Inquiry About the Best Free Remote Administration Tools (RATs) - SSR771 - Apr 25, 2025

Hello,

I'm currently using njRAT Danger Edition as my primary remote administration tool. However, I've encountered a consistent issue: targets are required to install the .NET Framework, which complicates deployment and user interaction.

I'm looking for recommendations on free RATs that meet the following criteria:

Do not require the target to install additional frameworks (or have a more seamless deployment).
Offer features similar to VenomRAT (such as remote desktop, keylogging, file management, and persistence).
Allow for the use of a dynamic hostname or link (e.g., DuckDNS or Pastebin) in the host field, rather than requiring a static IP address.
If VenomRAT itself can be configured to support dynamic hostnames via a link or raw URL, I’d appreciate a walkthrough or clarification on that as well.

Thank you in advance for your help.

1. Free RATs with no dependency on the .NET Framework:

Quasar RAT (Open-Source):
  • Download the source code from GitHub

  • Build the client using Visual Studio (select the “No Framework Dependency” setting).

  • Set up a server on a VPS or hosting with DuckDNS.



AsyncRAT (Open-Source, C# but with dependency bypass):
  • Download the latest version

  • Use ILMerge to embed .NET libraries into a single executable.

  • Set up a dynamic host via Pastebin (automatic link update).



DarkComet (Legacy, but lightweight):
  • Download a clean version (no backdoors).

  • Use the built-in No-IP/DNS client for dynamic addresses.

  • Disable .NET checks in server settings.



2. Configuring VenomRAT for dynamic hosts:

Via Pastebin/DuckDNS:
  • Create a script (Python/PHP) that updates Pastebin with the current IP of your server.

  • In VenomRAT, specify the raw URL in the host field.

  • Configure the client to periodically check this link.



An alternative is Ngrok/Cloudflare Tunnels:
  • Sign up for Ngrok, get an auto-updated subdomain.

  • In VenomRAT, type subdomain.ngrok.io instead of IP.

  • For persistence, use Ngrok's hidden mode (TCP tunnel).
