I think a simple keylogger that also reads window titles is much easier to build, than to read and control content inside a browser. This kind of technique would work really well if they are targeting a small group of users. One can argue that reading browser content through a browser extension would be equally easy to implement, but that's harder to hide and limits your scope to only browser activity.
