How to evaluate software security? (lemmy.ml)

Without going through the whole source code. You can just look up the information on the web, but how do you know whether to trust that information?

(Assuming no security audit has been listed on the website, or the audit seems outdated.)

The easiest way is to always use a DNS whitelist firewall on a external device on your network. It is a pain in the ass to manage that list, but you'll log and block every unexpected connection.

Otherwise, you can do a basic grep for "http" in the source, or even by scanning a binary for strings. This vector is easily mitigated by an attacker using encryption or a simple cypher, but it will catch a lot of script kiddies.
