Looking into a potential SSRF or OR but the server checks against a URL whitelist?

Try the backslash trick! Due to a difference in URL specifications, some parsers will treat '\' the same as '/', while others will not.

Here's an example payload: https://<attacker-url>\@<whitelisted-url>/

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.

If you found a dangling DNS record, you might be able to take control of it 👀

Be sure to check https://github.com/EdOverflow/can-i-take-over-xyz, which has an extensive list of vulnerable services and guides on how to claim them.

Modern websites use a lot of intermediary servers - caches, load balancers, proxies, and so on. You can try to send the 'Max-Forwards' header with your request to limit the amount of servers it will reach. It's defined in HTTP specs primarily for TRACE and OPTIONS methods, though.

Recon tip: Run xnl-h4ck3r's waymore on the target you're testing. It searches for URLs from multiple sources, the Wayback Machine, Common Crawl, URLScan and more. It also provides a lot of options to filter your results.

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!
