    McAfee, Trend, and other AV vendors have declared this as MEDIUM RISK due to prevelance in-the-wild.

    MyDoom.S - MEDIUM RISK

    This virus is received in an email message as follows:

    From: <spoofed>

    SOME BAD NEWS ON THIS ONE: If MyDoom.S infects your PC, it will attempt to download BackDoor-CHR. Once this stealthing driver is running on the victim machine, this threat is not detected by conventional AV scanning methods.

    BackDoor-CHR - hidden backdoor installed by MyDoom.S

    This remote access trojan is downloaded by W32/Mydoom.s@MM . It bears the following characteristics:

    * stealths its activity on the victim machine
    * serves as a HTTP and SMTP proxy
    * attempts to connect to numerous remote IRC servers
    appends the local hosts file (in an attempt to disable updating of many AV products)
    * The trojan attempts to connect to a remote IRC server to await command. It carries a list of IP addresses and relevant ports for these servers ...

    Trend Newsletter: WORM_RATOS.A

    WORM_RATOS.A is a memory-resident, mass-mailing worm that arrives with an attachment that is a copy of the worm. It collects email addresses from the Windows Address Book, searching temporary Internet files, and by querying certain entries in the Windows registry. It also constructs email addresses by prepending certain names to popular domain names. In addition, this worm downloads and executes a backdoor component file from several URLs, enabling remote access to the infected machine and therefore comprising user and system security. WORM_RATOS.A is a variant of the MYDOOM family of worms, and will be renamed as WORM_MYDOOM.S shortly. This worm is currently spreading in-the-wild and infecting systems running Windows 95, 98, ME, NT, 2000, and XP.

    Upon execution, this memory-resident worm drops a copy of itself as the following:

    It also adds registry entries that allow it to run at every Windows startup.

    This worm sends a copy of itself via email by harvesting email addresses from files found in the temporary Internet files folder, with any of the following extension names: ADB ASP DBX HTM PHP SHT TBB TXT WAB

    It also checks for recipient email addresses in the Windows Address Book. In addition, it constructs email addresses by prepending the following names to the domain names aol.com, hotmail.com, msn.com, and yahoo.com: adam alex alice andrew anna bill bob brenda brent brian claudia dan dave david debby fred george helen jack james jane jerry jim jimmy joe john jose julie kevin leo linda maria mary matt michael mike peter ray robert sam sandra serg smith stan steve ted tom

    It sends email with the following details:
