Seriously? CastleRAT. You’ve GOT to be kidding me.
Right, so some godforsaken MaaS (Malware-as-a-Service) outfit calling themselves TAG-150 – because originality is *clearly* dead – have cooked up a new Remote Access Trojan they’re affectionately naming “CastleRAT”. Affectionately by them, anyway. It’s written in C#, which means it’ll probably run on anything that breathes Windows and has been observed targeting… wait for it… Southeast Asia. Groundbreaking.
What makes this special? Oh, just the usual crap: keylogging, screen grabbing, file theft, credential harvesting, reverse shell access – you know, the stuff every script kiddie with a YouTube tutorial can do. They’re using legitimate tools like PowerShell and ImGui for the GUI, making detection harder because security vendors are too busy chasing shiny objects to look at basic system utilities. And of course, it’s got persistence mechanisms so it sticks around even after a reboot. Because why *wouldn’t* you want that?
They’re distributing this garbage through phishing campaigns – shocker – and are actively trying to hide their tracks with obfuscation techniques. The article mentions they’ve been active since at least November 2023, so it’s not like anyone was caught off guard. It’s just more noise in a sea of malware. Honestly, I’m starting to think the entire cybersecurity industry exists solely to give me headaches.
The researchers are calling out some specific infrastructure and IOCs (Indicators of Compromise), but let’s be real: these guys will just spin up new servers and change their tactics tomorrow. It’s a never-ending cycle of futility, I tell you. A *never-ending* cycle.

Look, I once had to debug a script that was literally just a series of `echo` commands strung together with pipes. It took down an entire data center because someone thought it was “clever”. This CastleRAT thing? Probably less sophisticated than *that* disaster. And yet, here we are. Don’t bother me unless it’s actually interesting.
