- Timeline of notable computer viruses and worms
This is a
timelineof noteworthy computer viruses and worms.
* Creeper virus was detected on
ARPANETinfecting the Tenex operating system. Creeper gained access independently through a modem and copied itself to the remote system where the message, 'I'M THE CREEPER : CATCH ME IF YOU CAN.' was displayed. The Reaper program, itself being a virus, was created to delete Creeper. The creators of both programs are unknown.
Rabbit virusappears infecting other machines via multiplication. Named for the speed at which it clogged the system with copies of itself, reducing system performance, before reaching a threshold and crashing.
* ANIMAL was a popular game written for the
UNIVAC 1108which asked a number of questions to the user in an attempt to guess the type of animal that the user was thinking of. When run, the related program PERVADE would also 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 (and fairly entertaining) in nature, "Pervading Animal" represents the first Trojan "in the wild". [http://www.fourmilab.ch/documents/univac/animal.html The Animal Episode ] ]
* Jürgen Kraus wrote master thesis Selbstreproduktion bei Programmen (Self-reproduction of programs).
* 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 malwarewas and how to protect against it led to Elk Cloner being responsible for the first large-scale computer virus outbreak in history.
* 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 VAX11/750 system. The program was able to install itself to, or infect, other system objects.
* January: The Brain
boot sectorvirus (aka Pakistani flu) is released. Brain is considered the first IBM PC compatiblevirus, 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 Clubin Germany. The Virdem model represented the first programs that could replicate themselves via addition of their code to executable DOS files in COM format.
* Appearance of the Vienna virus, which was subsequently neutralized--the first time this had happened on the IBM platform. [ [http://www.viruslist.com/en/viruses/encyclopedia?chapter=153311150 Kaspersky Lab viruslist] ]
* 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.
Christmas Tree EXECwas the first widely disruptive replicating network program, which paralysed several international computer networks in December 1987.
* June: The
Festering Hate Apple ProDOSvirus spreads from underground pirate BBS systems and starts infecting mainstream networks.
November 2: The Morris worm, created by Robert Tappan Morris, infects DEC VAXand Sun machines running BSD UNIXconnected to the Internet, and becomes the first worm to spread extensively "in the wild", and one of the first well-known programs exploiting buffer overrunvulnerabilities.
October 1989: Ghostball, the first multipartite virus, is discovered by Friðrik Skúlason
* Mark Washburn working on an analysis of the Vienna and Cascade viruses with Ralf Burger develops the first family of polymorphic virus: the Chameleon family. Chameleon series debuted with the release of 1260.
* 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.
* The "Concept virus" the first Macro virus is created This virus did a lot of damage.
* "Ply" - DOS 16-bit based complicated polymorphic virus appeared with built-in permutation engine.
June 2: The first version of the CIH virus appears.
March 26: The Melissa worm is released, targeting Microsoft Word and Outlook-based systems, and creating considerable network traffic.
June 6: The ExploreZipworm, which destroys Microsoft Officedocuments, is first detected.
Happy1999worm invisibly attached itself to emails. Displayed fireworks to hide changes being made and wished you a happy new year. Modified system files related to Outlook Expressand Internet Exploreron Windows 95and Windows 98.
2000 and later
* May: The
VBS/Loveletter('ILOVEYOU') worm appeared. As of 2004this is 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.
* Zmist - a fully metamorphic, code integrating virus.
