Dang, rough start for the Broncos. But they got this going forward! Might have a chance getting a new coach at FSU now. Seasons can only get better!

I always look forward to when we, CISA’s red team, gets to publish our reports, and today is one of those days! “A Tale of Two SOCs” - a story where we targeted two different orgs, with the same tradecraft, and very different responses. Read it! - www.cisa.gov/news-events/...

Man, I thought that might have been a 10-8 round for Mackenzie Dern. Solid start to the fight.

Welp, I was directly rejected for The Masters. I’ve been there twice and it was the best time ever. How’s everyone else looking?

I love it when I get a letter saying some information was likely taken in a breach by a company I never shared my data with or worked with. Great that all these companies just share with each other and then get owned.

Man, I try to watch the World Cup every time it starts. The amount of flopping and faking penalties kills me and just makes me continue to not be able to stand the sport. It’s miserable. The faking everything just sucks. Don’t even get me started about tie games.

There are other offensive services CISA does and there are other openings. But this one specifically is for red team, and we are every sense of that, an actual red team. We don’t do pen tests, mobile app reviews, etc. It’s one of the coolest missions you could join.

Our assessments last typically around 90 days. We get dev time to build out our tools to help ensure success on our assessments. We build our labs to model exactly what we are testing prior to prod. We don’t just take every “customer”, we can and do say no. The team is solid.

Figure I’d give more info. Our red team is a small team, but we target the entire federal government. We can also go after state, local, territorial, tribal, and critical infrastructure. Tired of everything being scoped out? We require everything is in scope.

You interested in hacking and want to red team the government? CISA’s red team has an opening! Our assessments are typically 90 days and we’re performing actual red team work here. Check out the opening, and let me know if you have any questions! usajobs.gov/job/871378500

I might be out of the loop, but sounds like ever since Nate Warfield left MSRC things have been rough (purely based on stories posted). We also don’t hear the inside story, so I’m sure there are two sides, but I really hope there’s some compelling info.

I cannot wait for this Strickland and Chimaev fight. The Avs lost, sad day, but now this fight should be solid. I think Strickland is losing, but I hope he wins.

I love what @PrivacyHQ does allowing you to generate one off credit cards. But I really wish they let you fund it without tying a bank account as the only source. Keeps me from diving in with it.

Man, I love Makar and MacKinnon, but boy did Makar make USA sweat after making that goal to tie it up, along with all the shots Canada had, including Toews.

To go off my previous post. I think testing AI is more than valid security testing. But in my mind red teaming is about testing defenders, detections, and improving response. When targeting AI, that isn’t it. It’s not red teaming. But I’m open to different opinions.

Chris Truncer @christruncer.bsky.social · 20/02/2026
So, question if the day from me. Can you “red team” AI? I’ve seen groups and people state that they red team AI. Is it more prompt injection? Are you actively helping defenders build and scale their defenses or test their responses? Is this more a pen test vs real red team?

Chris Truncer @christruncer.bsky.social · 29/01/2026
There are other ways to setup your system for telemetry if you are looking to see what can avoid detection. But if you want to test your latest hotness against prevention of code execution, definitely test it against WDAC. Find something that gets around it? Now that’s useful.

Chris Truncer @christruncer.bsky.social · 29/01/2026
WDAC will block everything you don’t trust, even to the point you could theoretically end up boot looping your Windows box if you’re trying to load untrusted drivers, or drivers you didn’t actually allow that you need. Ask me how I know….

Since a lot of talk I’m seeing lately is about good defenses, especially for initial access, I’ve been preaching the good news about WDAC (formerly my fav name of Device Guard) for a while. I think a properly set up WDAC is the bar which to test access - youtu.be/sWjhuVsSEks?...

I assume a lot of people have been playing with it, but I love testing and using @tailscale. It’s been nice being able to set up a private network, and love the wireguard usage overall. Anyone using it for anything niche or cool?

Just so everyone is aware, there’s 58 million pounds of corn dogs being recalled as we speak due to possible wood in the batter. You know, minus the giant wood stick it is embedded on. The more you know.

If you are running Spotify locally, and have something like LittleSnitch up, it sure is interesting to see how much tracking is going on with that app.
