Data Exfiltration via Flow Hijacking at the Socket Layer

The severity of data exfiltration attacks is well known, and operators have begun deploying elaborate host and network security controls to counter this threat. Consequently, malicious actors spare no efforts finding methods to obfuscate their attacks within common network traffic. In this paper, we expose a new type of application transparent, kernel level data exfiltration attacks. By embedding data into application messages while they are held in socket buffers outside of applications, the attacks have the flexibility to hijack flows of multiple distinct applications at a time. Furthermore, we assess the practical implications of the attacks using a testbed emulating a typical data exfiltration scenario. We first prototype required attack functionalities with existing Layer 4.5 application message customization software, and then perform flow hijacking experiments with respect to six common application protocols. The results confirm the flexibility of socket layer attacks and their ability to evade typical security controls

Pauline Oliveros: A Shared Resonance

Here we honour Pauline Oliveros with an account of the resonances that she left with us. We reflect on how she organised sound and life, based on our shared experiences meeting her as a composer, performer, mentor, teacher and friend. The reader will meet us both as ‘I’, which we leave indistinguishable in order to follow and interweave the flow of our experience. Our resonance is also organised as if a Deep Listening score (in italics), with invitations to extend the experience through listening as meditation

The challenges of hydrogen and metals

The Royal Society Scientific Discussion Meeting ‘The challenges of hydrogen and metals’ was held in Carlton House Terrace, London, UK, on 16–18 January 2017. This is the introductory article to the discussion meeting issue which includes contributed papers and seven discussion papers. Here, we introduce the motivation to hold the Meeting and give a brief overview of the contents. We conclude with acknowledgements. This article is part of the themed issue ‘The challenges of hydrogen and metals’
