Part 1 of my #BGGP6 writeup about nasm's most mysterious object file format, RDOFF. n0.lol/bggp6-rdoff/

Today I got RDOFF (.rdf) files working in nasm 2.15. I wrote my own lib bc nasm didn't generate properly. Also patched the 32-bit loader in `rdx` with mmap tricks (shoutout ixi). An executable RDOFF has likely never run on a 64 bit system before today. Writeup soon! #BGGP6

The easiest way to not include all the link tracking stuff in links you send is to just type a space before the first ? in the url.

Then for bonus points just delete all the junk after the ? and wow, your link is normal again. At the very least, all the tracking junk doesnt get auto rendered if you do the space before ? trick.

Arbitrary code execution in objdump -g We have a thing for finding bugs in bug finding tools. IDA Pro, Ghidra, Binja Sidekick, or radare2. You name it we hacked it. Our friends were saying we should try objdump. So here we go. Blog post: blog.calif.io/p/oobdump-relo… AI-generated PoC and writeup: github.com/califio/publicati…

This is how boomers did debugging :D, this shows loading the ring0 softice tool on windows 2000, setting some style options, then setting a system wide API breaking point and following a stack string decryption

I've never written a binja architecture plugin before, but I gotta say, I would not recommend your first one being a cursed MIPS extension

yesterday @b1ack0wl nerd sniped me into this, it's been a lot of fun, but my god, it's not so easy to generalize instruction formats, since instructions randomly have little curve balls depending on the context

When working with computers we frequently find these cool little tidbits/tricks/tips we could share. They are too small to make a full article, but they are likely the right size for Paged Out! magazine, where each article is just 1 page 😎 CFP deadline for Issue #9: 30th April
