skidscan

Quick & dirty Rust sigscanning crate.

Features

  • Cross-platform
  • Scan for patterns from a pointer
  • Scan for patterns in a byte slice
  • Scan for patterns in a loaded shared library (.so/.dll)
  • "Obfuscated signatures" using obfstr

Usage

let sig = signature!("40 53 48 83 EC 20 48 8B 01 48 8B D9 48 89 91 ? ? ? ? FF 90 ? ? ? ? 33 D2");
let sig = obfsignature!("40 53 48 83 EC 20 48 8B 01 48 8B D9 48 89 91 ? ? ? ? FF 90 ? ? ? ? 33 D2"); // "Obfuscated" signature

let result: Result<*mut u8, ModuleSigScanError> = sig.scan_module("path or module name");
let result: Option<usize> = sig.scan_ptr(0xDEADBEEF as *mut u8);
let result: Option<usize> = sig.scan(&[0x40, 0x53, 0x48, 0x83, 0xEC, 0x20, 0x48, 0x8B, 0x01, 0x48, 0x8B, 0xD9, 0x48, 0x89, 0x91, 0x00, 0x00, 0x00, 0x00, 0xFF, 0x90, 0x00, 0x00, 0x00, 0x00, 0x33, 0xD2]);

Signatures

Signatures are constructed as a series of Option<u8>.

None represents a ?: any byte, so long as it is present.

Some(u8) represents this byte exactly.

For example, signature!("48 89 91 ? ? ?") becomes [Some(0x48), Some(0x89), Some(0x91), None, None, None]

Obfuscated Signatures

You can construct an "obfuscated" signature using obfstr with the obfuscate crate feature.

Obfuscated signatures are constructed, for each byte: Some(obfstr!("0xFF").parse::<u8>())

For example, signature!("48 89 91 ? ? ?") becomes [Some(obfstr!("0x48").parse::<u8>()), Some(obfstr!("0x89").parse::<u8>()), Some(obfstr!("0x91").parse::<u8>()), None, None, None]
