Iran says repelled ‘one of world’s most complex’ cyberattacks on national infrastructure

Iran has successfully repelled what it described as one of the world’s most complex cyberattacks, targeting critical national infrastructure linked to a domestic telecommunications operator, according to the country’s Minister of Information and Communications Technology.

Speaking during a meeting of the Steering Council for Communications and Information Technology, Minister Seyed Sattar Hashemi said the cyberattack occurred on Sunday, coinciding with the launch of Iranian satellites. He described the operation as a highly sophisticated assault designed to disrupt the systems of one of Iran’s telecom operators.

Hashemi said the cyberattack was carried out in two distinct phases and was fully contained. The first phase was managed outside Iran’s borders, while the second phase was neutralised domestically using indigenous technical capabilities.

“The fact that such a complex attack was controlled in two stages shows the resilience of our national infrastructure,” he said, adding that Iranian experts played a critical role in preventing serious damage.

The minister emphasised that despite extensive international sanctions, Iran’s knowledge-based production ecosystem remains active and effective, particularly in cybersecurity and information technology.

Iran has frequently reported cyber threats against its critical sectors, especially during sensitive political, technological, or scientific milestones, underscoring the continued importance of cyber resilience and national digital security.
