Penglab : Abuse Of Google Colab For Cracking Hashes

Penglab is a ready-to-install setup on Google Colab for cracking hashes with an incredible power, really useful for CTFs. 

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.

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.
