Sober worm goes into hibernation
The Sober.P worm stopped spreading across the Internet on Tuesday after virus writers remotely silenced thousands of infected computers overnight, experts said on Friday.
The worm, which spread rapidly last week, included code to make it respond to instructions posted on a number of Web sites. Antivirus companies now believe that the virus writers responsible for Sober.P made changes to these Web sites to temporarily stop the worm spreading.
Antivirus company F-Secure saw the worm drop to one percent of virus activity on Tuesday morning from 40 percent of virus activity on Monday — although rival antivirus company Sophos had reported that Sober.P was 84 percent of virus activity on Monday.
