The use of cell site simulators is still shrouded in secrecy. It’s not just the government who uses these to catch “bad guys”.

But a lot of really great research by the academic community, privacy advocates, and some of my colleagues has advanced our knowledge of how they work.

If you have an Android device, and you’re able to do so, the single most impactful thing you can do for your cellular privacy and security is to disable the “Allow 2G” setting in the mobile network settings screen (available on most devices shipped in the last couple of years). If you’re in North America it’s extremely likely there’s no legitimate 2g networks still in service from your carrier, and a downgrade to a 2g connection is a very common and easy mechanism for all sorts of privacy invading attacks.

It doesn’t come close to mitigating all risks posed by CSSs, but it’s an impactful start.

For years, these devices have elicited criticism from civil rights groups and legislators who argue that they violate Fourth Amendment protection against unreasonable search and seizure. The government insists it will only use this type of kit in line with existing rules and restrictions, but it appears that is not the case.
The Department of Homeland Security (DHS) Office of the Inspector General (OIG) looked at CSS deployment by the Secret Service and ICE and found, "Secret Service and ICE HSI [Homeland Security Investigations] did not always adhere to Federal statute and CSS policies when using CSS during investigations involving exigent circumstances."
