CCC publishes 10 requirements for their evaluation from a technical and societal perspective. Currently, technically supported "contact tracing" is being considered as means to counteract the spread of SARS-CoV-2 in a more targeted manner. The general motivation is to allow greater freedom of movement for the broad spectrum of society by allowing quick tracing and interruption of infection chains. Contacts of infected persons should be alerted more quickly and thus be able to quarantine themselves more quickly. This, in turn, should prevent further infections. A "corona app" could therefore protect neither ourselves nor our contacts: It would be designed to break chains of infection by protecting the contacts of our contacts. ]]> covid-19 pandemics contact-tracing ccc privacy data-privacy https://pinboard.in/ https://pinboard.in/u:jm/b:4344f9c0f634/ 2017-03-24T09:50:49+00:00 https://medium.com/@odtorson/that-thing-about-pwning-n26-db3c9a7f8754#.dlkkzggbu jm ccc hacks exploits n26 banks banking security https://pinboard.in/ https://pinboard.in/u:jm/b:d733e5cdd80d/ 2016-01-04T12:38:40+00:00 http://www.theguardian.com/world/2015/dec/30/software-developers-helped-end-ebola-epidemic-sierra-leone?CMP=fb_us jmLittle known to the rest of the world, a team of open source software developers played a small but integral part in helping to stop the spread of Ebola in Sierra Leone, solving a payroll crisis that was hindering the fight against the disease. Emerson Tan from NetHope, a consortium of NGOs working in IT and development, told the tale at the Chaos Communications Congress in Hamburg, Germany. “These guys basically saved their country from complete collapse. I can’t overestimate how many lives they saved,” he said about his co-presenters, Salton Arthur Massally, Harold Valentine Mac-Saidu and Francis Banguara, who appeared over video link. ]]> open-source software coding payroll sierra-leone ebola ccc https://pinboard.in/ https://pinboard.in/u:jm/b:64890c343a1e/ 2013-12-30T21:30:43+00:00 http://www.bunniestudios.com/blog/?p=3554 jmToday at the Chaos Computer Congress (30C3), xobs and I disclosed a finding that some SD cards contain vulnerabilities that allow arbitrary code execution — on the memory card itself. On the dark side, code execution on the memory card enables a class of MITM (man-in-the-middle) attacks, where the card seems to be behaving one way, but in fact it does something else. On the light side, it also enables the possibility for hardware enthusiasts to gain access to a very cheap and ubiquitous source of microcontrollers. ]]> security memory hacking hardware ccc sd-cards memory-cards https://pinboard.in/ https://pinboard.in/u:jm/b:d66b01db4dc3/ 2012-01-09T22:27:43+00:00 http://shackspace.de/wiki/doku.php?id=project:hgg:faq jm space ccc satellite communication internet hackerspace https://pinboard.in/ https://pinboard.in/u:jm/b:56c795595368/ 2010-12-31T11:44:19+00:00 http://events.ccc.de/congress/2010/Fahrplan/events/4087.en.html jm ps3 hacks console crypto hypervisor security ccc fail0verflow https://pinboard.in/u:jm/b:4b6b9882cf48/
