My female housemate recently had a stalker who was a 24-year-old computer geek. He was constantly showing up where she was and seemed to know what she was doing. SHE had previously used a tracking program on her ex-husband which she installed on his cell phone which would give her his location, record his calls, voicemails and texts (she showed this to me 3 years ago) so she decided to see if her stalker had done this to hers (they were a couple for about a week).
Anyway, she takes her phone to another computer geek that she knows. He goes through it completely; there is a program that had been installed REMOTELY. Apparently if they have the phone number, and the name of the service this can be done even by civilians (military has had the tech for years). He was able to find the program and install a block (that I'm sure can eventually be bypassed). But WOW! If a 24 year old geek civilian can do this, surely LE can, thought the legality is definitely suspect. Oh, and this was a burner phone through Boost Mobile.
SO, here are some COMSEC recommendations for ALL. LE, crazy clients or suspicious wives (or suspicious husbands to be P.C.) could somehow gain access this stuff. If you have a computer geek friend that you trust, have them check over your phone every so often. If you are able to, replace your entire phone every 3-6 months and get a new number. May not make you completely safe, but don't make it easier for THEM.
I thought I was done with this shit when I retired from the military!
It was so much easier when we used street corners.....
BE SAFE OUT THERE
