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.
