Intelligence Network
Welcome to SENTINEL Command Center. Objective Defender is in play. The following missions require immediate attention. Select a mission to begin.
WebXR / Augmented Reality
Deploy holographic data archive in physical space. Interactive 3D library experience with tap-to-read functionality. Requires AR-capable device and camera access.
Steganography / LSB Decode
Intercepted carrier signal contains concealed intelligence. Deploy LSB extraction protocol to reveal hidden data streams. Load stego_challenge.png to begin.
Audio Forensics / Spectrogram
Audio transmission detected with anomalous frequency patterns. Perform spectral analysis to extract visual data from frequency domain. Load sentinel_audio_challenge.wav.
Cipher / Pattern Recognition
Encrypted cipher stream detected. Decode geometric patterns using historical encryption methods. Type correct keyword to stabilize transmission and reveal target location.
AI / RAG Attack Simulation
Adversarial optimization challenge. Use gradient descent to poison RAG embedding space. Manipulate semantic similarity to extract classified data from target centroid.

SENTINEL (Surveillance and Encrypted Network Threat Intelligence Node Extraction Layer) is a comprehensive security analysis platform. Each mission represents a different attack vector or forensic challenge commonly encountered in cybersecurity operations.
Getting Started:
Specialized forensics utilities for field operations. These browser-based tools work offline and process all data locally - no server uploads required.
LSB Extraction / Image Forensics
Extract hidden data from images using Least Significant Bit analysis. Supports PNG and BMP formats. Detects concealed text, files, and binary data embedded in pixel values.
Spectral Analysis / Audio Forensics
Visualize audio frequency content over time using FFT-based spectrogram analysis. Reveals hidden images, text, and data encoded in the frequency domain of audio files.
Classified dossiers and operational intelligence. Review these documents to understand the threat landscape and mission parameters. Clearance Level 5 required.
