IMSI-Catcher of the new generation:
Also known as: Hailstorm’s “Stingray”, Rayzone’s “Piranha”
They all have the GSM IMSI-Catcher features, plus new SS7, UMTS/LTE features
I want to compare the two devices and find out if there is a alternative method for all modes of operation with a 2.0 catcher.
1. The catching of IMSIs is much easier with LTE and so is the rest of the methods that are used.
2. The GSM features remain as a fall back, if the SS7 attack doesn’t work for example.
3. The possibilities of manipulating the firmware are more advanced than in 2G.
Details about SS7 requests and messages.
