Security researchers say that the Cryptolocker ransomware, or a copycat variant, has become more pernicious because it can now spread automatically to USB sticks.
A new variant of the file-encrypting ransomware known as Cryptolocker has begun spreading using a dangerous new feature: self propagation through USB drives, according to multiple security firms.
Antivirus firms Trend Micro and ESET both found evidence of the new version of Cryptolocker spreading on the Internet. The malicious software is somewhat different than the original Cryptolocker, including functionality which creates a copy of itself on removable media, suggesting that the malware could be a copycat.
