Ransom attacks likely to fade as small email providers resist

The spate of cyberattacks against email providers is likely to pass with time as they refuse to pay ransoms. But that doesn't mean the attacks haven't cost them. Since early this month, the list of companies that have been attacked has grown longer: first ProtonMail of Switzerland, followed by HushMail, RunBox, VFEmail, Zoho and FastMail of Australia. The companies have typically received extortion requests by email asking for 10 or 20 bitcoins in exchange for not being subjected to distributed denial-of-service (DDoS) attacks. DDoS attacks involve sending a large amount of data traffic to a company's network, causing the service to choke and go offline.To read this article in full or to leave a comment, please click here

Don’t trust that USB drive!

Picture this: You go to a trade show and you collect your allocation of freebies: Teeshirts, hats, USB drives, and so on. You get  back to your room or, more likely, you get back to your office and you start sorting out your haul of tschotskes. You plug one of the nerd sticks into your computer and then this happens: Suddenly your day has taken a nosedive. To read this article in full or to leave a comment, please click here

Cybercriminals turn to video ads to plans malware

Cybercriminals have been delivering malware through online display ads for years, but they appear to be making headway with a new distribution method: video advertisements.Both methods of attack, known as malvertising, can have a broad impact and are a major headache for the ad industry. A single malicious advertisement, distributed to several highly trafficked sites, can expose tens of thousands of computers to malware in a short time.Some ad networks and publishers have taken steps to vet their ads more thoroughly, but criminals are constantly on the lookout for weaknesses.An attack detected about two weeks ago shows how cybercriminals are showing more interest in creating malicious video ads.To read this article in full or to leave a comment, please click here

Robot keeps stores stocked with Doritos

An autonomous robot was unveiled this week that can make sure that when you're hankering for Doritos, there's a bag waiting for you at the market.Simbe Robotics, based in San Francisco, announced its first product, a 30-pound robot called Tally that can move up and down a store's aisles checking inventory.

Tally also is set up to work during normal store hours, alongside employees and customers."Tally performs repetitive and laborious tasks of auditing shelves for out-of-stock items, low stock items, misplaced items, and pricing errors," the company said in a release. "Tally has the ability to audit shelves cheaper, more frequently, and significantly faster than existing processes; and with near-perfect accuracy."To read this article in full or to leave a comment, please click here

Lapsed Apple certificate triggers massive Mac app fiasco

A lapsed Apple digital certificate today triggered a massive app fiasco that prevented Mac users from running software they'd purchased from the Mac App Store. "Whenever you download an app from the Mac App Store, the app provides a cryptographically-signed receipt," explained Paul Haddad, a co-founder of Tapbots, the company behind the popular Tweetbot Twitter client, in an email reply to questions today. "These receipts are signed with various certificates with different expiration dates. One of those is the 'Mac App Store Receipt Signing;' that expires every two years. That certificate expired on 'Nov 11 21:58:01 2015 GMT,' which caused most existing App Store receipts to no longer be considered valid."To read this article in full or to leave a comment, please click here

IDG Contributor Network: How vulnerable are the internet’s undersea cables?

With a recent New York Times article expressing concern from military officials that some undersea internet-carrying cables are susceptible to submarine-attack by Russians, a few questions come to mind:Should we be worried? Just how much data do these cables carry? And where are they anyway?Mariners "Not many people realize that undersea cables transport nearly 100% of transoceanic data traffic," writes Nicole Starosielski in The Conversation.To read this article in full or to leave a comment, please click here

Magic or Curse? World TV day 2016

The Big TVImage by REUTERS/Kim Hong-JiThrough the years television has been celebrated and denounced for its influence. In 1996 the United Nations designated November 21 as World Television Day “not so much a celebration of the tool, but rather the philosophy which it represents. Television represents a symbol for communication and globalization in the contemporary world,” the UN stated. While in the US and other countries TV is decidedly high-tech, other places it is not.

EU wants US companies to report intelligence agency data access requests

The European Union wants U.S. businesses to report when U.S. intelligence agencies request access to data they hold about Europeans; the reporting is one of the conditions EU negotiators are imposing for signature of a new Safe Harbor agreement. Since Edward Snowden's revelations about the U.S. surveillance of Internet traffic, European Commission officials have been negotiating better privacy protection for Europeans' personal information transferred to the U.S. But since the Court of Justice of the EU struck down the 2000 Safe Harbor data transfer agreement last month, the negotiations have become more urgent. More than 4000 U.S. companies relied on the agreement to process Europeans' data, either for their own use or in order to deliver services to European businesses, and although other legal mechanisms exist allowing them to continue operations, those mechanisms are also increasingly falling under suspicion.To read this article in full or to leave a comment, please click here

Half of U.S. businesses have no formal BYOD policy for security

Years after the widespread adoption of workplace smartphones, more than half of U.S. companies said they have no formal BYOD (bring your own device) policy to safeguard their enterprises, according to a survey. The survey of 447 businesses of all sizes was conducted over the summer by systems integrator Champion Solutions Group. It found that 53% of those businesses haven't implemented a formal BYOD policy, while more than one-fourth confessed they have no systematic security approach, much less a formal policy. The survey findings are "ridiculous … surprising," said Champion CEO Chris Pyle, in an interview. Mobile security best practices have been promulgated by analysts and security firms for more than a decade to protect sensitive corporate data, but there is apparently widespread variation about how companies implement security for BYOD workers.To read this article in full or to leave a comment, please click here

Juniper’s Second Run up the Open Networking Mountain

Juniper’s announcement last week that it was launching Junos Software Disaggregation reflects a customer drive towards separating networking software and hardware, one that it was first evident Juniper was listening to with its OCX1100 announcement in early 2015. While the OCX announcement introduced this as a possibility, Juniper’s latest announcement ups the game, pointing out that customers are requiring the ability to procure networking hardware from sources other than Juniper.

Gartner agrees. In their recent report (Brite-Box and SDN Are Driving Innovation and Data Center Network Savings, 2015), the disaggregation benefits were highlighted as “enterprises to standardize network operations”, where organizations can “achieve life cycle savings of 25% to 50%”.

Cumulus Networks kick started this revolution in partnership with industry leading brite-box providers such as Dell, HP, and Quanta, with over 2 million ports in production. So while we are excited to have Juniper join the Open Networking revolution, a closer look suggests this could be another half-hearted attempt.

Based on the launch references, here are a few questions to ask your Juniper rep:

  1. Juniper says its disaggregated Junos software can run on “Open Network Install Environment (ONIE) compliant third-party switches.” Without a third party Continue reading
