    Trend Micro Medium Risk Virus Alert - WORM_KELVIR.B and WORM_FATSO.A

    As of March 7, 2005, 3:05 AM (GMT - 08:00), TrendLabs has declared a Medium Risk Virus Alert to control the spread of WORM_KELVIR.B and WORM_FATSO.A. TrendLabs has received numerous infection reports indicating that this malware is spreading in Korea and the United States of America.


    This new worm is very similar to WORM_KELVIR.A, in that it also propagates via MSN messenger. It attempts to send the following instant message to all online MSN messenger contacts of an affected user:

    "http://home.ea<BLOCKED> lol! see it! u'll like it"

    When the user clicks the given URL, this worm downloads a copy of itself, named OMG.PIF, from the given URL. When this downloaded copy is executed, it downloads another malware file from the Internet, which Trend Micro detects as WORM_SDBOT.AUI.


    This memory-resident worm arrives on a system via MSN messenger, a popular instant messaging application. It spreads copies of itself to all online MSN messenger contacts of an affected system by sending an instant message conataining a link, which when clicked, downloads a copy of this worm into the recipient's system. This worm also has the ability to propagate via eMule, a known peer-to-peer (P2P) file sharing application.

    This worm is capable of redirecting infected users to a certain Web site, which as of this writing, is already not available. It does this whenever the user accesses Web sites that are associated with antivirus and security companies.

    It may also terminate certain running processes, and disallow them from executing while this worm resides in the memory.

    TrendLabs will be releasing the following EPS deliverables:

    TMCM Outbreak Prevention Policy 154
    Official Pattern Release 2.476.00
    Damage Cleanup Template 550
