HexSec PDF Exploit Builder is a powerful and modular tool designed for red teamers, penetration testers, and advanced cybersecurity researchers.br br 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.br br br 🔐 Featuresbr br - Remote payload retrieval over HTTPSbr - Base64 payload parsing and disassemblybr - Operator-defined process injection (svchost.exe, winlogon.exe, etc.)br - AES-like encryption stagersbr - Entropy blob injection to increase stealthbr - PDF generation with custom visible textbr - Virtual machine and debugging detectionbr - In-memory shellcode execution (never written to disk)br - Fully undetectable (FUD) by most AVs & EDRsbr br br ⚠️ The PDF must be saved locally and opened with a native PDF reader (e.g. Adobe Reader, SumatraPDF, etc.) for the injection to occur.br Opening via online previewers (Google Drive, browser, etc.) disables execution.
