In 2022, a significant cyberattack targeted the KA-Sat consumer satellite broadband service, affecting the satellites and disrupting broadband services. Such a breach highlights the vulnerabilities and potential risks to national security posed by cyber threats to key satellite infrastructure. The severity of these disruptions in space has implications that can transcend beyond military communications, impacting various aspects of civilian life and the expansive global market that relies on satellite technology. The US military's Commercial Augmentation Space Reserve (CASR) initiative aims to improve resilience against such threats by partnering with the commercial space industry.
