World's first #CPU-level #ransomware can "bypass every freaking traditional technology we have out there" — new #firmware-based attacks could usher in new era of unavoidable ransomware
Beek, #Rapid7's senior director of threat analytics, revealed AMD Zen chip bug gave him idea that highly skilled attacker could in theory "allow those intruders to load unapproved #microcode into the processors, breaking encryption at the hardware level and modifying CPU behavior at will."

Extensive Analysis of the Raptor Lake CPU Bug

Intel’s Raptor Lake CPUs, which form part of the 13th and 14th generation Intel Core desktop processor line, were celebrated for their hybrid architecture combining high-performance cores with efficiency cores. However, shortly after their release, a critical bug emerged that has led to system instability and, in some cases, permanent degradation of the affected chips.

Yes. this is a good thing for #ITsec to let end-users know if their system runs #outdated / #vulnerable #Microcode and have #Linux update it.

  • OFC this can't fix the systemic issues #ix86 & #amd64 have, but I do think this is such a vital thing that I do want to integrate it into @OS1337 as having some low-level diagnostics and means to fix things is literally the point of said distro!

Consider it a more streamlined "Rescue Linux" which is intended to be #reprpduceable, #auditable and small enough to fit on a #BootROM!

Tom's Hardware · Intel engineer's Linux patch would alert users of outdated microcode — Flagging the system as vulnerableBy Hassam Nasir

Puntata dedicata a due temi per appassionati, la nuovissima distro linux che il Corriere della Sera definirebbe "tutta italiana" o "italianissima", noi ci limitiamo a essere un filo campanilisti comunque l'ottima Vanilla OS 2, e poi una questione devastante che riguarda le CPU desktop Intel e un problemino al microcode che le fa friggere.

Sì, anche spiegone sul microcode con disegnini.
