Collaborate Disseminate
I have a doubt regarding how to differentiate between subscribers belong to 2G/3G networks or 4G network?
I have no proof such as journals, however I have read some comments from some forums that are shown below:

In July we reported on the launch of the Hologram developer program that offered a free SIM card and a small amount of monthly cellular data for those who wanted to build connectivity into their prototypes. Today, Hologram has launched some new hardware to go along with that program.
Nova is a cellular modem in a USB thumb drive form factor. It ships in a little box with a PCB that hosts the u-blox cellular module, two different antennas, a plastic enclosure, and a SIM card. The product is aimed at those building connected devices around single-board computers, making it …read more

At Blackhat yesterday Ravishankar Borgaonkar and Lucca Hirschi revealed an attack on the security protocols underlying current 3/4g networks. Parts of the tech press are freaking out that it could allow a new generation of S… Continue reading How serious is the Borgaonkar/Hirschi attack on 3/4g cellular security
If you’ve been thinking of adding cellular connectivity to a build, here’s a way to try out a new service for free. Hologram.io has just announced a Developer Plan that will give you 1 megabyte of cellular data per month. The company also offers hardware to use with the SIM, but they bill themselves as hardware agnostic. Hologram is about providing a SIM card and the API necessary to use it with the hardware of your choice: any 2G, 3G, 4G, or LTE devices will work with the service.
At 1 MB/month it’s obvious that this is aimed at the …read more

Anyone who had a cheap set of computer speakers in the early 2000s has heard it – the rhythmic dit-da-dit-dit of a GSM phone pinging a cell tower once an hour or so. [153armstrong] has a write up on how to capture this on your computer.
It’s incredibly simple to do – simply plug in a set of headphone to the sound card’s microphone jack, leave a mobile phone nearby, hit record, and wait. The headphone wire acts as an antenna, and when the phone transmits, it induces a current in the wire, which is picked up by the soundcard. …read more

On reading about IMSI catchers, it is almost always mentioned together with MITM attacks, i.e. as if IMSI catchers are same as MITM.
But from my understanding, IMSI catchers and MITM are not the same thing:
IMSI catcher – a… Continue reading IMSI catcher vs MiTM attack
I teach lessons over Skype, but my internet isn’t very good and after a lot of attempts to improve it I’ve come to the conclusion that my ISP just isn’t able to provide me with reliable internet. I want to tether from my phon… Continue reading Make my computer think it’s on wifi when I hotspot 3G from my phone [migrated]
From what I understand pretty much all Intel CPUs produced since Sandy-Bridge have “secret” 3G capabilities in their IME (Intel Management Engine). This IME has full access to the memory bus and pretty much your whole computer and there is… Continue reading Privacy implications of Intel CPU’s secret 3G communication (Anti Theft 3.0)
Back the late 2000s, when netbooks were the latest craze, some models would come with an inbuilt 3G modem for Internet access. At the time, proper mobile Internet was a hip cool thing too — miles ahead of the false prophet known as WAP. These modems would often slot into a Mini PCI-e slot in the netbook motherboard. [delokaver] figured out how to use these 3G cards over USB instead.
It’s actually a fairly straightforward hack. The Mini PCI-e standard has a couple of pins dedicated to USB data lines, which the modem in question uses for communicating with the …read more
