Code reuse exposes over 120 D-Link devices models to hacking

A recently discovered vulnerability in a D-Link network camera that allows attackers to remotely take over the device also exists in more than 120 other D-Link products.The vulnerability was initially discovered a month ago by researchers from security start-up firm Senrio in D-Link DCS-930L, a Wi-Fi enabled camera that can be controlled remotely through a smartphone app.The flaw, a stack overflow, is located in a firmware service called dcp, which listens to commands on port 5978.

What I learned playing prey to Windows scammers

“I am calling you from Windows.”So goes the opening line of the well-known phone scam, where a person calls purporting to be a help desk technician reaching out to resolve your computer problems. These Windows scammers feed off people’s concerns about data breaches and identity theft to trick them into installing malware onto their machines. The scam has been netting victims for years, despite the fact that none of what the callers say makes sense.I recently received such a call and decided to play along, to see how the scam evolves and who the players might be. Over a period of three months, I received calls on average of four times a week, from various people, all intent on proving that my computer had been hacked and that they were calling to save the day. I had multiple opportunities to try a variety of conversational gambits and to ask questions of my own. Here is what I found out about the Windows scammer underworld via conversations with “Jake,” “Mary,” “Nancy,” “Greg,” “William,” and others.To read this article in full or to leave a comment, please click here

Samsung's blazing-fast UFS storage could replace micro-SD cards one day

Samsung has announced super-fast removable data storage cards that could one day replace the slower micro-SD cards in devices.The UFS card, based on the Universal Flash Storage 1.0 Card Extension standard, will come in capacities from 32GB to 256GB. The storage media could be used in cameras, drones, robots, virtual reality headsets and ultimately, even mobile devices.There is a need for faster and high-capacity removable storage in electronics, and UFS media fits that requirement. UFS cards can blow away micro-SD media in performance by moving data in and out of the card much faster.Users will be able to read 5GB of data—or a full high-resolution movie file—in 10 seconds from a UFS card, Samsung claimed. A UHS-1 micro-SD card would take 50 seconds to do the same.To read this article in full or to leave a comment, please click here

Nvidia's GeForce GTX 1060 is a $250 GTX 980 killer

Nvidia’s more modestly priced graphics cards often roll out months after the more luxurious GeForce models. Look at the last generation: The GeForce GTX 960 debuted four months after the GTX 980 and GTX 970 exploded onto the scene. A few generations before that, the GTX 660 launched a full half-year after the GTX 680.But not the GeForce GTX 1060.Nvidia announced its new sweet-spot graphics card Thursday morning, a mere month after the launch of the GTX 1080 and GTX 1070, and hot on the heels of AMD’s surprisingly powerful, shockingly cheap Radeon RX 480—which no doubt spurred the speedy release.To read this article in full or to leave a comment, please click here

This is what your messaging app needs to be truly secure

You may love your messaging app, but your messaging app may not love your privacy and security. WhatsApp, arguably the most popular messaging app in the world with a billion users, made a significant step in April by introducing end-to-end encryption built on the Signal protocol, much to the chagrin of governments and police forces.Some apps are much further ahead in the security game than others. As you wade through the glut of messaging services available, these are the features to look for.End-to-end encryption Previously, encrypting messages in transit was considered good practice, but the standards have changed. Look for an app that encrypts messages from user to user, so the app developer itself can’t even read the contents of your communications. “That’s the biggest line of demarcation between tools that are at least serious about trying to provide good security versus the ones that aren’t quite there yet,” advised Joseph Bonneau, tech fellow at the Electronic Frontier Foundation (EFF).To read this article in full or to leave a comment, please click here
