WannaCry (or WannaCrypt) is a ransomware program targeting the Microsoft Windows operating system. On Friday, 12 May 2017, a large cyber-attack was launched using it, infecting more than 230,000 computers in 150 countries, demanding ransom payments in the cryptocurrency bitcoin in 28 languages.
WannaCry exploits a vulnerability identified long ago by the NSA, and leaked last month by a group called the Shadow Brokers has caused computers across the world to be infected at a rapid rate. It’s important to note the computers that were vulnerable to this attack fell into two main groups: those running Windows XP and those running Windows 10 but weren’t patched. Patching systems is important, but rarely does due to the time and effort required to ensure workstations are running the latest release of Windows.
A third, potentially dangerous source is users clicking on links and opening emails, attachments and USB drives from unknown sources.
There will be many more viruses and malware in the coming weeks. ComputeZero specialize in information security and encourage customers to:
- Patch systems regularly. All our customer’s workstations and servers are patched automatically by us, using our endpoint monitoring solution.
- Ensure all workstations run commercial anti-virus software like Webroot.
- Educate and encourage staff, users and family members to be careful when opening emails, attachments and USB disks from unknown sources or people.
