Billions of devices potentially vulnerable to remotely executed NetSpectre attack

Originally published at:

Computer security researchers from the Graz University of Technology in Austria have developed a Spectre variant that makes it possible to steal data from network connected systems. The variant has been called NetSpectre and works without requiring the attacker to execute any code on the target system. When the attack is succesful, it’s possible for the attacker to obtain e.g. passwords or encryption keys. Billions of computers are potentially vulnerable.
