Technical Architecture & Overview

peepdf parses PDF files and exposes their object structure, streams, and embedded JavaScript for inspection. It can decode filters, analyze shellcode with libemu, and check hashes against VirusTotal. The interactive console lets analysts walk the document tree and extract suspicious objects. Development activity is low, so treat it as a stable tool rather than a fast-moving one.

Targeted Technical Use Cases

Dissecting a suspicious PDF attachment to confirm an exploit or a JavaScript downloader.

Evaluation & Trade-offs

Core Strengths

  • +Interactive console purpose-built for PDF structure.
  • +Shellcode analysis built in.
  • +Simple to script for batch checks.

Trade-Offs & Limitations

  • -Sparse recent development activity.
  • -Newer PDF obfuscation can require manual decoding.

Defensive Security Application

Confirming malicious PDFs in phishing investigations and extracting indicators from embedded payloads.
