NYT: "U.S. Escalates Online Attacks on Russia’s Power Grid"
by J.C. DE MARTIN June 17, 2019

June 17, 2019

*U.S. Escalates Online Attacks on Russia’s Power Grid** * By David E. Sanger and Nicole Perlroth June 15, 2019 WASHINGTON — The United States is stepping up digital incursions into Russia’s electric power grid in a warning to President Vladimir V. Putin and a demonstration of how the Trump administration is using new authorities to deploy cybertools more aggressively, current and former government officials said. In interviews over the past three months, the officials described the previously unreported deployment of American computer code inside Russia’s grid and other targets as a classified companion to more publicly discussed action directed at Moscow’s disinformation and hacking units around the 2018 midterm elections.

The purpose of this project is to question the economic structure of Airbnb and to unveil hidden phenomena as dynamics in the ongoing polarization of society, and therefore *interpreting Airbnb as an indicator of social discomfort and precariousness rather than of innovation*. Assuming this statement, the discourse regarding platform urbanism could be implemented and considered an additional tool to investigate inequalities in cities, giving relevance to place-based information and what it can possibly imply in a human geographical perspective. The paper focuses on post-crisis cities, in particular on a set of major Southern European ones (Athens, Thessaloniki, Palermo, Naples, Lisbon, Porto, Seville, Madrid) so as *to trace and visualize specific socio-spatial effects of the economic crisis *through the analysis of platform urbanization. The results will be shown with the aim of collecting cases and comparing them, to obtain a broader frame to analyze the phenomenon. /Ingresso libero - Sarà disponibile un leggero rinfresco per coloro che si saranno registrati su http://lunch70.eventbrite.com entro il 24 giugno./ BIOGRAFIE - e informazioni supplementari [Iacovone] *Chiara IACOVONE* is a PhD candidate in Urban and Regional Development at Polytechnic of Turin and member of the interdepartmental center Future Urban Legacy Lab <https://full.polito.it/>.

Joseph Choonara reviews Zuboff "The Age of Surveillance Capitalism"
by J.C. DE MARTIN June 15, 2019

June 15, 2019

/"There is much to admire in Zuboff’s work, particularly the mass of evidence she assembles. However, her single-minded obsession leads to a common pitfall in literature of this kind. It is one thing to identify a central feature of contemporary capitalism, quite another to announce a new paradigm — the “new economic order” of surveillance capitalism — that shades all other aspects of the system.// // //Such an approach involves minimising criticisms of earlier phases of capitalism and downplaying the extent to which the tech giants are simply outgrowths of capitalist logic."// / jc *The logic of capital online** * June 2019 (447) By Joseph Choonara *Shoshana Zuboff’s new book, The Age of Surveillance Capitalism, explores the world of the giant tech companies such as Google, Microsoft, Apple and Amazon. We all know they collect our data for profitable uses; how deeply does this affect capitalist relations, asks Joseph Choonara.* ** I was part of the last generation in Britain to experience childhood before the Internet. It still seemed miraculous when, in the mid-1990s, it became possible to browse the Web, using search engines such as Altavista and Lycos — Google being as yet neither a search engine nor a verb. The Internet had none of the pervasiveness it has today. Mobile phones, for those who had them, were mostly used for phone calls. Beyond my university computer room, going online meant using a dial-up modem with speeds one thousandth of my current connection.

[Equiliber] Potersi fidare dei client con Intel SGX
by Stefano Quintarelli June 14, 2019

June 14, 2019

segnalo PAPER1: https://www.ibr.cs.tu-bs.de/users/goltzsch/papers/eurosec2017-trustjs.pdf Client-side JavaScript has become ubiquitous in web applicationsto improve user experience and reduce server load. However, sinceclients are untrusted, servers cannot rely on the confidentiality orintegrity of client-side JavaScript code and the data that it operateson. For example, client-side input validation must be repeated atserver side, and confidential business logic cannot be offloaded. Inthis paper, we presentTRUSTJS, a framework that enables trust-worthy execution of security-sensitive JavaScript inside commoditybrowsers.TRUSTJSleverages trusted hardware support providedby Intel SGX to protect the client-side execution of JavaScript, en-abling a flexible partitioning of web application code. We presentthe design ofTRUSTJSand provide initial evaluation results, show-ing that trustworthy JavaScript offloading can further improve userexperience and conserve more server resources. PAPER2: https://www.ibr.cs.tu-bs.de/users/goltzsch/papers/dsn18-endbox.pdf Many organisations enhance the performance, secu-rity, and functionality of their managed networks by deployingmiddleboxescentrally as part of their core network. While thissimplifies maintenance, it also increases cost because middleboxhardware must scale with the number of clients. A promisingalternative is to outsource middlebox functions to the clientsthemselves, thus leveraging their CPU resources. Such an ap-proach, however, raises security challenges for critical middleboxfunctions such as firewalls and intrusion detection systems.We describe ENDBOX, a system that securely executes mid-dlebox functions on client machines at the network edge. Itsdesign combines a virtual private network (VPN) with middleboxfunctions that are hardware-protected by a trusted executionenvironment (TEE), as offered by Intel’s Software Guard Exten-sions (SGX). By maintaining VPN connection endpoints insideSGX enclaves, ENDBOXensures that all client traffic, includingencrypted communication, is processed by the middlebox. Despiteits decentralised model, ENDBOX’s middlebox functions remainmaintainable: they are centrally controlled and can be updatedefficiently. We demonstrate ENDBOXwith two scenarios involving(i) a large company; and (ii) an Internet service provider thatboth need to protect their network and connected clients. Weevaluate ENDBOXby comparing it to centralised deployments ofcommon middlebox functions, such as load balancing, intrusiondetection, firewalling, and DDoS prevention. We show thatENDBOXachieves up to3.8×higher throughput and scaleslinearly with the number of clients. -- Marco "Now produce your explanation, and pray make it improbable!" _______________________________________________ Equiliber mailing list Equiliber(a)server-nexa.polito.it https://server-nexa.polito.it/cgi-bin/mailman/listinfo/equiliber
