The stories even followed a similar vein, "experts have been warning for years this could happen", etc, etc. "professor foobar confirmed that a bios implant could do this", "senior research blah built a pc speaker network to prove the theory", etc, etc.
BadBIOS was a single security researcher posting some dumps, which got repeated by clickbait lazy media with no confirmation. My point is: This Story Is Not That.
