Patching:

The patching functions will write to memory.
NOTE: When VirtualProtectEx() is used a PAGE_GUARD gets triggered. If you need more stealth you will have to come up with your own method until I implement one.

• Patch(): Writes given bytes to given address.
  • This function doesn't return anything.
  • hProc is a handle to a process.
  • dst is an address in the target process to write to.
  • bytes is data to be written by the function.
  • size is how many bytes to write.
• Nop(): Writes a specified number of NOP instructions at the given address.
  • This function doesn't return anything.
  • hProc is a handle to a process.
  • dst is an address in the target process to write to.
  • size is how many bytes/NOPs to write. (One NOP is one byte).

Process:

The process functions are used to gather information about processes, modules, etc.

• GetProcID(): Retrieve an ID of a process given its name.
  • This function returns a DWORD containing a process ID.
  • procName is a name of a process.
• GetModule(): Retrieve a module given a process ID and the name of a module.
  • This function returns a MODULEENTRY32 structure.
  • procID is a process ID.
  • modName is a name of a module.

Pattern Scanning:

The pattern scanning functions are used to scan for patterns within a process. Question marks in a mask will account for changes in a binary such as hard-coded addresses determined at runtime.

• PatternScanModule(): Scans for a given pattern with given mask inside of a given module.
  • This function returns a void pointer (void*) which contains the address where a pattern was found.
  • hProc is a handle to a process.
  • procName is a name of a process.
  • module is a name of a module.
  • pattern is a pattern to be searched for.
  • mask is a mask for a pattern.
• PatternScanProcess(): Scans for a given patter with a given mask in a given process passed via a process handle.
  • hProc is a handle to a process.
  • begin is a starting address of a region in memory to be scanned.
  • end is an ending address of a region in memory to be scanned.
  • pattern is a pattern to be searched for.
  • mask is a mask for the pattern.
• PatternScan(): Scans given bytes for a given pattern. This is used by PatternScanProcess() and PatternScanModule() which pass a chunk of memory to this funciton to be scanned.
  • base contains a pointer to bytes to be scanned.
  • size is a size of a buffer to be scanned.
  • pattern is a pattern to be searched for.
  • mask is a mask for the pattern.

Auto:

The auto functions are wrappers for common tasks so you don't have to write everything yourself constantly.

• AutoWriteToAddress(): Writes given bytes to given address.
  • procName is a name of a process.
  • dst is an address in the target process to write to.
  • bytes is data to be written by the function.
  • size is how many bytes to write.
• AutoWriteToOffset(): Writes given bytes to a given offset from a base address.
  • procName is a name of a process.
  • modName is a name of a module.
  • offset offset from an address to be written to.
  • bytes is data to be written by the function.
  • size is how many bytes to write.
• AutoWriteToPattern: Writes given bytes to a given address found via a pattern scan.
  • procName is a name of a process.
  • modName is a name of a module.
  • pattern is a pattern to be searched for.
  • mask is a mask for the pattern.
  • bytes is data to be written by the function.
  • size is how many bytes to write.
