patcherex

Patcherex is a binary patching tool primarily used for creating modified binaries by applying various types of patches, such as adding code or modifying execution paths within the original program. This tool supports different backend methods for patch injection, notably the DetourBackend and ReassemblerBackend, which allow for reliable manipulation of binary files. Patcherex also offers advanced techniques for binary analysis and modification, making it suitable for tasks such as backdoor insertion and return pointer encryption.
