![]() ![]() Hardware used by researchers from ETH Zurich to test Inception vulnerability attack (Courtesy: Kaveh Razavi/ ETH Zurich) Check If Your AMD CPU is Affected by Inception Attack You can read more about the Inception attack via the report available here (PDF). Since the mitigation process has begun anyway, Zen 3/ Zen 4 CPU users will be safe as long as they ensure to patch their systems with AMD’s upcoming AGESA Firmware update for the BIOS, or the µcode patch. AMD is not aware of any exploits out in the public utilizing ‘Inception’ vulnerabilities, apart from the research environment. The mitigation process is in the pipeline. Hence, users with Zen 3 and Zen 4 CPUs are recommended to update their systems timely and keep malware-detection tools active. By the way, this attack is similar to the ‘Spectre’ vulnerabilities found in Intel CPUs.ĭaniël Trujillo, a security researcher focusing on microarchitectures, said the following in relation to the Inception attack, “It looked as though we could make the CPUs manufactured by AMD believe that they had seen certain instructions before, whereas in reality that had never happened.”ĪMD’s report states that if newly downloaded malware could be utilizing these vulnerabilities, it can access sensitive and confidential data on your computer. This is true even though there are hardware & software mitigations in place, which remove harmful data within an information container such as a file, known as sanitization of the data. Researchers recently discovered that the mitigations implemented by AMD to prevent attackers from altering the state of microarchitectural buffers do not work effectively. The Inception vulnerability is described as a side-channel attack. ![]()
