Giant Internet worm set to change tactics April 1
By JORDAN ROBERTSON – 32 minutes ago
SAN FRANCISCO (AP) — The fast-moving Conficker computer worm, a scourge of the Internet that has infected at least 3 million PCs, is set to spring to life in a new way on Wednesday — April Fools' Day. (Careful...this could be a joke...)
That's when many of the poisoned machines will get more aggressive about "phoning home" to the worm's creators over the Internet. When that happens, the bad guys behind the worm will be able to trigger the program to send spam, spread more infections, clog networks with traffic, or try and bring down Web sites.
Technically, this could cause havoc, from massive network outages to the creation of a cyberweapon of mass destruction that attacks government computers. But researchers who have been tracking Conficker say the date will probably come and go quietly.
More likely, these researchers say, the programming change that goes into effect April 1 is partly symbolic — an April Fools' Day tweaking of Conficker's pursuers, who for now have been able to prevent the worm from doing significant damage.
"I don't think there will be a cataclysmic network event," said Richard Wang, manager of the U.S. research division of security firm Sophos PLC. "It doesn't make sense for the guys behind Conficker to cause a major network problem, because if they're breaking parts of the Internet they can't make any money."
Previous Internet threats were designed to cause haphazard destruction. In 2003 a worm known as Slammer saturated the Internet's data pipelines with so much traffic it crippled corporate and government systems, including ATM networks and 911 centers.
Far more often now, Internet threats are designed to ring up profits. Control of infected PCs is valuable on the black market, since the machines can be rented out, from one group of bad guys to another, and act as a kind of illicit supercomputer, sending spam, scanning Web sites for security holes, or participating in network attacks.
The army of Conficker-infected machines, known as a "botnet," could be one of the greatest cybercrime tools ever assembled. Conficker's authors just need to figure out a way to reliably communicate with it.
Infected PCs need commands to come alive. They get those commands by connecting to Web sites controlled by the bad guys. Even legitimate sites can be co-opted for this purpose, if hackers break in and use the sites' servers to send out malicious commands.
So far, Conficker-infected machines have been trying to connect each day to 250 Internet domains — the spots on the Internet where Web sites are parked. The bad guys need to get just one of those sites under their control to send their commands to the botnet. (The name Conficker comes from rearranging letters in the name of one of the original sites the worm was connecting to.)
