So much disinformation as usual and the usual 'Government are doing it' crowd are out in force I see. Not saying that some of them may not be in
place by the Government, but it's unlikely as they only deploy these types of systems for very specific reasons. If they want access to your phone
calls, emails, etc then they go direct to the service providers, did no one else read the recent leaks and apply this with common sense?
1) The headline is misleading (not your fault OP) - it implies they are only spying on Android devices - not so, it was just that an Android device
which you can install IMSI Catcher Detector software
on was used to find them.
A more accurate headline would be "Dozens of fake cell phone towers discovered eavesdropping on phones" - but the person who wrote it probably
didn't think about the possibility of wrong interpretation of the original sentence or is just an Apple fanboi.
2) These 'towers' which are more likely to be small femtocell sized homebrew devices can be easily constructed by someone who can read, understands
Linux, has some mediocre programming skills and any amount of money ranging from about $50 to many thousands.
The simplest form without going into too much detail utilises a few certain models of a particular brand of phone loaded with custom baseband firmware
which communicates directly to a PC running software under Linux.
You can also use other radio interfaces like USRP or HackSDR, depends on what you want to do exactly but the $10 redundant phones (which are harder to
get hold of now for obvious reasons) are the cheapest route in. It certainly does not cost a lot of money and is not in the realms of Government only
This is an increasing problem with relatively petty criminals acquiring personal data for the various usual purposes.
This uses 2G and GPRS for data, I am not aware of any easy solution for 3G/4G - hence why in the article it notes that phones are forced down to a 2G
So sorry to burst the 'governement did it' crowds bubble, but a little reading around will show you what I'm saying is 100% correct and easily
achievable. The only 'conspiracy' here is that the cellular companies probably don't make a big of a deal about it as they should informing people
and replacing the old redundant network a lot quicker.
Did you know for instance, using $20 of hardware, a Linux PC and a 2TB hardrive containing **something I'm not going to advertise** ANYONE can easily
listen to telephone calls and receive SMS messages from their local 2G cellular towers? It's not actually hard anymore.
Don't ask me for specific information, it's against T&C and I'm not interested in helping anyone hack anything. If you ignore this you will be
ignored I'm afraid, I'm only reluctantly writing this at all when I normally avoid these subjects because I'm astounded by the lack of knowledge
people are displaying when it is so readily available, and it's a very important subject to be aware of.
