The WannaCry virus encrypts complete operating systems . Only by paying a ransom is it possible to regain control of the system. The ability of the virus to spread autonomously through networks is particularly malicious. Critical infrastructures like hospitals, rail transport operators and telecommunications companies are among the industries affected.
Current findings indicate that the virus infects the following operating systems:
- Windows XP
- Windows 7
- Windows 8
- Windows Server 2003
- Windows Server 2008 – R2
- Windows Server 2012
Case-by-case checks are needed to determine whether Windows 10 systems are also vulnerable.
But how can I protect myself and what do I need? First up you need to install the latest updates! Okay, fine, but what about viruses that haven’t been released yet? Over 300,000 new viruses, trojans and worms swarm onto the market every day. Obviously the anti-virus vendors are unable to detect them all. Many of them don’t even want to be found, and remain tucked away in their host systems, just waiting to release chaos. Zero day exploits send their regards. That’s what the WannaCry virus was all about. But how did it happen? Here’s a timeline:
