The most dangerous computer virus ever: the story of the Anna Kournikova virus
Anna Kournikova was a computer virus that became widespread in early 2000. The virus was distributed as an email attachment that appeared to be a photo of the Russian tennis player Anna Kournikova. When opened, the attachment would launch a program that would email itself to everyone in the victim’s address book. The email would also contain a message saying “It’s time to update your address book” in an attempt to trick recipients into thinking the email was from a friend.
Anna Kournikova was not actually a dangerous virus, but it did spread quickly and caused a lot of headaches for businesses and individuals who received the email. The virus would clog up email servers and slow down network speeds. In some cases, the virus would even delete important files from a victim’s computer.
While Anna Kournikova was not the most dangerous virus ever, it was certainly one of the most annoying. The virus caused a lot of people to waste time deleting it from their computers and their email inboxes. It also resulted in a lot of lost productivity as people dealing with the virus were not able to work on their normal tasks.
The Anna Kournikova virus was ultimately stopped by a patch that was released by Microsoft. The patch prevented the virus from emailing itself to people in a victim’s address book. However, the virus was so widespread at that point that it continued to cause problems for months after the patch was released.
The Anna Kournikova virus was a reminder of the importance of having a good antivirus program on your computer. It also showed how quickly a virus can spread if it is emailed to a large number of people..Find Out More
The most dangerous computer virus ever: the story of the Code Red virus
The Code Red virus was a computer worm that spread itself by exploiting a buffer overflow vulnerability in the Web server software Microsoft IIS. It was first detected on July 13, 2001, and within nine days had infected more than 359,000 systems running IIS. The virus caused an estimated $2.6 billion in damage.
The Code Red worm was written by two Chinese graduate students, Yi-Sin Chen and Jeffrey Wang. Chen was a student at Zhejiang University in Hangzhou, and Wang was a student at Tsinghua University in Beijing. They named the worm after the Code Red Mountain Dew soft drink.
The worm propagated by infecting Web servers running IIS and then sending itself out to other systems via email. It did not contain any malicious payload, but it did consume significant resources on the systems it infected, slowing them down or crashing them entirely.
The Code Red worm was disastrous not just because of the damage it caused, but also because it shone a light on a serious security flaw in Microsoft IIS. Prior to Code Red, many people believed that Microsoft’s products were “bulletproof” and immune to attack. Code Red proved that was not the case.
Microsoft released a patch for the IIS vulnerability on July 16, 2001, just three days after the worm was first detected. However, many systems were already infected by that time, and others were not properly patched, leading to continued infections.
The Code Red worm was eventually brought under control, but not before causing considerable damage. It is widely considered to be the most damaging computer virus of all time.
