|
|
Hi, i want to know how to bypass the memory integrity check.
The hack i'm trying to use is a sort of speedhack that makes me spam skills faster. When i use it inside the game everything works perfect for 3-4 seconds, then game closes itself and give me this error:
Memory Integrity Test Failed:0
Is there a way to bypass that?
Thank you. |

In most cases, memory integrity checks like this are doing one of two things:
1. Taking a snapshot of a games static memory (basically whatever is loaded directly from the exe and not allocated memory) and comparing it to what is currently live in memory. If the live copy of memory does not match the original, it will trigger the error and crash the game.
2. Uses the original binary to compare its code section to the live memory. Same as above afterward.
These are generally either done as a byte-by-byte compare, or a checksum of the memory regions. Bypassing these usually consists of either:
1. Overriding the locations the game is checking against and making it check against the same region that is modified.
2. Altering the end result CRC/hash that the game expects to match your newly edited memory's CRC/hash.
3. Hooking the function and just always returning the expected value regardless of what is being done.
In some cases, and in poorly designed checks, you can block the memory reading altogether with an invalid access return and the protection will just assume that if it can read it, nothing else could either so it should be fine. _________________

ehm, i never thought of changing permissions.
that can be very interesting, but can CE do that?
i know we can remove memory protection to get full access (read/write and execute) but changing permissions to write only or read only i dont know.
anyway, this is a light for me so thanks for that light atttttooooomm. _________________

Oh nice, thank you. Is there a post, guide, or something i can read somewhere to learn how to do this? |

Not really, most anti-cheat discussions are done in private and not public anywhere to prevent things from being fixed/patched. _________________
