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.
MyDoom.O is much more clever in imitating the kind of notification
messages computer users are used to getting when their messages are
returned as undeliverable.
