The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Cellphone Spoofing
I would start with ss7 and IMSI catcher in particular. There is also a project on git hub that might give some more insights. There are a bunch of tutorials on how to set it all up on YouTube. But it all basic. I think Juilliard have to dive into the protocols themselves. Though maybe I don’t know something.

Car / House Burglaries: Can Ubiquiti network trace trespassers / thieves within AP network range?
But people are playing around with such things for educational purposes. Might be easier for some law enforcement officer to pull IMSI logs from the relevant time from providers... IANAL and don't know anything about US law.

RTLSDR or HackRF one - for scanning 2g 3g LTE
This project goes a decent job at passively observing 2G: https://github.com/Oros42/IMSI-catcher An RTL2832U dongle is enough to get started.

Security experts of Reddit: In this paper it is claimed that, for $1400, a device can be constructed that intercepts cellular data. Is this still the case?
Also, IMSI (actually, a randomised version (TMSI)) is sent in the clear over the air - see https://github.com/Oros42/IMSI-catcher https://en.wikipedia.org/wiki/Mobility_management#TMSI. IMEI should be encrypted as far as I remember. But that's not very useful to intercept anyway as it's just an indicator of the phone (and can be altered)

LTESniffer: An Open-Source LTE Downlink/Uplink Eavesdropper
For those interested in a more accessible LTE meta-data decoder check out https://github.com/JiaoXianjun/LTE-Cell-Scanner which can work with even cheap rtl-sdr dongles (for some things). It is a fork of an older https://github.com/Evrytania/LTE-Cell-Scanner

Detecting Fake 4G Base Stations in Real Time (2020) [pdf]
Having a quick look : I understand they only listen and never transmit, and just decode MIB and SIB1 => why do they require a sophisticated and expensive SDR such as bladerf ? I though an rtl-sdr would be able to decode MIB (and probably SIB, but I have a doubt there because maybe the location of those resource blocks would exceed the rtl-sdr's limited bandwidth... I would need to check, but anyway it seems https://github.com/JiaoXianjun/LTE-Cell-Scanner is able to decode SIB)
