Flaw in Realtek SDK for wireless chipsets exposes routers to hacking

The software that controls wireless networking chipsets made by Realtek Semiconductor contains a critical vulnerability that could allow attackers to compromise home routers.The flaw exists in a firmware component called miniigd that’s present in router models based on Realtek chipsets. The component is part of the software development kit (SDK) for RTL81xxx chipsets that Realtek provides to router manufacturers.The vulnerability was discovered by Ricky Lawshae, a researcher with Hewlett-Packard’s TippingPoint Digital Vaccine Labs (DVLabs) which runs the well-known Zero-Day Initiative (ZDI) bug bounty program.“An attacker could leverage this vulnerability to execute code with root privileges,” the ZDI team said in an advisory published Friday. Exploitation does not require authentication, it said.To read this article in full or to leave a comment, please click here

Ham radio attempts to fill communication gaps in Nepal rescue effort

Amateur radio has stepped in to fill communication gaps in Nepal, which is struggling with power outages and a flaky Internet after a devastating earthquake on Saturday killed over 5,000 people.The hobbyist radio operators, also known as ham radio operators or hams, are working round-the-clock to help people get in touch with relatives, pass on information and alert about developing crises ever since the 7.8 magnitude earthquake hit about 80 kilometers from Nepal’s capital city of Kathmandu.Ham radio sends voice or morse code messages across radio frequencies and has often helped in emergencies. It can work off solar power or low-voltage batteries, which means that the radios can continue to work even after smartphones and laptops are discharged, said Jayu Bhide, National Coordinator for Disaster Communication at the Amateur Radio Society of India, on Wednesday.To read this article in full or to leave a comment, please click here

Pebble seeks to tap the Chinese market

Pebble hopes to replicate in China the success it has had in the U.S., by working to build a fanbase for its smartwatches.Three years ago, Pebble’s first product launched on Kickstarter as a crowdfunded project that initially raised over US$10 million from thousands of backers.“We have always had a tight relationship with the people using the product, and our intention is to continue that in China,” said Eric Migicovsky, Pebble’s CEO in an interview on Wednesday.The Silicon Valley startup is still in the early stages of tapping the country’s market, and only a month ago it upgraded its software to support Chinese language characters. It also began offering its smartwatches as a crowdfunding campaign on local e-commerce site JD.com that managed to rake in almost 300,000 yuan ($49,000) from 1,400 supporters earlier in April.To read this article in full or to leave a comment, please click here

CloudFlare’s New Dashboard

When we started CloudFlare, we thought we were building a service to make websites faster and more secure, and we wanted to make the service as easy and accessible as possible. As a result, we built the CloudFlare interface to put basic functions front and center and designed it to look more like a consumer app than the UI for the powerful network it controlled.

Over time, we realized there was a lot more to CloudFlare. In 2011, we added the concept of Apps, and a myriad of additional performance and security features from Rocket Loader to Railgun were added too. All these additional settings got buried under a lowly gear menu next to each site in a customer's account.

While still easier to navigate than the average enterprise app, using our UI could be a frustrating experience. For instance, imagine you wanted to turn on Rocket Loader for multiple sites. You'd have to go to My Websites, click the gear menu next to one of your domains, navigate to CloudFlare Settings, select the Performance Settings tab, scroll to Rocket Loader, then toggle it on. Then you had to go back to My Websites and repeat the process again for Continue reading

Twitter blames weak sales on lackluster ads, drops forecast

Twitter failed to meet revenue estimates for the first quarter, and is lowering its expectations for the rest of the year, due to weaker than expected performance of some of its ads products, the company said Tuesday.Total sales for the period that ended March 31 were $436 million, Twitter reported, up 74 percent from the previous year. Analysts, however, were expecting sales of roughly $457 million, according to estimates compiled by Thomson Financial Network.The company’s stock plummeted by nearly 20 percent toward the end of trading on Tuesday, to around $42. Twitter typically publishes financial data after markets close, but they appeared online, apparently in error, during the trading session.To read this article in full or to leave a comment, please click here

DMVPN for IPv6

As you probably already know, every DMVPN network consists of multiple GRE tunnels that are established dynamically. At the beginning, every Spoke in the Cloud is supposed to build a direct tunnel to the Hub. Then, once the Control Plane converges, the Spokes can possibly build tunnels with other DMVPN device(s), of course assuming that our DMVPN deployment (aka “Phase”) allows for that. 

In most cases DMVPN tunnels will be deployed over an IPv4 backbone, interconnecting different sites running IPv4. But since GRE is a multi-protocol tunneling mechanism, we can use it to carry different protocol traffic, like for example IPv6. Frankly, in the newer versions of IOS code you could even change the underlying transport from IPv4 to IPv6. This basically means that you can use an IPv4 OR IPv6 network to tunnel IPv4 OR IPv6 traffic.

In this particular article I am going to discuss a scenario in which the Transport/NBMA network (“Underlay”) uses IPv4 addresses, but the goal will be to use the DMVPN to interconnect sites enabled only for IPv6.

As you can see from the topology below, our private sites are configured with prefixes starting with 2192:1:X::/64, and the VPN (“Overlay”) subnet used is Continue reading

The LG G4 smartphone wins on flexibility, loses on design

LG Electronics’ G4 is a high-end smartphone with a removable battery and a microSD card slot, but its design falls short when compared with other expensive devices.Last year, LG had a hit with the G3, thanks to its high-resolution screen and aggressive pricing, but the company may have trouble replicating that success with the G4, announced on Tuesday.The phone has a 5.5-inch, 1440 by 2560 pixel screen and a Qualcomm Snapdragon 808 processor, which isn’t as powerful as the Snapdragon 810. LG thinks the Snapdragon 808 offers a better balance between performance and power efficiency. The G4 feels fast enough, so the company might be on to something, and the screen looks impressive.To read this article in full or to leave a comment, please click here
