What is business email compromise?
Business Email Compromise (BEC) is a targeted form of cyber fraud in which attackers compromise or impersonate trusted email accounts to deceive employees, customers or suppliers into transferring money, changing payment details or disclosing sensitive information.
Attackers may gain access to a genuine mailbox through stolen credentials or phishing, or impersonate an organisation using spoofed or lookalike domains. Once access is gained, criminals may monitor conversations and wait for the right opportunity to manipulate an invoice, payment request or sensitive exchange.

How our Business Email Compromise response works
When a Business Email Compromise (BEC) incident strikes, a structured and expert-led response is essential. At Integrity360, we follow a clear, effective process to investigate, contain, and resolve the threat—while helping you recover quickly and reduce the risk of recurrence.
Step 1 – Emergency triage and account security
As soon as we’re engaged, Integrity360’s Incident Response team initiates same-day triage. We assign a dedicated response lead, initiate stakeholder communications, agree reporting lines and call schedules, and begin immediate information gathering. Our priority is to understand the scope of the compromise, stabilise the environment, and launch the initial response plan.
Step 2 – BEC investigation and digital forensics
Our Digital Forensics and Incident Response (DFIR) specialists conduct a detailed analysis of the breach. This includes identifying the attacker’s point of entry, methods used to impersonate individuals or access sensitive data, signs of persistence, fraud exposure, and potential regulatory implications. Our findings form the foundation of a tailored mitigation strategy.
Step 3 – Containment and mitigation
We act swiftly to contain the threat, removing any footholds the attacker has established. This includes revoking unauthorised access, isolating affected accounts or systems, and implementing technical controls to prevent further compromise. We also apply best practice security hardening measures across your Microsoft 365 or cloud environment to reduce future risk.
Step 4 – Credential and identity remediation
Once the threat is fully contained, we move to remediation. This involves eradicating the root cause of the attack, restoring affected services, and supporting secure password resets and Mult Factor Authentication (MFA) enforcement. We work closely with your teams to restore trust in communications and re-establish a clean operational state.
Step 5 – Financial and data-loss assessment
Using advanced tooling and expert-led investigation, we assess the extent of any data loss, identify compromised communications, and evaluate the risk to personal or regulated information. If required, we help you meet GDPR or other regulatory obligations, supporting any breach reporting requirements with clear documentation and expert advice.
Step 6 – Post-incident review and resilience improvement
After recovery, we conduct a comprehensive post-incident review. This includes lessons learned, risk assessments, and recommendations for improving your email security, user awareness, and response capabilities. We provide a detailed incident report and advise on longer-term protection strategies, including managed detection and response (MDR) and cyber awareness training.
Why Choose Integrity360 for BEC Response?
Business Email Compromise can quickly become both a cybersecurity and financial crisis. Responding effectively requires more than simply resetting a password. Organisations need to understand how the attacker gained access, what they were able to see or change, whether other accounts are affected and whether fraudulent activity is still ongoing.
Integrity360 combines Incident Response, Digital Forensics, threat intelligence and cloud security expertise to help organisations investigate, contain and recover from BEC incidents.
24/7 Incident Response Support
BEC attacks do not follow business hours. Integrity360 provides 24/7 Incident Response support, giving organisations access to experienced specialists when suspicious activity or an active compromise requires immediate investigation.
Digital Forensics and BEC Investigation
Our Digital Forensics and Incident Response specialists investigate compromised accounts, authentication activity, malicious email rules, suspicious communications and other evidence to establish how the attack occurred and determine its full scope.
Identity and Cloud Security Expertise
BEC attacks increasingly target identities and cloud-based email environments rather than traditional endpoints. Integrity360 combines Incident Response expertise with extensive knowledge of identity, Microsoft and cloud security to investigate account compromise and help prevent continued attacker access.
NCSC Assured Cyber Incident Response
Integrity360 is an assured provider under the National Cyber Security Centre's Cyber Incident Response scheme, providing organisations with additional confidence in the capabilities, processes and expertise supporting their response.
From containment through to recovery

