Appearance of Lehigh virus (discovered at its namesake university), [20] boot sector viruses such as Yale from the US, Stoned from New Zealand, Ping Pong from Italy, and appearance of the first self-encrypting file virus, Cascade. Lehigh was stopped on campus before it spread to the "wild" (to computers beyond the university), and as a result ...
The first known polymorphic virus was written by Mark Washburn. The virus, called 1260, was written in 1990. A better-known polymorphic virus was created in 1992 by the hacker Dark Avenger as a means of avoiding pattern recognition from antivirus software. A common and very virulent polymorphic virus is the file infecter Virut.

Sality is a family of polymorphic file infectors, which target Windows executable files with the extensions .EXE or .SCR. [1] Sality utilizes polymorphic and entry-point obscuring (EPO) techniques to infect files using the following methods: not changing the entry point address of the host, and replacing the original host code at the entry point of the executable with a variable stub to ...
1260, or V2PX, [1] [2] was a polymorphic computer virus written in 1989 by Mark Washburn. Derived from Ralf Burger's publication of the disassembled Vienna Virus source code, the 1260 added a cipher and varied its signature by randomizing its decryption algorithm. Both the 1260 and Vienna infect .COM files in the current or PATH directories ...

Polymorphic attacks don't have a single detectable signature, making them very difficult for signature-based IDS, and even some anomaly-based IDS, to detect. [ 1 ] [ 4 ] Shikata ga nai ("it cannot be helped") is a popular polymorphic encoder in the Metasploit framework used to convert malicious shellcode into difficult-to-detect polymorphic ...
