Iran says it foils cyberattack targeting internet providers
IRAN repelled a cyberattack on Saturday that disrupted the country’s internet services for an hour, a telecommunications ministry official said.
“At 11:44 (0814 GMT) a distributed denial-of-service attack disrupted the internet services of some mobile and fixed operators for an hour,” tweeted Sajad Bonabi.
A DDoS attack involves overwhelming a target’s servers by making a massive number of junk requests.
“Connections have returned to normal following the intervention of Dejfa shield,” Bonabi added, referring to Iran’s so-called digital fortress against cyberattacks.
He did not elaborate on the source of the attack.
Bonabi is a board member at the ministry’s Telecommunications Infrastructure Company, the sole provider of the country’s telecommunications infrastructure.
Internet monitor NetBlocks confirmed Saturday’s outage and said it was “consistent with a targeted disruption and no technical faults are evident at the present time.”
Iran said in December it had thwarted a “highly organized cyberattack” targeting its e-government infrastructure.
Telecommunication Minister Mohammad Javad Azari Jahromi described the attack as “really massive” and “state-sponsored.”
