About BEC Response
Business Email Compromise (BEC) is one of the fastest-growing and most financially damaging cyber threats affecting organisations today, costing businesses billions annually and often bypassing traditional security measures. These attacks exploit human trust, using tactics such as email spoofing, account takeover, and carefully crafted social engineering to trick employees into transferring funds, changing payment details, or disclosing sensitive data.
When every minute counts, our expert responders are ready 24/7 to contain the breach, trace unauthorised activity, work with financial institutions and law enforcement where appropriate, and guide you through a secure recovery process. We combine advanced forensic techniques with clear, actionable advice, ensuring you not only recover quickly but also strengthen your defences to prevent future attacks.
Common signs of business email compromise
- Urgent requests to send money or transfer funds
- Emails that mimic legitimate correspondence but come from a spoofed email domain
- Requests for changes to payment instructions from suppliers
- Pressure to act quickly without verbal confirmation
- Emails containing malicious links, suspicious attachments, or strange phrasing

Who's at risk?
From finance teams to entry-level employees, any individual within a business can be targeted. Business Email Compromise (BEC) is designed to trick employees into taking actions that benefit attackers, such as granting access to systems, updating payment instructions, or responding to fraudulent emails from what appears to be a financial authority.
Attackers may spoof your company website, impersonate trusted vendors, or use insights from previous breaches to launch highly convincing scams. Even businesses with user awareness training are vulnerable, as BEC tactics, like domain spoofing and social engineering, are increasingly sophisticated.
Ultimately, any organisation that communicates with suppliers, handles financial transactions, or interacts with a financial institution can be at risk of BEC attacks.

Frequently asked questions
Key information when you’re under pressure.
Business Email Compromise (BEC) is a type of cyber attack that targets a company's employees by exploiting trust through deceptive communications. BEC involves the use of legitimate-looking emails, or sometimes a text message, to trick employees into revealing sensitive information, changing payment instructions, or transferring money. Unlike standard phishing emails, which often contain obvious red flags, BEC attacks rely on subtle, highly personalised social engineering tactics. With access gained through phishing or account compromise, BEC scammers can convincingly impersonate executives, suppliers, or colleagues. These attacks are difficult to detect and often result in organisations falling victim to significant financial losses or data breaches.
Signs of a Business Email Compromise (BEC) incident include:
Unusual or urgent requests for payments, including urgent wire transfers, or divulging sensitive information
A compromised email account sending unexpected or unauthorised messages
Changes in communication patterns or payment instructions that seem out of character
Domain spoofing or emails from similar-looking addresses designed to deceive
Unexpected changes to inbox rules, email forwarding settings, or multi-factor authentication (MFA) prompts
Yes. Beyond response and recovery, Zensec offers email security assessments, identity protection solutions, multi-factor authentication (MFA) implementation, and security posture reviews. We also provide training to raise user awareness and strengthen your defenses against phishing campaigns and account takeover.
Phishing emails are typically broad, generic attacks aimed at tricking users into clicking malicious links or divulging sensitive data. These attacks are usually part of large-scale phishing campaigns with little personalisation.
Business Email Compromise (BEC), on the other hand, involves highly targeted and sophisticated attacks. BEC emails often mimic legitimate correspondence and are crafted to look like they're coming from trusted individuals such as a CEO, vendor, or member of the finance team. The goal is to gain account control, manipulate employees, and initiate email account compromise, often leading to compromised accounts, unauthorised wire transfers, or leaking of confidential information. Unlike phishing, BEC relies heavily on social engineering and deep familiarity with your business processes.
