SS7 is vulnerable to attack. However, the types off attacks on the video don’t affect Signal as it requires a pin. (Make sure you set your pin to something strong and secure)

It’s 30 minutes. Anyone have a quick summary?
Mobile networks are awful and are very easy to spy on.
But the video is worth every minute.
I did watch it in the end after your recommendation, and it was interesting. Thanks!

I don’t particularly like Linus, but he was bearable in this video. As someone who assumed this was a SIM swap, I was genuinely as confused as he was playing it up when he was able to place calls but not receive them. That was really interesting.
Linus is great. Sure he has his flaws but of all the flawed people he doesnt have horrible ones.
Birds of a shit-feather flock together.
I have seen Linus straight up lie about things and distort benchmarks to make it seem like companies they get money from make better products than they do. Fuck that guy.
SS7 protocol for 2G and 3G is vulnerable to man in the middle attack, easy to spy on people with. They use a walled garden approach al the primary defence mechanism and you can gain access through in for the low low price of couple of thousands of USD.
Couple of exploits are intercepting or monitoring calls and texts and triangulating position by checking what cell towers are in range.
I remember the analog days where a few keystrokes on an Ericson phone were all you needed to start listening to private conversations on the cell tower you were connected to.
My rule of thumb that grimaces in the thumbnail mean the video is playing on emotions instead of facts (i.e. is crap) has another match.
I’ve never had a cellular provider for this reason among others. Here is NBTV’s video with some alternatives to directly having a SIM card, which I combine with MySudo to get phone numbers as well.
What’s your experience with using mysudo/voip numbers in terms of services accepting them (e.g. Google)? And socially, can you do regular calls with these numbers? Any audio delays?
Silent.link is also worth considering. I think it also works for people in the EU.

(copied my comment for the top context comment but the other person hasn’t answered yet, wanted to get some info on these kinds of services first hand)
Haven’t used it [silent.link] myself. All I know is that all (or some) plans they offer include only incomming-calls, not outgoing. But good point you make about delays. That’s important. Haven’t thought about that myself.
I’m not too versed in it myself yet. You were asking about these services in general, right? Since you wrote “voip numbers”. I’ll keep tabs on your other comment then
Right. I’m considering trying out voip numbers but concerned about these disadvantages. Not that I call much anyways, just don’t want to make a frustrating calling experience more frustrating lol
Super Saiyan 7 is actually invincible.
The hack is Super Saiyan God
He says nothing about the PIN, so I don’t think that is what protects Signal as OP writes. It simply doesn’t rely on SS7.
You only type your PIN into Signal about once a month.
I found it confusing. Did he explain how the IMSI number is obtained?
Towards the end he said there was a special “interrogation” command that would reveal the IMSI but that loophole is now closed.
Would GrapheneOS with default settings be immune since 2G is disabled and networks don’t have 3G anymore?
No as ss7 is still widely used for compatibility
Can everyone please stop linking to Linus? He’s a YouTube huckster.
For one this isn’t a video by LTT.
Secondly not everyone hates LTT like you do
