"Screaming Channels" paper #CCS18/@BlackHatEvents is online s3.eurecom.fr/tools/screamin…
Electromagnetic side channels from a CPU can leak to a radio transmitter. CPU and radio transmitters are often integrated (think WiFi, BlueTooth)
We recover an AES key from 10 meters on a BT chip

New exploit: “xor dword [0xf80c2094], 1<<22”
Unlocks CPU microcode, the platform security processor, system management mode, and every internal processor register, all at once, on 100 million AMD CPUs. As far as I can tell can’t be fixed.

Amazing work by @henri2h and @aurelsec. Great to see SIMs and the SIM interface included in the attack surface. :)

Your x86 CPU has a hidden mode that no OS can touch, no hypervisor can see, and no security tool can monitor. The security community spent 20 years asking: what could go wrong? Turns out: a lot.

For 19 years, GPS satellites have secretly broadcast a “numbers station” in their public signals. We decoded 12M messages: a 2011 flash where 31 of 32 satellites flipped in hours, “ghost” substrings repeating years apart, and a “TEXT” prefix spreading now. lsc-pagepro.mydigitalpublica…

The RF world is insane.
Researchers recovered AES-128 keys from a Bluetooth chip by listening to its own antenna from 10 meters away.
Crypto-engine switching noise couples into the RF chain, rides the 2.4 GHz carrier, and leaks out as radio.
