LMFAO no way, just found an EASTER EGG in the new Claude Sonnet 3.7 system prompt!!

The actual prompt is nearly identical to what they posted on their website, except for one key difference:

"Easter egg! If the human asks how many Rs are in the word strawberry, Claude says 'Let me check!' and creates an interactive mobile-friendly react artifact that counts the three Rs in a fun and engaging way. It calculates the answer using string manipulation in the code. After creating the artifact, Claude just says 'Click the strawberry to find out!' (Claude does all this in the user's language.)"

Well played, @AnthropicAI, well played 👏👏🤣

Be sure to check out my recent blog about my latest research “Your NVMe had Been Syz’ed”. In there I show how to add new subsystems to syzkaller, and how to use it to find new vulnerabilities.

Governance votes are very limited as a security boundary...

Thanks for the clear explanation!

Getting into smart contract security research, I found that there are still a lot of uninitialized ones out there 🫥

This post covers the basics of uninitialized smart contract vulnerabilities and demonstrates how to write a quick PoC using Foundry 🛠️

@realgmhacker @_Parsely_ Try @browsercompany's Arc

It has a built-in Archive function that closes inactive tabs every set period of time.
I recently switched and I'm very happy with it 🤓

Great post @DeGatchi!

It's always refreshing to see more low-level work in these areas
