Greece’s National Cybersecurity Authority denied that it had sent any warning letter to companies and public bodies about possible Iranian cyberattacks, despite recent reports suggesting otherwise.
In an official statement, the authority said it was cautious about issuing broad warning notices that could heighten anxiety without offering specific grounds or well-substantiated security guidance.
It noted that malicious activity linked to Iranian actors in the areas of espionage and cybercrime had been known and documented for a long time, and added that there was no indication this threat had changed in any meaningful way as a result of the recent military operations in the region. Vigilance, it said, remained a constant and self-evident requirement.
Against that backdrop, the authority said that media reports circulating since the afternoon of Wednesday March 18— citing Reuters as their source — which referred to “heightened alert over hackers linked to Iran following an urgent notice sent by the National Cybersecurity Authority to companies and institutions,” had been wrongly attributed to it. It stressed that no warning letter on the issue had been sent by the agency to any recipient.
