WP gets his 15 minutes of fame: "A new computer "worm"
called ExploreZip is not yet spreading as quickly as the Melissa virus did, but has the potential to be much more costly, said Wes Wasson, director of product marketing in Network Associates Inc.'s Security Division.
That's because while the Melissa virus simply clogged victims' e-mail boxes with messages containing lists of pornographic Web sites, ExploreZip actually begins to delete files on the hard drives of infected computers, Mr. Wasson said.
Mr. Wasson said that ExploreZip is technically not a virus, which replicates itself, but rather a computer worm, which spreads itself by other means.
In the case of ExploreZip, the worm spreads through Microsoft Corp. e-mail programs like Explorer and Outlook. Mr. Wasson said Network Associates has not yet determined if the worm is also spreading through other e-mail programs.
ExploreZip is activated when a user opens an executable program with the file name "zipped_files.exe" attached to an incoming e-mail message containing the worm. Once activated, the worm not only begins to delete files on the infected computer's hard drive, but also replicates itself by responding to all incoming e-mail messages -- sending itself out as an attachment.
Network security experts believe ExploreZip, which was first detected Wednesday, originated in Israel.
Mr. Wasson estimates the number of ExploreZip infections is already "at least in the thousands" and could increase over the coming days. He pointed out that a recipient is likely to open a file containing the worm since it will probably look as if it is coming from an acquaintance.
Network Associates has already received reports of infections from major corporations in the U.S., Germany and France.
The company, which regularly performs risk assessments on computer viruses and worms, has upgraded its rating on ExploreZip to "high" -- its top rating -- from "medium."
Mr. Wasson noted that this is only the third "high" rating assigned by the company since the Melissa virus hit.
Consumers who fear that their computers have been infected by the worm can go to the McAfee Clinic on Network Associates' McAfee.com Web site (www.mcafee.com) for a free scan. |
