What is the industry term for a payment action that pops up over a free action?

The situation I mean is where a UI tries to hijack a user action by sneaking in another one on top.

For example, there might be screen with a button that does something innocuous, eg “Continue”, but about 1/2 a second after appearing (just enough time for your mouse/finger to be heading to the button to click it), a dialog box pops up whose action button, eg “Buy premium version”, is right over where the innocuous button was, attempting to capture/intercept the click you intended for the now-hidden button.
