项目说明

PERE - PE Risk Engine

PERE is a lightweight Windows-focused static analysis engine for Portable Executable (PE) files. It inspects imported APIs, examines digital signature metadata, analyzes section structure, and computes a heuristic risk score to help triage suspicious binaries.

Features

Static PE analysis for .exe and .dll files

Import-based beha scoring

Beha scoring for correlated API patterns (persistence + injection, process hollowing, dropper behavior)

Section structure analysis and o detection

Packer/obfuscation heuristics using entropy and known markers

Entropy analysis for packed or obfuscated binaries

Detailed signature and signer metadata output

Signature trust e (unsigned, selfsigned, valid)

Detection of injection chains and stealth process injection patterns

Timestamp collection and anomaly scoring (--timestamps)

JSON report export

Colorized terminal output via colorama

Important Disclaimer

This tool is not a replacement for endpoint detection and response (EDR) systems. It is a lightweight, rapid triage utility for inspecting PE files (for example binaries that may have been dropped, modified, or used in an attack). Use it as a first-pass aid during in - follow up with full EDR, dynamic analysis, and forensic procedures for definiti.

Requirements

Python 3.11+ recommended

Windows en for meaningful PE analysis

Installation

1. Clone or download the repository.
2. Create a en (recommended):

3. Install dependencies:

Usage

Run the main analyzer with the target directory path:

Optional arguments:

--extensions: comma-separated extensions to scan (default: exe,dll)

--timestamps: include file and PE timestamp details, and score anomalous dates

--json: sa to a JSON report

--output: JSON output filename (default: report.json)

Example:

Demo

demo.webm

How It Works

main.py scans the provided directory and invokes analyzer.analyze_file() for each matching file.

analyzer.py loads the PE file using pefile, extracts imported functions, inspects Authenticode signature metadata, analyzes section structure, and optionally gathers timestamp metadata.

rules.py scores detected APIs, signature data, section anomalies, and timestamp anomalies when --timestamps is enabled, generating findings and a combined risk score.

engine.py currently forwards the e result from rules.py and can be extended for future scoring enhancements.

Risk Scoring

PERE uses grouped API scoring and heuristic detections such as:

Memory APIs (e.g. , WriteProcessMemory)

Injection APIs (e.g. CreateRemoteThread, OpenProcess)

Execution APIs (e.g. CreateProcessA, ShellExecuteW)

Dynamic loading APIs (LoadLibrary, GetProcAddress)

Persistence APIs (RegSet, RegCreateKeyEx)

Special pattern detections include:

Injection Chain

Stealth Injection

Dynamic API Resolution

O Detected

Packer / Obfuscator Signature

Trusted signed binaries from selected publishers can bypass scoring.
