I build stuff and break stuff.

Congratulations @micronics3d on joining @formlabs! Still looking forward to a potential low-cost SLS solution (pretty please!)

@SamErde @mubix Dr. Barkley is the first resource I direct people to when they ask me about ADHD. He’s truly helped me understand my ADHD brain better than anyone else. Great resource!

AWS triggered the canary token on my GitHub profile over the weekend 🤔

Like the opsec of NightHawk but missing Aggressor-like scripting functionality? Check out DayBird, an extension I built for NightHawk to allow for automation of operator workflows and initial check-in actions via C# plugins.

@cdcaron Thank you for this excellent article!

Just published a new blog post covering how to hide Beacon during BOF execution. If your BOF triggers a memory scan then EDR is likely to find Beacon and kill your process, but we can mask it using a simple technique. https://t.co/HzVW5zzO5B

[Joel H @0ctagons]

@AlexLevin Sorry, I don’t know whether anyone is still there. Do you have a vulnerability to report?

[Joel H @0ctagons]

@kulinacs Skubernetes!

My new blog post! Dissecting and Exploiting TCP/IP RCE Vulnerability “EvilESP”. Reverse engineering CVE-2022-34718 + write a remote Denial of Service exploit. Covers IPsec and IPv6 fragmentation in the Windows kernel, bin-diffing, and making weird packets https://t.co/XR8qhoq1ub

[Joel H @0ctagons]

I was cleaning and came across one my favorite finds at the HPB warehouse sale in Dallas (many years ago). There are some cool examples in here, including a catalog of block diagrams for binary operations, like finding a square root.

@BakedSec @kulinacs @BakedSec you’re like the proto-bitter-old-man.

[Joel H @0ctagons]

I’m convinced that, if nothing else in this industry, reviewing reports will turn me into a bitter old man.

[chompie @chompie1337]

Demonstrating CVE-2022-37958 RCE Vuln. Reachable via any Windows application protocol that authenticates. Yes, that means RDP, SMB and many more. Please patch this one, it's serious!

Red teamers, when you're racing against the clock, stop letting DNS propagation slow you down! Use Invoke-Expression and Invoke-WebRequest for payloads instead. IWR is even proxy aware 🔥🔥

Bonus tip: downgrade to PowerShell version 2 for added stealth 💪

[Joel H @0ctagons]

@christruncer Crusader Kings III (not perfect but playable), Dome Keeper, Project Zomboid, Oxygen Not Included, Don’t Starve Together, Rimworld, Vanpire Survivors, and Terra Invicta have all been favorites of mine on the Steam Deck. Also, I can stream Xbox Game Pass games via MS Edge lol

[Joel H @0ctagons]

@vxunderground @backblaze Now is your chance to shine!

[Joel H @0ctagons]

4 x Nvidia Xavier NX 32GB modules: $2500. 4 x Active Heatsinks: $135. Reference Carrier Board: $169. Hardwired, bright-as-the-fucking-sun, non-adjustable, rainbow-colored LEDs in the cooling fan: priceless.

[Chris Shields @r00t0v3rr1d3]

I feel like I’ve been reading the same “TTPs” in every report for a decade now. Not really sure what to say.

[Joel H @0ctagons]

@ArtByAlida I asked them and they said no! In all seriousness, these are all Solenopsis invicta, a fully claustral species. Once a fully claustral queen has found a nesting place, they will almost never leave it again.

[Joel H @0ctagons]

If you’ve ever met me, you’d likely already know a few reasons why my buddy @anthemtotheego lovingly calls me a ‘turbo-nerd’. I fully accept this label, and would like to interrupt your infosec feed to share a non-computer hobby of mine: ants.

[Joel H @0ctagons]

That’s my ant thread. I hope I’ve inspired others to learn about these fascinating creatures. Special shout out to Mikey and the team behind @AntsCanada whose YouTube channel got me interested in the hobby nearly 10 years ago.

[Joel H @0ctagons]

If you are into 3D printing, you can also design and print a ton of different useful tools and enclosures. This hobby is surprisingly cheap! https://t.co/LxI2tCf16G
