(CNN) The Department of Homeland Security on Saturday updated its terrorism threat advisory system following the US airstrike targeting a top Iranian general and is warning of the potential for Iranian cyber attacks. Acting Homeland Security Secretary Chad Wolf issued a new National Terrorism Advisory System bulletin in the wake of the drone attack, which killed the head of the Revolutionary Guards' Quds Force Qasem Soleimani. The bulletin details the attack and potential Iranian threat , including previous plots against US infrastructure and cyber targets. "Iran maintains a robust cyber program and can execute cyber attacks against the United States," reads the bulletin, which expires January 18. Wolf maintained in a statement and the advisory indicates there is "no specific, credible threat against the homeland."
