there is a game called "data center" on steam which let's you build and manage your own data center.
this is lowkey genius, the best way to educate people on a new trait. hyperscalers should learn a thing or two from "edutainment".
Currently seeing a surge on #CastleLoader malware being delivered through fake websites impersonating software used in enterprise environments such as Zabbix or RVTools (see photo 1 & 2). IOCS below 👾🔎
Please note that this campaign uses the same exact template lures of previous observed #Bumblebee campaigns back in Summer 2025, disappeared for some months. Efforts put into disrupting Bumblebee infrastructure could have made the folks behind these campaigns to migrate into other malware options such as observed CastleLoader
The CastleLoader builds, hosted on fake Github repos (see photo 3), are being delivered as EV cert signed MSI builds (also like the previous Bumblebee campaigns), leading to other malware such as NetSupport RAT. The abuse of EV certificates by this malware can be tracked on CertCentral by @SquiblydooBlog (https://t.co/KfhngzzuDM)

How to learn Active Directory…
Step 1. Setup your own lab. Setup laps, applocker, logon scripts, CA server, sccm, exchange, file shares etc the whole nine
Step 2. intentionally misconfigure it with tools like BadBlood and BadShares (I wrote this one) or just manually screw it up
Step 3. Find all the messed up stuff (PingCastle, scriptsentry (mine), locksmith, ADeleginator (me again), AppLocker Inspector (also me), PurpleKnight, etc etc). Included in this step is documenting the stuff you find and the root cause (makes good blogging/video content)
Step 3a. Try to exploit the bad stuff. This is optional but it’s super fun and I believe it’s helpful to know how threat actors may attack the stuff you find (also good content)
Step 4. Fix all the messed up stuff. Included in this step is documenting your process and the fix (again good content)
Step 5. Repeat until you can talk about XYZ without looking it up
Bonus - document your process and stuff you’re doing on social media. Write blogs, make videos, whatever. Post daily.
Do this consistently for 1 year without looking up and I bet you’ll be surprised how far you go in just 12 months.
PS - This isn’t the only way. This is just what I’d recommend based on what’s worked for me and seeing others learn this way 🙏
