Includes: 1) Samsung G600 Stealth firmware. These catchers work by forcing increase in signal transmission power in order to extract IMSI numbers and intercept communication. In UMTS networks, phones are additionally downgraded to GSM and its less secure ciphers. If a new IMSI will be needed, the whole process should be repeated. So monitor it, learn it's parameters (Cell ID, other unique identifying info). Stingray is the code name for an IMSI-catcher, which is basically a fake cell phone tower sold by Harris Corporation to various law enforcement agencies. Ability can intercept GSM, UMTS, LTE and CDMA networks. git as referenced in the project. It's more of an IMSI sniffer. Most of the time a IMSI catcher is fairly passive in that it wants to see RX/TX data and proxy it to the proper tower for full functionality as to make sure the user has no clue. Blocker of the selected cell phones (Mobile phone firewall), for selective or mass suppression of GSM/UMTS targets. Active scanning involves using an “IMSI Catcher” or virtual base transmission station (VBTS) (Frick, 2000). Description of Cell Spy Catcher (Anti Spy) This App will Help you in Detecting "IMSI Catchers" (also called "Fake Cell Towers" or "Stingrays").
