(Reuters) – Anthem Inc <ANTM.N>, the largest U.S. health insurance company, has agreed to settle litigation over hacking in 2015 that compromised about 79 million people’s personal information for $115 million, which lawyers said would be the largest settlement ever for a data breach.

The deal, announced Friday by lawyers for people whose information was compromised, must still be approved by U.S. District Judge Lucy Koh in San Jose, California, who is presiding over the case.

The money will be used to pay for two years of credit monitoring for people affected by the hack, the lawyers said. Victims are believed to include current and former customers of Anthem and of other insurers affiliated with Anthem through the national Blue Cross Blue Shield Association.

People who are already enrolled in credit monitoring may choose to receive cash instead, which may be up to $50 per person, according to a motion filed in California federal court Friday.

“We are very satisfied that the settlement is a great result for those affected and look forward to working through the settlement approval process,” Andrew Friedman, a lawyer for the victims, said in a statement.

The credit monitoring in the settlement is in addition to the two years of credit monitoring Anthem offered victims when it announced the breach in February 2015, according to Anthem spokeswoman Jill Becher, who said the company was pleased to be resolving the litigation.

The Indianapolis-based company did not admit wrongdoing, and there was no evidence any compromised information was sold or used to commit fraud, Becher said.

Anthem said in February 2015 that an unknown hacker had accessed a database containing personal information, including names, birthdays, social security numbers, addresses, email addresses and employment and income information. The attack did not compromise credit card information or medical information, the company said.

More than 100 lawsuits filed against Anthem over the breach were consolidated before Judge Koh.

The breach is one of a series of high-profile data breaches that resulted in losses of hundreds of millions of dollars to U.S. companies in recent years, including Target Corp <TGT.N>, which agreed to pay $18.5 million to settle claims by 47 states in May, and Home Depot Inc <HD.N>, which agreed to pay at least $19.5 million to consumers last year.

Google to push for law enforcement to have more access to overseas data

By Dustin Volz

WASHINGTON (Reuters) – Alphabet Inc’s <GOOGL.O> Google will press U.S. lawmakers on Thursday to update laws on how governments access customer data stored on servers located in other countries, hoping to address a mounting concern for both law enforcement officials and Silicon Valley.

The push comes amid growing legal uncertainty, both in the United States and across the globe, about how technology firms must comply with government requests for foreign-held data. That has raised alarm that criminal and terrorism investigations are being hindered by outdated laws that make the current process for sharing information slow and burdensome.

Kent Walker, Google’s senior vice president and general counsel, will announce the company’s framework during a speech in Washington, D.C., at the Heritage Foundation, a conservative think tank that wields influence in the Trump White House and Republican-controlled Congress.

The speech urges Congress to update a decades-old electronic communications law and follows similar efforts by Microsoft Corp <MSFT.O>.

Both companies had previously objected in court to U.S. law enforcement efforts to use domestic search warrants for data held overseas because the practice could erode user privacy. But the tech industry and privacy advocates have also admitted the current rules for appropriate cross-border data requests are untenable.

The Mountain View, California-based company calls for allowing countries that commit to baseline privacy, human rights and due process principles to directly request data from U.S. providers without the need to consult the U.S. government as an intermediary. It is intended to be reciprocal.

Countries that do not adhere to the standards, such as an oppressive regime, would not be eligible.

Google did not detail specific baseline principles in its framework.

“This couldn’t be a more urgent set of issues,” Walker said in an interview, noting that recent acts of terrorism in Europe underscored the need to move quickly.

Current agreements that allow law enforcement access to data stored overseas, known as mutual legal assistance treaties, involve a formal diplomatic request for data and require the host country obtain a warrant on behalf of the requesting country. That can often take several months.

In January, a divided federal appeals court refused to reconsider its decision from last year that said the U.S. government could not force Microsoft or other companies to hand over customer data stored abroad under a domestic warrant.

