      It&#x27;s just as good in 2026 - 2d. Imagine Santa delivering his goods and hearing a mysterious UDP stream and wondering, &quot;Is my supply chain being disrupted?&quot;, only to then realize that it was just the owners&#x27; TV spying on him after it was left on standby instead being completely turned off.

    This is the kind of curiosity that leads to the most interesting findings. Hotels are a perfect storm of shared networks, opaque vendor integrations, and “it just works” assumptions. A mysterious UDP stream could be anything from Chromecast-style discovery to IPTV control or some half-documented vendor heartbeat. What’s usually more revealing than the payload is the pattern: broadcast vs unicast, frequency, and who responds. Also a good reminder of how much ambient network noise we’re all swimming in without noticing.

      Thank you for writing one of my favorite blog posts of all time! I am curious: What is <i>your</i> favorite thing you’ve written?

      Hi! Do you happen to have that elevator music saved? I&#x27;m curious what it sounded like.
      • gkbrk6 hours ago
        I had it saved, but it was 3-4 computers ago. I don&#x27;t think I still have it, and if I did I wouldn&#x27;t know where.<p>Aside from the article, I only found these scripts on my disk related to this project.<p>listen_2046.py and send_2046.py<p><a href="https:&#x2F;&#x2F;gist.github.com&#x2F;gkbrk&#x2F;445929a854051203ee31afc7495c5a87" rel="nofollow">https:&#x2F;&#x2F;gist.github.com&#x2F;gkbrk&#x2F;445929a854051203ee31afc7495c5a...</a>

      Since you appear to be Turkish what&#x27;s your favourite Turkish food that is poorly known outside of the country? Also don&#x27;t miss <a href="https:&#x2F;&#x2F;subseacables.blogspot.com&#x2F;2025&#x2F;12&#x2F;fully-diverse-100g-waves-sofiaistanbul.html" rel="nofollow">https:&#x2F;&#x2F;subseacables.blogspot.com&#x2F;2025&#x2F;12&#x2F;fully-diverse-100g...</a>

        &quot;poorly known outside the country&quot; rules out the main foods I like.<p>I love a good Kuymak [1] though, I think that&#x27;s not too well known.<p>[1]: <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Kuymak" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Kuymak</a>

          Nice, haven&#x27;t tried that. Found a local cafe which looks very well run where it&#x27;s a feature. On the list for next year! Happy New Year!

    This is the shortest, yet still fully complete example of an article that scratches <i>that</i> itch. Awakening the &quot;intellectual curiosity&quot;, documenting the steps, and finding the actual end of the matter. The mundanity of the revelation is like the icing on the cake.

    I LOLed at the ending. Nicely done!<p>I appreciate people posting negative results, too. The journey is the interesting part, and I like the humanity of saying &quot;welp, at least now I know&quot;.
    • mingus887 hours ago
      Yeah 99&#x2F;100 times it’s gotta be mundane but wouldn’t it be interesting to spoof that traffic and play anything you wanted in the elevator?
      • kstrauser7 hours ago
        &quot;That would be wrong. You totally should not do that.&quot;<p>But yes, absolutely!

    Good hotel room hacking entertainment is provided in-house, in this case.

    I&#x27;ve read this one before, but this time it really hit home in how unlike most of the modern AI-emoji-filled-cringy-heading-20-page blog slop, it is. Very refreshing.

    I was expecting to see a post bemoaning the lack of encryption on the elevator music...
