The most dangerous computer virus ever: the story of the Nimda virus
In the fall of 2001, a new computer virus began making its way around the internet. Named “Nimda” after the admin password in the Hebrew language, this virus was unlike any other that had come before it.
Unlike other viruses, which typically rely on people accidentally executing a malicious file, Nimda could spread itself automatically by taking advantage of vulnerable systems. It could spread via email attachments, open network shares, and even by infecting websites that people visited. Once a system was infected, Nimda would scan for other systems to infect, using a variety of methods.
This made Nimda extraordinarily dangerous, as it could quickly spread across an entire network, infecting hundreds or even thousands of systems in a matter of hours. And because it used a variety of methods to spread, it was very difficult to stop.
Nimda was first noticed on September 18, 2001, just a week after the terrorist attacks on the World Trade Center and the Pentagon. At first, it was thought to be a hoax, or perhaps a new variant of the Code Red virus, which had caused widespread damage just a few weeks earlier. But it quickly became clear that Nimda was something different.
Within 24 hours, Nimda had spread to tens of thousands of systems around the world. And by the end of the week, it was estimated to have infected over a million computers.
Fortunately, Nimda was not destructive like some other viruses. It did not delete files or damage systems. However, it could clog up networks and make computers sluggish. And because it spread so quickly, it caused a great deal of disruption.
At the time, Nimda was the fastest-spreading virus ever seen. It was eventually eclipsed by the Mydoom virus in 2004, which spread even more quickly. But Nimda remains one of the most dangerous viruses ever created..Original Article
The most dangerous computer virus ever: the story of theConficker virus
The Conficker virus is one of the most dangerous computer viruses of all time. It was first discovered in 2008, and it quickly spread to millions of computers around the world. The virus was especially dangerous because it was able to infect computers that were not connected to the Internet. This meant that the virus could spread quickly and easily, and it was very difficult to remove.
The virus was designed to take control of computers and to steal information. It could also be used to launch attacks on other computers. The virus was extremely difficult to remove, and it caused a great deal of damage to infected computers.
The virus was finally defeated in 2010, after a massive international effort to find and remove all of the infected computers. However, the virus is still present on some computers, and it could potentially cause a lot of damage if it is ever activated again.
