My 7 year journey at HackerOne recently came to a close🏁 It's been an incredible run working with the best people and being part of something that transformed the security industry. Working there gave me a unique vantage point: the intersection of the world's best security…
Excited to be part of #HackAIcon. Great lineup - lots to discuss with AI reshaping everything we thought we knew about security

Just guy next to me at the gym explaining to his friend that before Hitler went for it, Jews boycotted Germany "just like we boycott Israel" and something something Rothschild controls all finances. Good work @BBCNews et al for the constant stream of blood libels setting the tone
Here’s the second half of our Friday lineup at @defcon – and it’s just as stacked. 🔥 @DaneSherrets, @Shlibness, @mgianarakis, Jordan Macey, @CryptoGangsta, @scriptingxss, @nytr0gen_, @erbbysam, and @BrunoModificato. See you there. 👀 #BugBounty
Hyped!!
🔥Get signing up. It's a neat curation!
Legendary work from @Arl_rose
Such a joy talking comprehensive asset discovery! Meeting the amass creator felt full circle - that tool's power to reveal overlooked and obscure subdomains is what kicked off my asset reconnaissance obsession years back and I've never looked back.

Looks like heathrowdropoffcharge.co.uk has been operating since February, gouging an extra £4 from circa 83,000 travelers by charging £10 for Heathrow's actual £6 drop-off fee. Just casual predatory behaviour that I suppose isn't illegal...
For the past few months I've been talking a lot of Software Supply Chain security and Depi ... Depi is SaaS platform aimed to find ways to backdoor the Software Supply Chain Security of the target we scan 🔥 Here it is ! The full story on how we built Depi and its philosophy 😁…
We just released a new article on how we made 50,000$ in #BugBounty by doing a really cool Software Supply Chain Attack🔥 🔗Link: landh.tech/blog/20250211-…
Working on exploiting a SSRF where the service is using axios. Looking at GH issues shows a PR that would have been perfect, allowing for local file read github.com/axios/axios/pu… Reviewing the profile of this "helpful" PR [that was never merged] shows some suspicious biases 😂