The U.S. Justice Department has until midnight on Friday to appeal that decision to the Supreme Court. It did not respond to a request for comment.

U.S. judges have ruled against Google in similar recent cases, however, elevating the potential for Supreme Court review.

Companies, privacy advocates and judges themselves have urged Congress to address the problem rather than leave it to courts.

Google will also ask Congress to codify warrant requirements for data requests that involve content, such as the actual message found within an email.

Chris Calabrese, vice president of policy at the Center for Democracy & Technology, said Google’s framework was “broadly correct” but urged caution about the process for letting countries make direct requests to providers.

“We need to make sure the people in the club are the right people,” he said.

U.S. banks, corporations establish principles for cyber risk ratings firms

By Anna Irrera and Olivia Oran

(Reuters) – More than two dozen U.S. companies, including several big banks, have teamed up to establish shared principles that would allow them to better understand their cyber security ratings and to challenge them if necessary, the U.S. Chamber of Commerce said on Tuesday. Large corporations often use the ratings, the cyber equivalent of a FICO credit score, to assess how prepared the companies they work with are to withstand cyber attacks. Insurers also look at the ratings when they make underwriting decisions on cyber liability.

The group includes big banks like JPMorgan Chase & Co <JPM.N>, Goldman Sachs Group Inc <GS.N> and Morgan Stanley <MS.N>, as well as non-financial companies like coffee retailer Starbucks Corp <SBUX.O>, health insurer Aetna Inc <AET.N> and home improvement chain Home Depot Inc <HD.N>. They are organizing the effort through the Chamber of Commerce, a broad trade group for corporate America.

The move comes in response to the emergence of such startups as BitSight Technologies, RiskRecon and SecurityScorecard that collect and analyze large swaths of data to rate companies on cyber security.

As these startups have gained prominence and venture capital funding, the companies they rate have complained of a lack of transparency.

“The challenge is that their (startups’) methodologies are proprietary and there hasn’t been transparency on how they go about creating the ratings,” JPMorgan Global Chief Information Security Officer Rohan Amin said in an interview.

The financial services industry is among the most vulnerable to cyber crime because of the massive amount of money and valuable data that banks, brokerages and investment firms process each day. Several technology companies, including Microsoft Corp <MSFT.O> and Verizon Communications Inc <VZ.N>, also support the principles being developed, as do the cyber ratings firms, the Chamber of Commerce said.

Ratings issued by those companies could help guide the standards being set by U.S. corporations. BitSight, for example, rates companies on a scale of 250 to 900 with a higher rating indicating better security performance.

“For organizations to use your platform you have to demonstrate trustworthiness and reliability,” said Jake Olcott, BitSight’s vice president of strategic partnerships.

Canada cyber-spy agency expects hacktivist attacks in 2019 vote

OTTAWA/TORONTO (Reuters) – Canada’s electronic spy agency said on Friday it was “very likely” that hackers will try to influence Canada’s 2019 elections and it planned to advise political parties next week on how to guard against cyber threats.

The Communications Security Establishment (CSE) agency said it had not detected any nation-state attempts to interfere in prior Canadian elections but saw risk from hacktivists.

CSE said Canada’s 2015 federal election, which brought Prime Minister Justin Trudeau’s Liberals to power, was targeted by “low-sophistication cyber threat activity” that did not affect the outcome of the election, according to a report it released on Friday.

“CSE will be offering cyber advice and guidance to parliamentarians and to Canada’s political parties,” CSE chief Greta Bossenmaier told a news conference. “Cyber security is a team imperative; no one organization can go it alone,” she added.

Worries about interference in democratic processes have come to the fore amid allegations of Russian meddling in the U.S. presidential election last November and the French election in May.

U.S. intelligence agencies concluded last year that Russia hacked and leaked Democratic Party emails as part of an effort to tilt the presidential election in favor of Donald Trump, something Russia denies.

