Someone can retroactively CHANGE the rules and suddenly something legal you did in the past that is on record, gets you into trouble. .

​@@xantiom Yeah it's a well known vulnerability in these situations. Networks do decent amount of blocking of bad actors, but if someone really wanted to route your calls, listen in, intercept your SMS, locate you, they can. It's pretty crappy. It's why OTT/VoIP are significantly better alternatives. It's why Apple should have been genuine implementing RCS instead of using the Universal Profile which is not encrypted. Furthermore, Apple should just work with Google to expand iMessage. It sucks. Cellular networks are very old technology, often very outdated.

I mean, that's what we already have, we've just put semantic meaning to certain digits which have created these problems.

Though our country code is 1 so... it's usually not a big deal to. I'd imagine in places with longer country codes they'd opt to ignore it.

[@Pan_Galactic_Gargle_Blaster]

One of the things that I feel is never brought up when the "why can't we just dump 2G and 3G networks?" argument is provided, is that 4G and 5G have much lower broadcast ranges than 2G and 3G. This is just a function of signal frequency, with 2G having maximum range of up to 50 miles and 5G having a max range of 1000-2000ft. Higher frequency, low amplitude signals travel much shorter distances, so dumping support for "legacy" networks is near impossible in more rural areas until GSM satellite networks are available and affordable.

[@ChristianHawkins123]

This is only partly right. We have assigned different frequencies to different evolutions of cell technology. When GSM started, we used the lowest available frequencies, (depending on location) around 900 MHz, then we added 1800/1900 to 2G. When 3G came, 2100 MHz was used for it. But, in theory, you can run 3G, even 4G and 5G on 900 MHz, and you would benefit from very similar range characteristics as 2G. The problem is however, that those frequencies are in use by 2G, and you can't use multiple generations on the same frequency. So as long as 2G and 3G exist, we can't reuse these high range frequencies for 5G. T-Mobile USA has introduced band 71 in the late 2010s, which is 4G at 600 MHz, providing better coverage than 2G. tl;dr Not the 2G/3G/4G/5G determines the range, it is actually what frequencies are used by the operator. because of legacy networks, the ones reaching further are currently in use by SS7 technologies.

people, "Nothing to hide, nothing to fear" IS accurate. problem is, most if not all people HAVE things to hide. like the passwords for my bank, or the hours of the day when im not in my home. that quote is soo dumb because it ignores such things

[@SteakandChains]

Great video! This was my whole world when I was in the military and for a contractor when I got out. The reason why it doesn’t always work is because of network registration. Your victim’s phone needs to be far enough away on a neighbor node for the routing to your phone to work. I miss that life.

It would be nice if there were a website that lists which mobile networks block which SS7 messages that the researchers suggest should be blocked. I assume it must be possible to obtain this data for someone (like the researchers) with the means to test it.

2G has been shut down for ages in Australia and 3G is being shutdown now. It can be done.

UK has a legal deadline of 2033, so there's plenty of places dragging their heels. Thankfully most carriers here have agreed betweem themselves to have theirs offline by the end of this year, with Vodafone already cutting theirs.

[@EricGerlachCa]

Unfortunately, it doesn't matter. Your Australian telcos will still be supporting SS7 to interoperate with international carriers that still support 3G.

[@rossstewart9475]

@@EricGerlachCa What it does do is allow telcos to reduce their circle of trust, which will at least help reduce the incidence rate in regions where 2g/3g is disabled. Not a fix, but still a step forward.

[@Justice4Bob]

My area in the UK have shut down 3g, and the 4g signal is now sh%% because it can't cope with all the extra traffic

2g is still active in Australia. Not for regular calls (to my knowledge) but it's used for nb-iot (narrow band internet of things) communications for sensors and devices that don't need much bandwidth to be able to communicate.
