Title should be: ..in VIA C3 processors.

I am always wondering how those backdoors are discovered without internal leaks, fuzzing or enumerating all instructions bytes seem like too random.

Misleading, clickbait title. Technically accurate, but it would be accurate if it were 3 total cpu's rather than thousands or millions so that is a low bar.

Via C3 CPUs are the only ones affected. A security problem sure, but a relatively obscure one that doesn't effect anyone's laptop, server in the cloud, etc.

A reasonable title is "Backdoor found in Via C3 cpus".

A much better title would be "A hardware backdoor in a historical VIA x86 CPU".

While the README calls it a separate core, it's more likely to be a direct encoding of uops.

It’s lovely to think some x86 CPUs have a nice ISA buried under the layers of cruft that form a recent x86 ISA.

I still remember the time when mnemonics were 2 or 3 characters. Good days.

I recommend flagging this sort of crap to death...

Stupid autistic policy of "Don't editorialize the title"...

The backdoor(sic) is to delete and repost as you wipe the egg off your face.

The CPU is not the most used vector, the firmware is.

Can we add "some ancient Via CPUs" to the title. Current title is pure click bait.
