In 2020, Zoom Video Communications came under scrutiny for marketing its "Zoom" software as a secure, end-to-end encrypted solution for video conferencing. Zoom's documentation claimed that it used "AES-256" encryption. Without source code, did we have to take the docs at their word?

Syscall tracing, packet sniffing, and core dumps are great, but they rely on manual execution which might not hit all the desired code paths. Fortunately, there are other forms of analysis available.
