French authorities have arrested two crew members of an Italian passenger ferry, including a Latvian national, for allegedly installing malware on the vessel. This malware could have allowed them to gain remote control over the ship, raising serious concerns about maritime security. The incident underscores the vulnerabilities that can exist in critical infrastructure like passenger ferries, where cyberattacks could potentially endanger lives and disrupt operations. Authorities are investigating the extent of the malware's capabilities and the intentions behind its installation. This case serves as a reminder for the maritime industry to enhance cybersecurity measures to protect against similar threats.
