Silent Exploit PDF Builder

HexSec PDF Exploit Builder is a powerful and modular tool designed for red teamers, penetration testers, and advanced cybersecurity researchers.

This utility generates custom PDF documents with embedded Base64-encoded payloads (e.g., shellcode or PE binaries) fetched from remote servers. It simulates stealth injection into system processes such as `svchost.exe`, `explorer.exe`, or `winlogon.exe`, while applying advanced evasion techniques to bypass antivirus and EDR detection.


🔐 Features

- Remote payload retrieval over HTTPS
- Base64 payload parsing and disassembly
- Operator-defined process injection (svchost.exe, winlogon.exe, etc.)
- AES-like encryption stagers
- Entropy blob injection to increase stealth
- PDF generation with custom visible text
- Virtual machine and debugging detection
- In-memory shellcode execution (never written to disk)
- Fully undetectable (FUD) by most AVs & EDRs


> ⚠️ The PDF must be saved locally and opened with a native PDF reader (e.g. Adobe Reader, SumatraPDF, etc.) for the injection to occur.
> Opening via online previewers (Google Drive, browser, etc.) disables execution.
