  • Ah, so they don’t actually say that they read kernel space. They check the version of all installed packages and checksum the installed DLLs/SOs.

    If the user still has root privileges, this may still not prevent sideloading of kernel modules. Even if it would detect a kernel module that has been sideloaded, I believe it’s possible to write a kernel module that will still be resident after you unload it. This kernel module can then basically do anything without the knowledge of userspace. It could for example easily replace any code running in userspace, and their anticheat would miss that as it doesn’t actually check what code is currently running. Most simply, code could be injected that skips the anticheat.

    Of course, in their model, if a user isn’t given root privileges it seems much harder to do anything, then probably the first thing you’d want to look for is a privilege escalation attack to obtain root privileges. This might not be that hard if they for example run Xorg as it isn’t known to be the most secure - there’s a reason there’s a strong recommendation to not run any graphical UI on servers.

    Another way if you don’t have root is to simply run the code on a system that does but that does have such a kernel module - or perhaps modify the binary itself to skip the anticheat. I don’t see anything preventing that in their scheme.


  • I’m having a hard time understanding how this would work. udev will load kernel modules depending on your hardware, and these modules run in kernel space. Is there an assumption that a kernel module can’t cheat? Or do they have a checksum for each possible kernel module that can be loaded?

    Also, how do they read the kernel space code? Userspace can’t do this afaik. Do they load a custom kernel module to do this? Who says it can’t just be replaced with a module that returns the “right” checksum?












  • Yes, to be specific, according to the Quran women can wear whatever in the presence of “mahram” (close relatives), meaning, parents, grandparents, kids and grandkids iirc.

    In Iran, the mahram part is rarely enforced so in practice women can wear whatever inside private homes, no matter the relationship to those present.

    Recently, women in Iran are pushing back against the Islamic clothing rules in public and step by step bending the rules. Now, what you actually need to wear vary wildly depending on exactly where in Iran you happen to be. In some parts, typically rich parts of bigger cities, it’s in practice tolerated to wear almost western-style clothing at the moment.

    I’m tired of this kind of post, as it shows what a minority of society did in the 70’s, it also simplifies women rights issues in Iran to simply clothing. Although it is a prominent part, there’s much more to it. Things like that in court, a male witness is worth two female witnesses, and men inherit twice as much as women. Rape and sexual harassment is considered the fault of the women for dressing immodestly.
