NEW YORK/LONDON (Reuters) – Companies without cyber insurance are dusting off policies covering kidnap, ransom and extortion in the world’s political hotspots to recoup losses caused by ransomware viruses such as “WannaCry”, insurers say.

Cyber insurance can be expensive to buy and is not widely used outside the United States, with one insurer previously describing the cost as $100,000 for $10 million in data breach insurance.

Some companies do not even consider it because they do not think they are targets.

The kidnap policies, known as K&R coverage, are typically used by multinational companies looking to protect their staff in areas where violence related to oil and mining operations is common, such as parts of Africa and Latin America. Companies could also tap them to cover losses following the WannaCry attack, which used malicious software, known as ransomware, to lock up more than 200,000 computers in more than 150 countries, and demand payments to free them up. Pay-outs on K&R for ransomware attacks may be lower and the policies less suitable than those offered by traditional cyber insurance, insurers say.

“There will be some creative forensic lawyers who will be looking at policies,” said Patrick Gage, chief underwriting officer at CNA Hardy, a specialist commercial insurer, in London.

He added, however, that given that K&R policies are geared towards a threat to lives, “our absolute preference is that people buy specific cover, rather than relying on insurance coverage that is not specific”.

American International Group Inc, Hiscox Ltd and the Travelers Companies Inc have been receiving ransomware claims from some customers with K&R policies as ransomware attacks become more common, the companies said.

The insurers declined to comment on total claims, citing confidentiality and client security concerns.

“We are seeing claims (over the past 18 months) but not a huge uptick,” a Hiscox spokeswoman said. “These are within expectations and entirely manageable.”

She declined to say whether the firm had seen any such claims from the WannaCry attacks though Tom Harvey, an expert in cyber risk management at catastrophe modeling firm RMS, said “insurers with kidnap and ransom books will want to look closely at their policy wordings to see whether they are exposed.”

A sharp rise in ransomware attacks in the past 18 months has driven companies to use K&R policies to cover some of their damages if they do not have direct cyber coverage or cannot meet initial cyber policy deductible costs, insurers said.

Symantec Corp,, a cyber security firm based in Mountain View in California, observed over 460,000 ransomware attempts in 2016, up 36 percent from 2015, the company said. The average payment demand ballooned from $294 to $1,077, a 266 percent increase. But as the threat mounts, K&R insurers are at risk from steeper claims than they had anticipated. They are responding by making changes to their policies, which were not designed around ransomware, insurance brokers said. MORE DAMAGING THEN KIDNAPPING Most of the computers affected by WannaCry were outside the United States, where companies have been slow to buy cyber insurance. Nearly 90 percent of the world’s annual cyber insurance premium of $2.5-3 billion comes from the U.S. market, according to insurance broker Aon Plc.

Global companies typically buy K&R policies without ransomware in mind. But instances of high-tech hacks and online ransom demands can hit a company’s business more than an executive being held hostage.

“If your CFO (chief financial officer) gets kidnapped, the company is going to continue to function,” said Bob Parisi, cyber product leader for insurance broker Marsh & McLennan Companies Inc.

“If you get a get a piece of malware in the system, you might have two factories that stop working. The actual damage is probably greater.”

The K&R policies, which typically do not have deductibles, cover the ransom payments as well as crisis response services, including getting in touch with criminal and regulatory authorities, said Kevin Kalinich, global head of Aon’s cyber risk practice.

Still, K&R policies may provide only a quick fix since they were not designed for ransomware. Companies can add coverage for business interruption, but the upper limits for pay-outs are usually lower than for a cyber policy, insurers say.

K&R insurers have been adapting to ransomware-related claims – some are modernizing coverage by setting up Bitcoin accounts for clients to speed up ransom payments, brokers said.

But insurers are mindful of their own risks.

Some have added deductibles, said Anthony Dagostino, head of global cyber risk at Willis Towers Watson PLC advisory and brokerage.

AIG has reduced business interruption coverage available for K&R policies to a $1 million maximum, from much higher and more flexible limits, said Tracie Grella, global head of cyber risk insurance at AIG.

“Insurers didn’t anticipate there would be this much ransomware activity,” Grella said.

Bitcoin’s murkier rivals line up to displace it as cybercriminals’ favourite

LONDON (Reuters) – Bitcoin is well-entrenched as the preferred payment for cybercriminals like the WannaCry hackers who have hit more than 300,000 computers over the past week, but cryptocurrencies offering more anonymity are threatening to displace it.

A key reason for bitcoin’s dominance in the nefarious online underworld, say technologists and cybercrime experts, is its size – the total value of all bitcoins in circulation is more than twice that of the nearest of hundreds of rivals.

