Cybersecurity in an Io T and Mobile World The technology world has spent so much of the past two decades focused on innovation that security has often been an afterthought. Read More Phillip Durachinsky, 28, a resident of North Royalton, Ohio, is accused in an indictment of building Fruitfly, a highly-invasive Perl-based malware that can allow the controller to secretly take complete control of an infected computer -- including recording from the webcam and microphone, viewing what's on the screen, controlling the keyboard and mouse, and remotely downloading files.

Durachinsky, who was 14 years old when he allegedly wrote the malware, used Fruitfly to infect thousands of computers -- including one government-owned machine -- to steal personal data, like tax and medical records, banking information, and passwords, according to an indictment filed Wednesday.

The FBI is said to have already opened an investigation into the malware, but the motives of the malware's author weren't immediately clear.

Wardle provided the FBI with technical insight into the malware amid the ongoing investigation. But Apple, according to Wardle, seemed equally focused on the prospect of negative media attention.

"Computers can so easily be turned into spying devices, and normally people don't worry too much -- they say, 'the Russians' or 'the NSA,' and think that they don't have anything to hide," he said."But it's really important [to know] that there are other, very perverse people out there who're trying to accomplish the same goal," he said.
