🌐 How We Investigate Large-Scale Data Breaches, Network Intrusions

In today’s connected world, cyber threats rarely remain confined to a single machine. They propagate silently across networks, escalate privileges, and compromise systems at scale. Our network forensics service is engineered to meet the growing complexity of these attacks—enabling us to investigate, reconstruct, and respond to sophisticated incidents that span entire infrastructures.

From enterprise LANs to hybrid cloud ecosystems, we apply advanced forensic methodologies to detect and trace unauthorized activity, no matter how deeply embedded. Our work supports not only post-incident investigations but also proactive threat hunting and security posture assessments.

We specialize in:

  • Capturing and decoding raw network traffic (packets, sessions, logs)
  • Rebuilding attacker timelines and identifying their movement through systems
  • Linking actions to specific users, IPs, or malware strains
  • Uncovering stealthy exfiltration methods such as DNS tunneling or encrypted payloads
  • Tracing insider misuse or unauthorized access to sensitive systems

Whether you’re facing a ransomware outbreak, a suspected data leak, or unexplained system anomalies, we bring clarity to chaos. Our forensic teams collaborate closely with IT, InfoSec, and legal departments to contain the threat, preserve evidence, and document the incident with full legal defensibility.

When a breach threatens your infrastructure, our forensic insight gives you control—swiftly, securely, and comprehensively.

Network Forensics Process

🧠 What Is Network Forensics?

Network forensics is the systematic collection, monitoring, and analysis of network data to detect unauthorized access, data exfiltration, and anomalies. It plays a critical role in:

  • Breach investigations
  • Insider threat detection
  • Malware tracing
  • Compliance audits
  • Incident response and containment

Unlike device forensics, which focuses on data stored on physical hardware, network forensics deals with data in motion—packets, session logs, routing metadata, and firewall activity.

🧰 Our Process for Large-Scale Network Forensics

1. Scoping & Threat Identification

We begin by identifying the network boundaries, key infrastructure, and potential attack vectors. We work with IT and security teams to understand the scope and objectives of the investigation.

2. Data Capture & Collection

Using passive and active methods, we collect:

  • Network traffic (PCAP files) from firewalls, routers, and taps
  • NetFlow or IPFIX logs
  • IDS/IPS logs (e.g., Snort, Suricata)
  • Authentication and session logs (Active Directory, VPN, etc.)
  • Cloud access records and SIEM data

All collected data is timestamped, hashed, and securely stored to maintain integrity and evidential admissibility.

3. Timeline Reconstruction & Traffic Analysis

We reconstruct:

  • Sessions and communication chains
  • Lateral movement and privilege escalation paths
  • Exfiltration channels (e.g., DNS tunneling, HTTP POSTs, encrypted transfers)
  • Anomalous traffic patterns and unauthorized services

Our tools include Wireshark, Arkime (Moloch), Zeek (Bro), ELK stacks, and custom scripts built to analyze large-scale logs at speed.

4. Threat Attribution & Malware Tracing

We correlate traffic with threat intelligence databases to identify known IOCs (Indicators of Compromise), C2 servers, or malware payloads. Where needed, we isolate malicious binaries and reverse-engineer network behaviors.

5. Reporting & Recommendations

Our deliverables include:

  • A full technical report with incident chronology
  • Evidence of attacker actions and breached assets
  • Recommendations for containment, recovery, and patching
  • Optional executive summary and board-ready briefing

All findings are aligned with NIST 800-61, ISO/IEC 27035, and legal evidentiary requirements for prosecution or litigation support.

🧑‍💻 Scalable for Complex Environments

Whether it’s a multi-site corporate WAN, a government data center, or a hybrid cloud deployment, our tools and team scale to meet the challenge. We support:

  • Microsoft Azure / AWS / Google Cloud forensics
  • Office 365 and Exchange Server logs
  • VPN and remote work traffic analysis
  • OT (Operational Technology) network incidents
  • Insider threat scenarios with enterprise-wide reach

🔐 Confidential. Forensically Sound. Actionable.

We understand the sensitivity of enterprise breaches. Every case is handled with absolute confidentiality, a strict chain of custody, and clear communication from initial containment through final resolution.

When the breach is complex, our clarity is critical. Let us uncover what happened—before it happens again.
