33 Virus (con’t)Jerusalem, is unleashed. Activated every Friday the 13th, the virus affects both .EXE and .COM files and deletes any programs run on that day.Symantec launches Norton AntiVirus, one of the first anti-virus programs developed by a large company.Tequila is the first widespread polymorphic virus found in the wild. Polymorphic viruses make detection difficult for virus scanners by changing their appearance with each new infection.viruses are in existence, an increase of 420% from December of 1990.
34 Virus (con’t)The Melissa virus, W97M/Melissa, executes a macro in a document attached to an , which forwards the document to 50 people in the user's Outlook address book. The virus also infects other Word documents and subsequently mails them out as attachments. Melissa spread faster than any other previous virus.The Love Bug, also known as the ILOVEYOU virus, sends itself out via Outlook, much like Melissa. The virus comes as a VBS attachment and deletes files, including MP3, MP2, and JPG. It also sends usernames and passwords to the virus' author. W97M.Resume.A, a new variation of the Melissa virus, is determined to be in the wild. The "resume" virus acts much like Melissa, using a Word macro to infect Outlook and spread itself.
35 Virus (con’t) 2001 The Anna Kournikova virus, also known as VBS/SST. It spreads by sending copies of itself to the entire address book in Microsoft Outlook.It is believed that this virus was created with a so-called virus creation kit, a program which can enable even a novice programmer to create these malicious programs.The Code Red I and II worms attacked computer networks in July and August.According to Computer Economics they affected over 700,000 computers and caused upwards of 2 billion in damages.A worm spreads through external and (then) internal computer networks, as opposed to a virus which infects computers via and certain websites.Code Red took advantage of a vulnerability in Microsoft's Windows 2000 and Windows NT server software.Microsoft developed a patch to protect networks against the worm, and admits that they too were attacked. Other major companies affected include AT&T, and the AP.
36 Virus (con’t)Trojan.Xombe, Randex, Bizex, Witty, MP3Concept, Sasser, Mac OS X, W64.Rugrat.3344, Symb/Cabir-A, JS/Scob-A, WCE/Duts-A, W32/Amus-A,social engineering taking the lead in propagation techniques. Trojan.Xombe was sent out to a wide audience.It posed as a message from Microsoft Windows Update asking you to run the attached revision to XP Service Pack 1.In February it was demonstrated that virus writers were starting to ply their craft for money. A German magazine managed to buy a list of infected IP addresses from a distributor of the virus Randex. These IP addresses were for sale to spammers who could use the infected machines as mail zombies.In April saw the Sasser worm which is the first to effectively use the LSASS Windows vulnerability; a vulnerability that allowed the worm to spread via an open FTP port instead of throughIn June Symb/Cabir-A appeared to infect Nokia Series 60 mobile phones. The worm is designed to spread to nearby Bluetooth-enabled devices.
37 Virus (con’t) 2005 - Bropia, Troj/BankAsh, Commwarrior, Chod In 2005 the end of January saw the Bropia Worm which targets MSN Messenger for spreading.The 9th of February then saw Troj/BankAsh, the first Trojan to attack the new (still in beta) Microsoft AntiSpyware product.This Trojan also was reported to go after various British on-line banking services.The start of March saw distribution of another mobile phone worm: Commwarrior, which spread via MMS messaging.The end of March/start of April saw variants of Chod appear. This is a sophisticated worm that spreads via and the MSN Messaging client.
