A friend found a tab open in Safari on their iPhone that they had not (knowingly) opened and whose history indicated it had visited a succession of locations, including multiple web searches and several different websites (some related to the web searches, some not). What are the likely ways that this could have occurred? Could this indicate a larger problem?

My best guess is that a site they opened had ads from some ad network with malvertizing on it that opened the extra tab and caused it to visit the various locations, but I'm really not sure.
