A new ransomware family has been discovered, which targets specifically Linux-based systems using a range of encryption methods. GwisinLocker is the malware responsible for the attack.


The GwisinLocker ransomware is one of the latest types of ransomware targeting South Korean companies in industries and pharmaceuticals.

In addition to being an entirely new malware variant, it is notable for the fact that it was produced by a threat actor that had been little known previously.
