☢️ Before Stuxnet, fast16 was designed to corrupt nuclear weapons simulations.
The Lua-based sabotage malware tampered with uranium-compression modeling in LS-DYNA and AUTODYN, activating during 💥 detonation runs above 30 g/cm³.
The framework may date back to 2005.

Bonus: EMET 5.52 (the final EMET version) doesn't appear to detect this (on Windows x64 it seems)

EPIC JAILBREAK: Introducing checkm8 (read "checkmate"), a permanent unpatchable bootrom exploit for hundreds of millions of iOS devices.
Most generations of iPhones and iPads are vulnerable: from iPhone 4S (A5 chip) to iPhone 8 and iPhone X (A11 chip).

Bluetooth negotiates keylength in the clear before key exchange starts; either party can force the length to 8 bits, and so can a middleman. How on earth did this get agreed by dozens of tech companies, and get past NIST?
Bluetooth is broken: A third party can force a one byte encryption key on any Bluetooth connection in range, even between already paired devices. It's bad. knobattack.com/
