Do you trust that shipping companies are doing enough to secure their vessels from cyberattacks?
A cybersecurity study by CYTUR has identified that 94% of assessed shipboard systems require treatment for vulnerabilities, with 60% falling into a mandatory remediation category. This research follows a suspected cyberattack on the Vivit Africa, where crew members reported unauthorized access to critical control systems.
Why it matters
The findings underscore critical security gaps in maritime infrastructure where end-of-support software and legacy vulnerabilities persist in modern equipment. This reliance on aging, insecure control systems threatens the operational integrity of global shipping fleets.
CYTUR found that one integrated automation system contained 200 known CVEs, while others held 20 or 13, and one firewall operating system accounted for 37 vulnerabilities. Remediation measures, including software updates and encryption, successfully reduced one system's risk score from 20 to 12.
The players
CYTUR
A research organization focused on evaluating the security and resilience of industrial and maritime control systems.
Vivit Africa
A cargo vessel that reportedly experienced a temporary loss of control over safety and pressure systems.
The details
Researchers reviewed equipment from over 10 manufacturers, finding that many newly installed units run outdated operating systems with publicly disclosed vulnerabilities that are more than three years old. These systems often feature bundled PLCs (Programmable Logic Controllers—industrial computers that automate manufacturing processes) and HMIs (Human-Machine Interfaces—dashboards that allow operators to control machines). The Vivit Africa reportedly suffered from manipulated steam pressure and tank valves, which Italy's coastguard confirmed was a cargo-monitoring malfunction.
Timeline
Three years prior: Vulnerabilities were originally disclosed for the assessed equipment.
September 20, 2026: Reports emerged of the cyberattack on the Vivit Africa.
September 21, 2026: The CYTUR research was published.
The Tech Race
The maritime sector is currently lagging behind other industrial domains in securing its legacy hardware stack. This research exposes a systemic failure to address vulnerabilities in integrated automation systems that are increasingly exposed to the public internet.
Shipping operators and fleet managers face immediate pressure to perform audits of existing control hardware to identify systems running end-of-support software. Future operations may rely on mandatory encrypted communications and frequent firmware patching cycles to mitigate these newly quantified risk levels.
The takeaway
The prevalence of unpatched vulnerabilities in critical maritime infrastructure suggests that hardware security will remain a primary focus for regulatory bodies. Stakeholders should monitor for new maritime cybersecurity standards or mandatory firmware update requirements following this disclosure.
