As long as you can read and write to memory, you will never stop online cheating in FPS games.
If I put a hardware connection to the memory (basically WIRES to my memory bus) then yes, it's very hard to detect. But that's also very hard and expensive to do...

So....yes. But there are mitigating tactics around this, I really recommend looking into it because it's a fascinating topic. As the simplest thing - you don't ban cheaters the moment they are detected to not give off how you detected them. That's why Activision bans people in waves and all at once, even though they know some people are cheating and still active. Unfortunately a lot of people are paying for cheats nowadays, and the cheat makers usually have some kind of refund policy where if you get detected you get your money back - games companies want to inconvenience those buyers as much as possible, so you can't claim your refund straight away because hey, the game worked for a good while even while you were cheating, must have been something else :P
>>Meanwhile the normal user is both confused and significantly more inconvenienced
Yes, which is why the aim is to have 0 legitimate players getting caught by this, obviously.

An additional benefit is that this can include multiple cheat programs and versions in one ban wave, so it may be harder to narrow down exactly what the flaw was. That's the why for no warnings (or explanations) - false positives and recourse if mistakenly flagged is another matter entirely.
Needs to be a law against the taking away of product functionality after the sale, even if it's contractual/EULA. A ban should never take the game away from the owner, and in cases where it does then they need to be refunded (treble damages on top of license, lawyer, and court fees if it takes a judgment to induce the refund). Getting banned on Steam, say, in the sense that all of one's purchases are invalidated shou…
And it's just a game that's not playable anymore, not the whole Steam account, isn't it?

Other players paid too.
I'm very curious about the jump obfuscation. Maybe somebody who's done more reverse-engineering can answer this for me: a) Are unconditional jumps common enough that they couldn't be filtered out with some set of pre-conditions? b) It seems like finding the end of a function would be easy, because there's a return. Is there some way to analyze the stack so that you know where a function is returning to, then look for…
Few common issues. 1. Some jumps will be fake. 2. Some jumps will be inside an instruction. Decompilers can't handle two instructions are same location. (Like jmp 0x1234), you skip the jmp op, and assume 0x1234 is a valid instruction. 3. Stack will be fucked up in a branch, but is intentional to cause an exception. So you can either nop an instruction like lea RAX, [rsp + 0x99999999999] to fix decompilation, but then…
Cheating in multiplayer games has become such a huge problem, it has destroyed trust across every major FPS. I am a long time CS player, but I did briefly play one of the new CoD games, before they went crazy with Nicki Minaj skins and bong-guns. A person was so convinced I was cheating, they started doing OSINT on me while still in a match, and they found my old UnKnOwNcHeAtS account as some kind of proof that I am…
fwiw, cheating in CS(GO) taught me x86 RE and low-level programming way younger than is usual. sophomore year of high school. I still recommend writing an HvH cheat to anyone that wants to get into proggin' -- you get a taste of both static and dynamic RE, memory-level programming, UI development, bare dxsdk (usually), a skid-saturated environment, sysadmin (if you try to set yourself up an uber1337 cheat page), and…
though personally I can't be that mad if you wrote cheats yourself, I will be a bit angry but impressed too ;)

Would you not have to use a jump instead of call for it to be a tail call at all- ie otherwise a new frame is created on each call
the call is still in tail position whether or not it reuses the stack frame. there are also more involved ways to do tail call optimization than a direct single-jump compilation when you leave ret behind entirely, such as in forth-style threaded interpreters
I’ll do some reading on the latter part of your post, thank you!
