Meltdown and Spectre vulnerabilities – what to do?

/0 Comments/in , , , /by

Meltdown and Spectre are two vulnerabilities present in hardware making it potentially possible for programs to steal information, like passwords etc.

Meltdown affects only Intel processors while Spectre, which is more complex, also partly affects AMD and ARM based processors.

It is not yet known if these vulnerabilities has been exploited by anone. It can affect personal computers, servers, tablets and mobile phones, i.e. more or less any device containing a processor.

What can you do?

  • Check your operating system for updates the upcoming weeks (this is normal good security practice, but make sure you do it frequently)
  • Install and update your virus protection. Even if the antivirus program can’t protect you from the attack it might be able to inform you that your device has got malicious code onboard
