Hey Community, I figured that I could strengthen existing automated unit test generation quality by integrating mutation testing results as a metric to determine the quality of my unit tests. Figured everyone should be unit testing their code now especially after the recent Crowdstrike fiasco.

Please star if you like it :)

Caused by security firm CrowdStrike that issued an update.

We're happy to announce that BusKill is presenting at DEF CON 32.

BusKill is presenting at DEF CON 32

via @[email protected]

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.

Golden DIY BusKill Print

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.

Regression in signal handler.

This vulnerability is exploitable remotely on glibc-based Linux systems, where syslog() itself calls async-signal-unsafe functions (for example, malloc() and free()): an unauthenticated remote code execution as root, because it affects sshd's privileged code, which is not sandboxed and runs with full privileges.

Contrary to what is stated on the polyfill.io website, Cloudflare has never recommended the polyfill.io service or authorized their use of Cloudflare’s name on their website. We have asked them to remove the false statement, and they have, so far, ignored our requests. This is yet another warning sign that they cannot be trusted.

If it ain't 'murican we ban 'em!

Guess all foreign cars should be next, what with all the telemetry and all...

A 22-year-old man from the United Kingdom arrested this week in Spain is allegedly the ringleader of Scattered Spider, a cybercrime group suspected of hacking into Twilio, LastPass, DoorDash, Mailchimp, and nearly 130 other organizations over the past two years.

im working on a decentralized chat app. i open sourced it to get feedback on the implementation.

for a project like this, its important for it to be open source in order to gain user confidence in the security. but i find that the project is too complicated for pro-bono security assessment work (which is understandable).

fiverr probably isnt the best place to find reputable support, but i wanted to see the prices. it seems to range from 50 to 5k+

i wont be getting the support any time soon, but id like guage an estimate. i havent done something like this before so any/all advice is appriciated.

i created a threat-model which may help: https://positive-intentions.com/docs/research/threat-model/

KrebsOnSecurity has been in intermittent contact with LockBitSupp for several months over the course of reporting on different LockBit victims. Reached at the same ToX instant messenger identity that the ransomware group leader has promoted on Russian cybercrime forums, LockBitSupp claimed the authorities named the wrong guy.

LockBitSupp, who now has a $10 million bounty for his arrest from the U.S. Department of State, has been known to be flexible with the truth.
