What was the most dangerous computer virus of all time?
In May 2017, the WannaCry ransomware attack spread rapidly across the globe, affecting more than 200,000 victims in 150 countries. The cyberattack caused major disruptions to healthcare, banking, and other critical infrastructure. WannaCry encrypted files on infected computers and demanded a ransom of $300-$600 in Bitcoin in order to decrypt the files. The WannaCry attack was particularly worrisome because it took advantage of a previously unknown software vulnerability, which meant that many organizations were unprepared to defend against it.
While the WannaCry attack was certainly one of the most disruptive and costly cyberattacks in recent history, it is not the most dangerous computer virus of all time. That dubious distinction goes to the malware known as Flame.
Flame was discovered in 2012, but it is believed to have been active since at least 2010. Unlike WannaCry, which was designed to spread quickly and indiscriminately, Flame was a carefully targeted attack that was used to gather intelligence. The malware was used to spying on computers in Iran, Syria, Lebanon, Saudi Arabia, and Egypt. Flame was able to steal a variety of information from infected computers, including emails, instant messages, and audio conversations. It could also take screenshots, collect information about the network environment, and hijack the victim’s webcam and microphone to record conversations and activities in real-time.
Flame was particularly sophisticated because it was designed to spread stealthily and avoid detection. It used a variety of methods to infect victim’s computers, including USB drives and infected emails. Once Flame had infected a computer, it would wait patiently for up to two weeks before beginning to collect information. This allowed the malware to avoid detection by anti-virus software, which is typically designed to identify and remove threats that exhibit suspicious behavior immediately after infection.
The Flame malware was finally discovered when it caused a computing shutdown at the Iranian oil ministry. After the discovery, Microsoft released a security update to close the vulnerability that Flame had exploited.
While WannaCry was a devastating ransomware attack that affected a large number of people, it did not have the same insidious intent or sophisticated design as Flame. For these reasons, Flame is considered to be the most dangerous computer virus of all time.

What is the most common computer virus?
There is no definitive answer to this question, as the most common computer virus tends to differ from region to region and change over time. However, some of the most common viruses in recent years include the WannaCry virus, which targeted Microsoft Windows users, and the Petya virus, which primarily affected users in Ukraine.
