wraith-rs

Safe, idiomatic Rust abstractions for Windows process internals and security research.

What is wraith-rs?

wraith-rs provides high-level APIs for interacting with Windows internals that are typically only accessible through undocumented structures and techniques. It's designed for security researchers, anti-cheat developers, and anyone who needs to understand or manipulate Windows processes at a low level.

use wraith::{Peb, Teb};
use wraith::navigation::ModuleQuery;

// Access process internals without raw pointers
let peb = Peb::current()?;
let teb = Teb::current()?;

println!("Image base: {:#x}", peb.image_base());
println!("Thread ID: {}", teb.thread_id());

// Find and inspect loaded modules
let query = ModuleQuery::new(&peb);
let ntdll = query.find_by_name("ntdll.dll")?;
let nt_open_process = ntdll.get_export("NtOpenProcess")?;

Features

Core Navigation

• PEB/TEB Access: Safe wrappers around Process/Thread Environment Blocks with version-aware field offsets (Windows 7 through Windows 11 24H2)
• Module Enumeration: Iterate loaded modules via all three PEB lists (InLoadOrder, InMemoryOrder, InInitializationOrder)
• Export Resolution: Find exported functions by name, ordinal, or hash
• Memory Region Queries: Enumerate process memory regions with protection info
• Thread Enumeration: List threads in the current process
• Pattern Scanning: Scan memory for byte patterns with wildcard support (IDA-style signatures)

Advanced Manipulation

Comparison with Other Libraries

*Core functionality has no required dependencies. Optional log integration available.

Why not just use ntapi/windows-sys?

Those are FFI bindings - they give you the raw function signatures. wraith-rs builds on top of those concepts to provide:

1. Safety: No raw pointer juggling. Bounds checking on PE parsing. Validation on all inputs.
2. Ergonomics: Iterator patterns, builder APIs, proper error types.
3. Portability: Version-aware offsets mean code works across Windows versions without #[cfg] everywhere.
4. Completeness: Full workflows (parse PE → allocate → map → relocate → resolve imports → call entry point) not just primitives.

Usage Examples

Module Enumeration

use wraith::Peb;
use wraith::navigation::{ModuleIterator, ModuleListType};

let peb = Peb::current()?;

for module in ModuleIterator::new(&peb, ModuleListType::InLoadOrder)? {
    println!("{} @ {:#x} ({} bytes)",
        module.name(),
        module.base(),
        module.size()
    );
}

Pattern Scanning

use wraith::util::{Scanner, Pattern, find_pattern_in_module};

// Scan a module for an IDA-style pattern
let matches = find_pattern_in_module("ntdll.dll", "48 8B 05 ?? ?? ?? ?? 48 89")?;
for m in &matches {
    println!("Found at {:#x} (offset {:#x})", m.address, m.offset);
}

// Use the Scanner builder for more control
let scanner = Scanner::new("E8 ?? ?? ?? ?? 90")?
    .alignment(1)       // check every byte (default)
    .max_results(100);  // limit results

// Scan a specific module
let peb = wraith::Peb::current()?;
let query = wraith::navigation::ModuleQuery::new(&peb);
let ntdll = query.find_by_name("ntdll.dll")?;
let calls = scanner.scan_module(&ntdll)?;
println!("Found {} CALL instructions", calls.len());

// Scan all executable memory regions
let results = scanner.scan_executable_regions()?;

// Code-style pattern (bytes + mask)
let pattern = Pattern::from_code(
    &[0x48, 0x8B, 0x05, 0x00, 0x00, 0x00, 0x00],
    "xxx????"  // x = exact, ? = wildcard
)?;
let scanner = Scanner::from_pattern(pattern);

Direct Syscalls

use wraith::manipulation::syscall::{SyscallTable, DirectSyscall};

// Enumerate syscalls from ntdll
let table = SyscallTable::enumerate()?;

// Get NtClose
let entry = table.get("NtClose").unwrap();
println!("NtClose SSN: {}", entry.ssn);

// Invoke directly (bypasses any usermode hooks)
let syscall = DirectSyscall::from_entry(entry);
let status = unsafe { syscall.call1(invalid_handle) };

Hook Detection

use wraith::manipulation::hooks::{HookDetector, scan_for_hooks};

// Scan common system DLLs for hooks
let hooks = scan_for_hooks()?;

for hook in hooks {
    println!("[HOOKED] {}!{} - {}",
        hook.module_name,
        hook.function_name,
        hook.hook_type
    );
    if let Some(dest) = hook.hook_destination {
        println!("  Redirects to: {:#x}", dest);
    }
}

Manual PE Mapping

use wraith::manipulation::manual_map::ManualMapper;

// Map a DLL without LoadLibrary - invisible to GetModuleHandle
let mapper = ManualMapper::from_file("my.dll")?
    .allocate()?
    .map_sections()?
    .relocate()?
    .resolve_imports()?
    .process_tls()?
    .finalize()?;

// Call DllMain
mapper.call_entry_point()?;

// Get exports from the mapped image
let func = mapper.get_export("MyFunction")?;

Module Unlinking

use wraith::navigation::ModuleQuery;
use wraith::manipulation::unlink::unlink_module;

let peb = Peb::current()?;
let query = ModuleQuery::new(&peb);
let handle = query.get_module_handle("target.dll")?;

// Remove from all PEB lists
let guard = unlink_module(handle)?;

// Module is now hidden from GetModuleHandle, EnumProcessModules, etc.
// Guard automatically relinks on drop, or call guard.leak() to keep hidden

Anti-Debug

use wraith::manipulation::antidebug;

// Check current debug status
let status = antidebug::get_debug_status()?;
println!("BeingDebugged: {}", status.being_debugged);
println!("NtGlobalFlag: {:#x}", status.nt_global_flag);

// Clear debug indicators
antidebug::clear_being_debugged()?;
antidebug::clear_nt_global_flag()?;
antidebug::clear_heap_flags()?;

// Hide current thread from debugger
antidebug::hide_current_thread()?;

Windows Version Support

wraith-rs uses version-specific offset tables for accurate structure access:

Unknown versions fall back to Windows 10 offsets with a warning.

Architecture Support

• x86_64: Full support
• x86 (32-bit): Supported for most features
• ARM64: Not currently supported

Safety

wraith-rs uses #![deny(unsafe_op_in_unsafe_fn)] and documents all safety invariants. The library is designed to be safe against:

• Malformed PE files: Bounds checking on all RVAs and array accesses
• Corrupted PEB lists: Iteration limits and null checks prevent infinite loops
• Invalid syscall addresses: Validation that target contains actual syscall instruction
• Buffer overflows: String reads are bounded, no unbounded loops

However, many operations are inherently unsafe at the OS level (modifying PEB, invoking syscalls, mapping executable code). The library makes these as safe as possible but cannot prevent all misuse.

Intended Use

This library is designed for:

• Security research and authorized penetration testing
• Anti-cheat and anti-tamper development
• EDR/AV development and testing
• Malware analysis and reverse engineering
• Educational purposes

Users are responsible for ensuring they have proper authorization before using these techniques on any system or software.

1. Code compiles with cargo build --all-features
2. Tests pass with cargo test --all-features
3. No new clippy warnings
4. Unsafe code has // SAFETY: comments explaining invariants
