Base transceiver stations (BTS) running the most common open source software products are vulnerable to attacks. The software for BTS stations is vulnerable to three separate attacks that can be used to ultimately hijack a cell tower. The vulnerabilities found could allow an adversary to remotely control the BTS transceiver module. Criminals could send GSM data bursts to the transceiver to enable a wide range of attacks, such as IMSI detaching, encryption downgrading and denial-of-service.”]
