H-ISAC TLP White Threat Bulletin Strengthening Cybersecurity of SATCOM Network Providers and Customers

On March 17, 2022, the United States Cybersecurity and Infrastructure Security Agency (CISA) and the Federal Bureau of Investigation (FBI) released a joint cybersecurity advisory (CSA) to highlight possible threats to US and international satellite communication (SATCOM) networks. Successful intrusions into SATCOM networks could create risk in SATCOM network providers’ customer environments.

Given the current geopolitical situation, CISA’s Shields Up initiative requests that all organizations significantly lower their threshold for reporting and sharing indications of malicious cyber activity. To that end, CISA and FBI will update this joint Cybersecurity Advisory (CSA) as new information becomes available so that SATCOM providers 

and their customers can take additional mitigation steps pertinent to their environments.

CISA and FBI strongly encourage critical infrastructure organizations and other organizations that are either SATCOM network providers or customers to review and implement the mitigations outlined in this CSA to strengthen SATCOM network cybersecurity. Health-ISAC is releasing this report for your increased security awareness.
