Spectre, also known as Spectre-BHB or branch history injection (BHI), is a software vulnerability that allows unauthorized access to sensitive data stored in the cache memory of computer systems. Discovered in 2018, it was initially dismissed by some in the semiconductor industry due to its potentially catastrophic implications. The vulnerability enabled side channel attacks such as timing attacks and power consumption monitoring attacks, which could exploit flaws in microprocessors to extract sensitive information. This vulnerability was not a cryptographic attack in the strict sense, but its demonstration highlighted the power of timing attacks. It broke all operating system security boundaries, affecting virtually every modern microprocessor, and led to a significant review of microprocessor architecture. The Spectre vulnerability was brought to Intel's attention in 2018 when the company was already dealing with other threats, notably Spectre and Meltdown. Despite this, the vulnerability re-emerged with the new hardware AmpereOne, indicating that past solutions were not entirely effective. Researchers have used this tactic to demonstrate how attackers can extract sensitive information from cache memory via microprocessor flaws like Spectre and Meltdown. The Spectre vulnerability, similar to previous ones like Meltdown, caused widespread concern due to its potential to expose confidential user data to hackers. In response to these vulnerabilities, various measures have been proposed and implemented to secure processors against such threats. The Caliptra specification was introduced to fend off cyberattacks and protect from vulnerabilities like Meltdown and Spectre. AMD issued an advisory recommending software developers follow their previously published guidance on how to protect against Spectre type attacks. Furthermore, MITRE rolled out four new common weakness enumerators (CWE) in February 2024 to describe and document different microprocessor weaknesses, aiding designers and stakeholders in better securing processors against vulnerabilities such as Spectre and Meltdown.
