Memory.Manipulation

Library for memory manipulating, get regions, set rights, use pattern scan, calculate offsets, validate pointers and etc

Get regions

Mem.GetAllRegions()// All regions, even free
Mem.GetRegions(mbi => ...)// Regions adopting the condition in the argumentsMem.GetAccesibleRegions()// Commited regions without Guard that has access flags
Mem.GetCommitedRegions()// All Commited regions
Mem.GetReadableRegions()// Regions available for reading
Mem.GetWriteableRegions()// Regions available for writing

Create pattern for signature scan

Mem.CreatePattern("0 2F 90 ?")// 00 2F 90 ??
Mem.CreatePattern("0 0x2F 90 ?????")// 00 2F 90 ??
Mem.CreatePattern("00 2F 90 .")// 00 2F 90 ??
Mem.CreatePattern(2d)// 40 00 00 00 00 00 00 00// So work for all primitive types
Mem.CreatePattern([0,0x2F,0x90,null])// 00 2F 90 ??

Signature scan

varregions= ...;varpattern= ...;varfound=Mem.Scan(pattern,regions);

Pointer validating

varpointer= ...;varisValid=Mem.IsValid(pointer);// Checks if the pointer is inside the commited region

Calculate offsets

varpointer= ...;varshifted=Mem.CalcOffsets(pointer,0,8,0x90,0);/* Alternative for: var shifted = *(nint*)(*(nint*)(*(nint*)(*(nint*)(pointer + 0) + 8) + 0x90) + 0);*/
