MyDoom.O is much more clever than earlier MyDoom variants in imitating the kind of notification messages computer users are used to getting when their messages are
returned as undeliverable. MyDoom.O is also more talented at replicating itself than earlier versions of the worm.

Computer virus companies spent yesterday scampering to develop defenses
for the newest strain of the MyDoom virus, dubbed MyDoom.O. By mid
morning yesterday, thousands of e-mail inboxes were filling up with
MyDoom.O subject lines -- and even specifically forged e-mail 
header information
-- designed to encourage opening.
This latest MyDoom worm variant of the original MyDoom family was spreading more quickly
than its MyDoom cousins because of human gullibility, according to computer
security experts.
"This one is much more successful in looking like a bounced or returned
e-mail message," Charles Kaplan, managed security services information
security officer at VeriSign (Nasdaq: VRSN), told TechNewsWorld.

New MyDoom Variant Stalks More Victims
July 26, 2004
MyDoom.O is more talented at replicating itself than earlier versions of
the worm. The latest version takes the domain names it finds and
searches the four major search engines for all known e-mail addresses at
the target domains. The MyDoom.O variant also has a back door component
that will let hackers continue to take over computers already
compromised by other virus infections.
