3G And 4G Modems Pose Security Threats
Researchers Nikita Tarakanov and Oleg Kupreev analyzed the security of 3G/4G USB modems obtained from Russian operators for the past several months. Their findings were presented Thursday at the Black Hat Europe 2013 security conference in Amsterdam.
Most 3G/4G modems used in Russia, Europe, and probably elsewhere in the world, are made by Chinese hardware manufacturers Huawei and ZTE, and are branded with the mobile operators’ logos and trademarks, Tarakanov said. Because of this, even if the research was done primarily on Huawei modems from Russian operators, the results should be relevant in other parts of the world as well, he said.
Tarakanov said that they weren’t able to test baseband attacks against the Qualcomm chips found inside the modems because it’s illegal in Russia to operate your own GSM base station if you’re not an intelligence agency or a telecom operator. “We’ll probably have to move to another country for a few months to do it,” he said.
There’s still a lot to investigate in terms of the hardware’s security. For example, the SoC (system on a chip) used in many modems has Bluetooth capability that is disabled from the firmware, but it might be possible to enable it, the researcher said.
For now, the researchers tested the software preloaded on the modems and found multiple ways to attack it or to use it in attacks.
For one, it’s easy to make an image of the USB modem’s file system, modify it and write it on the modem again. There’s a tool available from Huawei to do modem backup and restore, but there are also free tools that support modems from other manufacturers, Tarakanov said.
Malware running on the computer could detect the model and version of the active 3G modem and could write an image with malicious customizations to it using such tools. That modem would then compromise any computer it’s used on.
The researchers also found a possible mass attack vector. Once installed on a computer, the modem application — at least the one from Huawei — checks periodically for updates from a single server, Tarakanov said. Software branded for a specific operator searchers for updates in a server directory specific to that operator.
An attacker who manages to compromise this update server, can launch mass attacks against users from many operators, Tarakanov said. Huawei 3G modems from several different Russian operators used the same server, but there might be other update servers for other countries, he said.
Research in this area is just at the beginning and there’s more to investigate, Tarakanov said. Someone has to do it because many new laptops come with 3G/4G modems directly built in and people should know if they’re a security threat.
HP Goes All-In On Tablets
Hewlett-Packard garnered attention at Mobile World Congress show with its new Slate 7-inch tablet and then the sale of webOS assets, but the company is looking to put past distractions behind and will release more tablets in the future, the company said.
“You can expect going forward [to release] a family of products,” said Shane Wall, chief technology officer at Hewlett-Packard’s mobility group, in an interview at MWC. The mobility trade show is being held in Barcelona from Feb. 25 to 28.
The 7-inch tablet attracted a small crowd at the HP booth, with people lining up to photograph or use the device. The company effectively took a dive into the low-cost tablet and tried to differentiate its tablet by a lower price, and also features like a micro-SD card slot for expandable storage and dual-cameras. Google’s $199 Nexus 7 is priced higher and has a quad-core processor, a higher-resolution screen and Android 4.2, but HP believes it will sell a lot of the tablets at the $169 price.
“We’re obviously late,” Wall said. “We wanted to start and see how aggressive we can be on the low end.”
The Slate 7 also signifies HP’s re-entry into the consumer tablet market after a disastrous stint with the webOS mobile operating system, which it got with the acquisition of Palm in 2010 for $1.2 billion. The first webOS tablet, the TouchPad, was launched in 2011, but later discontinued along with webOS smartphones. Since then HP has released enterprise tablets such as ElitePad 900 with Windows 8, and now the company has adopted Android for consumer tablets.
Is Non-Volatile Memory The Next Craze?
A report from analysts Yole Developpement claims that MRAM/STTMRAM and PCM will lead the Emerging Non-Volatile Memory (ENVM) market and earn a combined $1.6bn by 2018. If the North Koreans have not conquered America, by 2018 then MRAM/STTMRAM and PCM will surely be the top two ENVM on the market.
