Komprogo Trojan Distribution Method

There are a few ways you can get infected with the “Komprogo” Trojan horse. The most common one is by installing it manually as a program that is pretending to be useful. Thus, without knowing, you are getting the Trojan inserted into your computer, instead. Another way to get infected is via browser exploits, such as plugins, extensions, or a suspicious site with malware on it.

You may get infected with the Trojan from a targeted attack by downloading an attachment from an email. Files that can be used to distribute Trojans like Komprogo, usually have these extensions: .bat, .exe, .vbs, .pif, .scr.

Komprogo Trojan Technical Description

Komprogo is classified as a backdoor type of Trojan horse. It has the potential to infect you with more malware, even currently active ransomware such as CryptoWall 4.0 and Av666@weekendwarrior55(.)com.

According to Symantec researchers, once Komprogo Trojan is executed, it immediately modifies the following Windows Registry entry:

→HKEY_CURRENT_USER\Software\Microsoft\Narrator\NoRoam\”ComponentName” = “C2F8037AA0BD29CD472402BC63079F558F647C9B”

Afterwards, it creates two new registry entries:

→ HKEY_CLASSES_ROOT\CLSID\{53255E7F-D464-40FB-857D-A2F9F0E1E397}\InProcServer32

→HKEY_CURRENT_USER\Software\Microsoft\Active Setup\Installed Components\{89B4C1CD-B018-4511-B0A1-5476DBF70820}

Then, the Trojan will try disabling services and programs, like the Network Information Service, SepMasterService, UMEngx86.dll and Norton Internet Security if you have such.

After these operations, the Trojan will create a back door, modify Windows Firewall settings, and connect remotely to the following locations:


Via that backdoor, Komprogo may perform a number of malicious actions. Such actions include:

  • Move, read, execute, download, create, delete, and copy files.
  • Enumerate running processes.
  • End processes.
  • Set, query, and delete registry values.
  • Execute arbitrary commands (any command selected by a hacker).
  • Upload user names to any of the remote locations.
  • Upload the computer name to any of the remote locations.

Via the connection to the remote locations, the hacker behind the Trojan may also steal sensitive data and files.
