I would not say "no one had thought about before". Side channel attack is not a novel idea, just not used to find Android bugs like this.

- ajross 1y ago> Side channel attack is not a novel idea Yes, but "side channel attack" isn't much of a description, is it? You can't just declare "I make a side channel attack!"[1], you need to invent one. In this case it turns out that the hardware rendering of the zoom animation in the blur effect of stacked activities on the screen left crumbs that can be detected in the alien context. I certainly didn't know that. Did you know that? I don't think anyone knew that! It's "novel". [1] Shades of Michael Scott declaring bankruptcy.
