I am looking over the IMSI Catcher metric on this page:
... and I think it's very interesting that many of these measurements could be taken without a mobile phone - perhaps with just a SDR device and GR-GSM and wireshark.
For instance, am I correct that every single one of the "A" metrics and also the K1 metric is all based on information that is broadcast, unencrypted, on the BCCH ?
If the registration timer is also broadcast on BCCH unencrypted, then metric "T1" is also available to a SDR with wireshark.
Finally, I wonder about R1.
F1 (Few paging requests) is obviously available to an SDR, although I see it was removed from the criteria...
Am I correct ? Can we determine a lot about the IMSI catcher score with just a SDR ?
