Penglab – Abuse Of Google Colab For Cracking Hashes
Abuse of Google Colab for fun and profit.
What is it ?
Penglab is a ready-to-install setup on Google Colab for cracking hashes with an incredible power, really useful for CTFs. (See benchmarks below.)
It installs by default :
- Hashcat
- John
- Hydra
- SSH (with ngrok)
And now, it can also :
- Launch an integrated shell
- Download the wordlists Rockyou and HashesOrg2019 quickly !
You only need a Google Account to use Google Colab, and to use ngrok for SSH (optional).
How to use it ?
- Go on : https://colab.research.google.com/github/mxrch/penglab/blob/master/penglab.ipynb
- Select “Runtime“, “Change runtime type“, and set “Hardware accelerator” to GPU.
- Change the config by setting “True” at tools you want to install.
- Select “Runtime” and “Run all” !
What is Google Colab ?
Google Colab is a free cloud service, based on Jupyter Notebooks for machine-learning education and research. It provides a runtime fully configured for deep learning and free-of-charge access to a robust GPU.
