AutoIT3 Compiled Scripts Dropping Shellcodes – Because Apparently Malware Authors Can’t Stop Being Lazy

So here’s the shitshow of the day — some useless tosspots are once again abusing AutoIT3, that scripting tool that was meant for automating boring Windows crap, not for spitting out malicious rat droppings. The article walks us through how these charming bastards are taking perfectly harmless AutoIT3 scripts, compiling them, and stuffing them full of malicious payloads that drop shellcode nastiness all over the place. Because writing *real* malware from scratch would be too much bloody work, right?

The researcher dug into a few samples and found that these things unpack embedded data in memory using the usual bullshit obfuscation tricks — XOR, compression, Base64… you name it, they’ve slathered it on like cheap mayonnaise. Eventually, the scripts dump or execute shellcode that connects back to some remote C2 (Command & Control) wonderland operated by script kiddies with too much time and too little actual skill.

The bottom line? AutoIT3 gets hijacked into being a Trojan factory, dropping payloads that turn infected systems into remote-controlled meat puppets. The article also goes through some ways to detect this crap — like using sandboxing, analyzing suspiciously large AutoIT compiled files (newsflash: real ones don’t usually weigh a metric ton), and peeking for signs of packed binary blobs inside supposedly “innocent” executables. Lovely. Another day, another pile of digital diarrhea to clean up.

If you ever see an AutoIT3 executable that’s got more mystery bytes than Windows updates in a bad week — just nuke it from orbit. It’s the only way to be sure.

Reminds me of that one time I found a user running a “productivity script” that turned out to be mining crypto in the background. I deleted it, deleted their profile, and then deleted their will to ever click “Run” again. Dumbasses.
