Lojack Becomes a Double-Agent
Executive Summary ASERT recently discovered Lojack agents containing malicious C2s. These hijacked agents pointed to suspected Fancy Bear (a.k.a. APT28, Pawn Storm) domains. The InfoSec community and the U.S. government have both attributed Fancy Bear activity to Russian espionage activity. Fancy Bear actors typically choose […]Making art with SSH key randomart

SSH is everywhere in the development or operations world now. For development it’s what allows you to push to GitHub. For operations it’s what allows you to reasonably securely log into Linux servers.

Family Matters: Introducing the VMware NSX Portfolio
The new VMware NSX portfolio enables organizations to connect, secure and operate an edge-to-edge architecture and delivers networking and security services to applications and data wherever they reside.
This week at Dell Technologies World, Pat Gelsinger, VMware CEO, announced the new VMware NSX portfolio as part of the Virtual Cloud Network unveiling. The NSX networking and security portfolio provides consistent connectivity, integrated security, and the inherent automation to operate an end-to-end architecture that delivers applications and services everywhere. This innovative approach changes the way customers design and deliver services across their enterprises, and the NSX portfolio is the foundation upon which to build the Virtual Cloud Network. Leveraging the benefits of the cloud for the enterprise network is a fundamental shift from the past, where networking and security has relied on hardware-based appliances and features with limited automation abilities.
To support virtual cloud networking, organizations require a robust portfolio. Supporting our customers’ needs around any infrastructure, any cloud, any transport, any application, any platform, any device, we have been thinking about how we architect network elements that sit on top of those foundations. NSX has become a family brand to do just that from data center to cloud to branch Continue reading
VMware CEO Pat Gelsinger Preaches One Love, One NSX
During his Dell Technologies World keynote, Gelsinger detailed the company’s “vision for the future of networking.” That future looks like NSX.
VMware Welcomes Tom Gillis as SVP & General Manager, Networking and Security Business Unit
Back at Interop Las Vegas in 2013, less than one year after VMware acquired Nicira, then VMware’s chief architect of networking Martin Casado stated what was probably the understatement of the decade: “it’s a very exciting time to be in networking.”
With the birth of software-defined networking, pioneered by folks like Casado, the industry entered into a transformation unlike anything we’ve seen since the invention of Ethernet. The entire industry — from fascinating start-ups to the big players — rushed to challenge networking’s historical operational model, leveraging the power of software to help move networking into the future. Customers have embraced this model, where they can not only provision networking components in minutes without the need to modify the application, but they can also deliver micro-segmentation and granular security to each individual workload. It’s become a huge part of the success story for our customers, our partners and VMware ourselves.
Since then, we have continued to build out the portfolio with Software-Defined WAN, multi-cloud networking, hybrid cloud connectivity and network operations management and visibility solutions. And this week at Dell Technologies World, our CEO Pat Gelsinger laid out the Virtual Cloud Network, our vision for a software-defined network architecture Continue reading
Are Chatbots a Security Risk?
Chatbots – ingenious little bits of programming that have been making it possible for companies to automate the handling of queries, sales, and basic customer support. These bots are deployed through a number of different messaging platforms like Facebook Messenger, WhatsApp, etc.
And they have proven very popular. But, how secure is the tech? Lately, especially, there have been a lot of concerns raised. Say, for example, that I head out and use the Nordstrom app. I find the perfect pair of discounted sport shoes and want to buy them.
How safe am I entering my credit card details over the system? Or, more importantly, can chatbots be hacked?
Let's take a step back here for a second. Certainly, a chatbot is essentially just a program, and so, it makes sense that it could be hacked. But the danger is not likely to be any more than your local bank being hacked.
The same HTTPS protocols and metadata techniques used to provide security for the bank's site and messaging services can also secure the information transmitted via chatbots. The tech underlying the chatbot is similar, in fact, to your standard app, so it is not new.
The main difference here, Continue reading

Azure accelerated networking: SmartNICs in the public cloud
Azure accelerated networking: SmartNICs in the public cloud Firestone et al., NSDI’18
We’re still on the ‘beyond CPUs’ theme today, with a great paper from Microsoft detailing their use of FPGAs to accelerate networking in Azure. Microsoft have been doing this since 2015, and hence this paper also serves as a wonderful experience report documenting the thought processes that led to an FPGA-based design, and lessons learned transitioning an all-software team to include hardware components.
There’s another reminder here too of the scale at which cloud vendors operate, which makes doing a project like this viable. The bulk purchase of FPGAs keeps their cost low, and the scale of the project makes the development investment worthwhile.
One question we are often asked is if FPGAs are ready to serve as SmartNICs more broadly outside Microsoft… We’ve observed that necessary tooling, basic IP blocks, and general support have dramatically improved over the last few years. But this would still be a daunting task for a new team… The scale of Azure is large enough to justify the massive development efforts — we achieved a level of performance and efficiency simply not possible with CPUs, and programmability far beyond an ASIC, Continue reading
