Meltdown and Spectre exploit critical vulnerabilities in some of the main processor brands. These hardware vulnerabilities allow programs to steal data which is currently processed or in use on the computer. While programs are typically not permitted to read data from other programs, a malicious program can exploit Meltdown and Spectre to get information stored in the memory of other running programs. This might include your passwords stored in a password manager or browser, your personal data: photos, emails, instant messages and even business-critical documents.
Meltdown and Spectre work all kind of devices: on personal computers, mobile devices, and in the cloud.
