A hacking group "sponsored" by Iran's government is launching disruptive cyberattacks against a wide range of U.S. companies, including healthcare providers and transportation firms, according to a cybersecurity alert published by the U.S. Homeland Security Department (DHS) on Wednesday.
The warning, jointly authored by the FBI and DHS' Cybersecurity and Infrastructure Security Agency, said the hackers were exploiting old software vulnerabilities in products made by Microsoft and Fortinet to break into victim computer networks. While the vulnerabilities were patched, some customers haven't updated their networks.
On Tuesday, Microsoft said in a blog post that it had observed six different Iranian hacking groups deploying ransomware since September 2020.
