A Look At Advanced Targeted Attacks Through the Lens of a Human-Rights NGO
An anonymous reader writes New research was released on cyber-attacks via human-rights NGO World Uyghur Congress over a period of four years. Academic analysis was conducted through the lens of a human-rights NGO representing a minority living in China and in exile when most targeted attack reports are against large organizations with apparent or actual financial or IP theft unlike WUC, and reported by commercial entities rather than academics. The attacks were a combination of sophisticated social engineering via email written primarily in the Uyghur language, in some cases through compromised WUC email accounts, and with advanced malware embedded in attached documents. Suspicious emails were sent to more than 700 different email addresses, including WUC leaders as well as journalists, politicians, academics and employees of other NGOs (including Amnesty International and Save Tibet — International Campaign for Tibet). The study will be presented at USENIX on August 21, and the full paper is already available. -
ISPs Throttling BitTorrent Traffic, Study Finds
hypnosec writes "A new report by an open source internet measurement platform, Measurement Lab, sheds light onto throttling of and restriction on BitTorrent traffic by ISPs (Internet Service Providers) across the globe. The report by Measurement Lab reveals that hundreds of ISPs across the globe are involved in the throttling of peer-to-peer traffic, and specifically BitTorrent traffic. The Glasnost application run by the platform helps in detecting whether ISPs shape traffic. Tests can be carried out to check whether the throttling or blocking is carried out 'on email, HTTP or SSH transfer, Flash video, and P2P apps including BitTorrent, eMule and Gnutella.' Going by country, United States has actually seen a drop in throttling compared to what it was back in 2010. Throttling in the U.S. is worst for Cox at 6 per cent and best for Comcast, Verizon, AT&T and others at around 3 per cent. The United Kingdom is seeing a rise in traffic shaping and BT is the worst at 65 per cent. Virgin Media throttles around 22 per cent of the traffic while the least is O2 at 2 per cent. More figures can be found here." -
Report on Web-Surfing Speeds Finds Pervasive Throttling
Stirling Newberry writes "New York Times has a report on web-surfing speed tests that their reporter ran using Glasnost, a tool that mimics the bittorrent protocol and measures the results. BT in the UK was among the worst. From the article: 'In the United States, throttling was detected in 23 percent of tests on telecom and cable-television broadband networks, less than the global average of 32 percent. The U.S. operators with higher levels of detected throttling included Insight Communications, a cable-television operator in New York, Kentucky, Indiana and Ohio, where throttling was detected in 38 percent of tests; and Clearwire Communications, where throttling was detected in 35 percent of the tests.'" -
Scientists Build Wireless Bicycle Brakes
itwbennett writes "Computer scientists at a German university have built a set of brakes controlled using a small motor for a braking mechanism and a wireless signaling device to tell it when to brake and how hard. 'Making a popular set of bike brakes wasn't really the point of the project,' says blogger Kevin Fogarty. 'The project was to find out how to make the wireless connections between two components of a system that has to operate in real time – with milliseconds of difference between success and failure (PDF) – more reliable than systems that are normally connected by a wire.'" -
On Social Networks, You Are Who You Know
santosh maharshi writes "On social networks like Facebook, even if you have kept your profile very private, people can just look at your friends list and infer lots of vital information about you. Most of the social networks like Facebook and LinkedIn allow people to see your picture and your friends list as part of the open access for visitors (the article says that only 5% of Facebook users have bothered to hide their friends list). In a study titled You Are Who You Know: Inferring User Profiles in Online Social Networks (PDF), conducted by Alan Mislove of Northeastern University and his colleagues at the Max Planck Institute for Software Systems, an algorithm was tested that can accurately infer the personal attributes of Facebook users simply by looking at their friend lists. 'At Rice [University], the algorithm accurately predicted the correct dormitory, graduation year, and area of study for the many of the students. In fact, among these undergraduates, researchers found that “with as little as 20 percent of the users providing attributes we can often infer the attributes for the remaining users with over 80 percent accuracy."'" -
Israeli ISPs Caught Interfering With P2P Traffic
Fuzzzy writes "For a long time, people have suspected that Israeli ISPs are blocking or delaying P2P traffic. However, no hard evidence was provided, and the ISPs denied any interference. Today Ynetnews published a report on comprehensive research that for the first time proves those suspicions. Using Glasnost and Switzerland, an Internet attorney / blogger found evidence of deep packet inspection and deliberate delays. From the article: 'Since 2007 Ynet has received complaints according to which Israeli ISPs block P2P traffic. Those were brought to the media and were dismissed by the ISPs. Our findings were that there is direct and deliberate interference in P2P traffic by at least two out of the three major ISPs and that this interference exists by both P2P caching and P2P blocking.'"
