In the wake of a worldwide cyber-attack using WANNACRY ransomware that encrypts Windows systems, cyber security experts say Zimbabwe might see a larger impact on safety and more computers infected when offices open after the weekend break.
As of this writing we have not heard of any organisation being affected by the ransomware.
How does it work?
WannaCry is a form of “ransomware” that locks up the files on your computer and encrypts them in a way that you cannot access them anymore.
The massive global ransomware campaign launched by unknown hackers using NSA tools has affected close to 150 countries.
Ransomware is a program that gets into your computer, either by clicking on the wrong thing or downloading the wrong thing, and then it holds something you need to ransom.
In the case of WannaCry, the malware was circulated by email and it targets were sent an encrypted, compressed file that, once loaded, allowed the ransomware to infiltrate its targets. The program encrypts your files and demands payment in bitcoin in order to regain access.
This ransomware spreads by using a vulnerability in implementations of Server Message Block (SMB) in Windows operating software such as XP, Windows 8 and Windows Server 2003.
