One of the more common and destructive computer crimes to emerge over the past few years involves ransomware — malicious code that quietly scrambles all of the infected user’s documents and files with very strong encryption.

Recently, however, anonymous criminals have added insult to injury, releasing a keylogger that publishes stolen information for all the world to see at online notepad sharing sites such as pastebin.com.
