darkcomet.exe

What is darkcomet.exe?

darkcomet.exe is the executable component of the DarkComet RAT, a modular remote access tool historically used by attackers to control compromised Windows machines. It often runs in the background and can be configured to listen for commands from a control server, capture keystrokes, screenshots, and exfiltrate data.

DarkComet is a modular RAT that provides remote access: keylogging, file browse, screen capture, and commands from a C2 server. It often installs as a service or startup item to persist across reboots and uses TCP beacons for control.

Types of DarkComet Processes

• Main Controller: The primary darkcomet.exe instance handling C2 communication
• Keylogger Module: Captures keystrokes and sends to C2
• Screengrab Module: Screenshots/posts to attacker
• File Manager: Access to local files and exfiltration
• Service/Startup: Persistence mechanism to start on boot
• Network Module: Handles C2 beacons and data transfer

Is darkcomet.exe Safe?

No, not safe DarkComet is a malicious RAT that can compromise privacy and control. It should be treated as malware unless you are analyzing it in a controlled, authorized environment.

Is darkcomet.exe a Virus or Malware?

The real darkcomet.exe is malware. It is not a legitimate system process. Malicious variants can masquerade as legitimate software, so verification is essential.

How to Tell if darkcomet.exe is Legitimate or Malware

1. File Location:: Look for: C:\ProgramData\DarkComet\darkcomet.exe or C:\Users\Public\Documents\DarkComet\darkcomet.exe. Other locations are suspicious.
2. Digital Signature:: Right-click the file → Properties → Digital Signatures. Should not show a trusted publisher; many variants lack a valid signature.
3. Resource Usage:: Unusual CPU spikes, irregular network activity, or long-running background processes are red flags.
4. Behavior:: Check for remote command and control activity, keystroke capture, or screen capture actions.

Why Is darkcomet.exe Running on My PC?

DarkComet is designed to grant an attacker remote access. It may run when a machine is infected, or when a controlled analysis environment is in place to study its behavior.

Reasons it's running:

• Active Infection: The RAT is actively connected to a C2 server and awaiting commands.
• Background Keylogging: The module runs in the background to capture keystrokes and secrets.
• Persistence: Startup entries or services ensure it restarts after reboot.
• Remote Control: Includes remote desktop or shell access to the infected host.
• Data Exfiltration: Screenshots, files, and credentials may be sent to the attacker.

Can I Disable or Remove darkcomet.exe?

Yes, you should remove it. If you suspect infection, isolate the system and remove the malware with reputable antivirus/EDR tools.

How to Stop darkcomet.exe

• End Active Sessions: Open Task Manager (Ctrl+Shift+Esc) and terminate darkcomet.exe and related modules
• Disconnect from Network: Disable network adapters or block outgoing connections to known C2 hosts
• Remove Startup Entries: Use Autoruns or MSConfig to remove startup entries associated with darkcomet
• Remove and Scan: Run an up-to-date antivirus/EDR scan to remove components
• System Integrity Check: After removal, verify system files with sfc /scannow and check for rootkits

Common Problems: DarkComet Symptoms

If a system is infected with DarkComet, you may notice unusual behavior and resource usage.

Common Causes & Solutions

• Persistent backdoor: Remove via trusted security tool, verify no persistence mechanism remains
• High CPU from keystroke capture: Terminate capture modules and disable unneeded features
• Unusual network activity: Block C2 traffic, inspect outbound connections and DNS requests
• Unauthorized remote connections: Review firewall rules and restrict RDP/remote access
• Stored credentials exfiltration: Change passwords, rotate tokens, and scan for credential dumping
• Malware persistence after reboot: Identify and remove startup items, services, tasks; run system restore
