Key Takeaways
- Passwords aren’t the only risk: Criminals can exploit device codes to gain access without stealing credentials.
- Traditional safeguards can fail: MFA alone may not block this kind of attack.
- Business impact is serious: Attackers can read, steal, and impersonate directly from your Microsoft account.
- Awareness is critical: Employees need to recognize that entering a code can be just as risky as typing in a password.
When you think about online security, the first thing that probably comes to mind is protecting your password. But what if we told you that attackers don’t even need your password to get into your Microsoft account?
That’s the reality businesses are facing today. A new wave of cyberattacks is exploiting legitimate Microsoft login pages—and even bypassing multi-factor authentication (MFA). At NSI, we want you to be aware of this evolving threat so you can better safeguard your organization.
What’s Happening?
The scheme is called device code phishing, and it’s gaining traction fast. Unlike classic phishing—which tricks you into typing your username and password into a fake site—this technique manipulates you into granting access yourself.
Here’s how it works:
- You receive an email that looks authentic (maybe from “HR” or a colleague), inviting you to a Microsoft Teams meeting or prompting you to log in.
- The link directs you to a real Microsoft login page, so nothing feels suspicious.
- Instead of asking for your password, you’re asked to enter a short “device code” included in the email.
- By entering that code, you’re not logging yourself in—you’re logging the attacker in on their device.
The danger? Once authorized, the attacker can read emails, open files, and impersonate you to trick others in your company. And because the login goes through Microsoft’s official system, even MFA may not stop them.
Why This Attack Is So Effective
This type of scam is particularly dangerous for businesses because:
- It looks legitimate – You’re using an official Microsoft site, not a sketchy imitation.
- It bypasses traditional defenses – No fake login page means anti-phishing tools may not trigger.
- It sidesteps MFA – Even advanced security setups aren’t guaranteed protection.
Think of it as unknowingly handing over your office key to a stranger—and watching them walk in like they belong there.

FAQs
If the login page is real, how can I spot the scam?
The red flag is the device code. If you’re asked to enter a code sent by email, verify the request through official channels before typing anything in.
Does MFA protect me from this?
Unfortunately, not always. Device code phishing can bypass MFA because the login is happening on the attacker’s device.
What should I do if I think I’ve entered a device code?
Contact your IT provider or NSI immediately. We can revoke unauthorized access and secure your account.
