Fast spreading MyDoom worm marks first big
attack of 2004 [PC Pro] 11:56
Tuesday 27th January 2004 The
first big worm attack of 2004 is spreading fast throughout the world today. The
MyDoom worm, which is a variant of the MiMail virus, spreads via email or to any
available shared directories used by Kazaa.
The worm harvests email
addresses from the hard disk and then generatees randomly-chosen addresses for
both the 'to' and 'from' fields. This means that the 'from' address is spoofed
and does not tell the next victim where the mail came from.
The subject lines of
the worm include such things as 'error', 'hello', 'hi', 'mail delivery system'
or 'mail transaction failed'. The worm can arrive either as an .exe or .zip
attachment and can appear as a text file icon although it is an executable.
MyDoom-A copies itself
to the System folder with the name taskmon.exe. it also drops the backdoor
program shimgapi.dll, which is loaded by the worm. The backdoor allows a hacker
access to TCP port 3127 on the computer. The worm also amends the registry so
that it loads every time the computer is switched on.
According to security
firm Sophos, the backdoor access has been designed to launch a denial of service
(DoS) attack against SCO's website.
By midnight,
MessageLabs estimated that it had intercepted some 165,000 copies of the worm
yet was still spreading rapidly.
