OpenAI had some of the friendliest and most capable triagers I’ve worked with but their bounty tables are insulting 😅
Replying to @S1r1u5_
We reported the bug to Discourse and OpenAI. OpenAI fixed the SSO issue roughly 14 hours after our initial submission.
Discourse received our separate report Saturday, replied Sunday, and had a fix Monday.
OpenAI awarded us $6,500.

We’re disclosing HEIF Heist, a months-long investigation into libheif that allowed us to hack OpenAI, Slack, Meta, GitHub Ent, Rails, Next.js, ImageMagick, and many more.
It was literally xkcd #234, one obscure image library beneath a huge number of apps. 🧵

I’ve changed my mind on how dangerous AI can be for humanity.

Whoever uses AI as their personal therapist better has solid security controls on their account.
We're not ready for GPT-account hijacks.

how i hacked 320+ companies that replaced their cs team with "smart" ai agents:
1. drafted a gdpr request to support@
2. changed the FROM header from my e-mail to yours (spoofing)
3. put myself in CC
4. ai agent responds with YOUR data to BOTH of us 😈

Most support chatbots have evolved into fully autonomous agents that can help you with almost anything... And that comes with additional risk ☝️
Our latest article, based on @intidc's talk at Bug Bounty Village during DEF CON 34, breaks down the full attack surface in AI customer service agents, from tricking them into leaking sensitive data via email spoofing to invoking unauthorized tool calls on behalf of the victim. All without ever touching any automated scanner or proxy interceptor! 🤠

Update, deze vond ik van een begeleidster van een andere school uit Buggenhout ook verstopt in de Facebook reviews. Zelfde chauffeur of niet, feit dat firma niet reageert…
E-mail server van dit management zo snel mogelijk in beslag nemen a.u.b. 🙏
Geen idee of dit reeds gepost is, maar ik vond deze Google review van 2 maand geleden over de busmaatschappij die betrokken was bij het vreselijke ongeval in #buggenhout. 🤯

Je zal maar een hardwerkende cybercrimineel zijn, om dan mensen zoals @intidc tegen te komen die het allemaal verpesten.

An excellent example why you should never enter your credit details into kiosk screens! Hackers can replace the screen with a fake order app in seconds... or with an entertaining music clip for all customers to enjoy! 🕺🎶
