Business Email Compromise Response and Prevention

Business email compromise can lead to financial fraud, information exposure, credential theft or access to connected systems. Effective response requires coordinated leadership, communications and technical action.

A coordinated response matters

BEC is more than an email problem

Business email compromise can begin with a deceptive message or misuse of a trusted digital identity, then develop into payment fraud, unauthorized disclosure, credential theft or access to connected systems. A successful response therefore needs business and technical teams working from the same facts and under clear incident leadership.

01

Establish control

Assign an Incident Lead, use trusted communication channels and engage the right business, legal, insurance and operational stakeholders.

02

Contain and investigate

Secure the identity, revoke access, remove persistence, preserve evidence and determine whether the compromise reached other systems or people.

03

Respond to confirmed impact

Follow every applicable response path for fraudulent messages, financial activity, exposed information, connected systems and affected third parties.

04

Recover and strengthen

Verify the account and endpoint, restore access carefully, monitor for recurrence and turn confirmed findings into practical control improvements.

This overview is general guidance. Incident response should be adapted to the organization’s environment, contractual commitments, applicable laws, legal counsel and cyber-risk insurance requirements.
Impact response workflow

One incident. Multiple response paths.

Confirmed impacts may activate more than one response path at the same time. Communication and reporting continue from activation through recovery and closure.

Supporting response workflows

Communication and technical response run in parallel

Once the impact is understood, communication and technical response continue as coordinated workstreams. The communication path controls internal and external messaging, while the technical path contains, investigates, remediates and validates the environment.

Turn the incident into stronger controls

The post-incident review should address both the technical compromise and the business process that allowed a fraudulent request to succeed. Priorities may include stronger identity controls, email protection, independent transaction verification, endpoint detection, employee awareness, partner procedures and reducing unnecessary access.
