BEC Fraud

A Guide to Business Email Compromise Fraud

As an intricate web of cyber threats continues to loom over modern businesses, one particularly cunning adversary has emerged: Business Email Compromise (BEC) fraud. With its sophisticated tactics and devastating consequences, BEC fraud has become a significant concern for organisations of all sizes, across industries worldwide. In this blog, we delve into the depths of BEC fraud, exploring its modus operandi, impact and the measures your business can take to mitigate this pervasive threat.

Understanding BEC fraud

At its core, BEC fraud involves cybercriminals infiltrating business email accounts to conduct unauthorised transactions or extract sensitive information. Unlike traditional phishing attacks, which cast a wide net in the hope of hooking unsuspecting victims, BEC fraud is highly targeted. Perpetrators impersonate trusted entities like CEOs or vendors and manipulate employees, particularly those in finance or accounts departments, into transferring funds or divulging confidential data.
In 2021, there were close to 5,000 reported BEC attacks on UK businesses, amounting to a staggering near £140m in financial losses.

The anatomy of a BEC scheme

BEC schemes come in various forms, each tailored to exploit specific vulnerabilities within your business. Common strains of this particular cyber-crime include:
  • CEO fraud

Hackers masquerade as high-level executives and email fraudulent requests to colleagues requesting money transfers or confidential data. A spoofed email address is used, often marked ‘Urgent’ to add additional pressure and the email is full of persuasive language. The fake email is then sent to a recipient like a finance director or manager in the hope of deceiving them into complying with their demands.
  • Invoice fraud

Invoice fraud involves manipulated invoices to deceive members of staff into redirecting payments to fraudulent accounts owned by criminals. Perpetrators typically gain unauthorised access to finance department’ email accounts, allowing them to intercept legitimate invoices or to create counterfeit ones. They then alter the payment details, such as bank account information or payment instructions, to fraudulently divert funds to their controlled accounts.
This deception often goes undetected, as the fake invoices appear convincing and are sent from compromised or spoofed email addresses.
  • Account compromise

Through phishing attacks or malware infiltration, hackers gain unauthorised access to employee email accounts. With control over these accounts, they monitor communications, gather intelligence and orchestrate fraudulent activities, whilst remaining undetected.
  • Lawyer fraud

BEC lawyer fraud is a sophisticated variation where cybercriminals impersonate lawyers or legal representatives to manipulate victims into transferring funds or disclosing sensitive information.

The toll of BEC fraud

The ramifications of falling victim to BEC fraud can be severe and far-reaching. Beyond the immediate financial losses incurred from unauthorised transactions, businesses may suffer reputational damage, legal liabilities and operational disruptions. Any loss of sensitive data can also expose your business to regulatory penalties and compromise the trust of your customers.

Safeguarding against BEC fraud

To mitigate the risk of BEC fraud, businesses need to adopt a multi-faceted approach that combines technological solutions, robust policies and employee education. Key measures include:
  • Email authentication

Implement email authentication protocols like DMARC (Domain-based Message Authentication, Reporting, and Conformance) that can help verify the legitimacy of incoming messages and detect spoofed domains.
  • Authorisation procedures

Establish clear protocols for verifying and authorising financial transactions, particularly those involving large sums or unfamiliar recipients. Implement dual authorisation and verification processes to add an extra layer of security.
  • Employee training

Educate staff members about the tactics used in BEC schemes and provide regular training on cybersecurity best practices, including how to identify phishing attempts, recognise suspicious behaviour and report potential threats promptly.
  • Enhanced monitoring

Deploy advanced cybersecurity tools capable of monitoring email traffic, detecting anomalies and flagging potentially fraudulent activities in real-time. Additionally, conduct regular audits and risk assessments to identify your business’s specific vulnerabilities and shore up its defences.
As businesses continue to navigate an increasingly digital landscape, the threat of BEC fraud cannot be underestimated. By understanding the tactics employed by cybercriminals, implementing robust security measures and fostering a culture of vigilance amongst employees, your business can fortify its defences and safeguard against the insidious threat of BEC fraud.
In an era where cyber resilience is paramount, staying one step ahead of malicious fraudsters is not just a goal but a necessity for the survival and success of businesses everywhere.
