This isn't spying and the US would not be the only country involved.
Carriers track their own subscribers' locations no matter which network they are on. Inter-carrier roaming agreements require this ability. So it appears the Saudis has a new use for it.
The increased focus on SS7 security actually increases reliance on inter-carrier PSI. PSI is sent to the last known serving MSC to retrieve the number of minutes since last network contact. This info is used to enable a velocity check against a network attached request coming from a new country. It's this type of check that combats SMS interception.
- neonate 7y agoI assume MSC is this: https://en.wikipedia.org/wiki/Mobile_switching_centre_server https://en.wikipedia.org/wiki/Mobile_switching_centre_server. What is PSI? Edit: thanks!

- dontbenebby 7y ago>This isn't spying Huh? Care to explain this odd take? Obtaining information about someone's location w/o their permission, by agents of a foreign power, seems pretty textbook spying.
