You may be aware through the media, of two serious vulnerabilities named as Meltdown and Spectre.
Meltdown and Spectre exploit critical vulnerabilities in modern processors. These hardware vulnerabilities allow programs to steal data which is currently processed on a computer similar device. While programs are typically not permitted to read data from other programs, a malicious program can exploit Meltdown and Spectre to get hold of secrets stored in the memory of other running programs. This might include your passwords stored in a password manager or browser, your personal photos, emails, instant messages and even business-critical documents.
Meltdown and Spectre work on personal computers, mobile devices and in the cloud. Depending on the cloud provider's infrastructure, it might be possible to steal data from other customers. Although currently, no one has been affected, this could change at any time and due to the potential seriousness of these vulnerabilities we would recommend following the advice of your vendor or software provider regarding updates for your personal devices e.g. computers, laptops, notepads, tablets, mobile phones.
