ESET security researchers have created and released a free decryption tool to combat Crysis ransomware based on the malware's master decryptor keys that were made public earlier this month.
ESET's decryption tool, which joins one developed by Kaspersky Labs, uses information released on Pastebin and first reported by Bleeping Computer.
The security firm has detected variants of Crysis appearing in 123 countries since it was released in May 2016 with people in France, Spain and Brazil being victimized most frequently. Cybercriminals use a variety of methods to spread the malware, including spam and infected ads found on social networks.
Bleeping Computer founder Lawrence Abrams believes the decryptor master keys posted on Pastebin are possibly from the malware's creator because they contain the C header files.
