How to Protect from WannaCry Ransomware
On 12th May, there was a major outbreak of ransomware called WannaCry (or WannaCrypt, WanaCrypt0r 2.0, Wanna Decryptor). It has infected 230,000 computers in 150 countries within a short span of time.
Europol has described as unprecedented in scale, never heard or known in the history.
Once infected, ransomware locks all the files on computer and demands a ransom payment of $300 USD on an average in form of Bitcoins.
How WannaCry is Spreading?
It has targeted large businesses mainly instead of individuals and spread through phishing emails and ExternalBlue exploit in Windows OS.
Security patch for this exploit was release two months ago (14 March 2017) but companies didn't patch their systems on time.
Each delay or click on "update later" has helped increase in the number of ransomware attack.
The reason why this particular campaign became so extensive is because it exploits a vulnerability in Windows SMBv1 and SMBv2 to move laterally within networks and infect other computers.
Bad news is that the attack is ongoing and every Windows PC is vulnerable to it.
To protect yourself, first step is to patch computer system.
