HTTP2 Procotol Nears Completion
When it comes to amping up traffic over the Internet, sometimes too much of a good thing may not be such a good thing at all.
The Internet Engineering Task Force is putting the final touches on HTTP/2, the second version of the Hypertext Transport Protocol (HTTP). The working group has issued a last call draft, urging interested parties to voice concerns before it becomes a full Internet specification.
Not everyone is completely satisfied with the protocol however.
“There is a lot of good in this proposed standard, but I have some deep reservations about some bad and ugly aspects of the protocol,” wrote Greg Wilkins, lead developer of the open source Jetty server software, noting his concerns in a blog item posted Monday.
Others, however, praise HTTP/2 and say it is long overdue.
“A lot of our users are experimenting with the protocol,” said Owen Garrett, head of products for server software provider NGINX. “The feedback is that generally, they have seen big performance benefits.”
First created by Web originator Tim Berners-Lee and associates, HTTP quite literally powers today’s Web, providing the language for a browser to request a Web page from a server.
Version 2.0 of HTTP, based largely on the SPDY protocol developed by Google, promises to be a better fit for how people use the Web.
“The challenge with HTTP is that it is a fairly simple protocol, and it can be quite laborious to download all the resources required to render a Web page. SPDY addresses this issue,” Garrett said.
While the first generation of Web sites were largely simple and relatively small, static documents, the Web today is used as a platform for delivering applications and bandwidth intensive real-time multimedia content.
HTTP/2 speeds basic HTTP in a number of ways. HTTP/2 allows servers to send all the different elements of a requested Web page at once, eliminating the serial sets of messages that have to be sent back and forth under plain HTTP.
HTTP/2 also allows the server and the browser to compress HTTP, which cuts the amount of data that needs to be communicated between the two.
As a result, HTTP/2 “is really useful for organization with sophisticated Web sites, particularly when its users are distributed globally or using slower networks — mobile users for instance,” Garrett said.
HP Increases SlateBook Pricing
Hewlett-Packard’s SlateBook 14 laptop with Google’s Android OS has started shipping on schedule, but it’s priced at $429, which is $30 more than the company had said it would cost.
The laptop, which has a 14-inch screen and Android 4.3, was announced in June. At the time, HP said it would be priced at $399.
It is available on HP’s website.
The SlateBook 14 was introduced after customers told HP they wanted laptops with Android. The laptop has an interface similar to that on Android tablets and can adjust mobile apps to run on the larger touchscreen. Users will also be able to sync laptop data with mobile devices and vice versa.
The laptop is also for those who rely on the Web for most of their computing, much like Chromebooks. It has a few advantages over Chromebooks, with support for key Android apps such as Skype. Android also boasts better wireless printing support than Chromebooks.
The laptop weighs 1.68 kilograms and offers nine hours of battery life, according to specifications on HP’s website.
It has a quad-core Tegra 4 processor, 2GB of DRAM and 16GB of storage. Connectivity features include 802.11b/g/n Wi-Fi and Bluetooth 4.0. It also has a webcam, USB 3.0 port and a micro-SD slot for expandable storage.
It could be a strong multimedia laptop with a 1920 x 1080 pixel screen and an integrated graphics processor that can handle 4K video. TVs can be connected to the laptop through an HDMI port.

Comments Off on Can Lenovo Succeed With Tablets?
Lenovo on Friday said it would continue selling sub-10-in. Windows tablets in the U.S., backing away from statements it made the day before, when it said it was pulling the ThinkPad 8 from the North American market and had discontinued offering a model of the Miix 2.
“We will continue to bring new Windows devices to market across different screen sizes, including a new 8-inch tablet and 10-inch tablet coming this holiday,” Lenovo said in a press release published on its website Friday.
“Our model mix changes as per customer demand, and although we are no longer selling ThinkPad 8 in the U.S., and we have sold out of Miix 8-inch, we are not getting out of the small-screen Windows tablet business as was reported by the media (emphasis in original),” the statement continued.
On Thursday, the IDG News Service — like Computerworld, owned and operated by IDG – reported the withdrawal of the ThinkPad 8 and the 8-in. Miix from the U.S. market. The ThinkPad 8 had debuted in January at prices starting at $449, and the similarly-sized Miix had launched in October 2013.
Lenovo told IDG News that it was diverting remaining stocks of the ThinkPad 8 to other countries, including Brazil, China, and Japan, where demand was stronger for smaller Windows 8.1-powered tablets.
The China-based company, which has made impressive gains in the global market — it was the world’s largest personal computer seller during the second quarter, ahead of Hewlett-Packard and Dell, according to IDC — did not say exactly when it would return with an 8-in. device. If it begins selling the unnamed device in October, typical of OEMs that seed the channel then for the holiday sales season, it will have been absent from the market for two or more months.
