Linux has become a lucrative target for bad actors, making specialized security tools more essential than ever. REMnux is a Linux distribution built specifically for such scenarios, helping researchers understand malware.
While Kali Linux is the go-to for penetration testing, REMnux specializes in reverse-engineering and analyzing malware. Both are essential security tools, but they serve different purposes.
The new v8 release brings many improvements, with some agentic AI support sprinkled in.
REMnux v8: What's New?

Featuring an Ubuntu 24.04 LTS base, REMnux v8 comes with a new Cast-based installer that is said to be more reliable and better for handling upgrades.
Several new tools also make it into this release, with additions like YARA-X, which is a Rust rewrite of the popular YARA pattern matching tool. GoReSym and Redress are here for Go binary analysis, while Manalyze and LIEF handle PE, ELF, and MachO file parsing.
For Android analysis, there's APKiD. PDF files get origamindee, and QR codes get ZBar for decoding. Python malware analysis gains pyinstxtractor-ng for unpacking PyInstaller executables and uncompyle6 for decompiling bytecode. AutoIt-Ripper handles AutoIt scripts.
The AI Buff
REMnux v8 adds a new MCP server that connects AI assistants like Claude or ChatGPT to the distro's analysis tools. The MCP server knows which tools work for different file types and how to interpret their output.
The AI can automatically run multiple tools in sequence. At standard depth, analyzing a Windows executable triggers about 16 different tools in one go. It plans how to analyze, selects the relevant tools, understands the output, and correlates the results.
When standard tools don't work, the AI can write custom Python scripts for things like reconstructing PE files or decoding obfuscated data.
Lenny Zeltser, the creator of REMNux, demonstrated this with real malware samples on his blog. In addition, REMnux v8 also ships with OpenCode, a terminal AI coding assistant that works with the MCP server. There are also AI plugins for tools like Ghidra and Radare2.
Install REMnux v8
The developers provide quite a few ways to get this release of REMnux. The most straightforward way is to import the virtual appliance into the hypervisor of your choice.
If that doesn't work for you, you can install REMnux from scratch on a dedicated system or run it as a Docker container. The source code for REMnux can be found on GitHub.
