"DHS finds suspected phone spying in Washington For the first time, the U.S. government has publicly acknowledged the existence in Washington of what appear to be rogue devices that foreign spies and criminals could be using to track individual cellphones and intercept calls and messages... In a March 26 letter to Oregon Sen. Ron Wyden, the Department of Homeland Security acknowledged that last year it identified suspected unauthorized cell-site simulators in the nation’s capital. The agency said it had not determined the type of devices in use or who might have been operating them. Nor did it say how many it detected or where..." https://www.federaltimes.com/federa...s-finds-suspected-phone-spying-in-washington/ "Feds: There are hostile stingrays in DC, but we don’t know how to find them There’s also “anomalous activity”—probably stingrays—in other US cities, too..." https://arstechnica.com/tech-policy...-use-of-stingrays-is-a-real-and-growing-risk/ "...DHS said they have not determined the users behind such eavesdropping devices, nor the type of devices being used.

Funny. When I've read about IMSI-catchers around the US, I've assumed that they were operated by US agencies. So yes, could be spies too. Very funny.