A British intelligence agency in March told political parties to protect themselves against potential cyber attacks, while the French government in March dropped plans to let its citizens abroad vote electronically in this month’s legislative elections because of concern about the risk of cyber attacks.

CSE said federal political parties, politicians and the media are more vulnerable to cyber threats than elections themselves, given that federal elections are largely paper-based.

Cyber security lawyer Imran Ahmed of Miller Thomson said engaging with political parties was “a good first step” but the spy agency should have already had a plan in place including expected standards for political parties to meet.

“We’re two years away from 2019 and there’s no timeline for what the next steps will be,” he said.

CSE said it expects some hacktivist efforts in 2019 will be well-planned, with targets ranging from voter suppression and stealing party information to trying to discredit candidates.

Security firms warn of new cyber threat to electric grid

An electricity station with high-tension electricity power lines is seen in Galapagar, Spain, January 20, 2017.

By Jim Finkle

(Reuters) – Two cyber security companies said they have uncovered a sophisticated piece of malicious software capable of causing power outages by ordering industrial computers to shut down electricity transmission.

Analysis of the malware, known as Crash Override or Industroyer, indicates it was likely used in a December 2016 cyber attack that cut power in Ukraine, according to the firms, Slovakian security software maker ESET and U.S. critical-infrastructure security firm Dragos Inc.

The discovery may stoke fears about cyber vulnerabilities in power grids that have intensified in the wake of the December Ukraine attack, and one a year earlier that also cut power in that nation.

Ukraine authorities have previously blamed Russia for the attacks on its grid. Moscow has denied responsibility.

Dragos founder Robert M. Lee said the malware is capable of causing outages of up to a few days in portions of a nation’s grid, but is not potent enough to bring down a country’s entire grid.

The firm has alerted government authorities and power companies about the threat, advising them of steps to defend against the threat, Lee said in an interview.

Crash Override can be detected if a utility specifically monitors its network for abnormal traffic, including signs that the malware is searching for the location of substations or sending messages to switch breakers, according to Lee, a former U.S. Air Force warfare operations officer.

The sample of Crash Override that was analyzed by Dragos is capable of attacking power operators across Europe, according to Lee.

“With small modifications, it could be leveraged against the United States,” he said.

Reuters reviewed an ESET technical analysis of the malware provided by the security firm, which they planned to release publicly on Monday. An ESET spokeswoman said the firm’s researchers were not available for comment ahead of its release.

ESET said in its report that it believed the malware was “very probably” used in the 2016 attack in Ukraine, noting it has an activation time stamp of Dec. 17, the day of the outage.

Crash Override is the second piece of malware discovered to date that is capable of disrupting industrial processes, according to Lee.

The first, Stuxnet, was discovered in 2010 and is widely believed by security researchers to have been used by the United States and Israel to attack Iran’s nuclear program.

Malware has been used in other attacks on industrial targets, including the 2015 Ukraine power outage, but in those cases human intervention was required to interfere with operations, Lee said.

Blame game for cyber attacks grows murkier as spying, crime tools mix

By Eric Auchard

TALLINN, Estonia (Reuters) – Veteran espionage researcher Jon DiMaggio was hot on the trail three months ago of what on the face of it looked like a menacing new industrial espionage attack by Russian cyber spies.

All the hallmarks were there: targeted phishing emails common to government espionage, an advanced Trojan horse for stealing data from inside organizations, covert communication channels for grabbing documents and clues in the programming code indicating its authors were Russian speakers.

It took weeks before the lead cyber spying investigator at Symantec, a top U.S. computer security firm, figured out instead he was tracking a lone-wolf cyber criminal.

DiMaggio won’t identify the name of the culprit, whom he has nicknamed Igor, saying the case is a run-of-the-mill example of increasing difficulties in separating national spy agency activity from cyber crime. The hacker comes from Transdniestria, a disputed, Russian-speaking region of Moldova, he said.

