The individuals and companies allegedly targeted over a dozen US companies and government entities through spear phishing and malware attacks.

The US Treasury Department stated that these actors aim to destabilize US critical infrastructure and cause harm to citizens.

The US imposed new sanctions on Iran in response to its support for anti-Israel proxies in the Middle East and military aid to Russia's war in Ukraine.

This is the latest in a series of sanctions against Tehran by the US and its allies.

The sanctions were announced in response to Iran's large-scale attack against Israel earlier this month, which was a response to an April air strike on an Iranian consulate in Damascus, believed to have been carried out by Israel, resulting in the death of seven members of the Islamic Revolutionary Guard Corps, including two generals.

The US imposed sanctions on a Thailand-based firm and indicted four individuals for potential Iran sanctions violations and cyber activity targeting US entities.

The firm, which is jointly owned by Iran's National Petroleum Company, was fined $20 million for processing over $300 million in wire transfers.

The individuals were also accused of processing transactions worth close to $1 billion for Iranian entities.

The Department of Justice and FBI are involved in the investigation.
