According to a statement by the Iranian Parliament, the websites of the Parliament and Khane Mellat (ICANA.ir) news agency were hacked and became unavailable since Tuesday morning due to a cyberattack.
The statement said the scale of the cyberattack is under investigation by expert technical teams.
A hacking group called “Uprising till Overthrow,” affiliated with anti-Iran terrorist group, Mojahedin-e Khalq Organization (MKO), claimed responsibility for the attack. Iran considers the MKO a terrorist organization.
In a statement on its Telegram channel, the group claimed it hacked 600 servers affiliated with Iran’s Parliament and released hundreds of pages of hacked material on its Telegram page.
The Parliament’s statement said that the initial investigation shows that some documents released by the hackers have been fabricated.
The cyberattack took place less than three weeks before Iran goes to the polls to elect a new Parliament on March 1.
Websites linked to Iran’s government and affiliated media outlets have suffered several cyberattacks over the years.
A December cyberattack disrupted fuel sales at 60 percent of Iran’s petrol stations for weeks before services were fully resumed.
