Greece Scans Systems After Iran Cyber Threat Warning

Greek companies, including shipowners, are conducting thorough system scans for cyberattacks following guidance from the National Cybersecurity Authority. This directive was issued last week as a pre-emptive measure due to incidents with potential links to recent geopolitical events. The advisory, marked as high-priority, was distributed to various sectors, including shipping, banking, and critical infrastructure. It urged firms to review their systems, block suspicious IP addresses, and report any confirmed incidents. Two sources confirmed that at least two shipping companies received this warning. Electronic interference with commercial navigation systems has notably increased around the Strait of Hormuz and the wider Gulf region. While initial reports suggest Greece has not yet identified a major attack, some network activity has been observed. Investigations into a confirmed incident abroad indicated a sophisticated actor employing advanced methods to mask their operations and evade detection.
