How To Get Arrested In 30 Minutes: Cracking A GSM Capture File In Real-time With AIRPROBE And KRAKEN

My GSM cracking content has been getting quite a lot of attention lately. Previous videos of mine relating to this topic were only boring screen recordings with no real explanation on what steps are required to crack the A5/1 stream cipher and decrypt GSM traffic by obtaining the Kc value.

I was bored one day and decided to present a live-style workflow of how hackers and security researchers 'crack' 2G cellular communications in real-time. Be warned that if you don't have an interest in cryptography or cellular network security, you might find this video rather boring.

I make a few mistakes in the video that I can't be bothered editing out. But they are not critical, just myself misreading a number at the 10 minute mark somewhere, and saying the wrong name of a software tool at 17 minutes.

Additionally, l am not a GSM technology engineer, nor a cryptography expert. I do my best to explain these concepts in a simple and easy to understand way. But due to my limited knowledge of these subjects, it's possible that some of this information may be incorrect or lacking context.

However, this video will still allow you to crack a real GSM capture file if you are able to follow along with my flip-flopping style of presentation. Haha. But please, only replicate this tutorial on GSM data that originated from YOUR OWN mobile phone. Do not attempt to decrypt private telecommunications from any other cellular subscriber, EVER.

Thanks for watching!

"Educational Purposes" are the only 2 words keeping this video & channel save

[thebitterbeginning]

I love how governments declare it highly illegal to intercept private internet traffic, yet their violation of that law is a MUST, a requirement. We are pets, we are their property, we are owned.

Studied the video to find out whether or not she actually was cheating on me, ended up getting headhunted for a cyber security role. Thanks dude. Thumbs up.

[FeralFlare]

Citizens: "THIS IS ILLEGAL!"

Intelligence branches: "NOT FOR ME!"

I'm not sure why you say that this is boring content, if you actually wanna learn something this is the content that's needed, I'm not here for tiktok speed content. I really appricate this type of content it's really good.

Funny story from Norway. A newspaper, Aftenposten, found IMSI catchers all around Oslo, the capital of Norway. They started following the case, and eventually called up the security police. And suddenly they stopped writing more articles about it.

[ashrimpcouldnotdothis]

youtube is recommending videos to me that'd put me on a list now

[PetrolSniffer]

Crazy how hackers are capable of this possessing this much knowledge and coding jargon in the hacking/cracking repertoire. Not only is it interesting but it really is a testament to software skill when it comes to using a computer.

Great and informative stuff, hope to see more vids like this!

[DDBAA]

I've been waiting for a channel like this for a couple years.. I bought a SDR and I couldn't find a way to learn beyond basics that held my interest. We're there. Thanks.

This video is the reason why text and call encryption formats should be standard on all devices by default. SMS is a transparent messaging system and works with all devices with a cellular network but it's too transparent since anybody can look and sniff out those messages and calls through methods like this

[SleazyRoseWalker]

I don't understand any of this, but still i find it highly fascinating. To me this is like looking into a bizarre realm where my understanding of what i see is nil

[jacobanderson]

Get arrested in under just 1 minute by punching a police officer.

[kormannn]

30:25 I heard the knock-knock sounds. Glad they're so polite to let you finish this video for extra five minutes.

[Pseudonaym]

10/10. Highly recommended. Writing this whilst on Death Row. Worked a charm.

[mojotmn]

I was expecting FBI craking your door open at the end of the video :)

[colly]

Everyone talks about sniffing packets, but no one ever discloses what they smell like...

[crylune]

This is why I tell privacy freaks that if you own a SIM card you’re screwed anyway

[raulgalets]

this officer, this is the video I watched

[kotopiu]

idk what the fuck is going on but this dude seems to know what hes talking about so imma like the video.
