What is Jjyy Ransomware
Jjyy Ransomware is a part of a large STOP/Djvu Ransomware family. It got its name because the original versions of the malware added the
.djvu) file extension and encrypted them with a combination of AES and RSA cryptography to make files inaccessible on the infected Windows computer. Jjyy Ransomware according to its name adds .jjyy extension. This version appeared in July 2022. Once the Jjyy/STOP ransomware completes the encryption procedure, the virus creates a ransom note to _readme.txt file.
