Hackers Pull the Same Old Phishing Shit, This Time with Fake Microsoft Entra Passkey Enrollment

Right, so here’s the latest steaming pile of cybercrime nonsense: attackers are pretending to be Microsoft Entra and tricking poor bastards into enrolling a fake passkey, which then hands over access to Microsoft 365 accounts. Because apparently usernames, passwords, MFA fatigue, and every other security nightmare weren’t enough, now we’ve got scumbags abusing passkey workflows too.

The basic con is painfully predictable. The victim gets lured into what looks like a legitimate Microsoft security or account workflow, usually dressed up to seem urgent, important, and just corporate enough that some overworked employee clicks the damned thing without thinking. Instead of completing a real enrollment, they end up authorizing a fraudulent passkey setup controlled by the attackers. Once that happens, the criminals can waltz into the Microsoft 365 environment like they own the bloody place.

What makes this especially nasty is that passkeys are supposed to be one of the shiny “more secure” authentication methods. And they are—when they’re implemented properly and when users aren’t being socially engineered into doing something catastrophically stupid. But as usual, the weak point in the system is the human at the keyboard, cheerfully clicking through prompts because the screen said “Microsoft” on it and nobody reads a damn thing anymore.

According to the report, the attackers are leveraging phishing infrastructure and fake login or enrollment pages to capture or manipulate authentication flows. The whole point is to get a victim to bind authentication to something the attacker can use, bypassing the confidence people normally have in passwordless sign-ins. It’s the same old story: take a legitimate security feature, wrap it in deception, and weaponize user trust. Elegant in a deeply irritating, criminal sort of way.

The end result is exactly the sort of mess you’d expect. Once inside a Microsoft 365 account, the attackers can rummage through email, impersonate users, pivot deeper into the organization, and generally turn the tenant into a flaming heap of compliance violations and incident response meetings. If they land in an account with privileges, then congratulations, the shitshow gets even worse.

The lesson, which nobody will properly learn because that would be too convenient, is that “passwordless” does not mean “phishing-proof by magic.” Organizations need to lock down enrollment processes, monitor suspicious authentication events, train users to recognize fake enrollment prompts, and verify exactly how passkeys are being introduced into their environment. If your staff can be duped into registering an attacker-controlled credential, then your lovely modern identity stack is about as useful as a chocolate bloody firewall.

Admins should be watching for unusual device registrations, unexpected changes to authentication methods, strange sign-in patterns, and any indication that users are being redirected to dodgy lookalike pages. If you’re not auditing this stuff, then you’re basically leaving the door open with a big sign saying, “Come on in and nick our cloud data, you absolute parasites.”

So yes, yet again, attackers are succeeding not because the tech is mystical and unstoppable, but because social engineering still works frighteningly well on busy, distracted humans. Same circus, same clowns, newer branding.

Anecdote from the trenches: years ago, I watched a user type their password into a popup that literally looked like it had been designed by a drunk raccoon with PowerPoint, then swear blind it was legitimate because “it had the company logo.” That, in a nutshell, is why we can’t have nice things.
