One of Iran’s biggest government-run banks, Sepah Bank, was hit by a cyberattack on Tuesday, according to Iranian media. The Fars news agency reported that the attack caused trouble in the bank’s online services. However, the report also mentioned that normal operations were expected to resume within hours.

“A cyberattack targeted the infrastructure of Sepah Bank, causing disruptions to the institution’s online services,” Fars reported.

No information has been shared yet about who might be behind the attack.

Mobile phone ban for Iranian officials

Iran’s Cyber Authority has reportedly told government staff, security officials, and other workers to stop using mobile phones connected to public networks. This comes after rising concerns about Israel possibly using mobile phone tracking to locate important targets inside Iran.

An Israeli news outlet, Channel 12, claimed that the decision might be linked to fears that Israel has been tracking mobile phones to carry out assassinations, including those of nuclear scientists.

The Fars News Agency, which has ties to the Iranian military, said that Israel has used mobile tracking in past killings.

“Israel uses mobile tracking to assassinate individuals in Iran. It previously killed Ismail Haniyeh the same way in Tehran,” the outlet claimed.

It also warned that turning off a mobile phone may not stop it from being tracked. Officials were advised to switch to secure, anti-tracking devices.

After the report came out, a member of Iran’s parliament urged military and government figures to collect all mobile devices being used by themselves and those close to them.

Amid the ongoing tension between Iran and Israel, Yechiel Leiter, Israel’s ambassador to the United States, hinted that more secret actions might take place soon.

“There’s still a lot of things we can do,” he told Merit TV.

“We’ve pulled off a number of surprises, when the dust settles, you’re going to see some surprises on Thursday night and Friday that will make the beeper operation almost seem simple,” he added.

In a previous incident last September, Israel reportedly caused injuries to several Hezbollah fighters by blowing up thousands of their walkie-talkies and communication devices in a planned intelligence mission.
