Conficker worm digs in around the world

SAN FRANCISCO - Computer security top guns around the world watched warily as the dreaded Conficker worm squirmed deeper into infected machines with the arrival of an April 1st trigger date.

The malicious software evolved, as expected, from East to West, beginning in time zones first to greet April Fool’s Day.

“Planes are not going to fall out of the sky and the Internet is not going to melt down,” said threat analyst Paul Ferguson of Trend Micro computer security firm in Northern California.

“The big mystery is what those behind Conficker are going to do. When they have this many machines under their control it is kind of scary. With a click of a mouse they could get thousands of machines to do whatever they want.”

A task force assembled by Microsoft has been working to stamp out the worm, referred to as Conficker or DownAdUP, and the US software colossus has placed a bounty of 250,000 dollars on the heads of those responsible for the threat.

The worm was programmed to modify itself on Wednesday to become harder to stop and began doing that when infected machines got cues, some from websites with Greenwich Mean Time and others based on local clocks.

Conficker task force members tracking Internet traffic in Asia and Europe after clocks struck April 1st there said there was no sign that the worm was doing anything other than modifying itself to be harder to exterminate.

Conficker had been programmed to reach out to 250 websites daily to download commands from its masters, they said, but on Wednesday it began generating daily lists of 50,000 websites and reaching randomly to 500 of those.

The hackers behind the worm have yet to give it any specific orders. An estimated one to two million computers worldwide are infected with Conficker.

Computer security specialists warn that the Conficker threat will remain even if April 1st passes without it causing trouble.

“It doesn’t seem to be doing anything right now,” Ferguson said as Conficker made its way to the western United States.

“I hope April 1st comes and goes with no trouble. But, there is this loaded pistol looming large out there even if no one has pulled the trigger.”
