Why Ships Are Easy Targets

Unlike corporate offices, vessels at sea don’t have dedicated IT teams watching for threats 24/7. Combine that with crew rotations, old equipment, and satellite internet — and you’ve got a recipe for vulnerabilities. Hackers know this.

Here’s what’s at risk:

• ECDIS manipulation: Wrong charts or altered routes
• AIS spoofing: Faked positions that mislead port control
• Bridge system lockouts: Ransomware targeting navigation consoles
• VSAT intrusions: Leaks of sensitive communications or crew data

Real-World Example: GPS Spoofing Incident in the Gulf

A commercial vessel reported drifting miles off course. The cause? Spoofed GPS signals injected via compromised software. Navigation logs showed no anomalies — until a manual check revealed the truth. Without cybersecurity protocols, it would’ve gone undetected.

The Business Impact

• Delays and detentions during port inspections
• Class non-compliance leading to insurance issues
• Increased cyber premiums and audit penalties
• Reputation damage if customer cargo or data is compromised

What IMO and Class Now Require

• Cyber risk management is now mandatory under the ISM Code
• Class societies like DNV, ABS, BV, and IRS include cybersecurity audits in their scope
• Port states are stepping up inspections of digital safety protocols

How Global Tech Helps Keep Your Vessel Secure

• Cyber audits tailored to vessel size and systems
• Firewall configuration and encrypted access to GMDSS, VSAT, and bridge controls
• Training for crew on cyber hygiene and threat detection
• Ongoing monitoring and alerts for flagged behavior
