SIP to SIP calls on a broadband internet connection are high quality, always free regardless of distance, and offer additional functionality such as free voicemail to email and phone numbers, caller ID, 3-way conference, speed dialing, call forwarding, simultaneous ring, call waiting, call return, caller ID block, and anonymous call rejection.

Reference. 2014: The Open Source Tipping Point. For the last ten years open source has expanded into more and more segments of the computing industry. But as we review 2014, a new story emerges: software development has fundamentally shifted toward an open source model. Especially for the infrastructure software used for scale-out computing, open source is the de facto choice; in fact it’s virtually impossible to find examples of scale-out infrastructure that are not open source. As Stephen O’Grady says in his excellent post on the Scale imperative: “Virtually any category of infrastructure software today – from the virtualization layer to the OS to the runtime to the database to the cloud middleware equivalents – has high quality, open source options available.” The economics of creating a new suite of infrastructure to power distributed computing required shared development and shared investment.

This version, sometimes referred to as iperf3, is a redesign of an original version developed at NLANR / DAST. iperf3 is a new implementation from scratch, with the goal of a smaller, simpler code base, and a library version of the functionality that can be used in other programs. iperf3 also incorporates a number of features found in other tools such as nuttcp and netperf, but were missing from the original iperf. Analysis of the Linux backdoor used in freenode IRC network compromise. Tuesday October 14, 2014 Background freenode is a large IRC network providing services to Free and Open Source Software communities, and in September the freenode staff team blogged about a potential compromise of an IRC server.

NCC Group’s Cyber Defence Operations team provided pro bono digital forensic and reverse engineering services to assist the freenode infrastructure team with their incident response activities. In this post we discuss a subset of the information we documented about one of the components involved in the compromise, specifically a Linux backdoor with some interesting functionality and features.
