Read “Effective Threat Intelligence: Building and running an intel team for your organization”.

Recently I read the kindle version of “Effective Threat Intelligence: Building and running an intel team for your organization” by James Dietle (Amazon Affiliate Link). I found out after the fact there was a paper back version of it, and even gave one copy away as a Christmas present.

Anyway, this is the book I wish I had in January of 2016, when  I moved from Incident Response / Event Analysis to Threat Intelligence. It’s a good primer on the subject. While it’s not completely new material, it’s the basics in one place. When I started doing TI, I had to learn from the ground up, and things were scattered. Some was easy, other parts were more advanced, and nothing made a good how to. Especially when I wanted to start showing value from the word go.

I think that if I had, had this book and read it when I was starting it would have been very beneficial. While it’s not as in depth as SANS For578,  I do think that it would make a good primer for anyone in IR going to SANS for Cyber Threat Intelligence.

Doing OSINT

Leave a reply

The other day I mentioned Sailing the Sea of OSINT. Then in a Facebook group I’m in, they posted the BBC article about Ambulances Jamming car radios. In the group we made some speculations. But having a bit of a radio background, HAM Radio, CB Radio, and Broadcast Radio in college. I know how some of systems work.

So I went and dug up several articles on their pilot program. None however said how they worked. Just that they worked with the RDS radios in some cars. So I went and looked up RDS. Radio Data Systems, and the similar Radio Broadcast Data Systems in North America, is a protocol for sending data over the airwaves along with an FM signal.

In this case of both, they use PTY tags to associate what the data is. This is the same system that displays  the radio system call sign and song title on some radios. It can do more like say what type of music station it is based off the tags they use. This would allow people to search by genre.

However when they made the protocol they included a tag for Alarms (in the EU) / Emergency (in North America).

Reading up on the receivers with the RDS protocol / system built in they are designed to switch to the frequency broadcasting the Alarm / Emergency tag. Even if the radio is playing a “cassette” (which tells you how old this protocol is), a CD, connected via Bluetooth. Basically, if an RDS equipped radio is turned on it will tune to the station for the frequency the ambulance is broadcasting to.

The neat parts of this, the goal is to make it 10 to 15 seconds of alert, based on the speed of the ambulance. Which tells me the broadcast switch is tied to the Light and Siren switch, as well as either the ambulances GPS or ODB-II port, and the broadcast power is associated off that.

The people that came up with the idea said because Ambulances are getting stuck in traffic and or people are having accidents trying to get out of the way.

This is probably one of the items that really should be considered in Autonomous cars.

Review of “Sailing the Sea of OSINT in the Information Age”

Leave a reply

Just read, or re-read “Sailing the Sea of OSINT in the Information Age” by Stephen C. Mercado from the Studies in Intelligence Volume 48, number 3. I’ve had this for a while, I bought it 2013. Which is part of why I don’t remember if I read it before. It’s available from the CIA’s Library. It’s an article from the CIA’s Peer Reviewed Journal.

I found it very informative, even for something originally written in 2007.  While today, I think most of us in IT, think of OSINT as mainly tracking social media accounts (what some call SOCINT), it really goes beyond it.

The main points that were brought up:

  1. OSINT has been there for a very long time, since the beginning of Intelligence programs in the United States. It just hasn’t ever been formally given a department like others.
  2. It’s based off public media like magazines, books, news papers, radio and TV broadcasts.
  3. There are not enough people who understand foreign language / culture to get proper use out of OSINT.

There is things in the public space where OSINT lives that comes out better than in some of the other sources of intelligence. An example was information gathered by the Japanese about a former KGB officer.  “The resulting book and Levchenko’s press conferences were, according to a US intelligence officer, more revealing than his CIA debriefing”.

Which oddly ties in to something I saw on my Firefox browser recently.

So I’m curious, do we as a mono-langauge culture really have the skills we need to do intelligence. How many data leaks are found on foreign language hacking forums?

