Linus Gasser<p>We saw some supply-chain attacks on Linux distrubtions during <a href="https://social.epfl.ch/tags/insomnihack" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>insomnihack</span></a>. There an attacker would've been able to insert random code into packages. Now it seems to be the same for Fedora:</p><p><a href="https://fenrisk.com/pagure" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://</span><span class="">fenrisk.com/pagure</span><span class="invisible"></span></a></p><p>Which makes me wonder why they went through all that trouble with the XZ Utils backdoor (<a href="https://en.wikipedia.org/wiki/XZ_Utils_backdoor" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">en.wikipedia.org/wiki/XZ_Utils</span><span class="invisible">_backdoor</span></a>)? The frontdoor seems to be wide open!</p>

#insomnihack 2025 - keynote from Mathias Payer. I always like if a researcher presents a slide like this in 30 seconds by going over it "something, something, something" :)

But as always very interesting and eye-opening what kind of (non-)security we're relying on daily.
