urh VS sslstrip

>> or somewhat expensive and complex SDR

I don’t think that’s as accurate today as it used to be.

On the hardware side there are tons of options very cheaply available - iirc the flipper uses the c1100 (or a number like that) it’s a popular cheap chip and it’s well documented and interfaces easily with arduino.

More accessibly, lime mini SDRs are cheap but there’s quite a few alternatives too.

On the software side GNU Radio is free with decent tutorials - we’re not talking anything like blender levels of difficulty to adopt even if it is a complex domain.

Although on the more accessible side, urh is incredibly powerful given how easy to use it is https://github.com/jopohl/urh

I used the latter to tap into a 2 channel wireless bbq thermometer via a $10 rtl sdr and that was a breeze, an absolute walk in the park compared to when I reverse engineered the flysky telemetry system.

you should check out Universal Radio Hacker

Check out URH.

URH can read flipperzero sub files and can export from wav to sub... https://github.com/jopohl/urh

Throw the recording at UniversalRadioHacker and see what it does with it!

I dont have much knowledge on decoding a signal from scratch but try URH - universal radio hacker here. It might be able to do what you need.

It's useful for transmitting digital RF signals to control household stuff, eg. ceiling fans or whatever. You'd want to also look into rtl-sdr and Universal Radio Hacker.

Tried tool https://github.com/jopohl/urh and it does not get too much information. I am expecting to find something similar to wireshark - it can detect protocols in traffic and highligh different kind of fields in packet headers.

Another option might be to try something like sslstrip to strip off the TLS layer so you can point your tools at the stripped-off/non-TLS endpoint. Probably non-trivial to get this old code working on any system though, let alone a Jetson: https://github.com/moxie0/sslstrip

sslstrip - Demonstration of the HTTPS stripping attacks.

Yeah. And for anyone unaware, this technique, SSL stripping, was made well-known (and arguably pioneered?) by Moxie Marlinspike of Signal with his tool sslstrip back in 2011: https://github.com/moxie0/sslstrip. I believe that's what he was most famous for before Signal.

Once the connection has been intercepted, the attacker can use a tool such as sslstrip to disable all HTTPS redirects and change https:// links to unencrypted http://.

E' possibile, per quanto molto meno facile. https://github.com/moxie0/sslstrip per esempio. Ci sono anche altre tecniche che si basano sulla manipolazione delle richieste di DNS e cose simili. Sicuramente molto piu' facile da notare e ordini di grandezza piu' complesso di HTTP, che è assolutamente triviale.