Is China Spying?
Security experts claim that a Chinese manufacturer has been installing malware in its hand-held scanners that steals supply chain data.
TrapX says infected scanners made by an unnamed Chinese manufacturer located in Shandong province have been sold to eight unnamed firms including a large robotics company. The manufacturer denied knowledge that its scanners and website-hosted software were infected.
Sixteen of the 48 scanners deployed at one firm were infected, TrapX found. They all successfully sought out and compromised host names containing the word finance and siphoning off the logistical and financial data. The report Anatomy of the Attack: Zombie Zero said:
“Exfiltration of all financial data and ERP data was achieved, providing the attacker complete situational awareness and visibility into the logistic/shipping company’s worldwide operations,”.
TrapX suspected the attacks dubbed Zombie Zero were backed by the Chinese government and were a bid to gain intelligence on either logistics firms or their customers.

Comments Off on eBay Expands Mobile Shopping
Braintree, the payments gateway owned by eBay Inc, is working on removing a hurdle for e-commerce companies by making it easier for customers to directly pay for products on their smart phones.
The company rolled out a set of tools for software developers on Wednesday that allows businesses to deduct payments directly from a customer’s PayPal account.
The developer kit is the first big push from Braintree since it was bought by eBay for $800 million last year to help PayPal, eBay’s payments division, expand its presence on mobile devices.
Eliminating the need for mobile shoppers to type in their credit card details on their phones should help boost sales, Braintree Chief Executive Bill Ready said in an interview.
This is especially critical as consumers spend more time on their smartphones, a trend that is forcing developers to design a “fundamentally different computing experience” for the smaller screen, Ready added.
Braintree processes payments for businesses including car service Uber and online home-rental marketplace Airbnb.
Microsoft Adds Anti-snooping Safeguards

Comments Off on Microsoft Adds Anti-snooping Safeguards
Microsoft has added encryption safeguards to the Outlook.com webmail service and to the OneDrive cloud storage service, in part to better protect these consumer products from government surveillance.
“Our goal is to provide even greater protection for data across all the great Microsoft services you use and depend on every day. This effort also helps us reinforce that governments use appropriate legal processes, not technical brute force, if they want access to that data,” Matt Thomlinson, vice president, Trustworthy Computing Security, at Microsoft wrote in a blog post.
The move follows similar ones from other cloud computing providers. For example, Google announced end-to-end encryption for Gmail in April, including protection for email messages while they travel among Google data centers. It recently announced similar encryption for its Google Drive cloud storage service.
It’s not clear from Microsoft’s announcement whether the encryption protection it announced covers Outlook.com messages and OneDrive files as they travel within Microsoft data centers. It’s also not clear what, if any, encryption OneDrive and Outlook.com have had until now. Microsoft didn’t immediately respond to a request for comment.
Cloud computing providers like Microsoft, Google, Amazon and many others have been rattled by disclosures from former National Security Agency contractor Edward Snowden regarding government snooping into online communications, due to the effect on their consumer and business customers.
As a result, these companies have been busy boosting encryption on their systems, while also lobbying the U.S. government to stop the stealthy and widespread monitoring of Internet services.
Brits Investigate Facebook

Comments Off on Brits Investigate Facebook
The British data watchdog is looking into whether Facebook Inc violated data-protection laws when it gave permission to researchers to conduct a psychological experiment on its users.
A Facebook spokesman acknowledged that the experiment on nearly 700,000 unwitting users in 2012 had upset users and said the company would change the way it handled research in future.
The study, to find if Facebook could alter the emotional state of users and prompt them to post either more positive or negative content, has caused a furor on social media, including Facebook itself.
“We’re aware of this issue and will be speaking to Facebook, as well as liaising with the Irish data protection authority, to learn more about the circumstances,” the Information Commissioner’s Office (ICO) spokesman Greg Jones said in an email.
Jones said it was too early to tell exactly what part of the law Facebook may have infringed. The company’s European headquarters is in Ireland.
The Commissioner’s Office monitors how personal data is used and has the power to force organizations to change their policies and can levy fines of up to 500,000 pounds ($839,500).
Facebook said it would work with regulators and was changing the way it handled such cases.
“It’s clear that people were upset by this study and we take responsibility for it,” Facebook spokesman Matt Steinfeld said in an email.
“The study was done with appropriate protections for people’s information and we are happy to answer any questions regulators may have.”
Is Malware Wreaking Havoc On XP?
One of the top three malware programs affecting businesses in the second quarter is a worm that takes advantage of the large number of companies still using Windows XP, Trend Micro has warned.