“The malware in question, Trojan.Bachosens, was so advanced that Symantec analysts initially thought they were looking at the work of nation-state actors,” DiMaggio told Reuters in a phone interview on Wednesday. “Further investigation revealed a 2017 equivalent of the hobbyist hackers of the 1990s.”

Reuters could not contact the alleged hacker.

The example highlights the dangers of jumping to conclusions in the murky world of cyber attack and defense, as tools once only available to government intelligence services find their way into the computer criminal underground.

Security experts refer to this as “the attribution problem”, using technical evidence to assign blame for cyber attacks in order to take appropriate legal and political responses.

These questions echo through the debate over whether Russia used cyber attacks to influence last year’s U.S. presidential elections and whether Moscow may be attempting to disrupt national elections taking place in coming months across Europe.

The topic is a big talking point for military officials and private security researchers at the International Conference on Cyber Conflict in Tallin this week. It has been held each year since Estonia was swamped in 2007 by cyber attacks that took down government, financial and media websites amid a dispute with Russia. Attribution for those attacks remains disputed.

THE SMOKING GUN

“Attribution is almost never a clean, smoking-gun,” said Paul Vixie, creator of the first commercial anti-spam service, whose latest firm, Farsight Security, helps firms track down cyber attackers to identify and block them.

Raising the stakes, a mystery group calling itself ShadowBrokers has taken credit for leaking cyber-spying tools that are now being turned to criminal use, including ones used in the recent WannaCry global ransomware attack, ratcheting up cyber security threats to a whole new level.

In recent weeks, ShadowBrokers has threatened to sell more such tools, believed to have been stolen from the U.S. National Security Agency, to enable hacking into the world’s most used computers, software and phones. (http://reut.rs/2rmTZmm)

“The bar for what’s considered advanced is lowered as time goes by,” said Sean Sullivan, a security researcher with Finnish cyber firm F-Secure.

The Moldovan hacker’s campaign to steal data and resell it on the web came to light only after infections popped up last year at a major airline, an online gambling firm and a Chinese automotive software maker, which are all customers of Symantec products used to secure their business networks.

Igor appears to have targeted the auto-tech company to steal its car diagnostics software, which retails for around $1,100 but Igor sold for just a few hundred dollars on underground forums and websites he had created. His aims in trying to break into the airline and gambling firm remain a mystery.

“Considering the audacity of this attack, the financial rewards for Igor are pretty low,” DiMaggio wrote in a blog post on his findings to be published on Wednesday.

As a threat, Symantec rates Trojan.Bachosens as a very low risk virus, in part because the attack singles out only a handful of specific firms rather than the wide-ranging, random attacks used by many cyber criminals to scoop up the greatest number of victims.

“I think those days are over when we can say in black and white: We know this is an espionage group,” DiMaggio said.

The Symantec researcher has not reported Igor to local authorities, calculating that exposing the methods of the attack will be enough to neutralize them.

China to implement cyber security law from Thursday

SHANGHAI (Reuters) – China, battling increased threats from cyber-terrorism and hacking, will adopt from Thursday a controversial law that mandates strict data surveillance and storage for firms working in the country, the official Xinhua news agency said.

The law, passed in November by the country’s largely rubber-stamp parliament, bans online service providers from collecting and selling users’ personal information, and gives users the right to have their information deleted, in cases of abuse.

“Those who violate the provisions and infringe on personal information will face hefty fines,” the news agency said on Monday, without elaborating.

Reuters reported this month that overseas business groups were pushing Chinese regulators to delay implementation of the law, saying the rules would severely hurt activities.

Until now, China’s data industry has had no overarching data protection framework, being governed instead by loosely defined laws.

However, overseas critics say the new law threatens to shut foreign technology companies out of sectors the country deems “critical”, and includes contentious requirements for security reviews and data stored on servers in China.

