Business Email Compromise & Cyber Fraud Investigation
Investigation and response for business email compromise, invoice fraud, vendor impersonation, account takeover, and payment-redirection incidents.

When a business email account is compromised or a criminal inserts fraudulent banking instructions into a legitimate invoice conversation, the first questions are urgent: Was an account actually hacked? Which mailbox or organization was compromised? What did the attacker access? Were messages forwarded or hidden? Is the account still exposed? WNC IT Pro helps Western North Carolina businesses investigate available technical evidence, contain affected accounts, secure Microsoft 365 environments, and reduce the chance of the same attack happening again.
Business email compromise (BEC) can involve a hacked Microsoft 365 account, vendor impersonation, invoice fraud, wire or ACH payment redirection, fraudulent banking-information changes, phishing, look-alike domains, malicious mailbox rules, external email forwarding, or an attacker silently monitoring an existing email conversation. The fraudulent message can look convincing because criminals may use real names, invoices, signatures, project details, and existing conversation history.
Our role is technical investigation, containment, remediation, and security improvement. We can review available account activity, sign-in information, mailbox rules, forwarding, authentication settings, suspicious messages, and other evidence available in the customer's environment. Where appropriate, we can help organize technical findings for coordination with the business's bank, attorney, cyber-insurance provider, or law enforcement. WNC IT Pro does not guarantee recovery of funds, promise definitive attribution, or represent its services as a substitute for law enforcement, legal counsel, a financial institution, or a specialized forensic laboratory when those services are required.
Who Needs Business Email Compromise & Cyber Fraud Investigation?
Businesses that discover altered invoice banking information, suspicious wire or ACH instructions, a hacked business email account, fraudulent messages sent from a legitimate mailbox, vendor impersonation, unexpected forwarding rules, suspicious Microsoft 365 sign-ins, or other signs of email-based financial fraud. The service is especially relevant to professional offices, law firms, healthcare organizations, contractors, property managers, financial workflows, and any business that sends or receives payment instructions by email.
Common Problems It Solves
- Banking information on a legitimate-looking invoice was changed without authorization
- A customer or vendor received fraudulent payment instructions from a business email conversation
- A Microsoft 365 or business email account appears to have been hacked
- Suspicious inbox rules, hidden rules, forwarding, or deleted messages appear in a mailbox
- Employees received unexpected MFA prompts, sign-in alerts, phishing messages, or password-reset activity
- A business needs to determine whether fraud came from its own account, the other party, spoofing, or a look-alike domain
- The immediate incident was contained, but the business needs stronger email, identity, MFA, and payment-verification controls
Why Professional Implementation Matters
Changing a password is important, but it may not answer how an email-fraud incident happened or whether unauthorized access persists. Microsoft documents suspicious forwarding, inbox manipulation rules, unusual sent or deleted mail, and authentication activity as indicators worth reviewing after account compromise. A structured response examines the available evidence, contains access, removes unauthorized persistence, documents what can be established, and then hardens the environment. Financial fraud also requires business-process controls: changes to payment instructions should be independently verified through a known contact method rather than trusted solely because they arrived in an existing email thread.
