 As the internet world has grown, a new form of crime has emerged: cybercrime.

Most dangerous viruses in history


His weapons? Computer viruses, of different kinds: worms, malware, ransomware … so many variants that have the same purpose: to hack the computers they have targeted.

If antivirus and other cybersecurity completesecurity systems have also continued to improve, some famous cases in history are there to attest that good protection in this area is not in vain, in view of the considerable damage that can be caused. generated ... Choosing a  quality antivirus  is then more than recommended. A look back at the cyber attacks that marked the history of computing.

Stuxnet

Perhaps the most famous of all. This computer worm designed by the United States was used to disrupt the operation of centrifuges at an Iranian nuclear power plant and cause their destruction. The modus operandi was as follows: the Stuxnet worm entered a Windows operating system via an external device, before deeply infecting one of the files and duplicating it endlessly in all the other stations on the network.

It especially marked the spirits because it was the first time in history that a computer virus caused material damage to a physical infrastructure.

Zeus

Identified in 2009, the Zeus virus has made a name for itself by infiltrating the sites of world-famous companies such as Cisco, Bank of America, Oracle or Amazon. The Trojan horse obtained the credentials of users on social networks before stealing their banking data by retrieving registration forms.

Code Red

If one day you saw the message "Hacked by Chinese" appear on your screen, then you must have a bitter memory of the Code Red virus. Identified in 2004, it reaches posterity for having succeeded in infecting the servers of the White House and causing them damage estimated at around 2.5 million euros.

MyDoom

Identified in 2004, MyDoom made an impression with its exponential proliferation which was able to contaminate more than 2.5 million computers in record time. Its crazy spread was possible thanks to its infection process, carried out by email, aimed at stealing the address books of its victims. The damage he could cause is estimated at more than 25 million euros.

Sasser

Targeting large companies and important public infrastructures, such as airlines, hospitals or news agencies, the Sasser virus has broken sad records in terms of damage caused: close to 15 billion euros!

Once the targeted computer got infected with the virus, it would then download software that it ran without the knowledge of its user. In a second step, this software searched for all the other computers in the network without protection and infected them in turn.

Let it be said, computer systems have evolved, but so have viruses! The best way to protect yourself is therefore to go through a reliable and regularly updated antivirus!
