Kaspersky Lab has detected curious behavior in a new threat from the TeslaCrypt ransomware encryptor family. In version 2.0 of the Trojan notorious for infecting computer gamers, it displays an HTML page in the web browser which is an exact copy of CryptoWall 3.0, another ransomware program.
Perhaps the criminals are doing this as a statement of intent: so far, many files encrypted by CryptoWall could not be decrypted, which is not the case with many past cases of TeslaCrypt infection. After a successful infection, the malicious program demands a $500 ransom for the decryption key; if the victim delays, the ransom doubles.
Early samples of TeslaCrypt were detected in February 2015 and the new ransomware Trojan gained immediate notoriety as a menace to computer gamers. Amongst other types of target files, it tries to infect typical gaming files: game saves, user profiles, recoded replays etc. That said, TeslaCrypt does not encrypt files that are larger than 268 MB.