Yole’s Yann de Charentenay said that their combined sales will almost double each year, with double-density chips launched every two years. So far we have only had FRAM, PCM and MRAM to play with and they were available in low-density chips to only a few players. The market was quite limited and considerably smaller than the DRAM and flash markets which had combined revenues of $50bn+ in 2012, the report said. In the next five years the scalability and chip density of those memories will be greatly improved and will spark many new applications, says the report.
ENVM will greatly improve the input/output performance of enterprise storage systems whose requirements will intensify with the growing need for web-based data supported by cloud servers, the report said. Mobile phones will increase its adoption of PCM as a substitute to flash NOR memory in MCP packages thanks to 1GB chips made available by Micron in 2012, it added. The next milestone will be the higher-density chips, expected in 2015, will allow access to smart phone applications that are quickly replacing entry-level phones.
Intel Wins Patent Case
Intel has had a previous decision upheld by the US International Trade Commission (ITC), which decided it did not infringe several X2Y chip manufacturing patents.
X2Y had claimed that Intel’s chip manufacturing technology infringed five of its patents and requested an injunction to stop the chips from entering the US. Previously Judge David Shaw ruled that Intel did not infringe X2Y’s patents, a decision that has been upheld by the ITC, which said it will “terminate the investigation with a finding of no violation”.
X2Y’s patents relate to the shielding of electromagnetic interference that is a significant problem in electronics manufacture. The firm has sold licenses to other chipmakers including Samsung, however Intel decided to develop its own techniques, which are now deemed not to infringe X2Y’s patents.

While Intel had the most to lose, X2Y also went after Apple and HP, two of Intel’s highest profile customers. Intel even argued that an injunction on its chips would hurt American jobs.
Not only did X2Y lose its patent battle with Intel, but two of its patents were ruled invalid. The company had filed two civil lawsuits that were put on hold pending the ITC’s decision, but given the ITC action it will be surprising if the firm continues in its legal campaign against Intel.
MS Surface Pro Sells Out
Microsoft started selling its Surface Pro tablet last Saturday, and quickly ran out of its supply of the 128GB configuration.
While the less expensive 64GB device was also listed as out of stock Saturday on Microsoft’s online store, by Sunday it was again available.
The company acknowledged the outages.
“We’re working with our retail partners who are currently out of stock of the 128GB Surface Pro to replenish supplies as quickly as possible,” said Panos Panay, general manager for Microsoft’s Surface line, in a Saturday blog post. “Our priority is to ensure that every customer gets their new Surface Pro as soon as possible.”
Numerous online reports noted the shortages, saying that some Microsoft retail stores sported Apple-esque lines on Saturday and that many Best Buy and Staples locations — Microsoft’s retail partners for the Surface in the U.S. — had single-digit supplies that in some cases were claimed earlier in the week.
Microsoft is selling the Surface Pro in the U.S. through its online e-mart, its approximately 70 retail outlets, and the Best Buy and Staples chains.
The device, which runs Windows 8 and is powered by an Intel processor, sells for $899 in a 64GB storage configuration, and for $999 with 128GB. Keyboard-cover accessories — the Touch Cover and Type Cover — sell separately for $120 and $130, respectively.
Samsung Goes Star-ups
Samsung will put $1.1 billion towards venture capital funding of semiconductor firms.
The company said that it will commit the research and development funding through its Samsung Venture Americas branch and Catalyst Fund investment operations, according to multiple reports.
The investment is set to target semiconductor design and manufacturing. The company will look to fund startups that can assist its hardware units and will open a new R&D facility in Silicon Valley.
The announcement comes as Samsung is seeing its revenues hit record levels. The company reported quarterly profits of 7.5 billion to close out 2012 and sales from Samsung’s handset unit reached record levels.
Analysts believe that the company now controls nearly 23 percent of the smartphone market. The jump in hardware sales has brought with it a healthy appetite for components. Earlier this month Samsung passed Apple to become the world’s largest single user of semiconductor chips.
