Yesterday, police in Arizona reported an extraordinary number of phone calls - about 100 in a few minutes. As it turned out, they were caused by a file written in JavaScript, and the file has been shared by a teenager from Arizona on Twitter. The purpose of this file was to force the iPhone to make calls to the number 911 19 times. A teenager has already been captured, and files instantly disappeared from Twitter. The whole history shows that it is worthwhile to pay attention to links which we open.
