The Trojan injects its code into the following process(es):

svchost.exe:1604

Mutexes

The following mutexes were created/opened:No objects were found.

File activity

The process %original file name%.exe:204 makes changes in the file system.

The Trojan creates and/or writes to the following file(s):

%Documents and Settings%\%current user%\Application Data\Microsoft\Windows%original file name%.exe (4185 bytes)

The process dumprep.exe:532 makes changes in the file system.

Registry activity

The process %original file name%.exe:204 makes changes in the system registry.

The Trojan creates and/or sets the following values in system registry:

[HKLM\SOFTWARE\Microsoft\Cryptography\RNG]
"Seed" = "96 80 87 58 4C 61 56 71 DE 6C A1 F8 58 7D DB 2E"

[HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders]
"AppData" = "%Documents and Settings%\%current user%\Application Data"

"Cache" = "%Documents and Settings%\%current user%\Local Settings\Temporary Internet Files"

To automatically run itself each time Windows is booted, the Trojan adds the following link to its file to the system registry autorun key:

[HKCU\Software\Microsoft\Windows\CurrentVersion\Run]
"Firefox" = "c:\%original file name%.exe"

"winini" = "%Documents and Settings%\%current user%\Application Data\Microsoft\Windows%original file name%.exe"
