This esp32 "bluetooth backdoor" doesn't sound very different from what @naehrdine.bsky.social + crew found in bcm43xx to develop github.com/seemoo-lab/i...

I got Linux running in a PDF file using a RISC-V emulator.

PDFs support Javascript, so Emscripten is used to compile the TinyEMU emulator to asm.js, which runs in the PDF. It boots in about 30 seconds and emulates a riscv32 buildroot system.

Looking at this list of 2023 routinely exploited issues It's always interesting to look at the split between memory safety issues and bug classes. https://www.cisa.gov/news-events/cybersecurity-advisories/aa24-317a

Gotcha, yeah, definitely not a hermetic build :)

Is it actually building malware.rs or is it just retrieving the contents of a text file? Sorry, I don't know rust but it seems to be the latter?

You can do some magical things with paths on Windows. If you haven’t seen it before JonasLyk’s work on β€œwebdav based reflective loader/per process devicemap based dll injector POC” is a work
of art. Search his handle + webdav on X for some commentary

Inside a Firewall Vendor's 5-Year War With the Chinese Hackers Hijacking Its Devices Sophos went so far as to plant surveillance β€œimplants” on its own devices to catch the hackers at workβ€”and in doing so, revealed a glimpse into China's R&D pipeline of intrusion techniques.
