‼️ Anthropic and Google researchers found a flaw that lets one crafted packet hijack a server during network boot, before Secure Boot checks the OS. Almost all servers on earth are affected. CVE-2026-97631 sits in TianoCore EDK II, code in the UEFI firmware of most servers.

Readers added context they thought people might want to know
The vulnerability is limited to servers actively PXE network-booting with vulnerable EDK II firmware; most servers boot from local disks and are unaffected in normal use, with Intel noting limited impact on supported products. github.com/tianocore/edk2… arstechnica.com/security/2026/…

I have written unnecessarily long article about my build of DIY Arrow antenna for sattelites 😂 melik.cz/posts/sattelites-bk…

Satellites, BKG and a bit of fun with Mr Yagi and Mr Uda

I’d sort of known that satellite operations existed. So far, however, I’ve spent most of my amateur radio time on shortwave. Time for new challenge.

You can do DATV-S2 stand alone (just power bank, no PC) beacon for your lab with smaller than stamp ESP32-C3 (6€). You dont need any programming tools, you can drop firmware and video with browser ! 📺📺Thanks to SP8ESA and TA7W/OH2UDS for software. github.com/barisdinc/ESP32-D…

After nearly a decade of grid chasing, grid # 2000 is confirmed! Every grid has a story behind it, and this milestone would not have been possible without the incredible satellite operators who helped along the way. Thank you all for making it happen! #amsat #hamradio
