IT security provider Kaspersky Lab has issued a security alert following the detection of a particularly malicious piece of “ransomware.” Kaspersky researchers were the first to detect and issue warnings that a new, stronger version of the Gpcode virus was on the loose. Even though it doesn’t appear to have spread widely — to date at least — the new Gpcode variant poses a particularly nasty threat. If downloaded, the virus — Virus.Win32.Gpcode.ak — employs RSA 1024-bit encryption to lock users out of just about every common data file format found on their PCs.