The worm, dubbed DOWNAD, also known as Conficker, can infect an entire network via a malicious URL, spam email, or removable drive. Windows XP is particularly susceptible to this threat because it is known to exploit the MS08-067 Server service vulnerability in order to execute arbitrary code.
DOWNAD also has its own domain generation algorithm (DGA) that allows it to create randomly-generated URLs. It then connects to these created URLs to download files to the system. Trend Micro said that around 175 IP addresses are found to be related to the DOWNAD worm and that these IP addresses use various ports and are randomly generated via the DGA capability of DOWNAD.
“During our monitoring of the spam landscape, we observed that in Q2, more than 40 percent of malware related spam mails are delivered by machines infected by DOWNAD worm,” said Trend Micro anti-spam research engineer Maria Manly in a blog post.
“A number of machines are still infected by this threat and leveraged to send the spammed messages to further increase the number of infected systems. And with Microsoft ending the support for Windows XP this year, we can expect that systems with this OS can be infected by threats like DOWNAD.”
The security company warned that spam campaigns delivering FAREIT, MYTOB, and LOVGATE payloads in email attachments are attributed to DOWNAD infected machines. FAREIT is a malware family of information stealers that download variants of the Zeus Trojan, while MYTOB is an old family of worms known for sending a copy of itself in spam attachments.
The other top sources of spam with malware are the CUTWAIL botnet, together with Gameover ZeuS (GoZ). Manly said CUTWAIL was actually previously used to download GoZ malware but now a malware called UPATRE employs GoZ malware or variants of ZBOT which have peer-to-peer functionality.
“In the last few weeks we have reported various spam runs that abused Dropbox links to host malware like UPATRE,” Manly said. “We also spotted a spammed message in the guise of voice mail that contains a Cryptolocker variant. The latest we have seen is a spam campaign with links that leveraged CUBBY, a file storage service, this time carrying a banking malware detected as TSPY_BANKER.WSTA.”
According to Manly, cybercriminals and threat actors are probably abusing file storage platforms to mask their malicious activities and go undetected in the system and network.
“As spam with malware attachment continues to proliferate, so is spam with links carrying malicious files. The continuous abuse of file hosting services to spread malware appears to have become a favoured infection vector of cyber criminals most likely because this makes it more effective given that the URLs are legitimate thereby increasing the chance of bypassing anti-spam filters,” she added.
Salesforce Goes Healthcare
Salesforce Inc, one of the first cloud-computing companies, is turning its focus towards healthcare with new software and services aimed at the largest hospitals.
Salesforce has announced a strategic alliance with Amsterdam-based medical technology company Philips, which it envisions as the first of many partnerships. These companies will announce two new medical applications later in the summer, called Philips eCareCoordinator and Philips eCare Companion.
The software is designed to improve health and cut costs. The apps are intended to be used by physicians to monitor chronically ill patients between doctor visits.
Salesforce said the goal is to make it easier for hospitals to collect and analyze data from medical devices, which patients with chronic conditions often use at home.
“In the United States, care providers are facing increasing demands and decreasing reimbursement,” said Michael Peachey, a senior director of solutions and product marketing at Salesforce.
“We want to improve efficiency for physicians by transmitting patient data in real time.”
Peachey said the Salesforce software meets security and privacy rules under the Health Insurance Portability and Accountability Act, known as HIPAA.
In the short term, Peachey said Salesforce intends to develop additional apps with other partners to help doctors and nurses monitor patients from the comfort of their homes.
“It’s an open platform,” he said.
NSA Software Reengineered
Hackers have found a way to reverse engineer the technology of the United States National Security Agency (NSA) spy gadgets.
Thanks to documents leaked by fugitive former NSA contractor and whistleblower Edward Snowden, the group has built a copycat device able to gather private data from computer systems.
The Advanced Network Technology catalogue, leaked by Snowden, is the Argos book of the NSA showing a range of toys available to agents. One such device known has a “retro reflector” had eluded identification, beyond that it acted as a bug, keylogger and screengrabber.
Michael Ossman and his team from Great Scott Gadgets, a Colorado based hacking group, decided that the best defence against such devices was to create their own to understand what makes them tick.
It transpired that the key technology being used is called software defined radio (SDR), an approach that uses software to generate radio transmissions through signal processing, doing away with a lot of hardware circuitry.
“SDR lets you engineer a radio system of any type you like really quickly so you can research wireless security in any radio format,” Ossmann told New Scientist.
The technique can be used for almost any type of radio signal and therefore the devices are capable of tracking anything, from what you’re listening to through a Bluetooth headset to the binary signals of your internet traffic.
The group, which will demonstrate its work at the Defon hacking conference in Las Vegas, runs a website at NSAplayset.org that is a repository for all of the information it gathered.
