Mark Washburn, working on an analysis of the Vienna and Cascade viruses with Ralf Burger, develops the first family of polymorphic viruses, the Chameleon family. Chameleon series debuted with the release of 1260. [21] [22] [23] June: The Form computer virus is isolated in Switzerland. It would remain in the wild for almost 20 years and reappear ...

As with most boot viruses, a Form infection is a rare find in modern times. Since the advent of Windows , boot viruses have become increasingly uncommon, including Form. Generally, Form infections are due to the use of floppy disks infected during the original pandemic that have since been taken out of storage.
Sometime prior to August 11, 2003: Other viruses using the RPC exploit exist. [9] August 11, 2003: Original version of the worm appears on the Internet.

Most known for being the first virus targeting Mac computers. Morris: November 2, 1988 Robert Tappan Morris: Widely considered to be the first computer worm. Although created for academic purposes, the negligence of the author unintentionally caused the worm to act as a denial of service attack.
By the time the virus is identified, many names have been used to denote the same virus. Ambiguity in virus naming arises when a newly identified virus is later found to be a variant of an existing one, often resulting in renaming. For example, the second variation of the Sobig worm was initially called "Palyh" but later renamed "Sobig.b ...
Instead, he programmed the worm to copy itself 14% of the time, regardless of the status of infection on the computer. This resulted in a computer potentially being infected multiple times, with each additional infection slowing the machine down to unusability. This had the same effect as a fork bomb, and crashed the computer several times.
The outbreak was estimated to have caused US$5.5–8.7 billion in damages worldwide, [20] [21] [better source needed] and estimated to cost US$10–15 billion to remove the worm. [ 22 ] [ 23 ] Within ten days, over fifty million infections had been reported, [ 24 ] and it is estimated that 10% of Internet-connected computers in the world had ...
