(If you don’t know what CDMA is, you may want to start here.)

Vulnerabilities for CDMA operators are very similar than those found on GSMA networks. CDMA signalling also use SS7, just a different flavor of it.
Our CDMA penetration test is currently in R&D and we are looking for CDMA networks interested in this subject to serve as initial test targets.

If you are a CDMA network concerned about security vulnerabilities over the signaling interface, please contact us.
