ClickFix and ModeloRAT: Because Users Are Still Dumber Than a Bag of Hammers

Oh brilliant. Just fucking brilliant. The shitheads have evolved again. Now they’ve figured out they can weaponize nslookup – that dusty old DNS diagnostic tool that’s been cluttering up Windows since before most of these script kiddies were born – to deliver their malware. And the best part? Your users are practically lining up to help them do it. ClickFix, they call it. More like “Click-and-You’re-Fucked,” but what do I know? I’m just the bastard who has to clean up the mess.

Here’s how this fresh hell works: Some wanker sends your precious users an email with fake error messages and instructions that read like they came straight from Microsoft’s own documentation. “Oh noes! Your system has a critical issue! Simply copy and paste this command into PowerShell to fix it!” And like Pavlov’s dogs trained on a keyboard, they fucking do it. The command runs a DNS lookup that looks innocent but actually encodes data into subdomain requests, exfiltrating credentials or pulling down the payload right under your nose. It’s DNS, for fuck’s sake – nobody blocks DNS unless they want an angry mob of users with torches and pitchforks complaining they can’t get to Facebook.

The payload? ModeloRAT. Sounds like a shitty Mexican beer, but it’s actually a remote access trojan that’s about as sophisticated as a brick through a window. It does all the usual malware bollocks – steals passwords, grabs screenshots, logs your keystrokes, probably judges your porn habits. The kind of crap that means you’ll be spending your Friday night rebuilding a machine while the idiot who infected it is at home watching Netflix, blissfully unaware they’ve just cost the company seven grand in incident response time.

But here’s what really makes me want to take up heavy drinking at 9 AM: this shit is effective. Your fancy next-gen firewall? It sees DNS queries and waves them through like a tired bouncer at last call. Your email security gateway? It doesn’t see shit because the instructions are embedded in a screenshot or PDF. And your users? They’d execute a command that says “rm -rf /” if you told them it would make their Excel load faster. We’re not dealing with sophisticated hackers here – we’re dealing with a fundamental failure of human evolution where the “don’t run random fucking commands from strangers” gene somehow got bred out of the office worker population.

The security industry’s response will be predictable: some vendor will slap together a “DNS Behavioral Analysis Platform” (only $50,000 per year!), management will stroke themselves raw over the pretty graphs, and they’ll still refuse to spend five minutes on actual security awareness training because “Brenda from Accounting is too busy.” Meanwhile, I’m stuck here blackholing domains at the DNS level and praying the next wave of morons doesn’t figure out how to use ping instead.

Had one of these beauties land on my desk last week. User ticket: “Followed IT support email to fix Outlook, now computer is acting weird.” Weird, you say? The machine had been beaconing every document they’d opened since 2017 to a domain named “microsoft-security-update-very-legit.ru” – because apparently that’s a totally normal TLD for Microsoft to use. I wiped the machine, restored from backup, and disabled their account. When they asked why they couldn’t log in, I told them their password had expired. Permanently. Last I heard, they’re still trying to get HR to understand that “the IT guy said my password is forever broken.” Good luck with that, Brenda. Good fucking luck.
