Attackers now flood accounts with MFA requests until someone clicks approve. Bellwether IT owns the monitoring that stops this in Microsoft 365.

The Daily Risk in Your Bookkeeping Workflow

A bookkeeper opens Microsoft 365 to approve a vendor invoice. Seconds later another prompt appears on the phone. Then another. Good IT already watches sign in logs for this pattern and blocks the source before the third request lands.

When the same account receives repeated prompts during normal work, that is the attack known as prompt bombing. The goal is simple. Wear down the user until they tap approve and hand over the session.

What Good IT Already Monitors

Proper identity protection tracks every Microsoft 365 login attempt across the tenant. It flags repeated MFA requests from the same user in a short window. It also checks for logins that follow an employee laptop leaving the building without being wiped.

  • Repeated MFA pushes on one account during invoice processing
  • Sign ins from new devices right after hardware changes hands
  • Approval clicks that occur outside normal office hours

These checks run in the background. The office team never sees the blocked attempts.

The Tell That Your Provider Is Not Handling It

Your staff starts complaining about constant MFA fatigue. The bookkeeper mentions ignoring prompts just to finish the invoice. No one from your IT company has reviewed sign in logs in months. Those are clear signs the protection layer is missing.

How Bellwether Addresses Identity Attacks

We review Microsoft 365 sign in activity daily and adjust conditional access rules when patterns appear. We also confirm that former employee devices lose access the same day hardware is returned.

What we do Bellwether monitors Microsoft 365 authentication logs and enforces policies that block repeated MFA attempts before they reach your team.
