A change meant to improve Google Chrome performance will also indirectly impact cryptojacking scripts (in-browser cryptocurrency miners) and will severely reduce their efficiency.
According to a design document seen by Bleeping Computer, Google engineers plan to limit the CPU power some types of JS scripts running in the browser’s background will be able to use.

Change is part of a bigger (unrelated) plan
Even if this change is part of a master plan to improve Chrome performance, Google engineers are particularly happy that this will impact cryptojackers as well.
“The goal of this intervention is to prevent scripts (particularly malicious ones) to adversely affect browsing performance and battery life for work users can’t see,” wrote Google engineers in the design document.
“This intervention also addresses the recent rise of malicious scripts performing power-heavy computations without user permission (e.g. cryptocurrency mining),” they also added.
Here are the current particularities of Google’s implementation plan:[….]
