ppm-engine 0.2.2

Binary analysis engine -- reconstruct architecture from compiled binaries in seconds

Paradex Process Monitor

Binary reconstruction & kernel inspection platform.

PPM takes any compiled binary (.sys, .exe, .dll, .ocx, .ko, .so, .dylib, .lnk) and automatically reconstructs its architecture: what callbacks it registers, what APIs it calls, what attack chains it implements -- in seconds, not hours.

Supported Formats

Format	Adapter	Capabilities
PE (exe/dll/sys/ocx)	PEAdapter	IAT, imports, strings, callgraph, patterns, chains
ELF (Linux binaries/ko)	ELFAdapter	PLT calls, imports, strings, kernel module detection
Mach-O (macOS/iOS)	MachOAdapter	dyld bindings, stub resolution (ARM64+x64), indirect symbol table
LNK (Windows shortcuts)	LNKAdapter	Target/args extraction, LOLBin/Base64/hidden window risk assessment
Media/docs	detect only	JPEG, PNG, WAV, PDF, ZIP, MP4, TEXT, and 12 more

Non-binary formats (images, audio, text) are correctly identified and rejected -- no crashes on unexpected input.

Quick Start

Install Engine (Python)

cd engine
pip install -e .
# Optional: pip install lief  (for ELF/Mach-O support)

Usage

# Analyze a binary (JSON output)
echo '{"command":"analyze","path":"driver.sys"}' | python -m ppm_engine

# Detect format only
echo '{"command":"detect","path":"unknown.bin"}' | python -m ppm_engine

# Query dependency graph
echo '{"command":"depgraph","path":"driver.sys","query":"who_registers ObCallback"}' | python -m ppm_engine

# Ping (check engine status)
echo '{"command":"ping"}' | python -m ppm_engine

C++ CLI (coming soon)

cmake -B build -G Ninja
cmake --build build

./ppm --json analyze driver.sys    # Agent mode
./ppm --quiet /analyze driver.sys  # CLI mode
./ppm                              # GUI mode (Dear ImGui)

Analysis Pipeline

detect --> unpack --> adapt --> callgraph --> depgraph --> patterns --> chains --> reconstruct

Pattern Detection

Pattern	What it detects	Confidence
ob_callback	ObRegisterCallbacks handler registration	0.75-0.9
cm_callback	CmRegisterCallbackEx registry callback	0.7-0.85
apc_inject	APC injection chain (notify+process+memory+APC)	0.4-0.9
dkom	Direct Kernel Object Manipulation (PsLoadedModuleList, ActiveProcessLinks)	0.3-0.8
handle_strip	Handle access bit stripping (AND mask pattern)	0.7-0.85

depgraph Queries

graph.who_registers("ObCallback")    # Type aliases: ObCallback, CmCallback, notify, minifilter
graph.who_registers("callback")      # Substring match across all callback types
graph.find_sinks("ZwTerminateProcess")  # All paths from entry to dangerous API
graph.trace_from("func_0x1458")      # BFS tree from any node
graph.impact_of("func_0x78B8")       # What breaks if this function is patched
graph.find_path("func_A", "func_B")  # Shortest path between two nodes

Architecture

Two-process design: C++ GUI/CLI + Python analysis engine, connected via JSON over stdin/stdout.

ppm (C++)                          ppm-engine (Python)
  Plugin system (9 plugins)          detect, unpack, topology
  Dear ImGui GUI                     depgraph, patterns, chains
  Kernel ops (BYOVD)                 reconstruct, bridges
  CLI + --json agent mode            LNK risk assessment

Input Hardening

All user-supplied paths are sanitized before processing:

• Protocol injection blocked (http/ldap/jndi/file)
• UNC paths blocked
• Windows reserved device names blocked (CON/NUL/PRN -- prevents open() hang)
• Unicode direction overrides stripped
• Null bytes stripped
• Non-binary formats safely rejected

Tested with 37 chaos/injection inputs: zero crashes.

Testing

Test Driver

tests/samples/rk64.sys -- synthetic 5KB driver that triggers all detection patterns:

• 4 patterns: ob_callback(0.9), cm_callback(0.85), apc_inject(0.8), dkom(0.5)
• 36 chains, 5 callbacks, 4 self-protection mechanisms
• DKOM strings, anti-analysis process targets, handle stripping

Stress Test Results

470 system drivers from C:\Windows\System32\drivers:

• 0 errors, 0 crashes
• Largest: RTKVHD64.sys (6.3MB), most functions: Netwtw10.sys (9,141)
• False positive rates: apc_inject 0.8%, dkom 0.6%

External Bridges (Optional)

Bridge	System	Purpose
QCU	treesea/qcu	Quantum collapse for ambiguity resolution
URP	URX Runtime	Distributed analysis scheduling
exMs	exMs	ELF syscall emulation
HCE	treesea/hce	Unified orchestration
