VoIP Ideal Platform For Controlling Botnets

Comments Off on VoIP Ideal Platform For Controlling Botnets

Botnets and their masters can communicate with one other by calling into the same VoIP conference call and exchanging data using touch tones, researchers demonstrated at Defcon.

This gives the botmasters — whose top goals include remaining anonymous — the ability to issue orders from random payphones and disposable cellular phones, say researchers Itzik Kotler and Iftach Ian Amit of security and risk-assessment firm Security Art.

Using phones and the public phone networks eliminates one of the prime tools bot fighters have: taking down the domains of botnets’ command and control servers, the researchers say. If the botmaster isn’t using a command and control server, it can’t be taken down.

In fact, the botmaster can communicate with the zombie machines that make up the botnet without using the Internet at all if the zombies are within a corporate network. So even if a victim company’s VoIP network is segregated from the data network, there is still a connection to the outside world.

In addition to its stealth, the VoIP tactic employs technology that readily pierces corporate firewalls and uses only traffic that is difficult for data loss prevention software to peer into. The traffic is streamed audio, so data loss prevention scanners can’t recognize patterns of data they are supposed to filter, the researchers say.

The downsides of VoIP as a command channel are that it severely limits the number of zombie machines that can be contacted at once, and the rate at which stolen data can be sent out of a corporate network is limited by the phone system. But Kotler and Amit say the connections are plenty big to send commands in.

During their demo at the conference, the pair had an Asterisk open source IP PBX stand in as the corporate PBX. A virtual machine representing a zombie computer on a corporate network called via TCP/IP through the PBX and into a corporate conference call. A BlackBerry, representing the botmaster dialed in over the public phone network to the same conference call.

Comments Off on Amex Debuts Mobile Payment System

American Express has just debuted a digital payment and commerce service that makes it possible to use Android-based devices and Apple iPhones for person-to-person online payments. Visa announced a similar personal payment product in the U.S. on March 16.

Comments Off on Is Motorola Building Its Own Mobile OS?

Motorola Mobility has snagged a number of experienced mobile and Web engineers from Apple and Adobe and is developing a Web-based mobile operating system as a potential alternative to Google’s Android software, according to a source familiar with the matter.

Asked to comment, Motorola did not refute the existence of the project but continues to affirm its interest in Android. “Motorola Mobility is committed to Android as an operating system,” a company spokesperson stated.

Jonathan Goldberg, an analyst with Deutsche Bank in San Francisco, said that he too had heard Motorola was at work on its own operating system. “I know they’re working on it,”  “I think the company recognizes that they need to differentiate and they need options, just in case. Nobody wants to rely on a single supplier.”
