Malicious Script Delivering More Maliciousness – Because One Pile of Crap Isn’t Enough

Oh look, another bloody “innocent” script file that turns out to be a festering cesspool of malicious bullshit. Because apparently the Internet’s *main* goal is to keep us all neck-deep in ransomware-laced JavaScript wrapped in more obfuscated trash than a spammer’s wet dream.

So this poor bastard examiner at SANS spots a suspicious JavaScript file that some muppet probably opened thinking it was an “invoice” or “delivery notice.” Guess what? It’s not. It’s a nicely packed little gift box that launches PowerShell, fetches MORE malware, and then cheerfully sets about screwing your system six ways to Sunday. Shocking, right? I know, we’ve never seen *that* before. 🙄

The script hides its juicy bits through multiple layers of obfuscation – base64, weird ASCII code conversions, fake variable names that would make a regular coder cry, and enough nesting to make a Russian doll blush. Eventually it spews out PowerShell that drags down even more infected garbage from some scummy remote server. Because why infect once when you can go full Russian doll apocalypse?

Let me spell it out for the user population: if you don’t know what a file is, don’t open the goddamn thing. Stop clicking links, stop double-clicking attachments, stop believing every file labeled “invoice” is your long-lost payment. Every time you click that crap, a malware author somewhere gets their wings – and I get one more goddamn reason to curse humanity’s relationship with email.

In short: bad script = launches PowerShell = downloads more crap = ruins your day. Standard modern shitshow. The only real solution? Nuke it from orbit, block macros and scripts, and maybe, just maybe, stop giving dumb users network access.

Reminds me of the time some genius in accounting opened a “bonus_details.zip” file that turned out to be not-so-bonus ransomware. Two days of backup restores later, they still had the gall to ask if we could “speed up the Internet.” Sure, Karen, I’ll just rewrite TCP this afternoon between my therapy sessions.
