New NetSpectre Attack Can Steal CPU Secrets via Network Connections

Scientists published a paper Friday detailing a new Spectre-class CPU attack that can be carried out via Network connections and does not require the attacker to host code on a targeted machine. From a report: This new attack --codenamed Netspectre -- is a major evolution for Spectre attacks, which until now have required the attacker to trick a victim into downloading and running malicious code on his machine, or at least accessing a website that runs malicious JavaScript in the user's browser. But with NetSpectre, an attacker can simply bombard a computer's network ports and achieve the same results. Although the attack is innovative, NetSpectre also has its downsides (or positive side, depending on what part of the academics/users barricade you are). The biggest is the attack's woefully slow exfiltration speed, which is 15 bits/hour for attacks carried out via a network connection and targeting data stored in the CPU's cache.
