Kocher and colleagues: Spectre speculative-execution attacks

What changed

A broad class of processor security assumptions was experimentally falsified.

Scientific scope

Exact 2019 paper and demonstrated attacks; Meltdown, later variants and mitigations separate.

Evidence

The linked sources identify this contribution and its scope. WRS has not independently reconstructed the scientific claims. The record is the exact 2019 IEEE paper and its twelve-author final byline. Meltdown, later Spectre variants, vendor mitigations, disclosure coordination and every affected processor remain separate.
