MyDoom is a notorious Windows email worm first discovered on Jan. 26, 2004 , which remains the fastest-spreading email malware in history and continues to circulate in automated phishing campaigns today.
The worm allowed hackers to access infected email accounts and send spam, spreading further whenever users opened infected email attachments.
At its peak in 2004, it accounted for roughly one in four emails sent worldwide and caused an estimated $38 billion to $55 billion in economic damage.
Craig Schmugar, a researcher at the computer security company McAfee, was among the first to analyze Mydoom, according to History.com . He coined its name after noticing the word “mydom”—short for “my domain”—in the virus’s code.
MyDoom was a doozy. Watch the latest Cybercrime Magazine History of Hacking YouTube Short Video with our Senior Social Media Manager Taylor Fox.
