with general <a href="https://mace.lol/tags/devops" rel="nofollow noopener noreferrer" target="_blank">#devops</a><span> stuff (containerisation and networking mostly) in my free time, a lot of my

Max Maass :donor:<p>Last week, I finally finished my writeup of a vulnerability based on a misuse of <a href="https://infosec.exchange/tags/Cryptography" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Cryptography</span></a> that we found a while back in a penetration test. It's my favorite vulnerability so far, as it relies on abusing basic properties of unauthenticated encryption and shows, in a real-world scenario, how such seemingly theoretical issues can compromise an entire system. In the end, it's a teachable moment about both cryptography and secure software architecture.</p><p>I had the draft lying around for more than a year, but reading the articles by <span class="h-card" translate="no"><a href="https://furry.engineer/@soatok" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@<span>soatok</span></a></span> finally reminded me that I should really wrap this up and post it.

Fiona :transbian: :autism:<p><span>Since I just checked again for a lemmy post and verified that my complaints are still current:<br><br>I explicitly recommend against the use of </span><a href="https://mastodon.social/@threemaapp" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@threemaapp@mastodon.social</a> as a messenger because of their bad <a href="https://blahaj.zone/tags/encryption" rel="nofollow noopener noreferrer" target="_blank">#encryption</a><span>.<br><br>I make this recommendation as a professional cryptographer who holds a PhD in that field and give explicit permission to be quoted on it.<br><br>The reason for this recommendation is that Threema’s End-to-End encryption offers no forward- or backward secrecy of any kind. This follows directly from the protocol description they themselves publish in their own whitepaper, so if this is a wrong claim, their own publications are wrong, which would be just as much of a reason not to use them!<br><br>Any claims about forward-secrecy they make is purely about their transport-layer encryption, which offers zero protection against corrupted servers. If someone corrupts signal’s servers they don’t get anything. If they corrupt Threema’s servers they get everything as ciphertexts that are merely encrypted with a pairwise static key that does not get updated.<br><br>A good messenger should not rely on the trustworthiness of the servers, so doing it like that does is not acceptable and enough reason to give the boot to their app.<br><br>As much as I dislike its lack of federation (not that Threema is doing any better there), this still means that </span><a href="https://blahaj.zone/tags/Signal" rel="nofollow noopener noreferrer" target="_blank">#Signal</a> remains my recommendation as messenger, with <a href="https://blahaj.zone/tags/matrix" rel="nofollow noopener noreferrer" target="_blank">#matrix</a><span> being an alternative that feels like it makes a degree of sense to me.
