The ILOVEYOU virus arrived in email attachments on May 4, 2000. It spread rapidly by sending itself to everyone in the user's address book when opened. Within 24 hours it had infected over 10% of computers worldwide, causing $5.5 billion in damages by overwriting files. The virus was effectively stopped when a software engineer released a repair program just one day later.

1. I LOVE YOU =D By Dan Houck But this cat dose not

2. WHAT HAPPENED ???? The virus arrived in email boxes on May 4, 2000, with the simple subject of "ILOVEYOU" and an attachment "LOVE-LETTER-FOR-YOU.TXT.vbs". Upon opening the attachment, the virus sent a copy of itself to everyone in the user's address list, posing as the user. It also made a number of malicious changes to the user's system.

3. HOW IT WORKED Two aspects of the virus made it effective: It relied on social engineering to entice users to open the attachment and ensure its continued propagation. It exploited the weakness of the email system design that an attached program could be run easily by simply opening the attachment; the underlying mechanism, VBScript had not been exploited to such a degree previously to direct attention to its potential, thus the necessary layers of protection were not in place yet.

4. HOW IT WORKED AGAIN !!!! Its massive spread moved westward as workers arrived at their offices and encountered messages generated by people from the East. Because the virus used mailing lists as its source of targets, the messages often appeared to come from an acquaintance and so might it be considered "safe", providing further incentive to open them. All it took was a few users at each site to access the VBS attachment to generate the thousands and thousands of e-mails that would cripple e-mail systems under their weight, not to mention overwrite thousands of files on workstations and accessible servers.

5. G DANG Spread across the world in one day (traveling from Hong-Kong to Europe to the United States), infecting 10 percent of all computers connected to the Internet and causing about $5.5 billion in damage. The virus overwrote important files such as music, multimedia and more, with a copy of itself. It also sent the virus to everyone on a user's contact list. Because it was written in VBScript, this particular virus only affected computers running the Microsoft Windows O/S. While any computer accessing e-mail could receive an "ILOVEYOU" e-mail, only Microsoft Windows systems would be infected.

6. HOW IT WAS CURED Narinnat Suksawat, a 25-year-old Thai software engineer, was the first person to write software that repaired the damage caused by the worm, releasing it to the public on May 5, 2000, 24 hours after the worm had spread. The virus will then search all drives which are connected to the infected computer and replace files with the extensions *.JPG, *.JPEG, *.VBS, *.VBE, *.JS, *.JSE, *.CSS, *.WSH, *.SCT, *.DOC *.HTA with copies of itself, while appending to the file name a .VBS. extension. The malware will also locate *.MP3 and *.MP2 files, and when found, make the files hidden, copy itself with the same filename and append a .VBS extension.

7. Blah blah blah The alleged authors of the virus, include Irene de Guzman from Manila, Philippines, her brother Onel de Guzman and her boyfriend Reomel Lamores who was briefly held in May 2000 in connection with the virus outbreak
