The US Cybersecurity and Infrastructure Security Agency (CISA) has issued a warning about a “significant threat” from North Korean hackers. The agency said the hackers, known as the Hidden Cobra group, have been targeting government, private sector, and critical infrastructure networks in the US and around the world.

The agency warned that the group has been using a variety of tactics, techniques, and procedures to gain access to networks, including spear-phishing campaigns, malware deployment, and network exploitation. The agency said that the group has been particularly active in targeting government networks and critical infrastructure, such as power grids, water systems, and financial institutions.
