Colabcat is a tool used to run hashcat on Google colab with session backup and restore.

colabcat.ipynbfile in Google Colab: https://colab.research.google.com/github/someshkar/colabcat/blob/master/colabcat.ipynb
- Click on
Change runtime type, and set
Hardware acceleratorto GPU.
- Go to your Google Drive and create a directory called
dothashcat, with a
hashessubdirectory where you can store hashes.
- Come back to Google Colab, click on
- When it asks for a Google Drive token, go to the link it provides and authenticate with your Google Account to get the token.
- You can edit the last few cells in the notebook to customize the wordlists it downloads and the type of hash it cracks. A full list of these can be found here.
- If needed, simply type
!bashin a new cell to get access to an interactive shell on the Google Colab instance.
How it works?
Colabcat creates a symbolic link between the
dothashcat folder in your Google Drive and the
/root/.hashcat folder on the Google Colab session.
This enables seamless session restore even if your Google Colab gets disconnected or you hit the time limit for a single session, by syncing the
.log and the
.potfile files across Google Colab sessions by storing them in your Google Drive.
