BS.
They could do so only by causing a lot of single-bit flips
Why is this so hard to understand? ECC would detect the attack. It really is that simple, and that's a fundamental fact.
People who argue about undetectable 3-bit flips are incompetent and don't understand what they are talking about. They are either actively trying to be bad actors, or they have bought into the fairy tale from the bad actors.
And yes, in some theoretical universe you could have a single 3-bit flip without getting any single-bit flips. Anything can happen in theory. But that's like worrying about a meteorite targeting you personally. It's simply not a realistic worry, and it's not an argument against ECC.
Do you argue against airbags because they wouldn't save you from being killed in your car by a stray meteorite?
Can you really not see how stupid your argument is?
