Hot take: most GenAI solutions are taking data you had and piping it to some major LLM for analysis, and getting back a mixed bag of ok & terrible results. Instead of working, you work harder to validate LLMs (and pay for it). It's another layer of chaos, mislabeling and noise to struggle through.

Ori Ron and I found a cool way to attack the HITL, by convincing it to inject content and markup right after commands. Anyone would press Yes if the attackers control the question.

So this might be a stupid question but - if #LLMs that feed themselves ruin their own datasets, wouldn't inbreeding of a several LLMs feeding one another also inevitably result in the same? Wouldn't an LLM-heavy internet inevitably still become a sort of inbred LLM amalgamation meta-model/dataset?

We did a thing with Claude Code checkmarx.com/zero-post/by...
It's very cool, but using it to gate automated security code reviews is very, very dangerous

Want to see a free, #OpenSource, developer-friendly tool for preventing secrets leaks? Checkmarx Zero's Tal Folkman will be on-site BlackHat #Arsenal (#BHUSA) to demo Too Many Secrets (2MS), available from buff.ly/Yng76l5

Mark your calendar! 2pm (local time) on 6th August, at Arsenal Station 5

#CVE-2025-6514 being 9.6 is a bit bullshit. It's kinda cool, but I'm sorry - if you connect with #MCP, a protocol for running code, to an untrusted MCP server, and it runs code - it's a footgun, not an RCE. The exploit itself is very interesting though.

#TACO? Surely you mean Wrap of America.

My condolences to the United States for having lost the Cold War.

And finally part 4 of 4 of my @hf.co security research - bypassing poorly designed model scanners multiple times to smuggle malicious code because the detection mechanism pattern rhymes with "chitty glocklist" 🤷🏼

Part 3 of 4 of the Hugging Face security research - so many model-loading HF integrated libs are vulnerable to code execution, but it's all an open secret that no one will fix

Aaaand here's part 2 of my horrible Hugging Face blog, it's a deeper dive into code execution in protocols used by open source LLM frameworks

So I found a ton of interesting crap on Hugging Face, some of it known and some of it less so. Started a 4 part blog about it.
Here's part 1, about configuration and excessive trust in ReadMe files

How fortunate, I closed my Twitter account two weeks ago and hey what do we have here? Hope this one catches, Apartheid Karen can eat ass.
