In 2004, the Mydoom virus, also known as Novarg, induced around $38 billion in damage. This computer virus was spread by mass emailing. The Mydoom virus works by scraping email addresses from infected machines. Then it will send a copy of itself to other machines connected to the same network that the infected was using. This kind of virus also brought infected devices into a botnet. If you are interested in computer hacking, you might already know that botnets were used for a hacking technique called DDoS or distributed denial of services.
According to the report, the main goal of the virus is to shut down the target server. This computer virus was designed to either infect the client in the network or compromise the server directly. After the incident, the Mydoom virus or "Novarg" was considered the worst computer virus in the world.
During its fame, the Novarg virus was responsible for 25% of all the emails sent throughout the world. But today, it is shocking that it was still existing, and reports said that it generated around 1% of all 3.4 billion phishing emails sent every day.
Until now, the creator of the worst computer virus is still unknown, even though a $250,000 reward was offered.
If you encounter any of these symptoms, run a scan test on your device with the help of antivirus programs such as Windows Defender, Avast Antivirus, etc.
First, always update the software on your PC. There are lots of cyber security services that ensure that all of your software is up-to-date.
Second, always turn on your Windows firewall and Windows Defender (for Windows users). This will help you filter all the files and resources that were going in and out of your computer. It would be best to consider scanning your PC for threats and malware.
Lastly, do not click or open suspicious files or links. Hackers hid most of the viruses in what we called trojan. This trojan acts as a carrier and disguises itself as files, software, etc. When you see a suspicious file on your PC or someone wants you to open the file, and you feel that it was a little shady. Go to virustotal.com and scan the file for possible threats.
