More Information
Troj/Tofger-I is a keylogger Trojan that arrives as a dropper.
The dropper drops the two components of Troj/Tofger-I into the Windows folder as sxchost.exe and doru32.dll.
Troj/Tofger-I uses <Windows>\sdsini.ini as a log file. The dropper also sets the following registry entry:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run\
Upgrade Service= <Windows folder>\sxchost.exe
The dropper then runs sxchost.exe.
When run, Troj/Tofger-I logs keypresses into sdsini.ini and from time to time sends the logged data to a predefined email address.
