"CISA, FBI Warn Critical Infrastructure of SATCOM Cyber Threats"

The US Homeland Security Department's Cybersecurity and Infrastructure Security Agency (CISA) and the Federal Bureau of Investigation (FBI) released a joint advisory warning critical infrastructure organizations about cyber risks associated with satellite communication (SATCOM) networks. SATCOM networks are used across all sectors for voice and data communication. Therefore, CISA and the FBI are urging SATCOM network providers and customers to stay vigilant against cyberattacks on SATCOM networks, which could lead to the disruption of network environments. For example, hackers targeted the SATCOM provider Viasat in February, disrupting network access in Ukraine. Viasat is also a defense contractor for the US, and so it is used across US critical infrastructure. CISA and the FBI call on SATCOM providers and customers to enable Multifactor Authentication (MFA), enforce the principle of least privilege, and inspect trust relationships with IT service providers. The agencies pointed out that threat actors often abuse the trusted relationships between providers and their customers in order to access data. Organizations are also encouraged to monitor network logs, implement robust patching practices, maintain a cyber incident response plan, and more. This article continues to discuss the joint advisory released by CISA and the FBI warning critical infrastructure organizations of SATCOM cyber risks.
