Police arrest man in UK over US Defense Department network intrusion

British law enforcement agencies arrested a 23-year-old man suspected of being involved in a hacking attack last year against a satellite communications system operated by the U.S. Department of Defense.The network intrusion occurred on June 15 and resulted in data being stolen from Enhanced Mobile Satellite Services (EMSS), a system operated by the U.S. Defense Information Systems Agency (DISA) that provides U.S. troops and other DoD employees with global communication capabilities, including data transfers and voice calls.The stolen data included contact information for about 800 people, like names, titles, email addresses and phone numbers, as well as the identifying numbers (IMEIs) for 34,400 devices, the U.K. National Crime Agency (NCA) said Friday in a press release.To read this article in full or to leave a comment, please click here

Deprecating the DNS ANY meta-query type

DNS, one of the oldest technologies running the Internet, keeps evolving. There is a constant stream of new developments, from DNSSEC, through DNS-over-TLS, to a plentiful supply of fresh EDNS extensions.

New DNS Resource Records types are being added all the time. As the Internet evolves, new RR’s gain traction while the usage of some old record types decreases. Did you know you can use DNS to express the location of your server on the planet's surface?

Today, we are announcing that we are deprecating the DNS ANY meta-query. In a few weeks we'll be responding to those queries with rcode 4 / Not Implemented.

“ANY” is one of the special “magic” types in DNS. Instead of being a query for a single type like A , AAAA or MX, ANY retrieves all the available types for a given name. Over the years there have been many arguments over the semantics of ANY with some people arguing it really means ALL. Answers to ANY queries are among the biggest that DNS servers give out. The original reason for adding the ANY to DNS was to aid in debugging and testing Continue reading

Windows systems are also vulnerable to FREAK attacks

A cryptographic library used in all Windows versions is affected by a recently disclosed vulnerability in SSL/TLS implementations that allows man-in-the-middle attackers to force clients and servers to use weak encryption. Internet Explorer and other programs using the library are affected.The FREAK (Factoring Attack on RSA-EXPORT Keys) vulnerability stems from a decision made in the 1990s to limit the strength of RSA encryption keys to 512 bits in SSL (Secure Sockets Layer) implementations intended for export in order to meet U.S. government rules on exports of encryption systems.Those “export” cipher suites are no longer used today, but a team of researchers recently discovered that many servers still support them and some SSL/TLS clients, including Web browsers, can be forced to accept them because of bugs in the crypto libraries they rely on.To read this article in full or to leave a comment, please click here

Uber suspends ride-sharing platform in Seoul

Uber Technologies suspended its ride-sharing service in Seoul on Friday, bowing to local authorities after more than a year of struggle over its ride-hailing services.The decision comes only nine days after Uber made uberX free for riders there in response to a crackdown by city authorities, who offered a reward of up to 1 million won (US$910) to residents who reported drivers accepting payments for rides without a permit.“This is the strongest show of our willingness to change the Uber business model in order to create a regulated solution, as we believe that changing our business model is the right thing to do,” Uber said in a statement. The suspension takes effect Friday, it said.To read this article in full or to leave a comment, please click here

The Upload: Your tech news briefing for Friday, March 6

Bill targeting data brokers rises from the deadTheir last try failed to pass in 2014, but four U.S. senators have brought back legislation to rein in the data broker business. The law would allow consumers to see and correct personal information held by data brokers, and let them put a halt to having their information shared or sold for marketing purposes. The Data Broker Accountability and Transparency Act, introduced Thursday, is needed because data brokers are a “shadow industry of surreptitious data collection that has amassed covert dossiers on hundreds of millions of Americans,” Sen. Edward Markey said.To read this article in full or to leave a comment, please click here

Scalable Load Balancing with Avi Networks on Software Gone Wild

How many times have you received exact specifications of the traffic the e-commerce platform you have to deploy will generate? How do you buy a load balancer (application delivery controller in marketese) to support that (somewhat unknown) amount of traffic? In most cases, you buy a box that’s several times too big for the traffic the site is receiving most of the time, and still crashes under peak load.

SAP to cut 2,200 jobs, plans to recreate them in other parts of the company

SAP will cut over 2,200 jobs this year in activities where it sees no future, but plans to create others around cloud services and its HANA in-memory database offering, where it sees more potential.“There won’t be any impact on customers. We will ensure that we have sufficient hand-over time between colleagues who might be leaving and others taking over,” a company spokeswoman said Friday.The restructuring will affect about 3 percent of SAP’s 74,400 employees. Workers in Germany, France, the U.K. and the U.S. will be offered early retirement, or the opportunity to switch jobs and work for other divisions of the company. Staff in Europe won’t be forced to leave, but lay-offs can’t be avoided elsewhere, said the spokeswoman.To read this article in full or to leave a comment, please click here

Fujitsu tech can track heavily blurred people in security videos

Fujitsu has developed image-processing technology that can be used to track people in security camera footage, even when the images are heavily blurred to protect their privacy.Fujitsu Laboratories said its technology is the first of its kind that can detect people from low-resolution imagery in which faces are indistinguishable.Detecting the movements of people could be useful for retail design, reducing pedestrian congestion in crowded urban areas or improving evacuation routes for emergencies, it said.Fujitsu used computer-vision algorithms to analyze the imagery and identify the rough shapes, such as heads and torsos, that remain even if the image is heavily pixelated. The system can pick out multiple people in a frame, even if they overlap.To read this article in full or to leave a comment, please click here

Amazon opens store on Alibaba to sell imported goods in China

To reach more Chinese consumers, Amazon.com has opened an imported goods store on an Alibaba Group site.The new store will officially launch next month on Alibaba’s Tmall.com site, and will function as a pilot project, Amazon said Friday.Amazon already has its own e-commerce site geared for the country, but its share of China’s online retail market is only 0.8 percent, according to Beijing-based research firm Analysys International.Alibaba, in contrast, controls three quarters of the market through its Tmall and Taobao Marketplace sites, and has 265 million monthly active users.The Chinese market is fiercely competitive, as Amazon is not only competing against Alibaba, but also scores of other smaller e-commerce providers routinely offering promotional deals on products.To read this article in full or to leave a comment, please click here

ISIS supporters operated at least 46,000 Twitter accounts, study finds

Supporters of the Islamic extremist group known as ISIS operated at least 46,000 Twitter accounts at the end of last year, a new study says, underscoring the challenge facing social networks as they become powerful tools for propaganda and recruitment.The accounts were in use between September and December, and while not all were active at the same time, the estimate is a conservative one. The actual number could be as high as 70,000, according to the study, which was commissioned by Google Ideas and published by the Brookings Institution, a Washington, D.C., think tank.To read this article in full or to leave a comment, please click here
