Webcast: Introducing Competitive Backdoors & Breaches and More! Feb 12, 2020

Show notes

Backdoors & Breaches kind of took off. In case you don’t know, Backdoors & Breaches is an Incident Response Card Game to help people better understand the various attacks and defenses used in security today. We have sold out twice on Amazon, given out thousands of copies for free at conferences, and sent 2,000+ free decks to infosec educators (with a few thousand more decks to go). As a standalone game, with an Incident Master driving the narrative, it works really well. However, we have something else that we have been working on… Competitive Backdoors & Breaches. Yes, you can play this game against your co-workers. It just takes at least two decks. In this live webcast, we will be covering: advice for being an Incident Master; playing the regular game with remote teammates; answering many of your questions about gameplay; and introducing the rules on how to play this game competitively against another player.

Webcast: Passwords: You Are the Weakest Link Jan 17, 2020

Show notes

https://media.blubrry.com/bhis/content.blubrry.com/bhis/BHIS_Podcast_Passwords_Youaretheweakestlink.mp3 Why are companies still recommending an 8-character password minimum? Passwords are some of the easiest targets for attackers, yet companies still allow weak passwords in their environment. Multiple service providers recommend 8-character minimum passwords based on outdated data. Download Slides: https://www.activecountermeasures.com/presentations Originally recorded as a live webcast on December 5th, 2019 Presented by: Darin Roberts & CJ Cox Because of newer attack methods and increased computing power, password minimums need to be increased to 15 characters to keep networks safe. On this BHIS Webcast, Darin & CJ discuss: * Current password policies: BHIS recommendations, Microsoft, Google, Apple, NIST * Why do we recommend 15 characters – brute force, password crack, LM Hash * Passphrase vs. password * Recommended password policy summary Wild West Hackin’ Fest – Most Hands-On Infosec Con!

Webcast: Sacred Cash Cow Tipping 2020 Jan 14, 2020

Show notes

Want to learn how attackers bypass endpoint products? Download slides: https://www.activecountermeasures.com/presentations/ 3:41 – Alternate Interpreters 9:19 – Carbon Black Config Issue 15:07 – Cisco AMP EDR – Quick and Easy Bypass 18:24 – PowerShell AMSI Bypass – Rhino 19:07 – CylancePROTECT Bypass 24:14 – Windows Defender and Carbon Black Bypass 30:36 – Windows Subsystem for Linux 39:59 – PowerShell HTTP Web Cradle for Downloads Last year we came to the conclusion that we are going to keep going with the Sacred Cash Cow Tipping Webcast series. Why? Because many in the industry still believe that security is something that can be achieved through the purchase of a single product. To that end, we feel there is still a need to deconstruct certain parts of security (like AV) and show that there are always structural weaknesses in every security product that is implemented. This is becoming even more important now that many of the advanced endpoint products are not just fire-and-forget but have an endless array of different configurations that enable a company to shoot themselves in the foot by reducing the overall effectiveness of these products. So, yes, Sacred Cash Cow Tipping is more important than ever. To that end, our next webcast will be on bypassing endpoint security products. The goal of this webcast is to help show people that there is still no silver bullet in security. We also desperately want to show that configuration and monitoring still matters. This is our first webcast of the year. It may run longer than 60 minutes. It will be recorded. We will have a team of Black Hills Testers answering questions throughout the webcast. We have room for 3,000 attendees, so you will be able to attend live if you want. Wild West Hackin’ Fest – Most Hands-On Infosec Con!

BHIS Podcast: Py2K20 - Transitioning from Python2 to Python3 May 31, 2019

Show notes

In this podcast (originally recored as a live webcast), we talk about the 2020 End of Life for Python2. We address what the short, and medium term impacts will likely be. Key language differences will be highlighted with techniques to modify your code to be forward compatible.

As a SANS instructor teaching SEC573: Automating Information Security with Python, over the past three years, I have steadily moved my teaching materials, examples, demonstrations and personal coding to Python3. In this process, I have had to break habits and learn new habits to write Python3 compatible scripts. I also spend considerable effort showing people how to write Python2 scripts which are forward compatible with Python3 in order to ease the transition.

The largest barrier that most people struggle with is the idea that Python3 has changed the default string encoding to UTF-8 rather than simple byte encoding. Once you learn how to manage your string objects, the remaining transition issues are mostly modern improvements to the language which most people consider advantageous to adopt.

Since Python2 will no longer have active releases after 2020, it is important to embrace the change and move forward with the Python scripting community.
