Slow Mover

network forensics

Another problem from the 5th annual Army Cyber Skills Challenge.  The problem is called slow_mover and can be found here.

Your boss just handed you this PCAP that one of your network sensors captured. He’s positive that there is something fishy going on here but has no clue what it is.

Officer or Warrant Officer Post Military Retirement Employment

Let me lead with a little insight into my current situation. I am an Army Chief Warrant Officer 3 that is retiring from the Army after 20 years of active duty service. I have attended the Transition Assistance briefings and classes provided by my local installation. But, these classes are very basic and for everyone. The VA briefings do distinguish the differences in benefits between those that ETS and those that retire but that is the extent of any differentiated training between two types of Soldiers exiting the Army. The information about when I, as a commissioned officer, could start employment was very much discovery learning.

Tough Lessons

Army Runners

I want to take a little time today to talk about a few good lessons I’ve learned over the last few months.  Over the years, I’ve written a lot about various technical lessons and skills that I learned but recently I learned a few lessons about managing your career, and what life after the Army is like.  So I haven’t put this out to many people but not to long ago, I was in the process of being chaptered out of the Army.

We’re Mobile Friendly

I’ve had a number of things on my todo list for a while.  One of them has been to update Signal-Chief to make it mobile friendly because I’ve noticed that a fair number of people tend to check us out with their cell phones or tablets.  At long last, I have finally done that.  I just got done creating a new Wordpress theme based on the Foundations framework.  This allowed me to make the site adaptive to various screen sizes very easily so you can read it regardless of what device you are using to check it out.  Additionally, I also upgrade the server that I host off of to hopefully make it perform a little bit better.  Take a look around and let me know what you think.

Congress Blames the Wrong Guy

A couple of days ago, I posted an article about some some possibly non-public military locations being discovered after fitness tracker company Strava put up a heat map of their users activity.  In the 48 hours or so that has passed 9 Democratic members of congress wrote a letter to Strava asking for information.  The letter makes a number of statements and asks questions that I think look to shift the blame of all of this on Strava instead of the military and the individuals who were wearing fitness trackers and publicly broadcasting their location information.  I will go through a number of points and include my own response.

Spilling the Beans

I am in Augusta for the next few weeks for the ARCYBER Work Role Working Group (WRWG) and some training.  While I was waiting for my plane yesterday, I came across a story in my news feed talking about how publicly available GPS data may have exposed the location of classified US bases overseas
