Business Email Compromise: Real Attack Patterns Affecting Suffolk Businesses

Business Email Compromise (BEC) is one of the most financially damaging forms of cyber crime affecting UK businesses today. While large enterprises often make the headlines, small and medium-sized businesses across Suffolk are increasingly in the firing line. These attacks are not random or opportunistic. They are carefully planned, highly convincing, and designed to exploit trust, urgency, and everyday business processes.

What makes BEC particularly dangerous is that it often bypasses traditional cyber defences. There is no obvious malware, no suspicious links, and no warning signs that immediately raise alarm. Instead, attackers rely on social engineering, research, and timing, which is why even well-run businesses can fall victim.

Common Business Email Compromise attack patterns we’re seeing in Suffolk

Through our work with local businesses in Ipswich, Felixstowe, Woodbridge and across Suffolk, we are seeing several recurring BEC techniques being used successfully against Suffolk businesses.

CEO impersonation
In these attacks, fraudsters send emails that appear to come from a senior leader, director, or business owner. The message typically requests an urgent payment, often framed as confidential or time-sensitive. These emails are frequently sent late in the day, during busy periods, or when key decision-makers are known to be unavailable, increasing the likelihood that normal verification steps are skipped.

Fake invoice and supplier payment fraud
Attackers pose as trusted suppliers or partners and request that future payments be sent to new bank account details. In many cases, criminals have monitored email conversations for weeks, allowing them to replicate tone, formatting, and timing with alarming accuracy. A single successful payment can result in significant financial loss that is difficult to recover.

Compromised email accounts
Once attackers gain access to a legitimate email account, they can operate unnoticed for extended periods. Using real email addresses and existing message threads, they target colleagues, customers, or suppliers with convincing requests for payments or sensitive information. Because the emails come from a genuine account, they are far more likely to be trusted.

Why Business Email Compromise attacks work

BEC attacks succeed because they exploit normal business behaviour rather than technical weaknesses alone. Common factors include:

• Trust in internal emails and familiar sender names
• Pressure to act quickly on urgent or confidential requests
• Lack of formal verification processes for payment changes
• Over-reliance on basic email filtering and spam controls

Importantly, falling victim to a BEC attack is not a sign of negligence. These attacks are designed to look legitimate and to catch people during moments of distraction or pressure.

Early warning signs your business should watch for

While BEC attacks are subtle, there are warning signs that employees should be trained to recognise:

• Requests to change bank details without prior notice or confirmation
• Unusual urgency, secrecy, or pressure to act immediately
• Requests that bypass established approval or finance processes
• Subtle changes in email tone, language, or formatting
• Instructions not to verify the request with others

Encouraging staff to question and verify unusual requests is one of the most effective defences.

How to reduce the risk of Business Email Compromise

Protecting your business from BEC requires a balanced approach that combines technology, people, and process.

Technology
Advanced email security can help detect impersonation attempts and suspicious behaviour. Multi-factor authentication (MFA) significantly reduces the risk of account compromise by preventing unauthorised access, even if login details are stolen.

People
Regular staff awareness training ensures employees understand how BEC attacks work and feel confident challenging unusual requests. Creating a culture where verification is encouraged, not criticised, is critical.

Process
Clear procedures for payment approvals, bank detail changes, and escalation routes help remove ambiguity during high-pressure situations. Simple steps, such as mandatory call-backs for payment changes, can prevent substantial losses.