Samsung has recently stepped up its investment activities, with the firm buying storage vendor Nvelo and last week buying a small stake in Wacom, best known for its touchpad and stylus input technology. With the firm looking to invest in startups, it is perhaps looking to follow in Apple’s footsteps, which kickstarted its chip design efforts by buying PA Semiconductor and later Intrinsity, and invested in Imagination Technologies.
HP Looks Beyond Windows
Hewlett-Packard has announced the availability of its latest Pavilion laptop with Google’s Chrome OS as the PC maker attempts to improve laptop sales by offering an alternative to the Windows OS.
The Pavilion 14 Chromebook has a 14-inch screen and runs on a dual-core Intel processor. The laptop is roughly 21 millimeters thick, and weighs 1.8 kilograms. It offers just over four hours of battery life, said David Conrad, director for product management at HP’s consumer products group.
The laptop is expected to ship on Monday in the U.S. starting at $329.99. The company did not immediately provide worldwide availability information.
HP wanted to widen its product offerings and the new Chromebook is targeted at those who do most of their computing on the Web, Conrad said.
“It’s really about choice. We have a very wide offering,” Conrad said. “We think the time is right for an additional choice for people to have a gateway to their Google digital lifestyle.”
The laptop has only 16GB of solid-state drive storage, but will offer 100GB of free Google Drive storage for two years.
The Chromebook has the same design as HP’s other PC offerings, which mostly run on Windows and have standard-capacity hard drives. But, with a lot of data moving to the cloud, the Chromebook provides a different usage model.
“We see this as another device to be used around the house. It’s easily managed,” Conrad said.
No LTE On IBM’s SoC Until 2014
Intel is working on integrated LTE modems for its upcoming SoC designs, but CEO Paul Otellini claims they will not be ready for prime time until 2014.
In a recent conference call Otellini was directly asked about Intel’s plans for LTE integration and said “higher levels of integration” are expected next year. He went on to say that the first Intel-based phones with LTE should launch in early 2014, in time for the Mobile World Congress.
Otellini said Intel’s wireless team, formerly a business unit of Infineon, is making good progress in LTE.
“We believe we have a very competitive solution. The Infineon team is known for not necessarily being first to market, but being really good at engineering a very solid solution and being cost effective and cost competitive and I think that they are doing a very good job with respect to this product,” said Otellini.
TSMC 20nm Processors In High Demand
TSMC believes demand for next-generation 20nm chips will be even higher than demand for current 28nm products.
Speaking in a conference call, TSMC CEO Morris Chang said the volume of 20nm SoCs built next year will be greater than 28nm volume in 2012 and by 2015 it should be greater than 28nm volume in 2013.
TSMC hopes to start 20nm production in the latter part of the year. The company is constructing two new facilities at Fab 15 and it hopes to start 20nm production in both simultaneously. We could be in for a quick ramp.
TSMC will offer only one version of the 20nm process, compared to four versions of the 28nm process. This should also allow it to ramp up volume production faster, reckons Xbit Labs.
Broadcom Goes UltraHD

Comments Off on Broadcom Goes UltraHD
As TV manufacturers show off UltraHD TVs at CES, communications chip maker Broadcom is introducing the guts of future gateways that will be able to deliver video for those sets into viewers’ homes.
Broadcom’s BCM7445 silicon platform, announced just hours before the show opened on Tuesday morning, will be able to process incoming video from cable, carrier and satellite services that has four times the resolution of typical 1080p video offered today, according to the company.
Like the eye-catching but expensive TVs on the show floor in Las Vegas, the BCM7445 is just one of the first of many steps to consumers watching UltraHD shows at home. New content, displays and delivery technologies will all be required for the new resolution, which is also known as 4K.
Broadcom expects its chip to be in volume production by the middle of next year, in time for mainstream UltraHD TVs that will probably hit the market for the late 2014 holiday season, said Joe Del Rio, associate product line manager at Broadcom. However, service providers, which will probably be the distributors of most of the gateways built with the BCM7445, may take longer to start sending UltraHD video to their subscribers, Del Rio said.
