NSA's Specialized Unit Intercepts Deliveries for Spyware Deployment

A special hacking unit of the U.S. National Security Agency intercepts deliveries of new computer equipment en route to plant spyware, according to a report on Sunday from Der Spiegel, a German publication.. The method, called "interdiction," is one of the most successful operations conducted by the NSA's Office of Tailored Access Operations (TAO), which specializes in infiltrating computers, wrote the publication, citing a top-secret document.

German Government Eavesdropping Tool Review On Security Failures

An eavesdropping tool allegedly used by the German government to intercept Skype calls is full of security problems and may violate a ruling by the country's constitutional court, according to a European hacker club.. The Chaos Computer Club obtained several versions of a program that has allegedly been used by German law enforcement in possibly hundreds of investigations to intercept Skype calls, said Frank Rieger, a member of the club.

Cisco 7900 DoS Risks: Interception and Security Concerns in VoIP

The VoIP 'revolution' has been talked of since the 1990's as the 'next big thing' in the enterprise telecoms sector; saving companies vast amounts of money on both call charges and internal network infrastructure and support costs. But just as the VoIP market is finally taking a cautious step towards delivering some of its long-overdue promise, the increasing priority of IT security may force it two steps back. . . .. During the past few years the two most significant focuses for remaining IT budget have been security and cost saving systems capable of demonstrating rapid ROI. But in almost all areas of business there is a trade off between risk and cost. As companies have double-locked the doors by spending on security for the data network, they may have left the windows open by pursuing saving in areas such as VoIP (Voice over Internet Protocol). The VoIP 'revolution' has been talked of since the 1990's as the 'next big thing' in the enterprise telecoms sector; saving companies vast amounts of money on both call charges and internal network infrastructure and support costs. But just as the VoIP market is finally taking a cautious step towards delivering some of its long-overdue promise, the increasing priority of IT security may force it two steps back. Recent research, by Secure Test, on the Cisco 7900 series VoIP phones have revealed serious security concerns (Note: Secure Test have independently tested the Cisco 7900 as this is the most widely used enterprise VoIP solution. Similar problems may well exist in other vendors products). With susceptibility to both DoS (denial of service) attacks and interception issues, it is clear that transferring phone systems to an IP network opens them up to many of the same security concerns as Ethernet data networks. More worryingly, phone systems may be harder or even impossible to patch. Like many IP devices Cisco's VoIP phones are vulnerable to ARP (Address Resolution Protocol) spoofing, allowing 'man-in-the-middle' attacks and including data interception and packetinjection. This means that any VoIP phone can be tapped by anyone else with a phone on the same network, any individual VoIP phone can be crashed easily and any VoIP network infrastructure is heavily vulnerable to DoS attacks. Looking first at the vulnerabilities of VoIP phones to DoS attacks, Secure Test's initial research has shown that Cisco 7900 series phones, specifically where running the default Skinny (SCCP) protocol for messaging, can be crashed relatively easily using one of several methods. By attaching a PC to the VoIP network it is possible to send malformed messages to a target phone or to cause a buffer overflow on one of several fields resulting in a crash. By performing any of these attacks on the switchboard phone, research demonstrated that it would be relatively trivial for an attacker to disable an entire phone system in minutes.

An increase in VoIP system security vulnerabilities is impacting enterprise IT budgets and risk management, necessitating investments in advanced security measures while managing costs.
