Mastodawn

In today's episode of "Can It Run Doom": DNS fucking TXT records.

Some absolute madlad (cough Adam Rice cough) compressed the entire shareware DOOM WAD, split it into around 1,964 chunks, shoved them into Cloudflare TXT records, and wrote a PowerShell script that reassembles and runs the whole goddamn game from DNS queries alone. Nothing touches disk. The DLLs are in DNS. THE FUCKING DLLS ARE IN DNS.

RFC 1035 was written in 1987. Those engineers are spinning in their graves fast enough to generate municipal power.

Bonus: this is a fully functional globally-distributed covert data exfil channel that your NGFW will never fucking see if you're not doing deep DNS inspection. Sleep well.

Also lmao @ every blue team that has never once looked at their DNS query volume. How's that DLP policy working out for you.

It was always DNS.

Sorry, I forgot about mastodon. I am trying to get back to being active here along with bluesky.

So in the last 10 months: Lost my job, got a job at Printed Solid as a manufacturing engineer. Moved to Maryland from Missouri. Sold the CNC to help pay for the move. Still laser cutting and 3D printing projects.

The Positron is just such a neat little printer.

It’s been quite a few months since I posted here.

I went to Open Sauce with my delta printer backpack. I also built the “cookiecad-astrophe” game for CookieCAD with a raspberry pi pico, CNC, pneumatics, and lots of printed parts.

I built a Positron V3.2 printer and brought it with me on my trip to Dallas for Quakecon. The Positron will be the next backpack printer I make for 3DPrintopia in Bel-Air, MD

I’ve been developing a parametric jewelry keepsake box that I can easily CNC and add a 3D printed insert to make attaching the hardware easier. I hope to include a simple tilt switch LED and mirror in the lid but it could be customized to a tiny lcd and raspberry pi if you really wanted to get fancy.

There are drill battery adapters for any major brand and also an assortment of power wheels drill battery adapters available. What a great way to reuse expensive proprietary battery systems.
