WannaCry Ransomware: How to protect yourself

  1. If you use Windows, install the patch that Microsoft has released to block the specific exploit that the WannaCry ransomware is using. You can find instructions on this page in the Microsoft Knowledge Base. You can also directly download the patches for your OS from the Microsoft Update Catalog.
  2. If you are using an unsupported version of Windows like Windows XP, Windows 2008 or Server 2003, you can get the patches for your unsupported OS from the Update Catalog. We do recommend that you update to a supported version of Windows as soon as possible.
  3. Update your Antivirus software definitions. Most AV vendors have now added detection capability to block WannaCry.
  4. If you don’t have anti-virus software enabled on your Windows machine, we recommend you enable Windows Defender which is free.
  5. Backup regularly and make sure you have offline backups. That way, if you are infected with ransomware, it can’t encrypt your backups.
  6. For further reading, Microsoft has released customer guidance for the WannaCry attacks and Troy Hunt has done an excellent detailed writeup on the WannaCry ransomware.

Get the word out

The second wave of attacks appears to have just started within the past few hours. This is going to be a rough week for Windows users. We recommend you get the word out by sharing this post to help keep friends and family secure.

 

Location of Attacks (According to Kasper-sky Lab)

Several large organizations reported an infection simultaneously. Among them were several British hospitals that had to suspend their operations. According to data released by third parties, WannaCry has infected more than 200,000 computers. The sheer number of infections is a big part of the reason it has drawn so much attention.

The largest number of attacks occurred in Russia, but Ukraine, India, and Taiwan have suffered much damage from WannaCry as well. In just the first day of the attack, we found WannaCry in 74 countries.
