crackmon - Monitor hashcat / mdxfind crackrate

[A Former User]

What is it for?

@174region174

crackmon is a wrapper for hashcat that monitors cracking performance of the current attack session and sends a bypass command to hashcat if the crack rate falls below a defined threshold.
ex: if you want to bypass the current attack if hashcat hasn't cracked at least 100 hashes in the last 10 minutes, you can use crackmon to bypass the attack by using the command below:

./crackmon -t 10 -c 100 ./hashcat {hashcat args}

Any chance that this tool can be modified to support HashManager as well? Maybe by using a specific flag that will be used when running Hashcat, and when using HashManager... if this last one can be supported.

[v1cvap0r]

Oh, forgot: and mdxfind ? Any chance ?

@v1cvap0r
That's a neat idea. Feel free to submit an issue on github to request support for HashManger and/or mdxfind. If there's enough interest, I'll look into either adding support or developing a separate tool for them.

Do keep in mind, crackmon is specifically written to read hashcat's status and send control commands back to hashcat, like pressing "b" to bypass the current attack. Not much of the existing logic would work with HashManager or mdxfind, so supporting these tools would require a significant rewrite of crackmon’s codebase.

Update 2025/11/17
Support for mdxfind added

[v1cvap0r]

It's now done.

Another sugestion/request: can be added and option to on/off a beep sound when a hash is cracked? This is useful for (very) long runs and people are away from the computer, in the same or a continuous room. The beep sound will call our attention for something that has been found.
This obviously will be turned off or simply not included in the command line, when running lists with continuous founds.
Maybe there are other solutions that I'm not aware off.

@v1cvap0r While that could be done, crackmon was designed to bypass the current hashcat attack when the crack rate falls below a defined threshold. To be notified of new founds, there's other solutions such as monitoring hashcat's potfile and/or output path. This method is something I've written tools for myself and clients and can be set to play a sound, display a notification, send an email, etc.

Adding support for mdxfind has been requested by several users. I am pleased to announce that PR#11 adds support for mdxfind for both Linux and Windows.

./crackmon -c 10 -t 5 ./mdxfind -m 0 -f hashes.txt hashpwn.txt

@v1cvap0r I use an ANS (Automated Notification System) for this purpose. It uses the Python Watchdog module. After startup, it continuously monitors the contents of the hashcat.potfile and the john.pot file.

Startup message: ️ Warning. Recovery process has been started. ANS (Automated Notification System) has been activated!

It continuously monitors for changes and optionally sends them either via email or as a push message to a Signal or Telegram address. The script requests this data after startup.

I also created a service file for playing the sound file. It also uses Watchdog to continuously monitor the contents of the potfiles and plays the sound file I selected.
