ID Name Description
EX-0003 Modify Authentication Process Threat actors may modify the internal authentication process of the victim SV to facilitate initial access, recurring execution, or prevent authorized entities from accessing the SV. This can be done through the modification of the software binaries or memory manipulation techniques.
EX-0006 Disable/Bypass Encryption Threat actors may perform specific techniques in order to bypass or disable the encryption mechanism onboard the victim SV. By bypassing or disabling this particular mechanism, further tactics can be performed, such as Exfiltration, that may have not been possible with the internal encryption process in place.
PER-0004 Replace Cryptographic Keys Threat actors may attempt to fully replace the cryptographic keys on the space vehicle which could lockout the mission operators and enable the threat actor's communication channel. Once the encryption key is changed on the space vehicle, the SV is rendered inoperable from the operators perspective as they have lost commanding access. Threat actors may exploit weaknesses in the key management strategy. For example, the threat actor may exploit the over-the-air rekeying procedures to inject their own cryptographic keys.
IMP-0006 Theft Threat actors may attempt to steal the data that is being gathered, processed, and sent from the victim SV. Many SVs have a particular purpose associated with them and the data they gather is deemed mission critical. By attempting to steal this data, the mission, or purpose, of the SV could be lost entirely.
