This bag of tricks may help stop a Locky ransomware infection

A malware researcher has found a few tricks to stop one of the latest types of ransomware, called Locky, from infecting a computer without using any security programs.Ransomware is malware that encrypts a computer's files. Users are shown instructions for how to pay a fee to get the decryption key. The costs can range from a few hundreds dollars to thousands, payable to cybercriminals in bitcoin.Locky is a relative newcomer to the ransomware scene, which computer security researchers first saw over the last few months. It is primarily distributed through spam messages that try to trick people into opening attachments, such as fake invoices.To read this article in full or to leave a comment, please click here

The Syrian Electronic Army was careless with Gmail, Facebook

If you're a hacker, it's a good idea to stay away from Facebook and Gmail to communicate with your colleagues.Three men, who allegedly were part of a multi-year hacking campaign executed by the Syrian Electronic Army (SEA), left a long digital trail that didn't make them hard to identify, according to court documents.The U.S. Department of Justice unsealed charges on Tuesday against the men, who are accused of hacking companies and defacing websites.The SEA, which emerged around July 2011, claimed credit for prominent hacks that sought to support Syrian President Bashar al-Assad. The group targeted the White House, Harvard University, Reuters, the Associated Press, NASA and Microsoft, among others.To read this article in full or to leave a comment, please click here

Include the why

whyI recently stumbled upon an interesting speech from 1984 by Charlie Munger of Bershire Hathaway fame. Charlie is Warren Buffet’s right-hand-man, and a straight talking genius in his own right. It’s a fairly long speech and Charlie has a few very interesting things to say, but one particular section on ‘explaining the why’ really struck home.
Here’s a brief quote:

….if you always tell people why, they’ll understand it better, they’ll consider it more important, and they’ll be more likely to comply. Even if they don’t understand your reason, they’ll be more likely to comply.
So there’s an iron rule that just as you want to start getting worldly wisdom by asking why, why, why, in communicating with other people about everything, you want to include why, why, why. Even if it’s obvious, it’s wise to stick in the why.

The ‘why’ is notably absent from most conversations in our high-tech sphere. I’ve wasted countless hours interpreting solutions to ill-defined or undefined problems. I’m guilty of writing many ‘why-less’ documents and emails also. Upon reflection, I can recognise the folly of not explaining the problem at hand before launching into the solution.
When I drop the reasoning and background and Continue reading

Startup Sigfox wins over a carrier as new radios battle for the future of IoT

Altice, a network operator active in the U.S. and across Europe, is betting on French company Sigfox to expand its machine-to-machine business even as it tests LTE-M, a narrowband version of the 4G standard slimmed down for the Internet of Things. One technology it won't touch, though, is LoRa, the fledgling standard backed by a number of mobile operators, including Orange and Bouygues Telecom, the main rivals of Altice's French subsidiary, SFR. Machine-to-machine communications already constitute a significant market for Altice, which connects 5 million machines or objects via its cellular networks and has 2,600 enterprise clients in this field, company executives said Tuesday.To read this article in full or to leave a comment, please click here

Starting a Blog on Open Software/Hardware + Networking

Today I’m jumping into water to start writing about some area where I have some half-decent background: the intersection of Open Software/Hardware and Networking.

Why?

You see, I’m a software guy. The pragmatical Linux/OpenSource fanboy kind. What that means? I have a formal degree on Computer Science, and wrote Linux drivers and software for embedded systems for 8 years. But I’m also a pragmatical guy: I know how to write kernel drivers, but I use a Mac laptop every day because I like things to work. For the last 4 years I have been learning a big from networking at Hewlett Packard Enterprise, where I have worked on networking (SDN, ASICs), and more recently on the OpenSwitch project.