Chipotle says hackers hit most restaurants in data breach

By Lisa Baertlein

(Reuters) – Hackers used malware to steal customer payment data from most of Chipotle Mexican Grill Inc’s <CMG.N> restaurants over a span of three weeks, the company said on Friday, adding to woes at the chain whose sales had just started recovering from a string of food safety lapses in 2015.

Chipotle said it did not know how many payment cards or customers were affected by the breach that struck most of its roughly 2,250 restaurants for varying amounts of time between March 24 and April 18, spokesman Chris Arnold said via email.

A handful of Canadian restaurants were also hit in the breach, which the company first disclosed on April 25.

Stolen data included account numbers and internal verification codes. The malware has since been removed.

The information could be used to drain debit card-linked bank accounts, make “clone” credit cards, or to buy items on certain less-secure online sites, said Paul Stephens, director of policy and advocacy at the non-profit Privacy Rights Clearinghouse.

The breach could once again threatens sales at its restaurants, which only recently recovered after falling sharply in late 2015 after Chipotle was linked to outbreaks of E. coli, salmonella and norovirus that sickened hundreds of people.

An investigation into the breach found the malware searched for data from the magnetic stripe of payment cards.

Arnold said Chipotle could not alert customers directly as it did not collect their names and mailing addresses at the time of purchase.

The company posted notifications on the Chipotle and Pizzeria Locale websites and issued a news release to make customers aware of the incident.

Linn Freedman, an attorney at Robinson & Cole LLP specializing in data breach response, said Chipotle was putting the burden on the consumer to discover possible fraudulent transactions by notifying them through the websites.

“I don’t think you will get to all of the customers who might have been affected,” she said.

Security analysts said Chipotle would likely face a fine based on the size of the breach and the number of records compromised.

“If your data was stolen through a data breach that means you were somewhere out of compliance” with payment industry data security standards, Julie Conroy, research director at Aite Group, a research and advisory firm.

“In this case, the card companies will fine Chipotle and also hold them liable for any fraud that results directly from their breach,” said Avivah Litan, a vice president at Gartner Inc <IT.N> specializing in security and privacy.

Chipotle did not immediately comment on the prospect of a fine.

Retailer Target Corp <TGT.N> in 2017 agreed to pay $18.5 million to settle claims stemming from a massive data breach in late 2013.

Hotels and restaurants have also been hit. They include Trump Hotels, InterContinental Hotels Group <IHG.L> as well as Wendy’s <WEN.O>, Arby’s and Landry’s restaurants.

Shares in Chipotle Mexican Grill ended marginally lower at $480.15 on Friday following the announcement.

Symantec says ‘highly likely’ North Korea group behind ransomware attacks

By Joseph Menn

SAN FRANCISCO (Reuters) – Cyber security firm Symantec Corp <SYMC.O> said on Monday it was “highly likely” a hacking group affiliated with North Korea was behind the WannaCry cyber attack this month that infected more than 300,000 computers worldwide and disrupted hospitals, banks and schools across the globe.

Symantec researchers said they had found multiple instances of code that had been used both in the North Korea-linked group’s previous activity and in early versions of WannaCry.

In addition, the same Internet connection was used to install an early version of WannaCry on two computers and to communicate with a tool that destroyed files at Sony Pictures Entertainment. The U.S. government and private companies have accused North Korea in the 2014 Sony attack.

North Korea has routinely denied any such role. On Monday, it called earlier reports that it might have been behind the WannaCry attack “a dirty and despicable smear campaign.”

Lazarus is the name many security companies have given to the hacking group behind the Sony attack and others. By custom, Symantec does not attribute cyber campaigns directly to governments, but its researchers did not dispute the common belief that Lazarus works for North Korea.

In a blog post, Symantec listed numerous links between Lazarus and software the group had left behind after launching an earlier, less virulent, version of the malware in February. One was a variant of software used to wipe disks during the Sony Pictures attack, while another tool used the same internet addresses as two other pieces of malware linked to Lazarus.

