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.

More information on: https://spectreattack.com/

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

You can find security bulletins, security advisorys, faq:s etc for your operating system here: https://meltdownattack.com/#faq-advisory

Smooth scrolling not working for my website on IOS devices like iphone and ipad

/0 Comments/in /by

On iPhone and iPad, i.e. IOS devices, in some cases the smooth, accelerated scrolling is not working. Instead the web page feels “lagging”, slow or stuttering and won’t continue to scroll in the smooth accelerated way you are used to.

To solve this, make sure to use overflow-y: scroll; (not auto) and apply  -webkit-overflow-scrolling: touch; to body and possibly other elements. If it is not enough to apply it to the body you might need to also apply it to your div:s, like the wrapper div and so on.

body {
overflow-y: scroll;
-webkit-overflow-scrolling: touch;
}
