Computer viruses can be extremely destructive. They can not only cripple a victim's computer, they can also extort money and even stymie a country's nuclear development. Here are five computer viruses that caused a ton of damage to their victims' machines.
A few months ago, science YouTube channel SciShow went through a list of the five most destructive computer viruses in history. This time, SciShow expanded the list with another five computer viruses or malicious software that caused a lot of headaches for those who were targeted:
- Chernobyl Virus: Surfaced in 1998 and rendered BIOS chips in targeted PCs unusable. It's still active today although it only targets computers that run Windows 95 or 98.
- Code Red: It launched a stealthy attack where it would randomly try to access an IP address and cause a buffer overflow. Around 360,000 computers were affected in under 14 hours, making it one of the fastest computer virus outbreaks of all time and caused USD$2.7 billion in damage.
- Cryptolocker: One of the most prolific ransomware that ever existed. It was officially shutdown in 2014 although variants of Crytolocker are still active.
- Bakasoftware: A Trojan also known as Antivirus XP 2008 and Spyware Protect 2009. It was designed to trick users into thinking that it was legitimate antivirus software.
- Stuxnet: The first known digital weapon deployed by a nation for strategic purposes of slowing down Iran's nuclear development. It was made to take out the centrifuges powering uranium enrichment in the Natanz enrichment plant in Iran.
