Thread: Attention Everyone Using Kazaa And Irc

  1. #1
    There is a new worm going around on Kazaa and IRC. On IRC, it automatically sends it self to everyone in the channel and on Kazaa, it poses as "Kazaa Media Desktop", and other software. So if you are downloading stuff unverified, watch out. Also, It may pose as an official update from Microsoft. Read the article here and here.


    New Worm Targets File-Sharing Nets
    Thu Sep 18, 6:00 PM ET 

    Antivirus companies are warning Internet users about W32.Swen, a new worm that spreads using e-mail messages, vulnerable network connections, Internet Relay Chat (IRC), and peer-to-peer networks.

    F-Secure, Network Associates, and Symantec all have issued warnings about Swen, indicating that the worm is spreading on the Internet. Customers are being advised to update their antivirus definitions to detect and nullify Swen.

    Finding a Flaw

    First detected on Thursday, Swen exploits a security hole in Microsoft's Internet Explorer Web browser. It affects all supported versions of the Windows operating system, according to security products vendor F-Secure of Helsinki.


    The worm poses as a software security update from Microsoft. Its message prompts users with "Yes" or "No" buttons to agree to install the update, and even provides an installation "progress" bar if they do agree.


    However, the worm code is installed regardless of what users select. Once it has infected a system, Swen alters the configuration of Windows so the worm is launched whenever Windows is started. The worm also detects and disables antivirus software or other Windows features that could be used to disable it, according to F-Secure.


    Like other mass mailing worms, Swen scans an infected machine's hard drive for e-mail addresses and uses those to send out more copies of itself, skimming SMTP server addresses and user names from Windows.


    Infected e-mail messages are formatted to look like official correspondence from Microsoft. The messages appear to come from one of a variety of randomly generated senders like "MS Technical Assistance" and advertise a "cumulative patch" for Internet Explorer to patch "three newly discovered vulnerabilities," F-Secure says.

    Other Routes

    The worm also can detect the presence of IRC clients or the Kazaa peer-to-peer file-sharing client application, and then distribute itself on those networks. Swen places a specialized script file that sends a virus file to every computer on the same IRC channel as the infected computer.


    For machines running Kazaa file-sharing software, Swen enables the file-sharing feature, if it is not already enabled. It places multiple copies of itself in the Kazaa shared files folder, disguised as Kazaa client software, pirated software, or other popular applications, F-Secure says.


    More than one antivirus company notes the similarity between Swen and an earlier worm, W32.Gibe, which appeared in March. Like Swen, Gibe also attempted to spread by e-mail as well as Kazaa and IRC networks, while posing as a piece of legitimate Microsoft software when installed.
