BusKill is presenting at DEF CON 32

What is BusKill?

BusKill is a laptop kill-cord. It's a USB cable with a magnetic breakaway that you attach to your body and connect to your computer.

Watch the BusKill Explainer Video for more info youtube.com/v/qPwyoD_cQR4

If the connection between you to your computer is severed, then your device will lock, shutdown, or shred its encryption keys -- thus keeping your encrypted data safe from thieves that steal your device.

What is DEF CON?

DEF CON is a yearly hacker conference in Las Vegas, USA.

Talk Description

BusKill is a Dead Man Switch triggered when a magnetic breakaway is tripped, severing a USB connection. I’ve written OpenSCAD code that creates a 3D printable file for plastic parts needed to create the magnetic breakaway. Should anyone need to adjust this design for variations of components, the code is parameterized allowing for easy customization. To assemble a BusKill Dead Man Switch cord you will need:

1. a usb-a extension cord,
2. a usb hard drive capable of being attached to a carabiner,
3. a carabiner,
4. the plastic pieces in this file,
5. a usb female port,
6. a usb male,
7. 4 magnets,
8. 4 pogo pins,
9. 4 pogo receptors,
10. wire,
11. 8 screws,
12. and BusKill software.

Full BOM, glossary, and assembly instructions are included in the github repository. The room holds approx. 70 attendees seated. I’ll be delivering 3 x 30 min presentations – with some tailoring to what sort of audience I get each time.

Meet Me @ DEF CON

If you'd like to find me and chat, I'm also planning to attend:

• ATL Meetup (DCG Atlanta Friday: 16:00 – 19:00 | 236),
• Hacker Kareoke (Friday and Sat 20:00-21:00 | 222),
• Goth Night (Friday: 21:00 – 02:00 | 322-324),
• QueerCon Mixer (Saturday: 16:00-18:00 | Chillout 2),
• EFF Trivia (Saturday: 17:30-21:30 | 307-308), and
• Jack Rysider’s Masquerade (Saturday: 21:00 – 01:00 | 325-327)

I hope to print many fun trinkets for my new friends, including some BusKill keychains.

Come to my presentation @ DEF CON for some free BusKill swag

By attending DEF CON, I hope to make connections and find collaborators. I hope during the demo labs to find people who will bring fresh ideas to the project to make it more effective.

The hacktivist group Anonymous Sudan claims to have breached Microsoft and stolen credentials from 30 million customers. Microsoft says they are lying. The group has done a lot of DDoS attacks, and claimed much bigger impact than they really have had. Exaggerated claims may lead to increased "panic state" at the top of the corporate food chain. How do you communicate about threat groups making bold statements like this to your higher ups or customers?

TL;DR: Is ISO27001 easy or am I just too dumb to see the complexity?

Hi!

Just wanted to start some conversation on a standard that's sorta kinda infamous where I'm currently at, the ISO27001 standard.

I got tasked with "polishing up an ISMS" for a company and while I can't go into details, I got basically a control name (from 27002:2022) and a description of "what we need it to do." Now that I got into it, I feel that I may be missing something. Most of their controls are "Limit access to server room" or "Make sure access is logged and not permanent."

Like, the standard is not difficult reading, but if they can explain to ME how the controls should look in the end, what am I missing? Is there some extremely difficult part? Or can I just say "Just make the creds timeout after a month. Source: dude trust me?"

If you were tasked with implementing ISO27001, did you encounter any specific hurdles that I may not see from where I'm standing? The only thing I can see after I got through all the controls was a feeling that this will be more expensive on time for the security teams.

Thank you for coming to my TED(x) talk.

I have found Excel to be quite useful for collecting data, doing summary analysis of logs, etc. I also liked this blog post from Mandiant, about using Excel to timeline artefacts with very different structure. It takes a bit of work using find, left, mid, right, concat, etc, but then it is quite useful! Another good thing is that a lot of people are better at creating Excel sheets than doing XPath queries.

Anyone else using Excel for DFIR, and how do you use it?

This is an excellent series on container security fundamentals by Rory McCune who is a bit of an authority in this field:

• part 1
• part 2
• part 3
• part 4

If we are going to build a good community, we need some content! Here's a new feature in Kusto I have found useful in Sentinel, making it easier to do geolocation lookups in queries: geo_in_from_ip_address.

If we all share a little trick or something we have recently learned now and then, this will be a useful community!

Whether you are a buyer of security services, or a provider of them, what metrics, visuals, information is actually important to customers? What is the preferred way to consume reports - emails, dashboards, PDF reports, chat bots, smoke signals? Any thoughts and inputs much appreciated!

Some more context around the .zip domains.

👋 Hello all! So, how big is your security organization and how are responsibilities split across teams?

I've been through I don't know how many reorgs and seen quite a few place, and while some patterns emerge it's always interesting to see how Security is split up.

In my current company we evolved from:

• 6ppl: one security team
• ~12ppl: one security team, distributed between two locations
• ~12ppl: infrasec team, appsec team
• ~30ppl: infrasec team, dir team, appsec team, risk/audit team
• ~60ppl: infrasec team, dir team, corpsec team, appsec tooling team, appsec consulting team, risk/audit team, compliance team

Hey everyone! Since we're creating a new community here, I'd love to hear who's here.

I've been doing security for a bit over 30 years now. Made it up to a divisional CISO, then climbed back down the ladder to find a good work/life balance. Currently part of the security leadership team at a large US bank. I run a couple of teams right now, including a firewall policy engineering team and a production support center of excellence. I'm looking forward to seeing what type of community we can build here.

But instead of pissing on them... Bravo for enlisting the help of @huntress to do a code review. This vuln is NOT being actively exploited... yet.
