Israel’s financial institutions are on high alert as Iranian hackers have threatened to carry out a significant cyber attack on Friday.

In response, the Bank of Israel has convened a special preparedness meeting with representatives from banks, credit companies and other financial institutions, in cooperation with Israel’s National Cyber Directorate.

The threat comes from the Iranian Anonymous for Justice group, which has issued a 72-hour countdown. This warning follows two recent cyberattacks against credit institutions in Israel, SHVA and Credit Guard, which managed to disrupt credit transactions for a few hours each time.
