From; Sophos Alert System: Name: W32/Sdranck-C Aliases: WORM_SDBOT.DTR Type: Win32 worm Date: 8 April 2005 A virus identity (IDE) file which provides protection is available now from the Sophos website, and will be incorporated into the June 2005 (3.94) release of Sophos Anti-Virus. Customers using EM Library, PureMessage or any of our Sophos small business solutions will be automatically protected at their next scheduled update. At the time of writing, Sophos has received a small number of reports of this worm from the wild. Information about W32/Sdranck-C can be found at: http://www.sophos.com/virusinfo/analyses/w32sdranckc.html W32/Sdranck-C is a Windows worm that spreads via network shares, drops files and contains backdoor functions that allow unauthorised remote access to the infected computer via IRC channels. When run, the delivery component of the worm drops the files imaxavos.exe (the worm core) and ikusefote.exe into the C:\WINNT\SYSTEM32 folder and then proceeds to run both files. ikusefote.exe is detected by Sophos as Troj/Ranck-CP. imaxavos.exe is being detected by Sophos as W32/Sdranck-C. When imaxavos.exe is executed it copies itself to the Windows System folder as ihotunib.exe. W32/Sdranck-C then creates the following registry entries so that it is able to run on user logon: HKLM\Software\Microsoft\Windows\CurrentVersion\Run Adiliwut ihotunib.exe HKLM\Software\Microsoft\Windows\CurrentVersion\RunServices Adiliwut ihotunib.exe HKCU\Software\Microsoft\Windows\CurrentVersion\Run Adiliwut ihotunib.exe The worm will also try to download and run files from the internet, terminate processes and add or delete network shares when instructed to do so by a remote attacker. W32/Sdranck-C attempts to copy itself to network shares using the main dropper component filename rudim.exe.
