Network Forensics Module

Overview#

The Network Forensics module provides packet capture analysis, protocol dissection, and traffic intelligence capabilities for law enforcement and cyber investigation professionals. Investigators can analyze network communications, reconstruct data sessions, detect malicious command-and-control traffic, and extract critical evidence from network captures with court-ready documentation.

The platform supports over 200 network protocols with automated detection and analysis, enabling investigators to build cases from digital communications evidence without requiring deep protocol expertise.

Key Features#

• PCAP Analysis -- Automated protocol detection across 200+ protocols with deep packet inspection, payload extraction, encryption fingerprinting, and anomaly detection
• Session Reconstruction -- Reassemble complete TCP conversations from fragmented packets, including HTTP browsing history, email messages, file transfers, VoIP calls, and remote desktop sessions
• Malware C2 Detection -- Behavioral analysis engine identifying command-and-control communications through beacon analysis, domain generation algorithm detection, DNS tunneling recognition, and encrypted traffic pattern matching
• Traffic Intelligence -- Interactive network timelines, GeoIP mapping, statistical analysis, top talker identification, and communication pattern visualization
• Evidence Extraction -- Automated file carving for 100+ file types, credential identification, metadata extraction, and cryptographic hashing for evidence integrity
• Court-Ready Reporting -- Generate evidence reports with executive summaries, methodology documentation, chain of custody records, technical findings, and glossaries of terms
• Team Collaboration -- Real-time case sharing with role-based access, annotation tools, task assignment, and prosecutor-ready evidence portals
• Threat Intelligence Integration -- Real-time threat feed matching, known C2 server identification, malware family classification, and APT group attribution

Use Cases#

• Cybercrime Investigation -- Reconstruct ransomware attacks from initial access through data exfiltration, identifying attacker infrastructure, communication protocols, and stolen data for prosecution
• Dark Web Investigations -- Analyze Tor traffic patterns, correlate marketplace activity timing, track cryptocurrency communications, and recover vendor identity evidence
• Insider Threat Detection -- Compare baseline traffic patterns against incident-day activity, identify unauthorized data uploads, reconstruct transferred files, and confirm employee attribution
• Child Exploitation Cases -- Identify peer-to-peer file sharing, match file hashes against known databases, recover content, and build court-admissible evidence packages
• APT Investigation -- Detect advanced persistent threats through behavioral analysis, TLS fingerprinting, infrastructure mapping, and correlation with threat intelligence feeds

Integration#

The module integrates with device forensics, blockchain analytics, geospatial intelligence, and social network analysis tools within the Argus platform. Supports PCAP, PCAPNG, and additional capture formats with export to standard formats for compatibility with external tools. Compliant with CJIS, GDPR, and digital evidence preservation standards.
