W32/Agobot-PR spreads using a variety of techniques including exploiting weak passwords on computers and SQL servers, exploiting operating system vulnerabilities (including DCOM-RPC, LSASS, WebDAV and UPNP) and using backdoors opened by other worms or Trojans. When first run W32/Agobot-PR copies itself to the Windows system folder as SRV325.EXE and creates the following registry entries to run itself on startup: HKLM\Software\Microsoft\Windows\CurrentVersion\Run Srv325 Srv325.exe HKLM\Software\Microsoft\Windows\CurrentVersion\RunServices Srv325 Srv325.exe Each time W32/Agobot-PR is run it attempts to connect to a remote IRC server and join a specific channel. W32/Agobot-PR then runs continuously in the background, allowing a remote intruder to access and control the computer via IRC channels. 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 Patches for the operating system vulnerabilities exploited by W32/Agobot-PR can be obtained from Microsoft at: http://www.microsoft.com/technet/security/bulletin/ms04-012.mspx http://www.microsoft.com/technet/security/bulletin/ms03-039.mspx http://www.microsoft.com/technet/security/bulletin/ms03-007.mspx http://www.microsoft.com/technet/security/bulletin/ms01-059.mspx from Sophos plc.Fri, 11 Feb 2005 14:14:39 +0000 (GMT) -- Üdvözlettel, Geza mailto:[EMAIL PROTECTED] _______________________________________________ Full-Disclosure - We believe in it.
