Massive international cyber attack hits computers across Europe, Asia and Russia

London: A huge cyber attack struck computers across Europe and Asia on Friday, crippling health services and closing emergency rooms in Britain.

The attack involved ransomware, a kind of malware that encrypts data and locks out the user. According to security experts, it exploited a vulnerability that was discovered and developed by the National Security Agency (NSA) in the US.

The hacking tool was leaked by a group calling itself the Shadow Brokers, which has been dumping stolen NSA hacking tools online since the beginning of last year. Microsoft rolled out a patch for the vulnerability last March, but hackers took advantage of the fact that vulnerable targets – particularly hospitals – had yet to update their systems.

The malware was circulated by email; targets were sent an encrypted, compressed file that, once loaded, allowed the ransomware to infiltrate its targets.

Employees of Britain’s National Health Service (NHS) were warned about the ransomware threat early on Friday, but by then it was too late.

As the disruptions rippled through hospitals, doctors’ offices and ambulance services across Britain, the NHS declared the attack a “major incident” and patients were asked to only seek assistance for serious medical emergencies.

Hospitals and telecommunications companies across Europe, Russia and Asia were affected, according to MalwareHunterTeam, a security firm that tracks ransomware attacks.

Spain’s Telefonica and Russia’s MegaFon were among the telecommunications targets.

Attacks were being reported in Britain and 11 other countries, including Turkey, Vietnam, the Philippines, Japan, with the majority of affected computers in Russia. The computers all appeared to be hit with the same ransomware, and similar ransom messages demanding about $US300 to unlock their data.

The attack on the NHS seemed perhaps the most audacious of the attacks, because it had life-or-death implications for hospitals and ambulance services.

Tom Donnelly, a spokesman for NHS Digital, the arm of the health service that handles cybersecurity, said in a phone interview that 16 organisations, including “hospitals and other kinds of clinician services,” had been hit. Officials later updated that number to at least 25.

Hospitals and doctors’ surgeries were forced to turn away patients and cancel appointments as the attack crippled computer systems.

The Spanish government said a large number of companies, including telecommunications giant Telefonica, had been infected. Portugal Telecom was also hit but no services were impacted, a spokeswoman for the company said.

“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.

In Spain, some big firms took pre-emptive steps to thwart ransomware attacks following a warning from the National Cryptology Centre of “a massive ransomware attack.” It said hackers used a version of a virus known as WannaCry that targets Microsoft Corp’s widely used Windows operating system.

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.
