What Is MyDoom?
It was first seen on January 26th, 2004.
MyDoom was named by Craig Schmugar, an employee ofMcAfeecomputer security company.
He was also one of the earliest discoverers of the virus.
Craig selected this name since he noticed the text mydoom within a line of theMyDoom source code.
It was evident early on that this would be very big.
I thought having doom in the name would be appropriate, said Craig.
Who Created MyDoom?
MyDoom worm appears to have been commissioned by email spammers to deliver junk e-mails via infected computers.
That prompts speculation that theMyDoom computer viruswas created by the same author as the virus Mimail.
Later analyses were less conclusive as to the link between the two viruses.
Around 25% of Mydoom.A-affected computers targeted SCO Group with a flood of traffic.
However, this theory was rejected immediately by security researchers.

How Does MyDoom Spread?
Some early reports held that the virus avoids all .edu addresses, but its not true.
The initial version MyDoom.A is thought as carrying 2 payloads.
This is essentially the same backdoor as what was found in Mimail.

Yet, not a few virus analysts doubted whether the payload would actually work or not.
Later test shows that it functions in only 25% of affected systems.

MyDoom Virus History / MyDoom Virus Effect
Below is the timeline of the MyDoom Virus event.
The earliest emails originated from Russia.
It was reported that MyDoom malware was responsible for about 10% of email messages then.
Whether MyDoom itself was responsible for this or not is unknown.
In the United States, the FBI and the Secret Service started investigating the virus.
January 28, 2004
Mydoom.b was discovered.
The first message sent by it was identified at about 1400 UTC and also appeared to originate from Russia.
On this day, the spread of MyDoom was at its peak.
Security companies reported that MyDoom was responsible for approximately 20% of emails that day.
Read this post to find the answer.
Microsoft offered a $250,000 reward for information leading to the arrest of the creator of MyDoom B.
On this day, the virus arrived in Australia and East Asia.
SCO removed www.sco.com from theDNSaround 1700 UTC on January 1st.
Luckily, MyDoom virus damage remained minimal and microsoft.com remained functional during the attack.
February 9, 2004
Doomjuice, a parasitic virus, began spreading.
It made use of the backdoor left by MyDoom to spread.
Doomjuice didnt attack non-affected machines.
Its payload, similar to one of MyDoom.Bs, is also a denial of service aiming at Microsoft.
February 12, 2004
MyDoom.A is programmed to stop spreading.
Yet, the backdoor remains open after this date.
March 1, 2004
MyDoom.B is programmed to stop spreading.
Similar to MyDoom A, its backdoor remains open.
