How Meltdown and Spectre Were Independently Discovered by Four Research Teams at Once

Great piece by Andy Greenberg for Wired:

Yet when Intel responded to the trio’s warning — after a long week of silence — the company gave them a surprising response. Though Intel was indeed working on a fix, the Graz team wasn’t the first to tell the chip giant about the vulnerability. In fact, two other research teams had beaten them to it. Counting another, related technique that would come to be known as Spectre, Intel told the researchers they were actually the fourth to report the new class of attack, all within a period of just months.

“As far as I can tell it’s a crazy coincidence,” says Paul Kocher, a well-known security researcher and one of the two people who independently reported the distinct but related Spectre attack to chipmakers. “The two threads have no commonality,” he adds. “There’s no reason someone couldn’t have found this years ago instead of today.”
