That was fun. I bypassed a @OpenAI ChatGPT /mnt/data restriction via a symlink, downloaded envs, Jupyter kernels' keys, and some source code from there. Reported via @Bugcrowd and got not applicable! Now this issue is fixed (in like an hours after my report).. Is it how it should be? Asking for the community here. Screenshots attached.

How do you fuzz code that cannot be instrumented, e.g. on an embedded system? It turns out you can use GDB for that!
👉 Check out our upcoming “GDBFuzz” @issta_conf paper at publications.cispa.saarland/…
👉 GDBFuzz is available as open source at github.com/boschresearch/gdb…
Happy to announce that our paper "Fuzzing Embedded Systems using Debug Interfaces" is accepted at #ISSTA2023 ! In the paper, we present our debugger-driven fuzzer GDBFuzz , which leverages hardware breakpoints to gain coverage feedback.

Need to bypass the JWT signature? Kid param injection + directory traversal = signature bypass
Vulnerable apps using 'kid' for key retrieval might allow attackers to force a predictable key file (e.g. static file or /dev/null)🔓 Crafted malicious tokens signed w/ known key

chatgpt-4 has reach human level! I asked it to create a C++20 example using modules with a makefile and it didn't work. I also can't get it to work. Amazing!

What is the mental model of a hacker?
Timothy C. Summers, Ph.D., studied "the structure and content of the mental models used by hackers and to what extent different factors are instrumental in shaping the acquisition, maintenance, and use of mental models critical for hacking."

The new cs.github.com search allows for regex, which means brand **new** regex GitHub Dorks are possible!
Eg, find SSH and FTP passwords via connection strings with:
/ssh:\/\/.*:.*@.*target\.com/
/ftp:\/\/.*:.*@.*target\.com/
I couldn't find the author

Ukraine is risking WW3 by shooting down an innocent Russian cruise missile on its way to denazify a childrens playground.
