- Spectre is a security vulnerability that allows malicious actors to bypass system security protections present in nearly every recent device with a CPU, including IoT devices like routers and smart TVs1. Spectre attacks involve inducing a victim to speculatively perform operations that would not occur during correct program execution and which leak the victim’s confidential information via a side-channel to the adversary2. Spectre also works by tricking a processor to misuse speculative execution to read restricted values3.Learn more:✕This summary was generated using AI based on multiple online sources.
