Company security experts Apple once again warn users to be careful informs AppleInsider. The cause for concern was a seemingly harmless trick: an unknown hacker under the nickname “ikex” wrote a “worm” for iPhone, which changes the picture on the screen saver, of course, without the participation of the owner of the phone. At the whim of the enigmatic "ikex", your picture can change to an image of long-forgotten singer Rick Astley with the caption "ikee is never gonna give you up" (an allusion to Rick Astley's only hit, "Never Gonna Give You Up"). The worm was named - "Rickrolling".

A naive hacker still believes that people can change and become more reasonable and cautious, what will happen when the illusions are dispelled, what else can an angry computer scientist who decides to re-educate users come up with? Experts fear that from verbal warnings, the "craftsman" can move on to the point - to start using personal data (including banking), cracking passwords.
The virus threatens only those phones that use unlicensed applications. Either such phones are more vulnerable, or the hacker decided to wean phone owners in one fell swoop from piracy.
