What you need to know about the massive hack that hit the British health-care system and elsewhere

2017.05.13 06

It was first reported in England — hackers gained access to the National Health Service computers, effectively shuttering the entire system. Patients were told to stay home; doctors and nurses were unable to access email or medical records and had to take notes by hand. The hackers demanded a ransom, to be paid in bitcoin.

By Friday afternoon, though, it was clear that this was not a limited attack. Businesses in at least 11 other countries reported similar cyberattacks. Many were paralyzed.

According to Britain’s Independent newspaper, these attacks may stretch around the globe, from Portugal to Turkey, Indonesia, Vietnam, Japan, Germany and Russia. It “is much larger than just the NHS,” Travis Farral, director of security strategy for cybersecurity firm Anomali Labs, told the Independent. “It appears to be a giant campaign that has hit Spain and Russia the hardest.”

If you run a business, back up every computer in your office and have a plan for what to do if your system goes down for a while. Be smart about setting up your network, so that most users don’t have complete access to the system. This makes it harder for a ransomware attack to infect everything. And make sure your users are educated about the common kinds of attacks.
