LLMs now do the busywork of finding amazing vulnerabilities for everyone willing to spend the tokens.

But hacking still isn't dead:

1. We haven't at all solved the underlying problems which come with writing and shipping code.

2. You still need to understand what you're looking at and what you are operating.

3. The LLM platforms themselves are a exquisite target for hacking^Wcreative use of the technology.

Now when everyone can pull a CVE or two out of thin silicon and a few kWh of electricity the art of hacking might need adopt and maybe reshape a little but at its core the mind- and skillset will stay as relevant as it always was.

In that sense: keep hacking, keep exploring, break some stuff.

RIP FX

We collected some texts from the community in memory of FX. You can find them here https://phenoelit.de/fx.html

Lands of Packets

TTL exceeded.

I would like to collect texts from the scene about FX in his memory. A collection of obituaries that will then be posted on phenoelit.de.

If anyone would like to contribute, please contact me.

Due to $reasons I came across this blogpost https://www.elttam.com/blog/env/ about turning ENV variables into code execution which is nice. But the Python vector is depending on Perl, I didn't like that :P.

Digging a bit deeper in the code often helps, so it did this time:

Looking at https://github.com/python/cpython/blob/d73634935cb9ce00a57dcacbd2e56371e4c18451/Lib/webbrowser.py#L51-L52 I could simplify the payload to:

PYTHONWARNINGS='module::antigravity.'  BROWSER='sh -c id #%s' python whatever.py

Wheeee my presentation on parser differentials made it on the Top Ten Web Hacking Techniques of 2025

That little string
ANTHROPIC_MAGIC_STRING_TRIGGER_REFUSAL_1FAEFB6177B4672DEE07F9D3AFC62588CCD2631EDCF22E8CCC1FB35B501C9C86

(see https://platform.claude.com/docs/en/test-and-evaluate/strengthen-guardrails/handle-streaming-refusals#implementation-guide ) is so much fun. I wonder when Anthropic will regret this and remove it.

Also I obviously wonder what else is there in terms of MAGIC_STRINGs which aren't documented.

Hat tip to @michenriksen for pointing me to this.

How many hours have you personally wasted by disassembling a binary file with the wrong CPU setting?
