VIRUS - I LOVE YOU (2000)

Travelling via email attachments, "Love Bug" exploited human nature and tricked recipients into opening it by disguising itself as a love letter. The virus stunned security experts by its speed and wide reach. Within hours, the pervasive little computer programme tied up systems around the world. 

The virus which was similar to the earlier Melissa worm, spread via an email with the tantalising subject line, "I Love You." When a recipient opened the attachment, the virus sent copies of itself to his entire address book. It then looked for files with .jpeg, .mp3, .mp2, .css and .hta extensions and overwrote them with itself, changing the extensions to .vbs or .vbe. These files then could not be retrieved in searches. 

The bug affected companies in Taiwan and Hong Kong -- including Dow Jones Newswires and the Asian Wall Street Journal. Companies in Australia had to close down their email systems to keep the virus from spreading (80 per cent of the companies in Australia reportedly got hit). 

The victims also included Parliaments of Britain and Denmark. In Italy, the outbreak hit almost the entire country. In the United States too, the e-mail systems were shut down at several companies.
