“Previous homeland-based plots have included, among other things, scouting and planning against infrastructure targets and cyber enabled attacks against a range of U.S.-based targets.” reads the bulletin. “Iran maintains a robust cyber program and can execute cyber attacks against the United States. Iran is capable, at a minimum, of carrying out attacks with temporary disruptive effects against critical infrastructure in the United States.”

During the weekend, a group of Iranian hackers claimed to have breached the website of a US government agency, the Federal Depository Library Program, vowing revenge for the killing of commander Qasem Soleimani.
