia, which has repeatedly denied them – followed a different modus operandi involving penetrating the accounts of individuals and political organizations and then releasing hacked material online.

On Friday, Russia’s interior and emergencies ministries, as well as its biggest bank, Sberbank, said they were targeted. The interior ministry said about 1,000 computers had been infected but it had localized the virus.

Although cyber extortion cases have been rising for several years, they have to date affected small-to-mid sized organizations.

“Seeing a large telco like Telefonica get hit is going to get everybody worried,” said Chris Wysopal, chief technology officer with cyber security firm Veracode.

LONDON/MADRID (Reuters) – A global cyberattack leveraging hacking tools widely believed by researchers to have been developed by the U.S. National Security Agency hit international shipper FedEx, disrupted Britain’s health system and infected computers in nearly 100 countries on Friday.

Cyber extortionists tricked victims into opening malicious malware attachments to spam emails that appeared to contain invoices, job offers, security warnings and other legitimate files.

The ransomware encrypted data on the computers, demanding payments of $300 to $600 to restore access. Security researchers said they observed some victims paying via the digital currency bitcoin, though they did not know what percent had given in to the extortionists.

Researchers with security software maker Avast said they had observed 57,000 infections in 99 countries with Russia, Ukraine and Taiwan the top targets.

The most disruptive attacks were reported in Britain, where hospitals and clinics were forced to turn away patients after losing access to computers.

International shipper FedEx Corp said some of its Windows computers were also infected. “We are implementing remediation steps as quickly as possible,” it said in a statement.

Still, only a small number of U.S.-headquartered organizations were hit because the hackers appear to have begun the campaign by targeting organizations in Europe, said Vikram Thakur, research manager with security software maker Symantec.

By the time they turned their attention to the United States, spam filters had identified the new threat and flagged the ransomware-laden emails as malicious, Thakur said.

The U.S. Department of Homeland Security said late on Friday that it was aware of reports of the ransomware, was sharing information with domestic and foreign partners and was ready to lend technical support.

Telecommunications company Telefonica was among many targets in Spain, though it said the attack was limited to some computers on an internal network and had not affected clients or services. Portugal Telecom and Telefonica Argentina both said they were also targeted.

Private security firms identified the ransomware as a new variant of “WannaCry” that had the ability to automatically spread across large networks by exploiting a known bug in Microsoft’s Windows operating system.

“Once it gets in and starts moving across the infrastructure, there is no way to stop it,” said Adam Meyers, a researcher with cyber security firm CrowdStrike.

The hackers, who have not come forward to claim responsibility or otherwise been identified, likely made it a “worm,” or self spreading malware, by exploiting a piece of NSA code known as “Eternal Blue” that was released last month by a group known as the Shadow Brokers, researchers with several private cyber security firms said.

“This is one of the largest global ransomware attacks the cyber community has ever seen,” said Rich Barger, director of threat research with Splunk, one of the firms that linked WannaCry to the NSA.

“Today our engineers added detection and protection against new malicious software known as Ransom:Win32.WannaCrypt,” Microsoft said in a statement. It said the company was working with its customers to provide additional assistance.

SENSITIVE TIMING

The spread of the ransomware capped a week of cyber turmoil in Europe that kicked off a week earlier when hackers posted a huge trove of campaign documents tied to French candidate Emmanuel Macron just 1-1/2 days before a run-off vote in which he was elected as the new president of France.

On Wednesday, hackers disputed the websites of several French media companies and aerospace giant Airbus.Also, the hack happened four weeks before a British parliamentary election in which national security and the management of the state-run National Health Service (NHS) are important campaign themes.

Authorities in Britain have been braced for possible cyberattacks in the run-up to the vote, as happened during last year’s U.S. election and on the eve of this month’s presidential vote in France.

But those attacks – blamed on Russia, which has repeatedly denied them – followed an entirely different modus operandi involving penetrating the accounts of individuals and political organizations and then releasing hacked material online.

On Friday, Russia’s interior and emergencies ministries, as well as the country’s biggest bank, Sberbank, said they were targeted. The interior ministry said on its website that around 1,000 computers had been infected but it had localized the virus.

The emergencies ministry told Russian news agencies it had repelled the cyberattacks while Sberbank said its cyber security systems had prevented viruses from entering its systems.

NEW BREED OF RANSOMWARE

Although cyber extortion cases have been rising for several years, they have to date affected small-to-mid sized organizations, disrupting services provided by hospitals, police departments, public transportation systems and utilities in the United States and Europe.

“Seeing a large telco like Telefonica get hit is going to get everybody worried. Now ransomware is affecting larger companies with more sophisticated security operations,” Chris Wysopal, chief technology officer with cyber security firm Veracode, said.

The news is also likely to embolden cyber extortionists when selecting targets, Chris Camacho, chief strategy officer with cyber intelligence firm Flashpoint, said.

“Now that the cyber criminals know they can hit the big guys, they will start to target big corporations. And some of them may not be well prepared for such attacks,” Camacho said.

In Spain, some big firms took pre-emptive steps to thwart ransomware attacks following a warning from Spain’s National Cryptology Centre of “a massive ransomware attack.”

Iberdrola and Gas Natural, along with Vodafone’s unit in Spain, asked staff to turn off computers or cut off internet access in case they had been compromised, representatives from the firms said.

In Spain, the attacks did not disrupt the provision of services or networks operations of the victims, the government said in a statement.

LONDON (Reuters) – Hospitals across England were being forced to divert emergency cases on Friday after suffering a suspected national cyber attack.

Among them was the Barts Health group which manages major central London hospitals including The Royal London and St Bartholomew’s.

“We are experiencing a major IT disruption and there are delays at all of our hospitals,” it said.

“We have activated our major incident plan to make sure we can maintain the safety and welfare of patients. Ambulances are being diverted to neighboring hospitals.”

Patients requiring emergency treatment across England were diverted away from the hospitals affected and the public was advised to only seek medical care for acute medical conditions.

Reuters was unable to independently verify whether the hospitals were the subject of a concerted cyber attack ahead of the June 8 election.

Britain’s National Crime Agency said it was aware of the reports of a cyber attack but made no further comment.

The National Health Service (NHS) said it was responding to the incidents.

“We are aware of a cyber security incident and we are working on a response,” said a spokesman for NHS Digital, a division of the NHS which handles information technology issues.

There was no immediate comment from the Health Ministry.

Earlier on Friday, Spain’s government warned that a large number of companies had been attacked by cyber criminals who infected computers with malicious software known as “ransomware” that locks up computers and demands ransoms to restore access.
