Spectre and Meltdown attacks are two cyber threat vulnerabilities that can expose data in every computer device that requires a CPU (central processing unit) to function. Both cyber attacks can put every smartphone, computer, server and network at risk of losing all sensitive and important data held in its memory. A new Spectre attack variant has recently been discovered and is said to infect CPUs manufactured by tech giants Intel, AMD and ARM. There is still no known malware that exploits these flaws so chances of your data (e.g. credit card number) to be stolen is still pretty low.”]
