Security action brief

Protect the account behind the payroll request.

Microsoft documented Storm-2755 targeting Canadian employees through malicious search results and advertising. Hijacked sign-in sessions were used to pursue payroll diversion, showing why a familiar inbox is not enough to verify a payment change.

What the source reports

Microsoft’s research describes attackers capturing authenticated sessions through fake Microsoft 365 sign-in experiences, then attempting payroll changes. The report recommends phishing-resistant authentication and provides investigation guidance. Some conventional MFA methods remain vulnerable to this kind of phishing.

What this means for your business

A compromised employee mailbox can make a fraudulent request look routine. Identity settings, mailbox rules, app permissions and independent payment verification all matter. Technical controls and a simple finance procedure should support each other.

Hands-on help from iGears Canada

Our Email & identity security setup turns the concern into an agreed set of tasks:

  • Review sign-ins, mailbox rules, app consent and account recovery settings.
  • Configure phishing-resistant authentication and access policies where supported.
  • Document independent verification of bank-detail changes and account recovery steps.

What you receive

An identity and mailbox findings list, agreed configuration changes and a practical verification and recovery guide.

How we keep the scope clear

Available controls depend on your Microsoft 365 or identity-provider licensing. We agree account access and changes in advance. Recovery of lost funds and full incident forensics are separate from a preventive configuration review.

Before the first conversation

Bring your email platform, approximate account count, administrator contact and how your finance or HR team currently verifies bank-detail changes.

We begin with your business priorities, the systems involved and who can authorize changes. You receive a scope and quotation before implementation begins.
