i am subscribing to misery, i think. anthropic posted a new bug bounty today, on hackerone, and i had to buy claude code for work, and i applied to their 'cyber program' (and got access in ten minutes?! wow - i submitted to openais cyber cyber thing a week and some change ago and havent heard anything back. radio silence) so i figured, aim mythos or whatever right back at anthropic, and i think i found a bug. an interesting one too. i submit it and am FULLY expecting to be pissed later.

If it is a corpo : immediate disclosure is responsible disclosure. Or less professionally 'fuckem' it takes me longer to get in touch with someone from ur team then it took to find the vulnerabilities.

wtf.
i can send whatever i want directly at your staff in a secure way and thats 'informational'?

I'm eagerly awaiting adding malicious content into RSS feeds that are `/feed` imported into Slack so that Slack's AI get's pwnd six ways from Sunday.

Pastebin.com is the number one paste tool since 2002. Pastebin is a website where you can store text online for a set period of time.

Pastebin (pastebin.com)

so have a look at that - its the claude code tui wrapper system instructions that apply to any 'security review' anybody asks claude to do.

review that file and tell me if you think claude is still a good tool to aim at code that needs a security review.

Anthropic's own safeguards are "ask the LLM not to do something", but we know asking LLMs not to do something isn't a guarantee they will not do that thing (deleted emails, deleted production databases, etc).

Isn't that fundamentally kind of... fucked? Like the burden is then on users to make the system safe with controls external to the LLM because the vendor can't make it safe themselves?

It actually called it out as a "prompt injection attempt" for me to look into.
