The government cited the recent hacks on Bank Sepah and cryptocurrency exchange Nobite as reasons to shut down internet access to virtually all Iranians.

Earlier this week, virtually everyone in Iran lost access to the internet in what was called a “near-total national internet blackout.”

At the time, it was unclear what happened or who was responsible for the shutdown, which has severely limited Iranians’ means to get information about the ongoing war with Israel, as well as their ability to communicate with loved ones inside and outside of the country.

Now Iran’s government has confirmed that it ordered the shutdown to protect against Israeli cyberattacks.

“We have previously stated that if necessary, we will certainly switch to a national internet and restrict global internet access. Security is our main concern, and we are witnessing cyberattacks on the country’s critical infrastructure and disruptions in the functioning of banks,” Fatemeh Mohajerani, Iran’s government spokesperson, was quoted as saying in a local news story. “Many of the enemy’s drones are managed and controlled via the internet, and a large amount of information is exchanged this way. A cryptocurrency exchange was also hacked, and considering all these issues, we have decided to impose internet restrictions.”
