    Generally binary rewriters will add a new section for the rewritten code/other stuff that needs regeneration (relocations, exception info, the like)

    To add to this, the obfuscation used for their anticheat seems to be… kinda bad? Worse than Epic’s virtualizer/Griffin probably https://k0mkc.hatenablog.com/entry/2026/08/06/032440…

    back.engineering folks seem to imply that Denuvo is another case of virtualization based obfuscator being vulnerable to a symbolic execution/optimization approach. > As AI assisted…

    Out of idle curiosity: can NASM emit Windows unwind information? For the matter, can any assembler do so automatically?

    The service where Counter-Strike actually gets played competitively, FaceIT, does not work on Linux.

    Kinda offtopic, but I was somewhat surprised by Assembly having an “exclusive AI partner” this year.

    Sandboxie/WinFSP/KVM guest drivers for Windows are open source too I’m sure there are more open source examples. A newer one is https://github.com/namazso/PawnIO/tree/master I gues…

    If anti-cheats actively whitelisted drivers playing competitive video games would be impossible for people using any rarer HW/utilities. Vulnerable drivers are generally blackliste…

    Reversing for the most part, though lately I’ve been doing some code obfuscation/binary rewriting stuff. Fable will switch to Opus instantly on these and I’m unsure how this will p…

    5.6-Sol is a lot more permissive than Opus/Fable even w/ CVP (once you sign your soul away to Palantir via Persona, anyway), while maintaining better capabilities

    > Opus 5’s safeguards match those of Claude Fable 5’s, with one change: it now permits source-code vulnerability discovery at all access levels. This means that the model can suppo…

    Are the other Zero IT Lab products like their code virtualizer of similar quality to Theia? My only exposure has been that one RE//verse presentation and shitposts on UC.

    While the page decryption trick should work in Wine just fine (ZeroIT Lab Theia does that too, right?), I don’t remember if Wine provides workingset info like Windows.

    EAC is a kernel mode anti-cheat on Windows, though? And given the whining on UC it seems to be fairly effective.

    Wine doesn't provide every userspace facility Windows does.

    Do humans often repeat JSON spewed by integrations? It’s still very much a LLM.

    Given 5.6 and K3 I’m sure the window will be extended again. Have to maintain being somewhere on the frontier. Shame Fable is completely useless for me due to security classifiers.…

    They’d need to either poach folks from other firms or go for a third party solution. Cursed timeline: Valve pays Epic for good EAC build on CS2 + whatever encryption solution they …
