Responding to Ransomware With Speed and Control

We support organisations at every stage of a ransomware incident—from initial detection and containment through to forensic investigation, recovery, and post-incident guidance—helping teams regain control and make informed decisions when it matters most.
Common Business Email Compromise Scenarios
BEC incidents do not always look the same. They can range from a single fraudulent payment request to a wider compromise of cloud email, identity systems, and internal processes.
Executive Impersonation
Attackers impersonate a CEO, CFO, or other senior leader to pressure staff into making urgent payments or disclosing sensitive information.
Supplier or Invoice Fraud
Email communications are manipulated to change bank account details, redirect invoices, or interfere with legitimate payment workflows.
Payroll Diversion
Threat actors pose as employees or compromise accounts to request payroll changes or redirect salary payments.
Mailbox Compromise
An attacker gains access to a legitimate mailbox, monitors conversations, and inserts fraudulent requests at the right moment.
Internal Fraud Enablement
Compromised email access is used to target finance, HR, legal, or procurement functions and exploit approval processes.
Data Exposure Through Email
Sensitive commercial, legal, employee, or client information may be accessed, forwarded, or exfiltrated during the compromise.

Frequently Asked Questions
What Is Business Email Compromise?
Business Email Compromise is a form of cyber-enabled fraud where attackers use email to impersonate trusted people or exploit legitimate accounts to manipulate payments, data sharing, or business processes.
Does BEC Always Involve a Hacked Mailbox?
No. Some incidents involve direct compromise of a mailbox or cloud identity account, while others rely on spoofed domains, lookalike addresses, or impersonation without full account compromise.
Can You Help if Funds Have Already Been Transferred?
Yes. Even where financial loss has already occurred, rapid investigation is important to support containment, evidence preservation, internal response, and next-step decision-making.
Can You Investigate Microsoft 365 Email Compromise?
Yes. Microsoft 365 environments are commonly involved in BEC matters, and investigation may include mailbox access, authentication activity, forwarding rules, and related identity indicators.
