Iranians saw their access to Instagram, one of the few Western social media platforms still available in the country, disrupted on Wednesday following days of mass protests over the death of a woman who was detained by the morality police.
NetBlocks, a London-based group that monitors internet access, reported widespread disruptions. Witnesses inside Iran, who spoke on condition of anonymity out of security concerns, said they were unable to log on using mobile phones or home connections.
There was no immediate comment from Iranian authorities on the disruption to Instagram, which would limit the ability of protesters to organize and share information.
Iran already blocks Facebook, Telegram, Twitter and YouTube, even though top Iranian officials use public accounts on such platforms. Many Iranians get around the bans using virtual private networks, known as VPNs, and proxies.
In a separate development, the website of Iran’s Central Bank was briefly taken down on Wednesday as hackers claimed they had targeted the websites of several Iranian state agencies. Later, the official websites of Iran’s president and supreme leader were down.
The apparent cyberattack came amid days of protests over the death of a woman who was detained by the country’s morality police for allegedly wearing her Islamic headscarf too loosely. It also came hours before Iran’s President Ebrahim Raisi addressed the United Nations General Assembly.
Central Bank spokesman Mostafa Qamarivafa denied that the bank itself was hacked, saying only that the website was inaccessible because of an attack on a server that hosts it, in remarks carried by the official IRNA news agency. The website was later restored.
The Culture Ministry’s website was also unavailable as of Wednesday afternoon.
Hackers linked to the shadowy Anonymous movement said they targeted other Iranian state agencies, including state TV and the office of the presidential spokesman.
Iran has been the target of several cyberattacks in recent years.
In February, dissident hackers put up an anti-government message on a website that streams state television programming. Last year, an online group released video footage from inside Iran’s notorious Evin prison that it claimed to have acquired through hacking.
Later that year, a cyberattack crippled gas stations across the country, creating long lines of angry motorists unable to get subsidized fuel for days.
Messages accompanying the attack appeared to refer to Iran’s Supreme Leader Ayatollah Ali Khamenei. Other attacks, which Iran has blamed on Israel, have targeted its nuclear programme and industrial sites.
Iranians have been protesting for days over the death of Mahsa Amini, a 22-year-old who was arrested by the morality police last week. The police say she died of a heart attack and was not mistreated, but her family has cast doubt on that account, saying she had no previous heart issues and that they were prevented from seeing her body.
The UN human rights office says the morality police have stepped up operations in recent months and resorted to more violent methods, including slapping women, beating them with batons and shoving them into police vehicles.
Amini’s funeral on Saturday sparked protests in the western Kurdish region, where she was from, which eventually spread across country and reached the capital, Tehran. The protesters have clashed with police and chanted against the Islamic Republic itself.
Raisi has called for an investigation into Amini’s death. Iranian officials have blamed the protests on unnamed foreign countries that they say are trying to foment unrest.
Iran’s Supreme Leader Ayatollah Ali Khamenei made no reference to the protests in a meeting on Wednesday with veterans of the 1980s Iran-Iraq war.
Iran has seen waves of protests in recent years, mainly over a long-running economic crisis exacerbated by Western sanctions linked to its nuclear programme.
The Biden administration and European allies have been working to revive the 2015 Iran nuclear accord, in which Iran curbed its nuclear activities in exchange for sanctions relief, but the talks have been deadlocked for months.
In his speech at the UN, Raisi said Iran is committed to reviving the nuclear agreement but questioned whether it could trust America’s commitment to any accord.
Iran insists its nuclear programme is for peaceful purposes. It began ramping up its nuclear activities after then-President Donald Trump unilaterally withdrew from the 2015 agreement, and experts say it now likely has enough highly-enriched uranium to make a bomb if it chooses to do so.
