The Environment
A mid-sized intermodal port and freight terminal processes container shipping, bulk cargo, and road-rail transfers around the clock. The operational environment is complex and deeply networked: a terminal operating system (TOS) coordinates berth scheduling, crane operations, and gate management; CCTV and access control systems monitor the physical perimeter; GPS and AIS feeds track vessel movements; and a customs and trade compliance platform exchanges data continuously with government agencies and freight forwarders. The terminal grants network access to a rotating cast of third parties — shipping lines, freight brokers, customs agents, and logistics partners — through a shared access portal and a guest network used by vessel crews.
The port’s IT team is small and focused primarily on keeping operational systems available. The combination of 24/7 operations, high third-party access, and the integration of IT and OT systems across crane control, gate automation, and vessel scheduling creates an exceptionally broad attack surface. A disruption to port operations has immediate cascading effects across the regional supply chain.
Frostbow Deployment
Frostbow was deployed in the Complete Security Platform configuration with the TOS, customs platform, and crane control network designated as priority monitoring surfaces. The guest network and third-party access portal were treated as high-risk ingress points and monitored with heightened sensitivity. Crane control and gate automation systems were monitored passively — no agents on operational hardware. The TOS and customs platform received direct API integration for deep visibility into user activity and data access patterns. Deployment was phased across two weeks to avoid disruption to active shifts, with final cutover during a planned maintenance window.
The Scenario: Third-Party Credential Abuse and Cargo Data Manipulation
A freight broker with legitimate access to the customs and trade compliance platform had their credentials compromised through a phishing campaign targeting logistics sector companies. The attacker used the broker’s credentials to access the platform and began querying detailed cargo manifests: container contents, origin and destination, scheduled arrival windows, and assigned berth locations. After two sessions of data harvesting, the attacker attempted to modify a number of manifest records — altering declared cargo contents on containers scheduled for arrival the following morning.
How Frostbow Responded
The broker’s account authenticated from an IP address not previously associated with the account. Frostbow flagged this as medium-confidence — freight brokers frequently work from varied locations — and monitored the session without acting.
The escalation came from the query pattern. Where a typical broker session involved accessing a handful of specific shipments relevant to their portfolio, this session queried 47 distinct cargo manifests across multiple shipping lines in under 25 minutes — well outside the broker’s established behavioral baseline. Frostbow identified this as matching its BulkCargoDataEnumeration concept, formed from prior observations of anomalous data harvesting in logistics environments.
When the session transitioned from read activity to write activity — attempting to modify manifest records — Frostbow immediately revoked the session, locked the broker account, and generated a high-priority alert. The attempted manifest modifications were blocked before being committed. A full record of the queried manifests and the attempted changes was captured in the incident report, providing customs authorities and port security with precise detail on what had been accessed and what had been attempted. The containers flagged in the attempted modification were held for additional physical inspection as a precautionary measure.
Key Deployment Characteristics
- Third-party access portal and guest network treated as elevated-risk ingress surfaces
- TOS and customs platform integrated via direct API for user-level behavioral visibility
- Passive monitoring of crane control and gate automation — no agent on operational hardware
- Phased deployment across 24/7 operational environment with no service disruption
- Attempted data manipulation blocked before record changes were committed
- Incident report detailed enough to support customs authority notification and physical inspection decisions
