Threat Details:
Categories:
trojan
Description:
Rana is a trojan that enables complete control over another computer via internet. It hides in the windows folder under the names ctfmon32.exe, logon.exe and starts through a file in the autorun folder named svchost.exe. These files must not be mixed up with original Windows files with the same/similar names.
Removal Instructions:
Autorun:
Please use Spybot-S&D (http://www.safer-networking.org/index.php?page=spybotsd), RunAlyzer (http://www.safer-networking.org/index.php?page=runalyzer) or msconfig.exe to remove the following autorun entries.
Entries named "ctfmon" and pointing to "<$WINDIR>\ctfmon32.exe".
Entries named "logon" and pointing to "<$WINDIR>\logon.exe".
Files:
Please use Windows Explorer or another file manager of your choice to locate and delete these files.
The file at "<$PROGRAMS>\Autostart\svchost.exe".
The file at "<$WINDIR>\ctfmon32.exe".
The file at "<$WINDIR>\logon.exe".
A file with an unknown location named "RANA.exe".
Make sure you set your file manager to display hidden and system files. If Rana uses rootkit technologies, use our RootAlyzer (http://forums.spybot.info/downloads.php?id=8) or our Total Commander anti-rootkit plugins (http://forums.spybot.info/downloads.php?id=3).
You will have to use a global search for files without a name specified. Be extra careful, because just the name might not be enough to identify files!
Important: There are more files that cannot be safely described in simple words. Please use Spybot-S&D (http://www.safer-networking.org/index.php?page=spybotsd) to remove them.
Final Words:
If neither Spybot-S&D nor self help did resolve the issue or you would prefer one on one help,
Please read these instructions (http://forums.spybot.info/showthread.php?t=288) before requesting assistance,
Then start your own thread in the Malware Removal Forum (http://forums.spybot.info/forumdisplay.php?f=22) where a volunteer analyst will advise you as soon as available.
