THE ENTIRE OFFSEC CURRICULUM JUST GOT REPACKAGED AS CLAUDE SKILLS.
OSCP costs $1,649. OSEP costs around $2,500. OSED costs another $2,500. SANS courses run $8,000 each. A Burp Suite Pro license is $475 a year. A senior pentester clears $180k.
A guy on the internet named Kai Aizen just put the methodology behind all of it into 58 SKILL.md files and pushed them to GitHub for free.
The pack is called claude-red. It primes Claude with expert-level offensive methodology across 13 categories the certification industry charges five figures to teach:
- Web app exploitation → 16 skills (the whole OWASP Top 10 and then some)
- Active Directory → Kerberoasting, ASREProast, ADCS ESC1 through ESC15, delegation abuse, NTLM relay, hybrid AAD pivots
- Wireless → WPA2/3 cracking, evil twin RADIUS, Dragonblood, KRACK, BLE, Zigbee, Z-Wave, LoRaWAN
- Cloud → AWS/Azure/GCP privesc, IMDS abuse, cross-account persistence
- Exploit dev → modern kernel mitigations, ROP, CFG/CET/PAC bypass theory
- EDR evasion → unhooking, indirect syscalls, PPID spoofing
- AI security → prompt injection, jailbreaks, RAG poisoning
Here's the part the cert industry doesn't want you to think about:
The actual methodology behind every OSCP-style course is publicly documented in OWASP guides, PortSwigger Academy, HackTricks, BloodHound docs, ADSecurity, the Shellcoder's Handbook, and a hundred Black Hat talks.
claude-red just organizes it into context-aware skills that load on demand inside Claude.
1,931 stars in three months. 314 forks. MIT license. 22 commits because the author dropped the whole library at once.
One honest note: this is for authorized red team work, bug bounty programs you're scoped for, and CTF prep. Hitting things you don't have permission to hit is a felony in most jurisdictions and no skill file will save you from that.
The five-figure certification industry just got a peer it didn't ask for.
