This is a timeline of noteworthy computer viruses, worms and trojans.

1970-1979 Edit

1971 Edit

  • The Creeper virus, an experimental self-replicating program, is written by Bob Thomas at BBN. Creeper infected DEC PDP-10 computers running the TENEX operating system. Creeper gained access via the ARPANET and copied itself to the remote system where the message, "I'm the creeper, catch me if you can!" was displayed. The Reaper program was later created to delete Creeper.

1974 Edit

  • The Wabbit virus, more a fork bomb than a virus, is written. The Wabbit virus made multiplies copies of itself on a single computer (and was named "Wabbit" for the speed at which it did so) until clogged the system with copies of itself, reducing system performance, before finally reaching a threshold and crashing the computer.

1974/1975 Edit

  • ANIMAL is written by John Walker for the UNIVAC 1108.[1] Animal asked a number of questions to the user in an attempt to guess the type of animal that the user was thinking of, while the related program PERVADE would create a copy of itself and ANIMAL in every directory to which the current user had access. It spread across the multi-user UNIVACs when users with overlapping permissions discovered the game, and to other computers when tapes were shared. The program was carefully written to avoid damage to existing file or directory structure, and to not copy itself if permissions did not exist or if damage could result. Its spread was therefore halted by an OS upgrade which changed the format of the file status tables that PERVADE used for safe copying. Though non-malicious, "Pervading Animal" represents the first trojan "in the wild".[2]

1980-1989 Edit

1980 Edit

  • Jürgen Kraus wrote his master thesis "Selbstreproduktion bei Programmen" (self-reproduction of programs).[3]

1981 Edit

  • A program called Elk Cloner, written for Apple II systems and created by Richard Skrenta. Apple II was seen as particularly vulnerable due to the storage of its operating system on floppy disk. Elk Cloner's design combined with public ignorance about what malware was and how to protect against it led to Elk Cloner being responsible for the first large-scale computer virus outbreak in history.

1983 Edit

  • The term 'virus' is coined by Frederick Cohen in describing self-replicating computer programs. In 1984 Cohen uses the phrase "computer virus" – as suggested by his teacher Leonard Adleman – to describe the operation of such programs in terms of "infection". He defines a 'virus' as "a program that can 'infect' other programs by modifying them to include a possibly evolved copy of itself."
  • November 10, 1983, at Lehigh University, Cohen demonstrates a virus-like program on a vax|VAX11/750 system. The program was able to install itself to, or infect, other system objects.

1984 Edit

  • Ken Thompson publishes "Reflections on Trusting Trust"[4], a theoretical paper which describes how a virus can be inserted into a program's object code, when the virus itself cannot be found in the source code.

1986 Edit

  • January: The Brain boot sector virus (aka Pakistani flu) is released. Brain is considered the first IBM PC compatible virus, and the program responsible for the first IBM PC compatible virus epidemic. The virus is also known as Lahore, Pakistani, Pakistani Brain, as it was created in Lahore, Pakistan by 19 year old Pakistani programmer, Basit Farooq Alvi, and his brother, Amjad Farooq Alvi.
  • December 1986: Ralf Burger presented the Virdem model of programs at a meeting of the underground Chaos Computer Club in Germany. The Virdem model represented the first programs that could replicate themselves via addition of their code to executable DOS files in COM format.

1987 Edit

  • Appearance of the Vienna virus, which was subsequently neutralized—the first time this had happened on the IBM platform.[5]
  • Appearance of Lehigh virus, boot sector viruses such as Yale from USA, Stoned from New Zealand, Ping Pong from Italy, and appearance of first self-encrypting file virus, Cascade. Lehigh was stopped on campus before it spread to the wild, and has never been found elsewhere as a result. A subsequent infection of Cascade in the offices of IBM Belgium led to IBM responding with its own antivirus product development. Prior to this, antivirus solutions developed at IBM were intended for staff use only.
  • October: The Jerusalem virus, part of the (at that time unknown) Suriv family, is detected in the city of Jerusalem. Jerusalem destroys all executable files on infected machines upon every occurrence of Friday the 13th (except Friday 13 November 1987 making its first trigger date May 13, 1988). Jerusalem caused a worldwide epidemic in 1988.
  • November: The SCA virus, a boot sector virus for Amigas appears, immediately creating a pandemic virus-writer storm. A short time later, SCA releases another, considerably more destructive virus, the Byte Bandit.
  • December: Christmas Tree EXEC was the first widely disruptive replicating network program, which paralysed several international computer networks in December 1987.

1988 Edit

  • June: The Festering Hate Apple ProDOS virus spreads from underground pirate BBS systems and starts infecting mainstream networks.
  • November 2: The Morris worm, created by Robert Tappan Morris, infects DEC VAX and Sun machines running BSD UNIX connected to the Internet, and becomes the first worm to spread extensively "in the wild", and one of the first well-known programs exploiting buffer overrun vulnerabilities.

1989 Edit

1990-1999 Edit

1990 Edit

1992 Edit

  • Michelangelo was expected to create a digital apocalypse on March 6, with millions of computers having their information wiped according to mass media hysteria surrounding the virus. Later assessments of the damage showed the aftermath to be minimal.

1993 Edit

2000 and later Edit

2000 Edit

  • May: The ILOVEYOU worm appears. As of 2004 this was the most costly virus to businesses, causing upwards of 5.5 to 10 billion dollars in damage. The backdoor trojan to the worm, Barok, was created by Filipino programmer Onel de Guzman; it is not known who created the attack vector or who (inadvertently?) unleashed it; de Guzman himself denies being behind the outbreak although he suggests he may have been duped by someone using his own Barok code as a payload.

2001 Edit
