Network Forensics

December – Burp Suite, Part 2, Pro Edition

/ roanokeinfosec

For December we have asked that Logan Diomedi return and give us an in-depth dive into Burp Suite.  As you may remember Logan gave us a quick overview of Burp Suite back in February and many of you requested more so here it is. 

Logan Diomedi and Burp Suite, Part 2, Pro Edition

Burp Suite is one of the many free tools available in Kali Linux.  Burp Suite allows anyone to test and verify their web applications using various techniques from initial mapping and analysis of an application’s attack surface, to finding and exploiting security vulnerabilities.  In this meeting Logan will show us how he uses Burp Suite in his “Red Teaming” pen tests and how you can use the tool to test your own websites.

December 10th @ 5:30pm; This will be a virtual meeting

If you’re not familiar with the challenge it is an annual event put on by Ed Skoudis and his team. It is essentially a game that involves a series of cyber security challenges designed to get you to learn a wide variety of skills. The team does a phenomenal job. It has elements for all skill levels and hints as you go along the way. Last year’s challenge was EPIC and I think my wife was ready to kill me if I didn’t stop playing. I’ll warn you, it can get addictive.

The challenges are kept online each year so you can continue to play, even if you didn’t complete it by the deadline. Here is last year’s challenge if you want take a look: https://holidayhackchallenge.com/ This link will likely update to the 2016 challenge on 12/9. If so, here is a list of past challenges: https://pen-testing.sans.org/holiday-challenge/

I can honestly say, after playing last year, I have looked forward to this year’s challenge all year long. My wife, maybe not so much, since I had my head buried in my laptop for 2 weeks last time 🙂 Here are just a few of the things I either learned about, or added skills to while playing last years challenge: sed, awk, scapy, python, JSON, SQL injection techniques,  numerous web application pentesting techniques, Burp Suite, mondoDB, firmware extraction, DNS CnC and data exfil. And when I wasn’t pulling out my hair, I had an absolute blast doing it!

Join us on 12/15 to work on the Holiday Hack Challenge. It is for all skill levels and you will be surprised how much you will learn. We will have wifi access available so everyone can work on the challenge. If you are a student and want to participate but don’t have a laptop, let us know and I will make arrangements so you will have somethig to work on.

To make the best use of the time at the party, go ahead and sign up for an account once the challenge is posted on 12/9.  You can start playing anytime after you get an account. I  also recommend having some sort of virtualization software on your laptop such as VirtualBox or VMWare Player, both are free. And having a VM running Kali set up. Or if Kali is your main OS you may want to have a Windows VM setup. All of that will aid you in the challenge.

As usual we’ll have beer/soda and snacks. Just bring your brains because you’re going to need them.

Notes from Oct 2016 Ransomware Meeting

notes

Special thanks to Brad at malware-traffic-analysis.net (http://www.malware-traffic-analysis.net/index.html), we used his examples for the October meeting. His site is an excellent resource for learning. He also posts updates and other malware related info on his twitter @malware_traffic.

Here is the traffic we walked through: http://www.malware-traffic-analysis.net/2016/05/13/index.html

And here is the solution: http://www.malware-traffic-analysis.net/2016/05/13/page2.html

To use Security Onion to analyze the traffic you can get the Security Onion ISO here and install it in a VM: https://github.com/Security-Onion-Solutions/security-onion/blob/master/Verify_ISO.md

Here is how to replay the traffic in Security Onion for analysis:

We also had some discussion on how to identify what different types of files really are, regardless of what the extension is; and also how you can carve them out of traffic streams using hex editors. To determine file types you use the “Magic Bytes”:  https://blog.netspi.com/magic-bytes-identifying-common-file-formats-at-a-glance/

Here are some resources on ways to extract files (file carving) from pcaps:

We talked about some quick ways to get info on IPs and domains when researching potential incidents. Here is a quick hit list:

Oct 2016 – Your Money or Your Data

/ roanokeinfosec

robbery-ransomware

Join us for an interactive forensics scavenger hunt analyzing a pcap with some of the latest variants of ransomware. We will be looking at how Angler EK can, and often will deliver multiple infections such as Locky, CryptXXX and even some unknown goodies.

This will be an interactive session and I will try to come up with some small goodies to give away for those that solve the pieces to the puzzle first. Please bring a laptop with Wireshark installed to participate. Wireshark is a free protocol analyzer and an excellent tool for you toolbox. You can download it here: https://www.wireshark.org/

If you aren’t sure how to use Wireshark you can review the notes from our May session about Wireshark. There are also some good tutorials on Youtube. These both use the old Wireshark interface, the new one looks a bit different. All of the concepts are the same, some of the menus have just been moved around. If you have it installed, and are familiar with it, the session will be a lot more beneficial to you.

The meeting will be on 10/13 at R&K Solutions, 2797 Frontage Rd NW, STE 1000, Roanoke, VA 24017 at 5:30pm. Google Maps.

Another great meeting with a lot new faces and a lot of familiar ones. Big “Thanks!” to David Raymond (@dnomyard) for presenting and ECPI for hosting. David was kind enough to provide us a copy of the slides, you can grab them here:

If you want some more practice with pcaps and malware definitely check out: http://www.malware-traffic-analysis.net/  Just be careful if you export HTTP Objectshazmat out of those as they do contain actual malware. Don’t infect yourself! 🙂

Brad (@malware_traffic), who runs that site, does an outstanding job posting tutorials as well as breakdowns of current samples and traffic patterns. He joined Unit 42, Palo Alto’s Threat Research group,which does some excellent in depth write-ups on malware. This write-up on Locky ransomware and Nuclear EK is a good example: http://researchcenter.paloaltonetworks.com/2016/03/locky-ransomware-installed-through-nuclear-ek/

Also, don’t forget the RBTC Vulnerability Management forum is coming up as well as RVASec. If you know of other “local” security events please email roanokeinfosec@gmail.com and we will get them posted to the site.

Last but not least, if there is a topic that you would like to request for a presentation please let us know. We will do our best to line up a speaker. Or if you can speak on a topic please let us know and we’ll get you in the line up!

Meeting info: May 12th, @6pm, at ECPI (directions below).

This meeting is a can’t miss opportunity for a hands on deep dive with Wireshark. David Raymond  (@dnomyard, bio below) who has previously spoken at Black Hat USA, RSA and Scmoocon will be presenting.

wireshark2

Wireshark is a great tool for quick-and-dirty network traffic analysis and it is widely used for network troubleshooting and incident response. In this hands-on discussion, we will review the basics of Wireshark and discuss capture filters, display filters, and basic protocol analysis. We’ll then go beyond the basics to talk about more advanced features of Wireshark and touch on some of the command-line utilities that come with it, such as tshark, editcap, mergecap, and randcap.

To get the most from the discussion, attendees should bring a laptop with the latest version of Wireshark installed.

ECPI  (5234 Airport Rd NW #200, Roanoke, VA 24012 or Google Maps) will be hosting the meeting and there will be some lab machines available for use by those without a laptop available.

David Raymond currently serves as Deputy Director in the Virginia Tech IT Security Office and Lab. In this position he helps oversee the security of the VT network, advises graduate students and undergrads doing cybersecurity research, and teaches courses in computer networking and security in the Department of Electrical and Computer Engineering. David holds a Ph.D. in Computer Engineering from Virginia Tech, a Masters in Computer Science from Duke University, and a Bachelors in CS from West Point. He has published over 25 journal and conference publications on a variety of topics and has spoken at numerous industry and academic conferences to include Black Hat USA, RSA, Shmoocon, and the NATO Conference on Cyber Conflict.
