Will AI usher in a new era of hacking?

It may take several years or even decades, but hackers won't necessarily always be human. Artificial intelligence -- a technology that also promises to revolutionize cybersecurity -- could one day become the go-to hacking tool.  Organizers of the Cyber Grand Challenge, a contest sponsored by the U.S. defense agency DARPA, gave a glimpse of the power of AI during their August event. Seven supercomputers battled each other to show that machines can indeed find and patch software vulnerabilities.Theoretically, the technology can be used to perfect any coding, ridding it of exploitable flaws. But what if that power was used for malicious purposes? The future of cyberdefense might also pave the way for a new era of hacking.To read this article in full or to leave a comment, please click here

Japan plans superefficient supercomputer by 2017

Japan plans to build a super-efficient computer that could vault it to the top of the world's supercomputer rankings by the end of next year.With a processing capacity of 130 petaflops, the planned computer would outperform the current world leader, China's Sunway TaihuLight, which delivers 93 petaflops. One petaflop is one million billion floating-point operations per second.Japan's National Institute of Advanced Industrial Science and Technology (AIST) isn't just aiming to build the world's fastest supercomputers, it also wants to make one of the most efficient. It is aiming for a power consumption of under 3 megawatts -- a staggering figure, given that Japan's current highest entry in the Top500 supercomputer list, Oakforest-PACS, delivers one-tenth the performance (13.6 petaflops) for the same power.To read this article in full or to leave a comment, please click here

Linux hardening: a 15-step checklist for a secure Linux server

Gus Khawaja Most people assume Linux is secure, and that’s a false assumption. Imagine your laptop is stolen without first being hardened. A thief would probably assume your username is “root” and your password is “toor” since that’s the default password on Kali and most people continue to use it. Do you? I hope not.The negative career implications of choosing not to harden your Kali Linux host are severe, so I’ll share the necessary steps to make your Linux host secure, including how I use penetration testing and Kali Linux to get the job done. It’s important to note that, while they are many distributions (AKA distros) of Linux and each one differs from the command line perspective, the logic is the same. Use the following tips to harden your own Linux box.To read this article in full or to leave a comment, please click here(Insider Story)

Britain’s wartime codebreaking base could host a national cyber security college

Plans are afoot to build the U.K.'s first National College of Cyber Security at Bletchley Park, the birthplace of the country's wartime codebreaking efforts.It was at Bletchley Park that Colossus, the world's first electronic computer, was built during World War II to crack the Lorenz code used by the German high command.

10 smartphone trends to watch in 2017

Smartphone buyers have a lot to look forward to in 2017. Devices will be thinner, faster, and perhaps a bit more intelligent than you'd like. Virtual reality will spread to budget smartphones, and they will also have better graphics, higher resolution screens, and more storage. More than ever, you'll be using your smartphone to pay for products and log into websites. Deep learning could help smartphones get a fix on user behavior and improve the mobile experience. We could see a renaissance in smartphone designs, and wireless audio could replace headphone jacks in more handsets. USB-C will replace older connector and charging cables. Here are 10 smartphone trends to watch out for in 2017:To read this article in full or to leave a comment, please click here

5 burning questions about AMD’s Zen chip

AMD's Zen chip is just around the corner; it'll first come to gaming systems any day now. There's a lot of excitement about Zen, which AMD believes is its most important chip this decade.The high-performance Zen could put AMD back on the map as a legitimate competitor to rival Intel. AMD's chips in recent years haven't been as sophisticated as Intel's offerings, but Zen could bring AMD up to par. The AMD faithful are salivating over Zen, and even some Intel chip enthusiasts can't wait to give it a try.AMD CEO Lisa Su has said Zen would be available in a few gaming systems by the end of the year, but it doesn't look like that's going to happen. A more likely scenario is that systems will start coming early next year. Zen chips for servers will follow in the first half of next year, with Zen for laptops and other desktops coming later.To read this article in full or to leave a comment, please click here
