Network Forensics

Reading the traffic for what it meant to hide.

Overview

Analysis of network traffic and infrastructure to identify anomalies, unauthorized access patterns, and data movement across systems — connecting what moved on the wire with what happened on the host.

Capabilities

What engagements deliver.

Each engagement is scoped to the incident. The capabilities below define the outer envelope of what we bring to the work.

C.01

Packet capture & traffic analysis

Deep inspection of captured traffic, flow records, and metadata to reconstruct sessions and protocols.

C.02

Lateral movement detection

Identify persistence mechanisms, credential reuse, and east-west patterns typical of advanced intrusions.

C.03

Data exfiltration patterns

Recognize staged, chunked, and covert transfer behaviors against a baseline of expected activity.

C.04

Network–endpoint correlation

Fuse network telemetry with host artifacts to produce a single, time-aligned picture of the event.

Lateral Movement Map

Reading intent in the spaces between hosts.

A representative lateral-movement path, reconstructed from flow, authentication, and endpoint telemetry.
