C3Voc (CCC video operation center) does not want the raw stream to stay online, the edited version will appear soon online here: https://media.ccc.de/v/rc3-11511-watching_the_watchers_-_how_surveillance_companies_track_you_using_mobile_networks https://media.ccc.de/v/rc3-11511-watching_the_watchers_-_how... I have watched the stream, it consists of an overview of security holes in SS7 and newer protocols. The vulnerabilities are either blocked by the ISP, or not blocked but require the attacker to have a lot of information about the target. An exception to this is https://simjacker.com/ https://simjacker.com/ which is unlikely to be blocked and only requires the full phone number of the victim. An interesting point in the talk was the missing "economy of scale" in the pricing system of the surveillance companies. If you want to spy on more victims, the costs rises exponentially, because it becomes more likely that the attacker will be blocked by the ISP.

There was an article here a few weeks ago about how these surveillance companies then sell this information to US law enforcement agencies. Though the government would need a warrant to compel these companies to turn over this information, they have decided they don't need permission to buy information on the public market. A free market surveillance state is acceptable. No clue if this presentation covers this, as the video is still unavailable.
