Rising cyber threats in maritime communications
Following up on our recent newsletter about evolving email phishing threats in the shipping industry, it’s clear that the sector faces increasing risks as cybercriminals adapt to new technology. With improved connectivity and operational efficiency through satellite internet solutions like Starlink, the attack surface for cyber threats has expanded significantly. This means that shipping companies must strengthen their defenses to protect sensitive data and ensure operational continuity.
Key cybersecurity threats in maritime email
Phishing attacks are on the rise
Phishing remains one of the most prevalent cybersecurity threats in maritime email. Cybercriminals often impersonate legitimate contacts such as shipping agents, port authorities, or company executives to steal credentials, redirect payments, or install malware. With many crew members accessing email accounts from different devices and locations, the risk of falling for phishing scams has increased.
Why it’s a problem:
- Attackers use social engineering tactics to manipulate recipients into sharing sensitive data
- Phishing emails can lead to financial fraud, ransomware infections, or unauthorized access to operational systems
- Many phishing attempts can bypass traditional spam filters, making them harder to detect
AI-driven threats: the next generation of cyber attacks
Artificial Intelligence AI is not only being used to strengthen cyber defences but also becoming a powerful tool for attackers. Cybercriminals now use AI-powered tools to automate phishing attempts, create highly personalized scam emails, and bypass traditional security measures.
Why it’s a problem:
- AI-generated emails can convincingly mimic real messages, making phishing harder to detect
- Attackers can automate large-scale attacks, targeting multiple vessels simultaneously
- Traditional security solutions may struggle to keep up with the sophistication of AI-generated content
Increased bandwidth = more risk
Faster satellite internet like Starlink enables more reliable onboard connectivity. Vessels are more connected than ever. While this improves efficiency, it also means that cybercriminals have more opportunities to exploit security weaknesses.
Why it’s a problem:
- More internet usage leads to higher exposure to phishing, malware downloads, and unauthorized access
- Faster connections mean attacks can spread quickly if security measures are not in place
- Crew members may unknowingly access unsafe websites or download malicious content

Tips to protect your fleet’s email from cyber threats
1. Implement advanced email security solutions
A robust email security solution should include:
- Anti-phishing protection – scans emails for suspicious links and fraudulent senders
- Multiple malware scanners – detects and blocks harmful attachments before they reach the recipient. A single scanner is no longer sufficient.
- Spam filtering – identifies and quarantines unwanted or harmful messages
- Domain authentication checks – uses spf, dkim, and dmarc to verify legitimate senders and prevent spoofing attacks
2. Eliminate shared logins to email accounts
Shared email accounts also pose a significant security risk. When multiple crew members use a single account, it becomes difficult to track who is responsible for specific messages, making it easier for attackers to exploit credentials.
Recommended solution: switch to individual logins with role-based access to improve accountability and security.

3. Enforce multi-factor authentication (MFA)
MFA significantly reduces the risk of unauthorized access by requiring an additional layer of verification beyond just a password. Enforcing MFA ensures that even if credentials are compromised, attackers cannot easily gain access.
4. Conduct regular cybersecurity training
Crew members should be trained to recognize phishing emails, avoid clicking on suspicious links, and report potential threats. Human error remains one of the leading causes of successful attacks, so increasing awareness is critical.
5. Use a secure maritime email solution
A dedicated email solution designed for maritime operations, provides the necessary security and control to mitigate email-related cyber threats. With features like advanced threat detection, onboard and cloud backup, and central fleet-wide email management, shipping companies can ensure their communication remains secure and uninterrupted.

The cost of inaction: cybersecurity is an investment, not an expense
Many shipping companies hesitate to invest in cybersecurity solutions due to perceived high costs. However, the financial impact of a successful cyberattack, including ransom payments, operational downtime, and reputational damage, far outweighs the cost of proactive measures. Strengthening your email security is a necessary investment in the future resilience of your fleet.
Stay ahead of cyber threats
As maritime cyber threats continue to evolve, proactive security measures are essential. By implementing advanced email security solutions, eliminating shared email accounts, enforcing MFA, and using a dedicated maritime email system, shipping companies can significantly reduce their cyber risk.
Cybersecurity is no longer optional; it’s a critical component of safe and efficient maritime operations. Don’t wait for a breach to take action, secure your fleet’s email communication today.
