Not true, the second variant of Spectre is harder to exploit on AMD, but possible. AMD is pushing microcode updates to close those holes, too.

- kllrnohj 9y agohttps://www.amd.com/en/corporate/speculative-execution https://www.amd.com/en/corporate/speculative-execution "Variant Two Branch Target Injection Differences in AMD architecture mean there is a near zero risk of exploitation of this variant. Vulnerability to Variant 2 has not been demonstrated on AMD processors to date." And although Project Zero had multiple AMD test machines they did not make any claims that AMD was also vulnerable to variant 2. Can you link to any PoC that has gotten variant 2 to work on AMD?
