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.
