Massive cyber-attack hits Europe with widespread ransom demands

Social media sharing

A new wave of powerful cyber-attacks hit Europe and beyond on Tuesday in a possible reprise of a widespread ransomware assault in May. Affected were a Russian oil giant, a Danish shipping and energy conglomerate, and Ukrainian government ministries, which were brought to a standstill in a wave of ransom demands. The virus even downed systems at the site of the former Chernobyl nuclear power plant, forcing scientists to monitor radiation levels there manually.

Cyber-attacks also spread as far as India and the United States, where the Merck pharmaceutical giant reported on Twitter that “our company’s computer network was compromised today as part of global hack.” The New Jersey-based company said it was investigating the attack.

Cyber researchers say that the virus, which was linked to malware called Petrwrap or Petya, used an “exploit” developed by the National Security Agency that was later leaked onto the Internet by hackers. It is the second massive attack in the past two months to turn powerful U.S. exploits against the IT infrastructure that supports national governments and corporations.

The onslaught of ransomware attacks may be the “new normal,” said Mark Graff, the chief executive of Tellagraff, a cyber-security company.

“The emergence of Petya and WannaCry really points out the need for a response plan and a policy on what companies are going to do about ransomware,” he said. WannaCry was the ransomware used in the May attack. “You won’t want to make that decision at a time of panic, in a cloud of emotion.”

The attack mainly targeted Eastern Europe but also hit companies in Spain, Denmark, Norway and Britain. Victims included the British advertising and marketing multinational WPP and a shipping company, APM Terminals, based at the port of Rotterdam.

But the damage was worst in Ukraine.

Researchers at Kaspersky Lab’s Global Research and Analysis Team, in Russia, estimated that 60 percent of infected computers were in Ukraine and 30 percent in Russia.

The hacks targeted government ministries, banks, utilities and other important infrastructure and companies nationwide, demanding ransoms from government employees in the crypto currency bitcoin.

The hacks’ scale and the use of ransomware recalled the massive May cyber-attack in which hackers possibly linked to North Korea disabled computers in more than 150 nations using a flaw that was once incorporated into the National Security Agency’s surveillance tool kit.

Cyber researchers have tied the vulnerability exploited by Petya to the one used by WannaCry — a weakness discovered by the NSA years ago that the agency turned into a hacking tool dubbed EternalBlue. Petya, like WannaCry, is a worm that spreads quickly to vulnerable systems, said Bill Wright, senior policy counsel for Symantec, the world’s largest cyber security firm. But that makes it difficult to control — or to aim at anyone in particular, he said.

“Once you unleash something that propagates in this manner, it’s impossible to control,” he said.

He expressed puzzlement about why firms and governments are still being hit. Microsoft in March made available a patch for the Windows flaw that EternalBlue exploited.

“If you were running an updated operating system and had the latest patch, you would be protected,” Wright said.

The ransomware hit Europe in the early afternoon. Ground zero was Ukraine. Breaches were reported at computers governing the municipal energy company and airport in the capital, Kiev, the state telecommunications company Ukrtelecom, the Ukrainian postal service and the State Savings Bank of Ukraine.

Grocery store checkout machines broke down, ATMs demanded ransom payments, and the turnstile system in the Kiev metro reportedly stopped working.

The mayhem reached high into the government. Ukrainian Deputy Prime Minister Pavlo Rozenko on Tuesday tweeted a picture of a computer screen warning in English that “one of your disks contains errors,” then adding in all capital letters: “DO NOT TURN OFF YOUR PC! IF YOU ABORT THIS PROCESS, YOU COULD DESTROY ALL YOUR DATA!”

“Ta-Dam!” he wrote. “It seems the computers at the Cabinet of Ministers of Ukraine have been ‘knocked out.’ The network is down.” His spokeswoman published a photograph showing demands for a ransom in bitcoin to release data encrypted by the virus.

Suspicions in Ukraine quickly fell on Russia, which annexed Crimea in 2014 and has been blamed for several large-scale cyber-attacks on Ukraine’s power infrastructure. But no proof of the attack was presented, and Russian companies, like the oil giant Rosneft, also complained of being hit by a “powerful hacking attack.” Photographs leaked to the news media from a Rosneft-owned regional oil company showed computers displaying ransomware demands similar to those in Ukraine.

The virus also brought havoc to Western Europe. A.P. Moller – Maersk Group, a Danish transport and energy conglomerate, announced that “Maersk IT systems are down across multiple sites and business units due to a cyber-attack.”

The company was trying to determine exactly how broad the attack was. “We are assessing the situation, and of course the safety of our employees and our operations alongside our customers’ business — these are our top priorities,” Maersk spokeswoman Concepción Boo Arias said