At the same time, flaws in the WannaCry code, its wide spread, and its demands for payment in the electronic bitcoin before files are decrypted suggest that the hackers were not working for North Korean government objectives in this case, said Vikram Thakur, Symantec’s security response technical director.

“Our confidence is very high that this is the work of people associated with the Lazarus Group, because they had to have source code access,” Thakur said in an interview.

But he added: “We don’t think that this is an operation run by a nation-state.”

With WannaCry, Thakur said, Lazarus Group members could have been moonlighting to make extra money, or they could have left government service, or they could have been contractors without direct obligations to serve only the government.

The most effective version of WannaCry spread by using a flaw in Microsoft’s Windows and a program that took advantage of it that had been used by the U.S. National Security Agency, officials said privately.

That program was among a batch leaked or stolen and then dumped online by a group calling itself The Shadow Brokers, who some in U.S. intelligence believe to be affiliated with Russia.

Analysts have been weighing in with various theories on the identity of those behind WannaCry, and some early evidence had pointed to North Korea. The Shadow Brokers endorsed that theory, perhaps to take heat off their own government backers for the disaster.

Cybersecurity company Kaspersky has said it had found several similarities between the WannaCry malware from the earlier attack and those used by Lazarus. But in an interview last week, its Asia research director, Vitaly Kamluk, said it was not conclusive evidence. “It’s unusual,” he said.

Beau Woods, deputy director of the Cyber Statecraft Initiative at the Atlantic Council, said that the Korean language used in some versions of the WannaCry ransom note was not that of a native speaker, making a Lazarus connection unlikely.

But Thakur said that some hackers deliberately obfuscate their language to make tracing them harder. It is also possible that the writer in question was a contractor in another country, he said.

Thakur said a less likely scenario is that Lazarus’ main aim was to create chaos by distributing WannaCry.

If the hackers’ main objective was to earn money on the side, that would suggest an undisciplined hacking operation run by North Korea, one that could be exploited and weakened by the country’s many foes.

“The intelligence community will probably take away from this that there is a possibility of splinters in the Lazarus Group, or members who are interested in filling their own pockets, and that could help,” Thakur said.

Lazarus has also been linked to attacks on banks using their SWIFT messaging network. Last year, hackers stole $81 million from Bangladesh’s central bank. Symantec said malware used in that attack was linked to Lazarus.

Newly discovered vulnerability raises fears of another WannaCry

FILE PHOTO: A hooded man holds a laptop computer as blue screen with an exclamation mark is projected on him in this illustration picture taken on May 13, 2017. REUTERS/Kacper Pempel/Illustration

SINGAPORE (Reuters) – A newly found flaw in widely used networking software leaves tens of thousands of computers potentially vulnerable to an attack similar to that caused by WannaCry, which infected more than 300,000 computers worldwide, cybersecurity researchers said on Thursday.

The U.S. Department of Homeland Security on Wednesday announced the vulnerability, which could be exploited to take control of an affected computer, and urged users and administrators to apply a patch.

Rebekah Brown of Rapid7, a cybersecurity company, told Reuters that there were no signs yet of attackers exploiting the vulnerability in the 12 hours since its discovery was announced.

But she said it had taken researchers only 15 minutes to develop malware that made use of the hole. “This one seems to be very, very easy to exploit,” she said.

Rapid7 said it had found more than 100,000 computers running vulnerable versions of the software, Samba, free networking software developed for Linux and Unix computers. There are likely to be many more, it said in response to emailed questions.

Most of the computers found are running older versions of the software and cannot be patched, said Brown.

Some of the computers appear to belong to organizations and companies, she said, but most were home users.

The vulnerability could potentially be used to create a worm like the one which allowed WannaCry to spread so quickly, Brown said, but that would require an extra step for the attacker.

Cybersecurity researchers have said they believe North Korean hackers were behind the WannaCry malware, which encrypted data on victims’ computers and demanded bitcoin in return for a decryption key.
