Are you ready for a second wave of WannaCry ransomware?

WannaCry is a name that made many cry in frustration this weekend, and the danger is still not over.

According to Europol director Rob Wainwright, over 200,000 victims in at least 150 countries have had their files encrypted by the WannaCry (aka Wanna Decryptor) ransomware/worm.

The number would have been even higher, but a security researcher reverse-engineered a sample of the malware, found in its code a non-existent, hard-coded domain (iuqerfsodp9ifjaposdfjhgosurijfaewrwergwea.com) that each installed malware instance tries to contact, and registered it. With this move he inadvertently stopped the situation from becoming even worse, as the malware does not spring into action if it manages to contact the domain.
