After releasing decryption tools for two variants of CryptXXX ransomware in April and May 2016, Kaspersky Lab is releasing a new decryptor for files that have been locked with the latest version of the malware. This malicious program was capable of infecting thousands of PCs around the world since April 2016, and it was impossible to fully decrypt the files affected by it. But not anymore.
The free RannohDecryptor tool by Kaspersky Lab can decrypt most files with .crypt, .cryp1 and .crypz extensions.
CryptXXX is one of the most actively distributed and dangerous families of ransomware: for a long time criminals used the Angler and Neutrino exploit kits to infect victims with this malware. These two kits were considered among the most effective in terms of successfully infecting targets.
Since April 2016, Kaspersky Lab products have registered attacks by CryptXXX against at least 80,000 users around the world. More than half of them located in only six countries: the US, Russia, Germany, Japan, India and Canada.
