A massive global ransomware outbreak – WanaCrypt0r 2.0

Ransomware is a software designed to prevent the normal function of a computer until a victim pays a ransom. The latest ransomware which brought some of the largest companies to their knees is Ransomware WanaCrypt0r 2.0.

This ransomware has also hit computers across Russia, the Ukraine, Taiwan and China, leading to PCs and data being locked up and held for ransom since last Friday.

Ransomware WanaCrypt0r 2.0 was particularly virulent because it took advantage of hacking tools stolen from the NSA. This malware spreads by exploiting a vulnerability called EternalBlue. They spread using a wave of phishing emails with malicious attachments that infect computers when users click on them. After the attack, the victims were asked to pay up to $300 worth of the cryptocurrency Bitcoin to remove the infection from PCs, otherwise their files remain locked and their computers rendered unusable.

The countries being targeted most by WanaCrpytor 2.0

So far, Avast has recorded more than 75,000 infections in 99 countries. Avast said it will detect all known versions of WanaCrypt0r 2.0. They strongly recommend all Windows users to fully update their system with the latest available patches.

Windows also immediately updated two security tools – the Windows Defender antivirus and Windows Security Essentials but it appears end-users have likely not installed the fixes yet. So if you are reading this, please update your security updates immediately and do not open unknown emails.