That makes it easy for victims to access enough to pay the ransoms demanded, and for hackers to cash out of it via online exchanges to spend money in the real world.

Bitcoin was set up in 2008 by someone – or some group – calling themselves Satoshi Nakamoto, and was the first digital currency to successfully use cryptography to keep transactions secure and hidden, making traditional financial regulation difficult if not impossible.

Money is sent from one anonymous online “wallet” to another with no need for a third party to validate or clear the transactions.

In the WannaCry attack, the addresses of three anonymous bitcoin wallets were given to victims, with a demand for ransom payments from $300 worth of bitcoin, with a promise the affected machines would be decrypted in return, a promise that no evidence has shown will be kept.

But since the way that Bitcoin functions is via the blockchain – a giant, virtually tamper-proof, shared ledger of all bitcoin transactions ever made – payments can be traced, if users do not have the sophistication to take further steps to cloak themselves using digital anonymity tools.

“In the initial days of bitcoin, people…didn’t realise they were recording for posterity on the blockchain every financial transaction that ever took place,” said Emin Gun Sirer, a computer science professor at Cornell University.

Bitcoin addresses are anonymous, but users can be traced through IP addresses or by analysing money flows.

If criminals using bitcoin want to stay truly anonymous, Gun Sirer said, they have to go through a number of additional, complex steps to make sure they do not get caught.

It is not yet clear what level of sophistication the WannaCry hackers have when it comes to laundering their cryptocurrency, as none of the money has yet been moved out of the three bitcoin wallets linked to the ransomware, which have had over $80,000 worth of bitcoin paid into them so far.

But some have suggested that the fact that the WannaCry hackers demanded bitcoin shows how amateur they are.

“If it was me, I would want people to use bitcoin all day, because you can trace it,” said Luke Wilson, vice president for law enforcement at Elliptic, a London-based security firm that tracks illicit bitcoin transactions and that counts the U.S. Federal Bureau for Investigations (FBI) among its clients.

Wilson, who used to work at the FBI, where he set up a taskforce to investigate the use of virtual currencies, did not disclose all the ways that Elliptic and law enforcement agencies find criminals using bitcoin. But sometimes, he said, the offenders make as obvious a mistake as withdrawing money from a bitcoin wallet directly into their bank accounts.

CAT-AND-MOUSE GAME

More sophisticated criminals use obfuscation methods that make it very hard to be tracked down. One of the most basic ones is a technique known as “chain-hopping”, whereby money is moved from one cryptocurrency into another, across digital currency exchanges – the less-regulated the better – to create a money trail that is almost impossible to track.

Newer and more complex money-laundering methods have also emerged in recent years, which make it very difficult for law enforcement and bitcoin security firms such as Elliptic or New-York-based Chainalysis to track down cybercriminals.

“It’s a cat-and-mouse game – as police and companies like Elliptic catch up to criminals’ techniques, they invent new techniques,” said Jerry Brito, executive director of the Washington, D.C.-based Coin Center, a not-for-profit advocacy group focusing on public policy issues around cryptocurrency.

These techniques are not foolproof, however – chain-hopping, for example, relies on unregulated exchanges that do not carry out know-your-customer (KYC) checks, and security firms say they will develop ways to trace such methods.

MONERO HACK

Easier, perhaps, would be for cybercriminals to use next-generation cryptocurrencies that have built-in anonymity from the start, such as Monero, Dash and Z-Cash.

And indeed, experts said late on Tuesday that a computer virus that exploits the same vulnerability as the WannaCry attack had latched on to more than 200,000 computers and begun using them to manufacture – or “mine” – Monero currency.

But with a total value of around $425 million – a little over 1 percent of that of bitcoin – converting that currency into spendable cash might not be so easy, and it is also much harder for victims to access, alternative payments experts said.

That is why the Monero attack did not demand a ransom, but rather used the infected computers’ computing power to create new currency.

“This used to happen in bitcoin before it became big – there were loads of botnets that went into computers that used to mine bitcoin, but you now can’t basically mine bitcoin on normal computers because you need specialist hardware,” said Chainalysis CEO Jonathan Levin.

Levin said such bitcoin-based attacks were carried out several years ago, when mining it was still largely a hobby for tech geeks using their home computers.

As the bitcoin price has risen and as transaction numbers have grown, the computers have become so specialized that only they can only perform the function of bitcoin mining.

“If Monero does become adopted and is as big and liquid (as bitcoin), that means the crime (will) move from using computers to mine to getting to extortion,” Levin said.

