Remote Access Tools Threatens Smartphones

Malware tools that allow attackers to gain complete remote control of smartphones have become a major threat to owners around the world, security researchers say.

In a demonstration at the RSA Conference 2012 here Wednesday, former McAfee executives George Kurtz and Dmitri Alperovitch, who recently founded security firm CrowdStrike, installed a remote access tool on an Android 2.2-powered smartphone by taking advantage of an unpatched flaw in WebKit, the default browser in the OS.

The researchers showed an overflow audience how the malware can be delivered on a smartphone via an innocuous looking SMS message and then be used to intercept and record phone conversations, capture video, steal text messages, track dialed numbers and pinpoint a user’s physical location.

The tools used in the attack were obtained from easily available underground sources, Kurtz said. The WebKit bug, for instance, was one of 20 tools purchased from hackers for a collective $1,400.

The remote access Trojan used in the attack was a modified version of Nickispy a well-known Chinese malware tool.

Learning how to exploit the WebKit vulnerability and to modify the Trojan for the attack, was harder than expected, said Kurtz. He estimated that CrowdStrike spent about $14,000 in all to develop the attack.

But the key issue is that similar attacks are possible against any smartphone, not just those running Android, he said.

WebKit for instance, is widely used as a default browser in other mobile operating systems including Apple’s iOS and the BlackBerry Tablet OS. WebKit is also is used in Apple’s Safari and Google’s Chrome browsers.

Several mobile remote access Trojans are already openly available from companies pitching them as tools that can be used to surreptitiously keep tabs on others.

80% Of Browsers Found To Be At Risk Of Attack

About eight out of every ten internet browsers run by consumers are vulnerable to attack by exploits of already-patched bugs, a security expert said today.

The poor state of browser patching stunned Wolfgang Kandek, CTO of security risk and compliance management provider Qualys, which presented data from the company’s free BrowserCheck service Wednesday at the RSA Conference in San Francisco.

“I really thought it would be lower,” said Kandek of the nearly 80% of browsers that lacked one or more patches.

BrowserCheck scans Windows, Mac and Linux machines for vulnerable browsers, as well as up to 18 browser plug-ins, including Adobe’s Flash and Reader, Oracle’s Java and Microsoft’s Silverlight and Windows Media Player.

When browsers and their plug-ins are tabulated together, between 90% and 65% of all consumer systems scanned with BrowserCheck since June 2010 reported at least one out-of-date component, depending on the month. In January 2011, about 80% of the machines were vulnerable.  Read more….
