Venus Hostage Activation Key ((link)) – Free

Security researchers examining the VENUS_BETA_ACTIVATION.rar in 2010 discovered a bizarre piece of code. The beta contained a dormant script that, if triggered by a properly formatted "key," would actually overwrite the master boot record of the user's hard drive. The script wasn't malicious—it was meta-commentary. One line read: // You tried to free VENUS. Instead, you become the hostage. // This led many to label the key a piece of "philosophical malware."
