Recently I’ve noticed that, every so often, my iPhone spontaneously opens the app store page for some stupid game or other. It’s usually when I’m reading a blog with advertising on it, or looking at pictures of kittens. Sometimes it happens from Safari, and sometimes from apps serving their own content. It seems that I’m not aloneinfinding this annoying, and it looks like it may affect Android devices too. Worried (as others are) that this might be some novel strain of malware, I decided to do a bit of digging, which revealed that one of the embedded advertising networks is being an arsehole.
