When testing GraphQL APIs make sure to run graphw00f (https://github.com/dolevf/graphw00f) to fingerprint the specific GraphQL implementation the application is running. Then you can review the Threat Matrix to get likely attack vectors.

If you found a package.json file in the wild, you might find some internal packages vulnerable to a dependency confusion attack 👀

Check for it quicker using this cool new tool by JSMon: https://app.jsmon.sh/tools/npm-validator 👇

Tomorrow I'll be speaking at https://lisbonai.xyz

We're building faster than ever with AI. But are we building securely?

I'll show how agents can perform penetration testing and introduce Hackian: an autonomous agent that identifies vulnerabilities before attackers do.

Thanks @hacker0x01.bsky.social for the amazing LHE!

Had the chance to work with TikTok and OKX and found some cool vulns, including two 0days. Will try to publish a write up once they're fixed!

Also, big congrats to the new MVH champion @corraldev.bsky.social for the huge mic-drop at this event 🤯

If you need a list of trusted resolvers, e.g. to be used with puredns for active enumeration, @trick3st has a great one.

Just run this: 
⌨️ curl https://raw.githubusercontent.com/trickest/resolvers/refs/heads/main/resolvers-trusted.txt -O

If you look at the AI-generated code below, you may notice that path traversal is prevented via basename functions.

Can you still exploit it?

This one-liner by @tomnomnom.com finds all Git repos, creates a git-objects/ folder for each one and dumps every object (commits, trees, blobs, tags) into files named by their hash.

Effectively exporting the raw Git database into human-readable files, repo by repo!

And that's a wrap 🎰

First time with @ethiack.com at #hackersummercamp

This year I didn't participate in any Live Hacking Events, so I pivoted to the OSINT competition from Recon Village. I'm now an uncertified geoguesser📍

See y'all next year!
