SpectrePatch is a patch for javascript-based Spectre exploits that might infect Apple devices. It is developed by tweak developer, Ryley Angus.

It relies on reducing the resolution of Webkit’s performance.now() and disabling SharedArrayBuffer for blocking Spectre-based exploits.

It injects its code into every WebKitContent process and other apps such as web browsers like Safari, Chrome or Firefox. Remember, it can only block javascript-based exploits, not native exploits.

For the uninitiated, Spectre is a critical security loophole present in microprocessors. There’s no patch for older devices and we highly recommend everyone to install any fix that developers release.

SpectrePatch is compatible only with iOS 9-10.3 versions.
