OpenBTS (Open Base Transceiver Station) is a software-based GSM access point, allowing standard GSM-compatible mobile phones to be used as SIP endpoints in Voice over IP (VoIP) networks. OpenBTS is open-source software developed and maintained by Range Networks .
A major problem with self-service password reset inside corporations and similar organizations is enabling users to access the system if they forgot their primary password. Since SSPR systems are typically web-based, users need to launch a web browser to fix the problem, yet cannot log into the workstation until the problem is solved.
Even if mobile phones are able to use 3G or 4G (which have much stronger encryption than 2G GSM), the base station can downgrade the radio communication to 2G GSM and specify A5/0 (no encryption). [20] This is the basis for eavesdropping attacks on mobile radio networks using a fake base station commonly called an IMSI catcher.