Types of Business Email Compromise we investigate
Compromised email accounts
Attackers gain access to a legitimate mailbox and use it to monitor communications, impersonate the account owner or send fraudulent messages.
Invoice and payment fraud
Attackers intercept or impersonate supplier communications and attempt to redirect legitimate payments to criminal-controlled bank accounts.
Executive impersonation
Criminals impersonate senior executives or other trusted individuals to pressure employees into making urgent payments or disclosing information.
Supplier and vendor impersonation
Attackers pose as trusted suppliers and request changes to banking details, invoices or payment processes.
Payroll and HR fraud
BEC attacks may target payroll or HR teams with requests to change employee bank details or disclose personal information.
Data theft
Not every BEC attack is focused on money. Compromised email accounts can expose sensitive correspondence, commercial information, personal data and credentials.
Business Email Compromise Incident Response FAQs
What is Business Email Compromise?
Business Email Compromise (BEC) is a targeted form of cyber fraud in which attackers compromise or impersonate a trusted email account to deceive employees, customers or suppliers. The objective is often to redirect payments, change banking details or obtain sensitive information. Attackers may use stolen credentials to access a genuine mailbox or impersonate a trusted individual or organisation without directly compromising their account.

What is the difference between business email compromise and phishing?
While both involve deception via email, phishing typically casts a wide net, sending mass emails with malicious links or attachments. Business Email Compromise (BEC), on the other hand, is highly targeted. Attackers often impersonate trusted individuals to trick employees into making payments or revealing sensitive information. BEC is usually more sophisticated and financially motivated.
How do cybercriminals gain access to business email accounts?
Attackers use several methods, including phishing emails, credential stuffing, or exploiting weak passwords and lack of multi-factor authentication (MFA). Once inside a mailbox, they may observe communications for weeks before launching a carefully timed attack, such as intercepting an invoice or issuing fraudulent payment instructions.
Who is most at risk of a business email compromise attack?
BEC attacks often target finance departments, executives, HR teams, and accounts payable staff, anyone who has authority over financial transactions or access to sensitive business information. SMEs and large enterprises alike are at risk, especially those with weak email security or limited employee awareness training.
How can I tell if our business has been targeted by a BEC attack?
Warning signs include:
-
Unexpected requests for urgent wire transfers or changes to payment details
-
Messages with slight spelling variations in email addresses or domains
-
Unusual communication patterns, such as requests outside business hours
-
Pressure to bypass standard payment or approval processes
If you notice any of these signs, contact Integrity360 immediately for investigation and response.
What should I do if we fall victim to a BEC scam?
-
Stop the transaction if it hasn’t been completed.
-
Notify your bank to initiate a recall of the funds.
-
Report the incident to your IT and security teams immediately.
-
Engage Integrity360’s Incident Response Team to contain and investigate the breach.
-
Review and strengthen your email security and internal controls to prevent future attacks.
How quickly should you respond to a BEC attack?
You should respond to a suspected Business Email Compromise immediately. Attackers may still have access to compromised accounts, be monitoring communications or attempting additional fraudulent transactions. Rapid action can help secure affected identities, preserve forensic evidence, identify the extent of the compromise and prevent further financial or data loss. If money has been transferred fraudulently, your financial institution should also be contacted immediately.
Can a BEC attack happen without malware?
Yes. Business Email Compromise does not require malware. Attackers can use phishing, stolen credentials, session theft, impersonation or social engineering to gain access to email accounts or convince employees to take fraudulent actions. Some BEC attacks may not involve a compromised account at all, instead relying on spoofed or lookalike email addresses to impersonate a trusted individual, supplier or organisation.
What should I do if money has already been transferred?
If a fraudulent payment has already been made, contact your bank or payment provider immediately and provide details of the transaction. Acting quickly may improve the possibility of stopping or recalling the payment. You should also secure affected accounts, preserve relevant emails and other evidence, notify your security team and begin an investigation to determine how the fraud occurred and whether the attacker retains access to your environment.
Can Business Email Compromise cause a data breach?
Yes. Although BEC is often associated with financial fraud, a compromised email account may also expose personal, commercial or otherwise sensitive information. If attackers access or disclose protected data, the incident may constitute a data breach and could create regulatory or notification obligations. The investigation should establish what information was accessible and what evidence exists that it was viewed, downloaded, forwarded or otherwise exposed.
How long does a BEC investigation take?
The length of a BEC investigation depends on the scope and complexity of the incident. A compromise involving one recently affected mailbox may be investigated relatively quickly, while an incident involving multiple identities, extended attacker access, financial fraud or wider cloud activity can require a more extensive investigation. Initial containment and triage should begin immediately, with the investigation continuing until the extent and impact of the compromise are understood.
