From; Sophos Alert System: Name: W32/Agobot-MN Type: Win32 worm Date: 26 April 2004 A virus identity (IDE) file which provides protection is available now from the Sophos website, and will be incorporated into the June 2004 (3.82) release of Sophos Anti-Virus. Customers using Enterprise Manager, PureMessage and any of the Sophos small business solutions will be automatically protected at their next scheduled update. At the time of writing, Sophos has received just one report of this worm from the wild. Information about W32/Agobot-MN can be found at: http://www.sophos.com/virusinfo/analyses/w32agobotmn.html Description W32/Agobot-MN is an IRC backdoor Trojan and network worm. W32/Agobot-MN is capable of spreading to computers on the local network protected by weak passwords. When first run, W32/Agobot-MN copies itself to the Windows system folder as runtime.exe and creates the following registry entries to run itself on startup: HKLM\Software\Microsoft\Windows\CurrentVersion\Run\ smrtdrv = runtime.exe HKLM\Software\Microsoft\Windows\CurrentVersion\RunServices\ smrtdrv = runtime.exe On NT based versions of Windows the worm creates a new service named "Smart Drive" with a display name of "smrtdrv" and a startup property of automatic, so that the service starts automatically each time Windows is started. The Trojan runs continuously in the background providing backdoor access to the computer. The Trojan attempts to terminate and disable various anti-virus and security related programs and modifies the HOSTS file located at %WINDOWS%\System32\Drivers\etc\HOSTS, mapping selected anti-virus websites to the loopback address 127.0.0.1 in an attempt to prevent access to these sites. Typically the following mappings will be appended to the HOSTS file: 127.0.0.1 www.symantec.com 127.0.0.1 securityresponse.symantec.com 127.0.0.1 symantec.com 127.0.0.1 www.sophos.com 127.0.0.1 sophos.com 127.0.0.1 www.mcafee.com 127.0.0.1 mcafee.com 127.0.0.1 liveupdate.symantecliveupdate.com 127.0.0.1 www.viruslist.com 127.0.0.1 viruslist.com 127.0.0.1 viruslist.com 127.0.0.1 f-secure.com 127.0.0.1 www.f-secure.com 127.0.0.1 kaspersky.com 127.0.0.1 www.avp.com 127.0.0.1 www.kaspersky.com 127.0.0.1 avp.com 127.0.0.1 www.networkassociates.com 127.0.0.1 networkassociates.com 127.0.0.1 www.ca.com 127.0.0.1 ca.com 127.0.0.1 mast.mcafee.com 127.0.0.1 my-etrust.com 127.0.0.1 www.my-etrust.com 127.0.0.1 download.mcafee.com 127.0.0.1 dispatch.mcafee.com 127.0.0.1 secure.nai.com 127.0.0.1 nai.com 127.0.0.1 www.nai.com 127.0.0.1 update.symantec.com 127.0.0.1 updates.symantec.com 127.0.0.1 us.mcafee.com 127.0.0.1 liveupdate.symantec.com 127.0.0.1 customer.symantec.com 127.0.0.1 rads.mcafee.com 127.0.0.1 trendmicro.com 127.0.0.1 www.trendmicro.com Recovery Please follow the instructions for removing worms.
