Steganography Detection and AI-Powered Log Analysis Workflow

Описание и применение

Автор исследует методы стеганографии и анализа логов. Использованы steghide для извлечения скрытых данных из изображений, exiftool для получения геолокации и Aperi'Solve для автоматизированного анализа. ИИ-ассистент помог проанализировать 10 000 строк логов Apache на наличие аномалий.

Задача

How to reliably detect and extract hidden data from images using steganography tools and how to use AI to speed up the analysis of large volumes of system logs for anomalies.

Результат

Successfully extracted a hidden text file from an image and identified its GPS location. Automated steganalysis confirmed the presence of hidden data. AI assistance enabled efficient triage of large log datasets to identify suspicious patterns and build incident timelines.

Рабочий процесс

• Extract hidden message from image using steghide with a passphrase.
• Pull GPS coordinates and metadata from image EXIF data using exiftool.
• Run automated steganalysis on the image using Aperi'Solve to check for various hiding techniques (bit-plane, steghide, outguess, etc.).
• Practice log analysis fundamentals by tracing a simulated breach through Windows event logs.
• Use AI assistant to triage 10,000 lines of Apache access logs for suspicious activity.
• Build a timeline from system logs to correlate events.
