Speculative Store Bypass (SSB) Attack
Speculative Store Bypass (SSB) attack is a security vulnerability that affects computer processors. When a processor executes instructions, it tries to predict what instructions will come next and loads them into its cache to speed up execution. This is called speculative execution.
A SSB attack exploits a flaw in speculative execution to access data that the attacker should not be able to see. Processes on the same computer can access each other’s data through a vulnerability known as a side-channel.
For example, an attacker can use a SSB attack to access the password stored in memory when a user logs in to a website. The attacker can use this information to gain unauthorized access to the user’s account.
To prevent SSB attacks, computer manufacturers and software developers have released security updates and patches. It is important to keep your computer and software up to date to stay protected against these types of attacks.
In summary, SSB attacks are a security vulnerability that exploit flaws in speculative execution to access sensitive data. It is important to stay informed about these types of attacks and take steps to protect your computer and data.
