What is the most dangerous computer virus ever created?
There is no definitive answer to this question as it depends on a number of factors, including the objectives of the person or organization who created the virus, how widespread it is, and how destructive it is. However, some of the most dangerous viruses ever created include the following:
1. CodeRED: CodeRED was a worm that was released in 2001 and quickly spread across the internet, infecting over 250,000 computers in just a few days. The worm took advantage of a flaw in Microsoft’s Internet Information Server (IIS) software, allowing it to remotely execute code on vulnerable systems. Once a system was infected, the worm would scan for other vulnerable systems and infect them as well, creating a network of infected machines, or a botnet. CodeRED was used to launch a number of attacks, including denial of service attacks and attempts to gain access to sensitive information.
2. ILOVEYOU: ILOVEYOU was a virus that spread via email in 2000. The virus was disguised as a love letter, and when opened, would copy itself to all of the victim’s email contacts. The virus would then send itself out to those contacts, continuing to spread the infection. ILOVEYOU was particularly dangerous because it was able to replicate itself very quickly and caused a great deal of damage, with estimates of up to $10 billion in damages.
3. Melissa: Melissa was a virus that spread via email in 1999. Similar to ILOVEYOU, the virus was disguised as a love letter and, when opened, would copy itself to the victim’s email contacts. Melissa was not as destructive as ILOVEYOU, but it was still able to spread very quickly, causing massive amounts of email traffic and resulting in mailbox shutdowns at many organizations.
4. MyDoom: MyDoom was a virus that was released in 2004 and quickly became the fastest-spreading email worm of all time. The virus was disguised as an email with an attachment, and when opened, would email itself to all of the victim’s contacts. MyDoom was used to launch denial of service attacks against a number of websites, including the website of the United States Department of Homeland Security.
5. Sasser: Sasser was a worm that was released in 2004 and took advantage of a flaw in the Windows operating system. The worm would spread itself automatically by scanning for vulnerable systems and then exploiting the flaw to gain remote access. Once a system was infected, the worm would attempt to disable a number of system functions, including the ability to log in and access the internet. Sasser caused a great deal of disruption, with estimating the total cost of the outbreak at over $1 billion.
These are just a few of the most dangerous computer viruses ever created. There are many other viruses that have caused a great deal of damage, but these five illustrate the destructive power that a virus can have.
What is the most common type of computer virus?
According to Kaspersky, the most common type of computer virus is a Trojan. A Trojan is a type of malicious code or software that hides on your computer and waits for the opportunity to strike. Trojans can be used to steal your personal information, like your login credentials or banking information. They can also be used to install other types of malware, like ransomware, that can lock you out of your computer or encrypt your files until you pay a ransom.
