> Free offensive security knowledge base: pentest methodology per service and platform, CTF writeups, certification study paths, vulnerability research, advisories and small pentest tools. Every command uses placeholders such as $TARGET_IP and $LHOST.

Content is written for authorised testing, CTFs and learning. English lives on https://hackindex.io, translations under /nl, /es, /ru, /zh and /hi.
