Attacks using TeslaCrypt ransomware intensify

Over the past two weeks security researchers have seen a surge in attacks using a file-encrypting ransomware program called TeslaCrypt, known for targeting gamers in the past.TeslaCrypt first appeared in March and stood out because over 50 of the 185 file types it targeted were associated with computer games and related software, including game saves, custom maps, profiles, replays and mods -- content that users might have a hard time replacing.In April researchers from Cisco found a weakness in TeslaCrypt's encryption routine and created a tool that could decrypt files affected by some versions of the program.To read this article in full or to leave a comment, please click here

A Few Cybersecurity Predictions for 2016

I’m a bit reluctant to blog about 2016 cybersecurity predictions as it seems like everyone is getting into this act.  Alas, this end-of-year tradition used to be the exclusive domain of the analyst community and a few industry beacons but now it seems like every security tools vendor in the world is reaching out to me to tell me what they see in their crystal ball. So with some hesitancy, here are a few of the things I expect to see after the proverbial ball drops (in no particular order):1.       Greater focus on cyber supply chain security.  Enterprise CISOs realize that strong cybersecurity extends beyond the corporate LAN and that cyber-attacks and data breaches could easily start with third parties with access to the network.  The OPM and Target breaches are two examples where cyber-adversaries simply compromised trusted business partners and used them as a beachhead to penetrate their targets.  At the same time, we’ve seen in increase in malware hiding in firmware, system BIOS, device drivers, etc., so servers, routers, storage devices, and network appliances could all introduce malicious code into an otherwise pristine environment.  I expect CISOs to extend Continue reading

Pentagon wants $12 billion to ‘kick the crap out of’ iWorld geeks from foreign regimes

What do you do if you are worried about killer robots? If you are the Pentagon and those killer robots belong to the Chinese and Russians, then you propose a $12 to $15 billion budget to fund your own AI army and next-gen weapon technology.The Pentagon’s plan for new tech, according to Reuters, will include “wearable electronics, exoskeletons, greater use of drones and manned aircraft working together, and mother ships that would send out mini-drones to execute military missions.”To read this article in full or to leave a comment, please click here

IncludeOS is now free and open source!

IncludeOS

Alfred Bratterud is Assistant Professor and PhD scholar at Oslo and Akershus University College of Applied Science where he is currently working full time leading the development of IncludeOS at the NetSys research group.

We’ve finally lifted the lid on IncludeOS, just in time for the IEEE CloudCom paper presentation recently. A preprint of the paper is available from our repo. However, we’ve done quite a lot of work since the paper was written, so here’s an update on what IncludeOS is now, and what you can expect in the near future.

It’s a bit like a JVM, but for x86 C++

A Java Virtual Machine is a portable language runtime environment. Java is portable across hardware architectures and operating systems because it uses a common instruction set. Once you’ve started a Java program, you can’t log into it (unless your program itself provides the facilities), and you can’t boot up any other programs inside it.

IncludeOS is like a safe language runtime for C++ programs, compiled into the x86 instruction set. This has the obvious advantage of removing one layer of abstraction, compared to Java: with hardware virtualization the code will execute directly on the CPU. Like with Continue reading

IDG Contributor Network: Device administration with Cisco WLC

I recently had to dive very deeply into doing device administration AAA with Cisco Wireless LAN controllers and the SourceFire/Cisco FirePower Manager software. Given the interest that others have shown, I decided to write this Blog entry to share my experience.How Device Admin AAA works on the Cisco WLC Device Administration with a Cisco Catalyst switch is capable of command-level authorizations. With the WLC, however, it is based on the sections of the menu system. It does not prevent access to those sections of the GUI, but instead prevents changes from being saved when inside a menu section that is not authorized. Figure 1 shows the different menus in the orange box, with three of the individual menus highlighted with a yellow box.  To read this article in full or to leave a comment, please click here

Security ‘net

The ‘web has been abuzz with security stuff the last couple of weeks; forthwith a small collection for your edification.

The man in the middle attack is about as overused as the trite slippery slope fallacy in logic and modern political “discourse” (loosely termed — political discourse is the latest term to enter the encyclopedia of oxymorons as it’s mostly been reduced to calling people names and cyberbullying, — but of course, putting the social media mob in charge of stopping bullying will fix all of that). But there are, really, such things as man in the middle attacks, and they are used to gather information that would otherwise be unavailable because of normal security provided by on the wire encryption. An example? There is no way to tell if your cell phone is connecting to a real cell phone tower or a man-in-the-middle device that sucks all your information out and ships it to an unintended recipient before forwarding your information along to its correct destination.

The list of aliases used by the devices that masquerade as a cell phone tower, trick your phone into connecting with them, and suck up your data, seems to grow every day. But Continue reading

Avoiding an ISSUe on the Nexus 5000

The idea for this post came from someone I was working with recently. Thanks Fan (and Carson, and Shree) :-)

In Service Software Upgrade (ISSU) is a method of upgrading software on a switch without interrupting the flow of traffic through the switch. The conditions for successfully completing an ISSU are usually pretty strict and if you don’t comply, the hitless upgrade can all of a sudden become impacting.

The conditions for ISSU on the Nexus 5000 are pretty well documented (cisco.com link) however, there are a couple bits of knowledge that are not.  This post is a reminder of the ISSU conditions you need to comply with and a call out to the bits of information that aren’t so well documented.

The two major ISSU conditions on the n5k are:

  1. You must unconfigure all Layer 3 features
  2. The n5k must not have any Spanning Tree (STP) ports in Designated state unless the port is an Edge port.

The first one is easy: the switch cannot be doing any routing. Even if the switch is Layer 2 only, this condition will still fail if any of the following are true:

What security pros want for the new year

It’s that time of year when we ask security executives in a variety of industries what they would like to include on their holiday wish lists.Some of the responses we received were in the realm of pure fantasy. For example, one security chief asked for technology tools that address all of the major security threats, don’t cost anything and have top-notch 7x24x365 support with response times inside 15 minutes!+ ALSO ON NETWORK WORLD Follow all of our predictions for 2016 +Most of the wishes submitted are a bit closer to reality, and some might even come true if factors align the right way. So, with the completion of another year approaching, once again we present a listing of what security executives say they are hoping for, as they continue in their mission to protect their organizations’ systems and data.To read this article in full or to leave a comment, please click here

Microsoft on Macs – ARGH!

I moved my Mum onto a Mac a few years ago, and the calls for support dropped off dramatically.  She’s a very non-technical user, but tries hard to get to grips with the modern technology.

She’s recently decided she’d like to put some photos in a Word document, and write a message underneath – to send round to people at Christmas, you know?  How hard can that be?

Over the phone, I told her to go to Photos, select the photo and do Edit | Copy from the menu.  Then go to Word and do Edit | Paste to put it in the document.

Nope.

Tried it on my Mac, and sure enough, Word doesn’t know there’s anything in the clipboard to paste!   But if you open anything else (e.g. Textedit) it works fine.

Not really sure whose problem this is, since Word is able to paste in an image that is not in Photos (i.e. an image on the hard disk).  Instructions for that are here:  https://support.office.com/en-in/article/Add-or-replace-a-picture-in-Office-for-Mac-2011-c0a7f0d4-ed59-4183-8fe1-ed615b94cf80?ui=en-US&rs=en-IN&ad=IN

For a novice user like mum, finding that simple things like cutting and pasting are broken is extremely confusing. Of course she thinks it is her Continue reading
