======Security - Vulnerabilities - Meltdown and Spectre======

[[https://spectreattack.com/|Meltdown and Spectre]] Vulnerabilities in modern computers leak passwords and sensitive data. "Meltdown and Spectre exploit critical vulnerabilities in modern processors. These hardware vulnerabilities allow programs to steal data which is currently processed on the computer."
