Spectre and Meltdown vulnerabilities

By Martin Edwards

Updated 31 January 2018

It was announced at the start of the year that researchers have found serious weaknesses, which they have dubbed Spectre and Meltdown, in the design of modern computer processors.

These could be exploited by hackers to compromise people’s privacy or data. In a worst case, just visiting a website could give a third party access to everything on your device (though we are not aware of any such attacks being carried out yet).

The situation is unprecedented because it is so widespread: just about every current PC, Mac, smartphone and tablet is at risk. It will lead to changes in the way computers are designed in future, and only then will the problem be fully solved.

Right now, everyone should take steps to lessen the risk to them.

Key players in the industry have been working since last summer to prepare mitigations, many of which are now available. I will be developing this page, as my time permits and as information becomes available, to help my customers apply appropriate mitigations to protect themselves as best as possible.