French researchers find last-ditch cure to unlock WannaCry files

FRANKFURT (Reuters) – French researchers said on Friday they had found a last-chance way for technicians to save Windows files encrypted by WannaCry, racing against a deadline as the ransomware threatens to start locking up victims’ computers first infected a week ago.

WannaCry, which started to sweep round the globe last Friday and has infected more than 300,000 computers in 150 nations, threatens to lock out victims who have not paid a sum of $300 to $600 within one week of infection.

A loose-knit team of security researchers scattered across the globe said they had collaborated to develop a workaround to unlock the encryption key for files hit in the global attack, which several independent security researchers have confirmed.

The researchers warned that their solution would only work in certain conditions, namely if computers had not been rebooted since becoming infected and if victims applied the fix before WannaCry carried out its threat to lock their files permanently.

The group includes Adrien Guinet, who works as a security expert, Matthieu Suiche, who is an internationally known hacker, and Benjamin Delpy, who helped out by night, in his spare time, outside his day job at the Banque de France.

Suiche has published a blog with technical details summarizing what the group of passing online acquaintances has developed. He links to a tool called Wannakey built by Guinet, the creator of the original concept.

“THE ONLY WORKABLE SOLUTION”

Guinet, a security researcher at Paris-based Quarks Lab, published the basic technique for decrypting WannaCry files on Thursday, which Delpy then figured out how to turn into a practical tool to salvage files.

Suiche, based in the United Arab Emirates and one of the world’s top security researchers, provided advice and testing to ensure the fix worked across all various versions of Windows.

Wannakey was quickly tested and shown to work on Windows 7 and older Windows versions XP and 2003, Suiche said, adding that he believes the hastily developed fix also works with Windows 2008 and Vista.

“(The method) should work with any operating system from XP to Win7,” Suiche told Reuters via direct message on Twitter.

“This is not a perfect solution. But this is so far the only workable solution to help enterprises to recover their files if they have been infected and have no back-ups,” Suiche said of network back-up and retrieval systems which allow users with infected computers to restore them after re-imaging their PCs.

Classic customer help desk procedures typically advise users reporting computer problems to reboot their machines, but fast-acting users who pulled the plug on their PCs or otherwise did not attempt to repair them can benefit, the researchers said.

Hackers mint crypto-currency with technique in global ‘ransomware’ attack

SAN FRANCISCO (Reuters) – A computer virus that exploits the same vulnerability as the global “ransomware” attack has latched on to more than 200,000 computers and begun manufacturing digital currency, experts said Tuesday.

The development adds to the dangers exposed by the WannaCry ransomware and provides another piece of evidence that a North Korea-linked hacking group may be behind the attacks.

WannaCry, developed in part with hacking techniques that were either stolen or leaked from the U.S. National Security Agency, has infected more than 300,000 computers since Friday, locking up their data and demanding a ransom payment to release it.

Researchers at security firm Proofpoint said the related attack, which installs a currency “miner” that generates digital cash, began infecting machines in late April or early May but had not been previously discovered because it allows computers to operate while creating the digital cash in the background.

Proofpoint executive Ryan Kalember said the authors may have earned more than $1 million, far more than has been generated by the WannaCry attack.

Like WannaCry, the program attacks via a flaw in Microsoft Corp’s <MSFT.O> Windows software. That hole has been patched in newer versions of Windows, though not all companies and individuals have installed the patches.

Digital currencies based on a technology known as blockchain operate by enabling the creation of new currency in exchange for solving complex math problems. Digital “miners” run specially configured computers to solve the problems and generate currency, whose value ultimate fluctuates according to market demand.

Bitcoin is by far the largest such currency, but the new mining program is not aimed at Bitcoin. Rather it targeted a newer digital currency, called Monero, that experts say has been pursued recently by North Korean-linked hackers.

North Korea has attracted attention in the WannaCry case for a number of reasons, including the fact that early versions of the WannaCry code used some programming lines that had previously been spotted in attacks by Lazarus Group, a hacking group associated with North Korea.

Security researchers and U.S. intelligence officials have cautioned that such evidence is not conclusive, and the investigation is in its early stages.

In early April, security firm Kaspersky Lab said that a wing of Lazarus devoted to financial gain had installed software to mine Monero on a server in Europe.

A new campaign to mine the same currency, using the same Windows weakness as WannaCry, could be coincidence, or it could suggest that North Korea was responsible for both the ransomware and the currency mining.

Kalember said he believes the similarities in the European case, WannaCry and the miner were “more than coincidence.”

“It’s a really strong overlap,” he said. “It’s not like you see Monero miners all over the world.”

The North Korean mission to the United Nations could not be reached for comment, while the FBI declined to comment.
