CrowdStrike CEO George Kurtz will demonstrate a serious vulnerability in the WebKit mobile browser at the RSA conference tomorrow that could give malware complete control of your phone.
According to Kurtz, the new vulnerability affects all Android, iOS and newer BlackBerry devices. It does not affect devices running Microsoft Windows Phone 7. Kurtz said this means virtually every smartphone and tablet in use globally shares this vulnerability. Worse, security software currently available for mobile devices won't detect such malware and won't protect against it.
Kurtz is perhaps best known for his revelations regarding the Chinese Shady Rat operation that compromised US government and defense contractors in 2011. Kurtz discovered the Chinese cyber attacks on the US while he was CTO at McAfee. He left that company after the Intel acquisition.
Kurtz said that he compares the use of malware to the use of a gun. If someone is shooting at you, it makes more sense to take out the shooter rather than to stop the bullets, especially since the shooter can change the type of bullets he's using at any time. He said that users of malware can do the same thing and change the method of attack at any time.
Kurtz added that mobile devices are the next battlefield. "One of the things we talk about is the nation-state activity," Kurtz said. "We believe that this scenario is happening today. It's happening on mobile devices."
Kurtz said his company has been able to repurpose Chinese malware so it can take advantage of the Webkit vulnerability and take control of any mobile device. He said he's been able to control the camera and microphone on a mobile device, read email and text messages, and use the device to record what's happening around it. "It's the ultimate spy tool," he said.
Kurtz said the malware can be distributed by simply getting a user to click on a link that takes them to an infected website. Simply visiting the site would infect the device, and allow the remote operator of the malware to send data to a site anywhere in the world. "SMS messages could be a potential point of infection," Kurtz said.
For now, until the vulnerability is fixed, there's little anyone can do to prevent infection by the malware he describes, except to know not to click on links. In addition, he said it's important to make sure that software on mobile devices is kept updated, something that's not always possible on Android devices because of the fragmented update situation in the Android world.
Until security managers know that the mobile devices in their organisations have been updated, he said the best they can do is train users not to open links, and to be aware of what's installed on the devices. He also suggested disabling Android's ability to load applications from anywhere.
