    Panda Security''s weekly report on viruses and intruders

    Mensagem por Admin em Sex 15 Maio 2009 - 13:40

    - Virus Alerts, by Panda Security (http://www.pandasecurity.com)

    PandaLabs' report this week focuses on three worms: IRCBot.CNE, BckPatcher.C and Boface.BJ.

    IRCBot.CNE sends messages to the infected user's MSN Messenger contacts.
    Message subjects include:

    * Me miro boracho en video que me tomaron en youtube (I see myself
    drunk in a video on youtube).
    * Esta es mi casa de suenos!! (this is my dream house)
    * Mira que pedo andaba ayer en la fiesta (look how drunk I was at
    yesterday's party)
    * No me acuerdo si me dormir con esta vieja??no se que hacer? (I
    can't remember if I slept with this woman yesterday. I don't know what to do)
    * Santo Dios creo que eres tu!!!! (Oh my God, I think it's you!)

    These messages include an attachment which is a copy of the worm. On running the file, users are infected with a copy of the worm.

    BckPatcher.C on the other hand, is designed to modify the desktop background, the Windows Explorer background and the folder icons.
    Additionally, every time files with certain extensions are executed (DLL, EXE, JPG or RAR) the worm is run instead of the applications associated to those extensions.

    BckPatcher.C spreads through shared, mapped and removable drives, copying itself to them.

    You can see images of the modifications carried out by the worm here:

    The Boface.BJ worm reaches computers in a different way: through email messages with attachments, Internet downloads, files transferred via FTP, IRC channels, P2P file-sharing networks, etc. Users are unaware of the infection.

    Once the PC is infected, it takes approximately four hours to trigger its payload. It does so when users access log into their Facebook account. Then, it uses the network to send them a message, including the affected user. http://www.flickr.com/photos/panda_security/3528707512/

    On clicking the link users are directed to a page that resembles YouTube (called "YuoTube") in which a video "should" be displayed. However, in order to do so, users are asked to download a player. If users accept, the fake antivirus is downloaded. Image here:

    Once the download is accepted, the fake antivirus is installed on the computer. It then starts sending users messages informing them their PC is infected and telling them they should buy a solution. Here is the interface displayed by one of the fake antiviruses:

    More information about these and other malicious codes is available in the Panda Security Encyclopedia
    ((http://www.pandasecurity.com/homeusers/security-info)

    Finally, Panda Security has launched a page for users to relate their experiences with malware (whether they have fallen victim to money or data theft, etc.). Users who send their comments will receive a free download of Panda Internet Security 2009 with two-month services. Check it out here:
    http://www.pandasecurity.com/homeusers/media/malware-stories/

    You can follow Panda Security's activity online on Twitter (http://www.twitter.com/panda_security), and the PandaLabs blog
