FBI, DHS Issue Joint Cyberalert

The FBI and Department of Homeland Security (DHS) issued a joint alert, warning companies of the persistent threat of cyberattacks in critical infrastructure sectors, including nuclear, water and aviation.

The alert included technical details of the "tactics, techniques and procedures" used by hackers to infiltrate organizations, and defenses that can be used to protect against the hackers.

"DHS assesses this activity as a multi-stage intrusion campaign by threat actors targeting low security and small networks to gain access and move laterally to networks of major, high value asset owners within the energy sector," the agencies wrote in the alert, first issued Friday.

"DHS has confidence that this campaign is still ongoing, and threat actors are actively pursuing their ultimate objectives over a long-term campaign."

The alert did not specify the countries or specific actors that prompted the warning, but The Washington Free Beacon reported the attacks bore resemblance to those used by Russian hackers, according to private cybersecurity operatives.
