Student sentenced to jail for showing TETRA insecurity

Added by laforge 10 months ago

According to some news report, including this report at softpedia, a 26 year old student at the Faculty of Criminal Justice and Security in Maribor, Slovenia has received a suspended prison sentence for finding flaws in Slovenian police and army TETRA network using OsmocomTETRA.

If a TETRA network (like any other network) is configured with broken security, then the people responsible for configuring and operating that network are to be blamed, and not the researcher who invests his personal time and effort into demonstrating that police radio communications safety is broken. On the outside, the court sentence really sounds like "shoot the messenger". They should instead have jailed the people responsible for deploying such an insecure network in the first place, as well as those responsible for not doing the most basic air-interface interception tests before putting such a network into production.

According to all reports, the student had shared the results of his research with the authorities and there are public detailed reports from 2015, like the report (in Slovenian) at https://podcrto.si/vdor-v-komunikacijo-policije-razkril-hude-varnostne-ranljivosti-sistema-tetra/.