 

 

 

The article is worth the read, and brings up some good questions. I liked Mercado’s recommendation on making the Foreign Broadcast Information Service an intelligence service again, put OSINT under it, like how the NRO has IMGINT, and create incentives for people to study things like language and culture to increase the ability of the agency.

You can’t buy threat intelligence, or yet another “article” on Data vs Information Vs Intelligence.

The background:
This is a blog post I’ve been meaning to write for a few months now. It’s based in part off a twitter conversation that carried over in to a phone call. It is also something I’ve personally observed, a trap I fell in to, and heard other Threat Intelligence people say they observed. And while reading Cyint’s favorite tweets of 2016, I finally decided to sit down and write.

In the tweet list was a tweet was from Alex Pinto asking ‘how many more #ThreatIntel articles do we need about the difference between “data”, “information” and “intelligence”?’

So my answer is, as many as it takes to break out of our own echo-chamber / choir and figure out how to talk to our Cybersecurity peers and the stakeholders. So everyone is able to understand what is being bought. So here is yet another article talking about Intelligence vs Data Feeds being sold as Intelligence.

The Problem:
Companies are selling data feeds while calling it intelligence.

Script(s) to ping a computer

Leave a reply

I re-wrote a script I use at work. It was a messy bit of Python 3 previously. While it’s still not the cleanest of python scripts, it scratches my itch. It was originally just a straight line of commands with lots of repeated code. I made some functions and made it a little more modular. I know I need to learn PEP8, and start following it. This was just to improve something that I wrote previously with things I learned from Automate the Boring Stuff with Python.

I’ve shared it via my GitHub repository for DFIR scripts. They’re clean (not tied to any company). There is only Computer Ping for right now. There are 3 scripts all based on the same idea.

Ping a computer, if it is down, keep trying every 10 minutes for 1 hour. Pop an “alert” if the target is up, or the script finished before it came up.

  • 1 version for Windows running python (wComputerPing.py)
  • 1 version for Windows running Cygwin (cwComputerPing.py)
  • 1 version for boxes running Linux. (lComputerPing.py).

I’ll write others and upload to the repository as I have time / re-write stuff I use. They might not all be Python, but my goal is to be more Python than not.

Why I don’t have a lab

Leave a reply

An industry mailing list I’m on recently had a conversation that started asking about Master Degrees but had some hiring managers chip in. They said a question they tend to ask is to have the candidate tell about their home lab.

I’ve been asked this question a few times in the past, and I’ve asked people this question in job interviews. I know it’s to find out what kind of passion the candidate has for the job, but I think it’s starting to become a bad question to ask.

Here is why I don’t have a home lab.

Reading Malware Traffic Analysis

Leave a reply

I’ve made it through the June and July 2013 posts on Malware Traffic Analysis. I’m starting to understand his process more, and partially how he came to follow that process.

Mainly from what I could tell, and was confirmed in the blog posts, and via twitter, The site explodes malware on systems and gets pcaps for those systems. Then looks to see what call outs are there. The exercises and blog posts, so far, have only shown 1 ip address. Which makes it easier than a full corporate network to find the traffic.

Something I noticed. While Malware Traffic Analysis says to configure Wireshark one way, the blog posts of late show it’s now configured a little differently.

CSEC630 Lab 2

Leave a reply

Ok. The lab was pretty much what I expected.

Click this Panic button to reset everything. Go look at this pcap in Wireshark. Run this command in cmd.exe (and even walks the student through opening a term window by go to the start button, type cmd in the run box).

Run Snort with the test option on a pre-defined rule set using the pcap you looked at. Modify the same rule multiple times, enabling and disabling an alert each time. Run to see the difference.

Answer these 10 questions.

The last question was how to improve the class… I forgot to say use a Linux VM instead of a Windows VM. Since one of my answers did require Grep. Which means copy and paste from the VM lab to my box connected to the lab.
