New Malware Targets Apple Devices

FILE - A new 27-inch iMac computer is seen following a presentation at Apple headquarters in Cupertino, California, Oct. 16, 2014.

Palo Alto Networks Inc. has discovered a new family of malware that can infect Apple Inc.'s desktop and mobile operating systems, underscoring the increasing sophistication of attacks on iPhones and Mac computers.

The "WireLurker" malware can install third-party applications on regular iOS devices with unmodified operating systems and hop from infected Macs onto iPhones through USB connector cables, said Ryan Olson, intelligence director at Palo Alto Networks.

Palo Alto Networks said Wednesday that it had seen indications that the attackers were Chinese. The malware originated from a Chinese third-party app store and appeared to have mostly affected users within the country.

The malware spread through infected apps uploaded to the app store, which were in turn downloaded onto Mac computers. According to the company, more than 400 such infected apps had been downloaded over 350,000 times so far.

It's unclear what the objective of the attacks was. There is no evidence that the attackers had made off with anything more sensitive than messaging IDs and contacts from users' address books, Olson added.

But "they could just as easily take your Apple ID or do something else that's bad news," he said in an interview.

Apple, which Olson said was notified a couple weeks ago, did not respond to requests for comment Wednesday.

Once WireLurker gets on an iPhone, it can go on to infect existing apps on the device, somewhat akin to how a traditional virus infects computer software programs. Olson said it was the first time he had seen it in action.

"It's the first time we've seen anyone doing it in the wild," he added.
