The speed with which the maritime industry is adopting artificial intelligence (AI) technology to optimise operations, recruitment and maintenance is leaving the sector open to a swift, autonomous cyberattack that will be almost impossible to detect before it’s too late.
New data revealed in a Cydome Maritime Cyber Trends Report 2026: What Shipping Executives Need to Know, shows that up to 60% of all newly disclosed software vulnerabilities on ship, onshore and offshore are being weaponised within 48 hours as hackers also begin to use AI to accelerate attacks.
Tetsuji Madarame, maritime and logistics expert and former head of digital transformation and innovation at NYK Line, says in 2018, the average time from new software vulnerabilities being published to an actual attack was 63 days.
By 2024, it had fallen to five days.
“Today, AI-driven tools have reduced the hacking window to less than 48 hours, with many systems being targeted within just 15 minutes of a system flaw being detected.”
Findings from the report, published this week, indicate that 87% of organisations now view AI-related vulnerabilities as the fastest-growing risk, highlighting a dangerous collapse in the traditional security response window. While the technology streamlines operations, it also enables “flawless deception”.
Theofano Somaripa, group CIO of dry bulk operator Newport SA, says that cyberattacks in 2026 will be defined by a “shift in focus from digitalisation to the radical restructuring of business models through AI”.
The research notes that 83% of phishing emails already use AI to target multinational crews in their native language, and in a way that instantly establishes trust. This has led to a 1 600% surge in voice phishing (vishing), where AI clones the speech pattern of C-suite executives to authorise fraudulent transactions.
“Shipping companies are deploying AI faster than they are defining cyber accountability," warns Katerina Raptaki, IT manager at Greek shipping company Navios. "In 2026, the question after an incident won't be was the AI wrong, but why was it trusted?”
“In 2026, the most significant cybersecurity risk will come from inside the perimeter,” says Øystein Brekke-Sanderud, head of Maritime OT/ICS Security at NORMA Cyber. “As organisations become more digitally integrated, insider risk, whether malicious, compromised or accidental, will be one of the hardest challenges to detect and manage. Resilience will increasingly depend on how well we detect subtle signals early, not just how well we defend the edge."
Panagiotis Anastasiou, cybersecurity strategy leader with Bureau Veritas Marine & Offshore, further points out: “Attacks are inevitable and, as an incidents analysis indicates, are becoming more sophisticated; the differentiator will be how quickly and safely a shipping company can detect, respond and continue operations.”
The Cydome report draws on operational data, incident records and executive commentary from across the global maritime sector, with data and insight from 13 industry leaders, including shipowners and classification societies.
