Yet more reasons to disagree with experts on nPetya

In WW II, they looked at planes returning from bombing missions that were shot full of holes. Their natural conclusion was to add more armor to the sections that were damaged, to protect them in the future. But wait, said the statisticians. The original damage is likely spread evenly across the plane. Damage on returning planes indicates where they could damage and still return. The undamaged areas are where they were hit and couldn't return. Thus, it's the undamaged areas you need to protect.

This is called survivorship bias.

Many experts are making the same mistake with regards to the nPetya ransomware. 

I hate to point this out, because they are all experts I admire and respect, especially @MalwareJake, but it's still an error. An example is this tweet:


The context of this tweet is the discussion of why nPetya was well written with regards to spreading, but full of bugs with regards to collecting on the ransom. The conclusion therefore that it wasn't intended to be ransomware, but was intended Continue reading

Recruiters: Must Try Harder

Right now, it’s an employee’s market in the Bay Area. Technology firms are growing, and they’re always trying to hire more people. So I regularly receive emails from recruiters. This is not to brag, it’s just the way things are right now, based upon the economy, my background, my current location, and my age. I’m lucky.

Some of these approaches are outstanding. Well-crafted, tailored to the person and the role. Some are pathetically bad, and I don’t know why they try.

The Right Approach

A good approach goes like this:

Hi Lindsay!

I’m a recruiter at $CoolCompany. We’re looking for great people to work on our teams doing $InterestingThingOne and $InterestingThingsTwo! We’re hoping to do This, That and the Other Thing! Check out our projects on Github <here> and <here>.

We think this would be a good match because of your background working on $RecentProject in $PreviousIndustries.

We were thinking about someone to do these sorts of things: X, Y, Z. But mainly it’s about finding the right people, and we’re fine with re-working the role a bit to suit.

Let us know what you think

Regards, Good Recruiter

Latest Ransomware Techniques Show Need for Layered Security

I think everyone that touches security has had multiple conversations about the hardened edge and soft center, commonly found in networks. This usually accompanies some discussion around the overlapping concepts of difference in depth, layered security and security ecosystems. It seems like many of the recent exploits have used a C2 connection for instructions. In those cases, assuming a perfect NGFW product and configuration actually existed that caught 100% of the malicious traffic, it would have the capability to impact those attacks.

However on June 27, Cisco Talos published an article about a ransomware variant known as Nyetya. As of today, Talos has been able to find no evidence of the more common initial infection vehicles. Both Cisco and Microsoft have cited the upgrade process for a tax accounting package as the initial point of infection.

Per Cisco Talos:

The identification of the initial vector is still under investigation. We have observed no use of email or Office documents as a delivery mechanism for this malware. We believe that infections are associated with software update systems for a Ukrainian tax accounting package called MeDoc. Talos is investigating this currently.

So what does this mean to the majority of the world that Continue reading

InfiniBand And Proprietary Networks Still Rule Real HPC

With the network comprising as much as a quarter of the cost of a high performance computing system and being absolutely central to the performance of applications running on parallel systems, it is fair to say that the choice of network is at least as important as the choice of compute engine and storage hierarchy. That’s why we like to take a deep dive into the networking trends present in each iteration of the Top 500 supercomputer rankings as they come out.

It has been a long time since the Top 500 gave a snapshot of pure HPC centers that …

Fix Your NAS With Metadata

Enterprises are purchasing storage by the truckload to support an explosion of data in the datacenter. IDC reports that in the first quarter of 2017, total capacity shipments were up 41.4 percent year-over-year and reached 50.1 exabytes of storage capacity shipped. As IT departments continue to increase their spending on capacity, few realize that their existing storage is a pile of gold that can be fully utilized once enterprises overcome the inefficiencies created by storage silos.

A metadata engine can virtualize the view of data for an application by separating the data (physical) path from the metadata (logical) path. This …

Not The Cisco of John Chambers Anymore

I just got back from Cisco Live 2017 last night and I had a blast at the show. There was a lot of discussion about new architectures, new licensing models, and of course, Tech Field Day Extra. However, one of the most interesting topics went largely under the radar. I think we’re fully in the transition of Cisco away from being the Company of John Chambers.

Steering A Tall Ship

John Chambers wasn’t the first CEO of Cisco. But he’s the one that most people would recognize. He transformed the company into the juggernaut that it is today. He watched Cisco ascend to the leader in the networking space and helped it transform into a company that embraced voice, security, and even servers and compute as new business models.

John’s Cisco is a very unique animal. It’s not a single company. It’s a collection of many independent companies with their own structures and goals all competing with each other for resources. If John decided that UCS was more important to his goals this quarter, he shifted some of the support assets to focus on that business unit. It was a featured product, complete with healthy discounts to encourage user adoption.

Worth Reading: The impact of more specifics in the DFZ

Here I’ll examine the collected statistics of the use of more specific routing advertisements in BGP in further detail, looking at the impact of more specifics on the growth of the routing system and the dynamics of BGP updates in the larger context of scaling BGP to meet the demands of an ever-larger Internet. —potaroo

Momentum is Building for ARM in HPC

2011 marked ARM’s first step into the world of HPC with the European Mont-Blanc project. The premise was simple: leverage the energy efficiency of ARM-based mobile designs for high performance computing applications.

Unfortunately, making the leap from the mobile market to HPC was not an easy feat. Long time players in this space, such as Intel and IBM, hold home field advantage: that of legacy software. HPC-optimized libraries, compilers and applications were already present for these platforms. This was not, however, the case for ARM. Early adopters had to start, largely from scratch, porting and building an ecosystem with a …

Cisco’s DevNet extends the value of its intent-based networking

Earlier this month, Cisco held a media and press event to launch its intent-based networking solution. To no surprise, its user event, Cisco Live 2017 was all about the network as Cisco looks to get customers to think more broadly about the role of the network in digital transformation.Brandon Butler did a great follow-up post to mine that talked about why intent-based networking is a big deal. He called out a number of benefits, including streamlined operations and better security.To read this article in full or to leave a comment, please click here
