Timeline: 43:30 Programming The Windows Driver Model by Walter Oney and Windows Kernel Programming by Pavel Yosifovich warned against touching the IRP after calling IoCompleteRequest(). Did you take that into consideration? I noticed that you touched the IRP after calling IoCompleteRequest() by following with return irp->IoStatus.Status. They pointed out that it could lead to system crash.

@@timnonik2736 Yes, I am very serious. This is the most common, easiest, most plastered source/PoC of 'bypassing' an anti-virus / anti-cheat in the world. If you don't actually understand how it works, you will achieve and learn nothing. And saying it's "self-written" is a fucking joke. Typing it out on your own doesn't make it self-written.

[@chavo6613]

Thank you so much Cazz for sharing all your knowledge with us man 🔥

[@hooliganez]

After "bcdedit /debug on" and rebooting, things can start going crazy. Slow boot, freezes time-to-time. As far as I have read - this is UEFI/BIOS nuances. bcdedit can be slower on UEFI systems due to synchronization between NVRAM (which holds UEFI boot variables) and the BCD (Boot Configuration Data) stored in the registry. If anybody faces this - do not freak out. Just disable kernel debugging. Things should go back to normal 💪

Great Video as always. Where did you learn stuff like that anyway?

[@inqmusician2]

MS devs back in the day didn't call the blue screen "blue screen of death". They call it simply blue screen or a BugCheck. BugCheck(or KeBugCheck) is a function down in the NT API that allows to raise the blue screen in the event that something down in the kernel. I'm here mostly for malware development, because the knowledge between cheat development and malware development is interchangeable. Like creating drivers and making malware that is invisible to the antiviurs or an IDS program. Or bypasssing anticheats, that are behaving like antiviruses themselves. The more you live, the more you learn.

could you do a part 2 on this for injecting a DLL into a process from the kernel driver?

Could you do a video on either MmMapIo Managing / Usage or creating a loader/mapper tool for the drivers like say using a DSE Bypass to load a driver over NtLoad and then using that driver to map the other driver into kernel space with a pre-defined object and then calling the OEP and starting a thread out of the mapping driver to bypass Ps Module Lists in the NTOSKRNL Structs? I've been studying this and a lot of other people do too so it would be cool.

[@RENNE44]

And maybe using other driver communication methods like encrypted post-server kSockets or HW Paging BP with register spoofing to interpret calls in the kernel using a custom dispatch in the PE of the usermode program? Maybe even try teaching people more about NTOSKRNL, EPROCESS, Ps, PEB/TEB, Etc?

34:57, that's NOT what a pid (process id) is, that is a handle to a potentially zombified process. A pid is a DWORD and it is possible for it to change which process it references if the referenced process closes between getting that pid and using it to try and open said process. For the sake of others reading this, it is however correct to use the HANDLE since there's only one process it can refer to while the handle is open, unlike the pid which is only useful when you've yet to open a process handle. Once the handle is open you're supposed to verify the handle is to the process you intended (excluding situations where the user is directly involved like Cheat Engine) just in case the process you intended closed and new one took over the pid you had found.

[@cazz]

Thank you for the clarification! EDIT: After reading the MSDN documentation of the PsLookupProcessByProcessId, it clearly states that the parameter is a process Id, despite it being of type HANDLE. In usermode HANDLE is usually used as an opaque data structure, yes, but kernel functions seem to have a different take on HANDLE. The comment below is actually correct. devblogs.microsoft.com/oldnewthing/20080228-00/?p=23283#:~:text=Process%20and%20thread%20IDs%20are,are%20process%20and%20thread%20IDs.

wrong, it's the process ID. they're stored as HANDLE values in kernel mode because pids are always multiples of 4 as handles are

​@@zxuijii don't think you understand what handles are or how they work, your original comment makes no sense. also, why are you bringing up openprocess? this is kernelmode. "handle to a potentially zombified process" is really stupid as well, just creating an instance of an object that is of type HANDLE doesn't open a handle to anything, since HANDLE is just a typedef void* as they're are meant to be opaque
