What is SpectrePatch?
This patch borrows heavily from Firefox’s methodology of mitigating Spectre after its recent outbreak.
It relies on reducing the resolution of Webkit’s performance.now() and disabling SharedArrayBuffer for blocking Spectre-based exploits.
For the uninitiated, Spectre is a critical security loophole present in microprocessors. There’s no patch for older devices and I highly recommend everyone to install any fix that developers release.
SpectrePatch is compatible only with iOS 9-10.3 versions.
The reason behind this is that performance.now() comes only with iOS 9 and above versions so devices with older versions are safe.
If you are on iOS 10.3.1 or above, the patch isn’t of much use as the necessary security measures are already in place. However, you can still give it a try should you so desire.
