Microsoft spectre meltdown1/2/2024 Microsoft's speculative execution bounty program focuses has four tiers. "Speculative execution is truly a new class of vulnerabilities, and we expect that research is already underway exploring new attack methods," Phillip Misner, principal security group manager for Microsoft Security Response Center, says in a blog post. Many Intel processors, as well as some built by ARM, are vulnerable to variant 3, which is a rogue data cache load (CVE-2017-5754) known as Meltdown.Īlthough attacks exploiting the flaws are not necessarily simple, they could be used to recover passwords, encryption keys and other data in memory. Millions of processors built by Intel, AMD and ARM are vulnerable to variant 1 of these flaws, which is a bounds check bypass (CVE-2017-5753) known as Spectre, and variant 2, a branch target injection (CVE-2017-5715) also known as Spectre. But the functionality, which is physically built into processors, can be targeted via a trio of "side-channel attacks" to trigger information leaks. Speculative execution refers to a CPU optimization technique that's widely used in modern processors. Microsoft, following a similar move by Intel, has announced that until the end of this year, it will be offering bug bounties of up to $250,000 for information leading to the successful identification of speculative execution attacks (see Expect More Cybersecurity 'Meltdowns').
