A set of five security vulnerabilities in the Terrestrial Trunked Radio (TETRA) standard has been disclosed, potentially impacting sensitive information in government entities and critical infrastructure sectors.
Discovered by Midnight Blue in 2021 and collectively named TETRA:BURST, these vulnerabilities may allow real-time decryption, message injection, and user deanonymization. Despite no evidence of exploitation to date, the risks to TETRA-based radios, utilized in over 100 countries and controlling essential systems like power grids and railways, call for immediate action to address these serious issues.
TETRA:BURST, discovered by Midnight Blue, includes an intentional backdoor, leading to concerns about potential exposure of sensitive information in government entities and critical infrastructure sectors.
Despite no confirmed exploitation so far, the vulnerabilities enable real-time decryption and message injection, posing a significant threat to TETRA-based radios used widely in essential systems like power grids and railways. Immediate attention is crucial to protect against potential attacks and unauthorized access, given the severity of these flaws.
Midnight Blue’s disclosure of five security vulnerabilities, including a potential intentional backdoor, in the widely used TETRA standard raises alarm for government entities and critical infrastructure sectors.
These vulnerabilities may enable real-time decryption, user deanonymization, and message injection, necessitating swift action to address the risks. While no evidence of exploitation exists to date, the serious implications of TETRA:BURST demand immediate remediation efforts to safeguard sensitive information and essential systems.
