Happy99 (also termed Ska or I-Worm)[4] is a computer worm for Microsoft Windows. It first appeared in mid-January 1999, spreading through email and usenet. The worm installs itself and runs in the background of a victim's machine, without their knowledge. It is generally considered the first virus to propagate by email, and has served as a template for the creation of other self-propagating viruses. Happy99 has spread on multiple continents, including North America, Europe, and Asia.

Significance

Happy99 was described by Paul Oldfield as "the first virus to spread rapidly by email".[5] In the Computer Security Handbook, Happy99 is referred to as "the first modern worm".[6] Happy99 also served as a template for the creation of ExploreZip, another self-spreading virus.[7]

Spread

The worm first appeared on 20 January 1999.[8] Media reports of the worm started coming in from the United States and Europe, in addition to numerous complaints on newsgroups from users that had become infected with the worm.[9] Asia Pulse reported 74 cases of the virus from Japan in February, and 181 cases were reported in March—a monthly record at the time.[10][11] On 3 March 1999, a Tokyo job company accidentally sent 4000 copies of the virus to 30 universities in Japan.[12]

Dan Schrader of Trend Micro said that Happy99 was the single most commonly reported virus in their system for the month of March.[13] A virus bulletin published in February 2000 reported that Happy99 caused reports of file-infecting malware to reach over 16% in April 1999.[14] Sophos listed Happy99 among the top ten viruses reported in the year of 1999.[15] Eric Chien, head of research at Symantec, reported that the worm was the second most reported virus in Europe for 2000.[16] Marius Van Oers, a researcher for Network Associates, referred to Happy99 as "a global problem", saying that it was one of the most commonly reported viruses in 1999.[17] When virus researcher Craig Schmugar posted a fix for the virus on his website, a million people downloaded it.[18]

Technical details

The worm spreads through email attachments and usenet.[19][20][21] When executed, animated fireworks and a "Happy New Year" message display.[19][22] The worm modifies Winsock, a Windows communication library, to allow itself to spread.[19] The worm then attaches itself automatically to all subsequent emails and newsgroup posts sent by a user.[23] The worm modifies a registry key to automatically start itself when the computer is rebooted. In some cases, the program may cause several error messages to appear.[24]

The worm was written by a French virus writer known as "Spanska". Other than propagating itself, the worm does no further damage to an infected computer.[25][26] The worm typically uses port 25 to spread, but uses port 119 if port 25 is not available.[24] The executable of the worm is 10,000 bytes in size; a list of spammed newsgroups and mail addresses is stored on the infected hard drive.[22][27] The worm spreads only if the Winsock library is not set to read-only.
