ConsentFix Phishing Debrief – Because Apparently Clicking “Allow” is Rocket Science

Oh for fuck’s sake, here we go again. Some clever cyber-goblins have cooked up yet another scummy OAuth phishing campaign, this time going by the oh-so-professional name “ConsentFix.” What these rat-bastards do is send out sneakily crafted OAuth consent requests that look all official and friendly, asking users to “authorize” access through legit-looking Microsoft apps. And of course, the gullible masses are happily clicking “Allow” like it’s a goddamn dopamine button. Bravo!

So what happens when you give these pricks the keys? They hijack your accounts, pull in sensitive emails, swipe contact lists, and basically make a mess of your digital life. All without a single password stolen, mind you — just your oh-so-generous “consent.” It’s phishing 2.0: now with less effort and more chaos!

Apparently, this ConsentFix trash uses compromised or malicious apps registered in Azure to pull off the con, tricking Microsoft 365 or Entra ID users into granting them permissions straight into the corporate cookie jar. Once they’ve got access, it’s data exfil, spam campaigns, and all the cyberbullshit you’d expect. Researchers found that attackers are mainly targeting business accounts, because why bother stealing from broke individuals when you can siphon corporate gold?

The defense? The same boring crap you’ve heard a thousand times — verify what the hell you’re granting permissions to, restrict who can authorize third-party apps, and monitor your tenant like you actually give a damn. The moral of the story? Don’t click shit you don’t understand, because somewhere, some smug hacker is already naming their yacht after your stupidity.
