Greek authorities have issued a high-priority cyber alert to shipping companies, banks, and critical infrastructure operators following a surge in activity linked to the Iran conflict. According to their report, organizations are actively scanning their networks for indicators of compromise, including malicious IPs, tools, and malware such as the VShell remote access trojan. The warning follows confirmed cyber incidents in other regions — including attacks on U.S. and Albanian targets — highlighting a growing pattern of state-aligned cyber activity targeting global infrastructure and supply chains.

The advisory points to sophisticated threat actors using multi-layered infrastructure for reconnaissance, unauthorized access attempts, and command-and-control (C2) operations, making detection significantly more challenging. In parallel, there has been a rise in electronic interference affecting maritime navigation systems in critical regions like the Strait of Hormuz, signaling that cyber operations are increasingly converging with physical and geopolitical disruptions. The presence of any nefarious activity underscores how organizations may already be in the early stages of intrusion without full visibility.

To defend against these evolving threats, organizations must move beyond reactive scanning and adopt continuous, real-time visibility across network, application, and security layers. This requires monitoring network traffic (packets and flows), authentication logs, system events, and C2 communications to detect reconnaissance, lateral movement, and data exfiltration attempts early. By correlating L2–L7 network analytics with logs and threat intelligence in a single platform like NIKSUN, security and NetOps teams can identify hidden attacker infrastructure, block malicious connections in real time, and maintain a full forensic record — critical for both rapid response and resilience in an era of escalating cyber warfare.
