Zoom Conference scanner.
This scanner will check for a random meeting id and return information if available.
First try to see if there’s any prebaked version for the date: https://github.com/elcuervo/tangalanga/releases.
This versions already have a token ready to use.
Either way you can find the Windows, Linux and Mac version on Releases https://github.com/elcuervo/tangalanga/releases.
Download, uncompress and enjoy.
This are all the possible flags:
Unfortunately I couldn’t find the way the tokens are being generated but the core concept is that the
zpk cookie key is being sent during a Join will be usable for ~24 hours before expiring. This makes trivial to join several known meetings, gether some tokens and then use them for the scans.
Tokens can be sniffed after a join attempt to a meeting. This means that to “fish” a token you’ll need a setup that can sniff traffic and also spoof certificates.
Using Wireshark, Charles or any other of the ssl-proxying-capable tools out there will do the trick.
Tangalanga has a tor runtime embedded so it can connect to the onion network and run the queries there instead of exposing your own ip.
For any other system I recommend a VPN
