Computer viruses and spyware / the most dangerous virus
« Last post by Phoebe75 on September 19, 2023, 09:16:55 AM »As of my last knowledge update in September 2021, there were several dangerous computer viruses, malware, and ransomware circulating. However, the landscape of computer threats is constantly evolving, so the most dangerous virus can change over time. Here are a few examples of highly dangerous viruses and malware that were prominent up to 2021:
WannaCry: This ransomware spread rapidly in 2017, encrypting files on Windows computers and demanding a ransom for decryption. It caused widespread disruptions, especially in healthcare systems.
Conficker: This worm, first detected in 2008, exploited vulnerabilities in Windows operating systems to create a massive botnet. It's estimated that millions of computers were infected.
Mydoom: This email worm, which emerged in 2004, was one of the fastest-spreading ever. It was used for sending spam and launching denial-of-service attacks.
Stuxnet: Discovered in 2010, Stuxnet was a highly sophisticated worm that specifically targeted supervisory control and data acquisition (SCADA) systems. It was allegedly developed by nation-states to disrupt Iran's nuclear program.
Zeus/Zbot: This banking trojan has been responsible for stealing sensitive financial information from millions of victims worldwide. It's been used in various cybercriminal operations.
NotPetya/ExPetr/Petya: These ransomware attacks, which started in 2016, spread quickly and caused massive disruptions, especially in Ukraine. They were later attributed to state-sponsored actors.
Emotet: Originally a banking trojan, Emotet evolved into a powerful malware delivery service. It was often used to distribute other malware, such as TrickBot and Ryuk ransomware.
Please keep in mind that new threats may have emerged since my last update. To protect your computer from viruses and malware, it's crucial to maintain up-to-date antivirus software, regularly apply security patches, use strong, unique passwords, and exercise caution when clicking on links or downloading files from unknown sources. Additionally, consider creating backups of important data to mitigate the impact of ransomware attacks.
