The most dangerous computer virus ever: the story of the Storm Worm
The Storm Worm is a computer virus that was first discovered in 2006. It is considered to be one of the most dangerous virus ever created because of its ability to spread quickly and infect a large number of computers. The Storm Worm is a type of malware known as a Trojan horse. This means that it is a program that appears to be something innocent or harmless but is actually malicious. The Storm Worm is spread through email attachments or by visiting infected websites. Once a computer is infected with the Storm Worm, it will start to send out emails to all of the addresses in its address book. These emails contain a link to an infected website or an attachment that will infect the computer if it is opened. The Storm Worm is also able to spread itself by taking advantage of security flaws in other programs. This allows it to infect computers that are not running the Windows operating system. The Storm Worm is believed to be responsible for taking down several large websites, including eBay, Yahoo, and PayPal. The Storm Worm is a very difficult virus to remove from an infected computer. It is important to have a good antivirus program installed on your computer to protect it from this and other malware..Click Here
The most dangerous computer virus ever: the story of the Nimda virus
It was the autumn of 2001, and the world was still reeling from the 9/11 attacks. Then, as if the world needed any more bad news, a new computer virus began spreading like wildfire across the internet. This virus, known as Nimda, would go on to become one of the most destructive and costly computer viruses of all time.
Nimda (pronounced “nim-uh-duh”) was a so-called “worm” virus, meaning that it could spread itself automatically and quickly without any help from users. Once a computer was infected with Nimda, the virus would spread itself by scanning for other vulnerable computers on the same network and then copying itself to those computers. The virus would also spread itself by email, sending itself out to all the addresses in the infected computer’s address book.
But Nimda didn’t just spread quickly, it was also unusually destructive. The virus would infect not just individual files but entire systems, rendering them unusable. And it didn’t just affect PCs – Nimda was also one of the first viruses to successfully infect Macs and Unix systems.
Nimda was first spotted on September 18th, 2001, and within 24 hours it had spread to tens of thousands of computers around the world. By the end of the week, it is estimated that Nimda had infected over five million computers in over 150 countries. The virus caused an estimated $626 million in damage, making it one of the most costly computer viruses of all time.
So how did Nimda manage to cause so much damage?
Part of the reason was its unusually high infection rate. Another part of the reason was its destructiveness. But Nimda was also notable for its ability to spread itself in multiple ways. In addition to spreading itself by email and network, the virus could also spread itself by infecting web pages.
If a user visited an infected web page, their computer would become infected with Nimda – even if they didn’t click on anything or download anything. This was possible because Nimda would modify web pages to include a piece of code that would automatically infect any computer that viewed the page.
This meant that, in addition to spreading itself through email and networks, Nimda could also spread itself through the millions of internet users who surf the web every day.
The Nimda virus was finally defeated by the release of a “patch” – a piece of software that fixed the security hole that Nimda exploited. But by then, the damage had been done. Nimda remains one of the most destructive and costly computer viruses of all time.
