1260, or V2PX[1][2], was a computer virus written in 1989 by Mark Washburn that used a form of polymorphic encryption. Derived from Ralph Burger's publication of the disassembled Vienna virus source code, the 1260 altered its signature by randomizing and obfuscating its decryption algorithm in an effort to keep its signature length short and variable. Both the 1260 and Vienna infect .COM files in the current or PATH directories upon execution. Signature alteration of an authenticated executable file is detected by most modern computer operating systems.[3][4][5]
