Victor Garcia is a Security Consultant, Penetration Tester for Sword & Shield Enterprise Security. His primary role consists of conducting network vulnerability assessments, penetration tests, and web application assessments. He also performs social engineering assessments such as phishing campaigns, telephone pre-texting, and malicious USB drops. He has more than 8 years of experience in the technical field in roles such as help desk, network and system administration, auditing, and information security. Additionally, Victor holds a Bachelor’s of Science in Computer Engineering and has also obtained several Offensive Security certifications.

The last presenter we had from Sword & Shield, Russel Van Tuyl, hit it out of the park. Definitely looking forward to Victor’s presentation. Guessing that while low hanging fruit are great for pen testing, they might be so good for the rest of us 🙂

Cyber Security Forum: Web Service Security Best Practices

cyber-security-aug17_post-image

Hello all, this month’s RISE meeting will be a little different, in fact it’s going to be a lot different.  This month we are doubling up with the RBTC.  The RBTC will be hosting a Cyber Security Forum highlighting Web Service Security Best Practices on Tuesday August 8th from 5:30pm – 7:30pm at Virginia Western Community College.  The speaker will be Adam Memisyazici from Virginia Tech.

Not only will this provide a great opportunity to learn more about Web Security but this also provides a great opportunity to rub elbows with likeminded technologist from the Valley.  Please keep in mind that unlike our meetings the RBTC actually needs to you register for this event.  Click on the link provided and register quickly.  Also there is a minor cost to attend but they probably have better snacks and drinks than we do so it’s probably worth it.  In any case, if you can make it I encourage you to attend.

Lastly, I want everyone to understand that that this will not be the norm for us but I do feel that it is a good fit for us this month.  If this works perhaps we will do again sometime in the future, if it doesn’t, well we gave it a shot.   I have provided additional details below.  Please check them out.

Jan 2017 – Open Mic Night

open-mic

 

We had a great time at our December meeting trying our hand at the SANS Holiday Hack and we are planning on our next meeting being just as entertaining. This month we will having an “Open Mic Night” at ECPI on January 12th at 5:30pm.

Here’s how it works, collect those burning IT Security questions and bring them to the group. We will give everyone an opportunity to ask the group questions and then see what we as a group of security professionals can contribute as a whole. The idea is that one of us is never as smart as all of us so let’s share our questions and our knowledge to better secure the valley. If you don’t have any questions that’s fine, we still need you to share your experiences with those of us that do have questions.

We look forward to seeing everyone on Thursday the 12th at ECPI.

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

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.

Sept 2016 – Bad, Bad USB

We are in for a treat in September! Jeremy Dorrough is going to do an updated version of the presentation he did at DEF CON last year.

USB Attack to Decrypt Wi-Fi Communications

Jeremy Dorrough Senior Network Security Architect / Genworth Financial

The term “Bad USB” has gotten some much needed press in last few months. There have been talks that have identified the risks that are caused by the inherent trust between the OS and any device attached by USB. I found in my research that most of the available payloads for the USB rubber ducky would be stopped by common enterprise security solutions. I then set out to create a new exploit that would force the victim to trust my Man-In-The-Middle access point. After my payload is deployed, all Wi-Fi communications will be readable, including usernames, passwords and authentication cookies. The attack will work without the need of elevating privileges, which makes it ideal for corporate environments.

Bio: Jeremy has built his career around protecting assets in the most critical IT sectors. He started his career working in a Network Operations Security Center for the US Army. He then went on to work as a Network Security Engineer defending Dominion’s North Anna Nuclear Power Station. He is currently a Senior Network Security Engineer/Architect at Genworth Financial. He is a MBA, CISSP, CEH, GIAC GPPA, CSA CCSK, ABCDEFG… Blah Blah Blah.

Jeremy has spent over 10 years researching and implementing new ways to defend against the latest attacks. He enjoys creating new exploits and feels it makes him a more well-rounded defensive Security Engineer. He is happily married and a father to two soon to be hackers. When he’s not staring at a command prompt, he is busy building and driving demolition derby cars.
