With the new Law on Intelligence that may be used by the intelligence services of the IMSI-Catcher soon do you expect to make you suck your mobile even if you are innocent.
Just as you are ready for a demonstration of a supervised company, or neighborhood where would hide dangerous terrorists ... and bam!
Apparently, these devices arent far 100 000 ... But I have seen, done by hackers who had brought a little lower, but that cost much less. Remember, an IMSI Catcher is a device that fits in a suitcase (which is transportable) and posing for GSM relay antenna.
Your phone connects top and IMSI Catcher then transfers your calls, SMS, data connections to the real antenna the corner.
But of course, in the meantime, all your data has been intercepted. So as you are innocent and you need to complain to the competent authority if you are the subject of a monitoring or spying by a crafty one, here's a little app for Android will help you.
This is for Android IMSI-Catcher Detector , a small application that will tell you the level of monitoring which is the subject your phone. For this, Android IMSI catcher detector uses several techniques:
Check the consistency of information returned by the towers
Monitoring signal strength
Detection of femtocells
Consistency of LAC / Cell ID
Checking the cell information of the Neighborhood,
Search SMS Silent
Blocking silent installations
Well it sucks a little battery , but it will allow you to flush out those who seek your privacy and complaints (ahaha).
Anyway, now you know!
