| Function | Description | Typical Implementation | |----------|-------------|------------------------| | | Locate the target executable or library on disk or within a packaged archive. | File‑system scanning, manifest parsing, or user‑provided path. | | Integrity Verification | Ensure the binary has not been tampered with before loading (optional). | SHA‑256 hash checks, digital signatures, or checksums. | | Dependency Resolution | Load required shared libraries (DLLs, .so files) and manage version conflicts. | Custom loader path, LoadLibrary / dlopen wrappers, version‑mapping tables. | | Relocation & Fix‑ups | Adjust absolute addresses in the binary to match the actual memory layout. | PE/ELF relocation tables, runtime patching, or using OS‑provided relocation services. | | Code Injection / Hook Registration | Insert user‑supplied code at selected entry points (e.g., function prologues). | Inline patching, trampolines, Import Address Table (IAT) hooking, or API hooking via Detours/Frida. | | Configuration Management | Read user‑defined settings that control which patches or plugins are applied. | INI/JSON/TOML files, command‑line arguments, or a small embedded database. | | Sandboxing / Isolation | Optionally confine the loaded binary to reduce security impact. | Job objects (Windows), namespaces (Linux), seccomp filters, or sandbox runtimes. | | Logging & Telemetry | Capture events such as load failures, applied patches, and performance metrics. | Structured logging (e.g., JSON), event tracing, or external monitoring hooks. | | Self‑Update Mechanism | Allow the loader itself to be upgraded without reinstalling the host application. | Versioned assets, delta‑patch distribution, or auto‑update services. |
