IRLeaks, a freelance hacking group aiming to extort companies and countries, was likely behind the cyberattack on Iran's banking system in August, which industry analysts called "the worst" the country had ever experienced, according to POLITICO.
The attack, which some suspected may have been the work of Israel and the United States due to their conflicts with Iran, was reportedly resolved with the payment of at least $3 million by an Iranian entity to prevent the breached banking data from ending up on the dark web.
The Iranian government never officially acknowledged the attack, though some anonymous Iranians took advantage of the attack and subsequent difficulties in withdrawing money to protest the regime with signs saying that the money was stolen and used for foreign wars.
