TEEF**k’ed: CPUs From Intel, AMD, and NVIDIA Caught With Their Security Pants Down

Well, guess what, folks? The gods of silicon have done it again. Apparently, your shiny multi-thousand-dollar “secure” CPUs from Intel, AMD, and NVIDIA are about as leak-proof as a sieve in a hurricane. Some clever security researchers (read: people who actually know what the f**k they’re doing) cooked up a charmingly named tech-wreck called TEEfail. It basically takes a massive dump on “confidential computing” — that warm, fuzzy marketing bullshit that was supposed to keep your data safe inside fancy hardware enclaves.

Turns out, the geniuses at the big chip shops didn’t think attackers might, oh, re-purpose **CPU fault mechanics** to get secrets leaking faster than an intern with a USB stick. Using good old-fashioned hardware vulnerabilities, the researchers pulled sensitive data like cryptographic keys out of trusted execution environments (TEEs) — yeah, the supposedly impenetrable digital Fort Knox your cloud provider brags about in every f**king presentation. Spoiler: It’s not impenetrable. It’s barely a damp tissue.

Intel’s SGX? Screwed. AMD’s SEV? Buggered. NVIDIA’s H100 GPU? Toasted like last week’s patch notes. Each one has its own flavor of humiliation, from fault injection attacks to timing leaks, all beautifully unified under the TEEfail umbrella of “Oh shit, maybe don’t trust your processors after all.”

Vendors, of course, are acting *shocked and appalled*, promising “firmware updates” that’ll “mitigate” the issue — because, apparently, the fix for “broken by design” is to flash some new firmware and pray to the gods of marketing. Meanwhile, every sysadmin on earth is side-eyeing their servers wondering if half the company’s encryption keys are already on Pastebin.

So yeah, your data’s fine. Unless it’s not. Which it isn’t. But don’t worry — the vendors have your back. Just like a dentist pulling teeth with a car battery has your back.

Reminds me of the time some dimwitted user asked if their files were “safe on the cloud.” I told them yes — as long as they don’t mind every hacker in Eastern Europe getting a copy first. They laughed. I didn’t.
