4 min. read

Learning about business email compromise (BEC) through real-life examples is crucial because it highlights cybercriminals' tactics and techniques, helping individuals and organizations better understand the risks.

Examples show the diversity of BEC schemes, from fake invoices to executive impersonation, and illustrate the devastating financial, operational, and reputational impacts these scams can have. By studying actual incidents, organizations can identify red flags, recognize patterns in fraudulent behavior, and implement more effective security measures to prevent falling victim to similar attacks.

How Do BEC Scams Work?

Business email compromise (BEC) scams typically involve cybercriminals who impersonate a trusted individual or organization, such as a company executive or business partner, to deceive victims into taking harmful actions. The attacker may spoof a legitimate email address or hack into an actual account, then request wire transfers, invoice payments, or access to sensitive information.

The goal is to trick the recipient into transferring funds or sharing confidential data without realizing the fraudulent request. These scams often rely on social engineering tactics, exploiting human trust and urgency to execute the scheme.

Common Tactics Used in BEC Attacks

Business email compromise attacks are increasingly sophisticated. They often employ an array of common tactics to deceive even the most vigilant organizations.

Social Engineering

Social engineering techniques are a staple method, wherein attackers manipulate individuals into divulging confidential information or performing actions compromising security. By masquerading as trusted partners or high-level executives, these attackers can exploit the natural tendency to comply with authority figures or meet urgent demands.

Phishing and Spoofed Emails

Phishing and spoofed emails are also prevalent tactics. These emails leverage realistic-looking email addresses and layouts to convince recipients of their authenticity. These emails often request sensitive information or prompt users to click on malicious links, leading to devastating breaches.

Fake Invoice Requests

Another common maneuver involves fake invoice requests, where cybercriminals send invoices that appear legitimate, prompting businesses to transfer funds to fraudulent accounts inadvertently.

Cybercriminals often exploit businesses’ reliance on digital transactions by crafting fake invoice requests to initiate BEC attacks. These fraudulent invoices usually mimic those from legitimate suppliers with whom the company frequently conducts business, using familiar logos and subtly altered sender email addresses to avoid detection.

These tactics are designed to subtly infiltrate and capitalize on the trust typically granted in business communications, making it crucial for companies to remain vigilant against such threats.

CEO Fraud

CEO fraud is a type of BEC scam where cybercriminals impersonate a company's CEO or another high-ranking executive to trick employees, typically those in finance or HR, into transferring funds or sharing sensitive information.

The attacker usually creates a sense of urgency, making the request seem legitimate and time-sensitive. These emails may appear to come from the CEO's real email address or a convincing spoofed version, leading the employee to comply without questioning the request. CEO fraud can result in significant financial losses and compromise sensitive company data.

Account Compromise

Account compromise is a type of cyberattack in which a malicious actor gains unauthorized access to an individual’s or organization’s email, online account, or system credentials. Once the account is compromised, the attacker can use it to conduct fraudulent activities, such as sending phishing emails to contacts, requesting unauthorized payments, or stealing sensitive information.

In the context of BEC, a compromised email account may be used to send legitimate-looking messages from within the organization, making it easier to deceive recipients into transferring funds or sharing confidential data.

False Invoice Scheme

A false invoice scheme is a BEC scam where cybercriminals send fraudulent invoices to companies, pretending to be legitimate vendors or suppliers. The attackers usually impersonate a trusted third party or an internal employee who typically handles payments, requesting payment for goods or services that were never provided.

The fraudulent invoice is often designed to look authentic, with accurate company logos and information. Victims, believing the invoice to be legitimate, process the payment directly to the attacker’s account instead of the actual vendor.

Attorney Impersonation

Attorney impersonation is a business email compromise scam where cybercriminals pose as legal professionals, such as attorneys or legal representatives, to deceive victims into taking specific actions.

In these schemes, the attacker may impersonate a known attorney or law firm, often contacting employees or executives under the guise of handling urgent legal matters, real estate transactions, or confidential business dealings.

The impersonator creates a sense of urgency or confidentiality, pressuring the recipient to transfer funds, share sensitive information, or approve payments without thorough verification. These scams exploit trust in legal professionals and can lead to substantial financial loss or the compromise of sensitive data.

Data Theft

In BEC, data theft may occur when attackers gain access to email accounts or corporate systems to steal sensitive data or confidential information. The stolen data can be used for identity theft, further cyberattacks, or sold on the black market, causing significant harm to individuals and businesses.

Supplier Swindle

A supplier swindle is a BEC scam where cybercriminals impersonate a trusted supplier or vendor to deceive an organization into making fraudulent payments. The attacker typically gains access to or spoofs the supplier’s email account and sends an invoice or payment request to the victim company, often claiming a change in banking details.

Believing the request is legitimate, the company unknowingly transfers funds to the attacker’s account instead of the real supplier. This scam can lead to significant financial loss, strained business relationships, and disruptions in supply chain operations.

Notable Examples of BEC Attacks

BEC attacks are gaining notoriety for their complexity and the substantial financial losses they cause. Below are some real-world BEC attacks along with a comprehensive overview of their methodologies, the intricacies of their execution, and the profound impact they had on their victims. Through these examples, organizations can further recognize the patterns and tactics employed by cybercriminals in BEC schemes.

Tech Giants Duped in $121 Million BEC Scam

A high-profile BEC attack provides a compelling example of how these scams can unfold unnoticed. In this case, the attacker tricked two major tech companies into wiring approximately $121 million to bank accounts under his control.

The cybercriminal impersonated a legitimate hardware vendor by forging email addresses, invoices, and corporate seals. Over two years, the attacker convinced the companies’ accounting departments to authorize large wire transfers for non-existent goods and services.

The scam succeeded due to the convincing nature of the forged documents and the assumption that communications from what appeared to be a trusted vendor were legitimate.

Major Automaker Falls Victim to a False Invoice Scam

A sophisticated false invoice fraud was observed when fraudulent individuals scammed a major automobile manufacturing company. This led to an illegal transfer of $37 million to a fake account. The fraudsters posed as genuine business partners and created convincing emails, which they sent to the finance and accounting departments of the automobile brand subsidiary.

These communications requested the redirection of funds to a bank account, which was covertly under the fraudsters' control. Regrettably, the company's security professionals realized the scam post-transfer, rendering any attempt to halt the transaction futile.

Atlanta Scammer: $250,000+ Fraud

In 2020, an Atlanta-based scammer orchestrated a sophisticated business email compromise scheme that resulted in fraud exceeding $250,000. This individual was adept at creating fake business personas and utilized deceptive email communication to pose as a trusted vendor.

By infiltrating the email system of a reputable company, the scammer intercepted legitimate financial transactions. Taking these opportunities, the fraudster subtly altered bank account details in the invoices, redirecting substantial sums of money to untraceable accounts under their control.

Victims of this scheme included both large corporations and smaller businesses, highlighting the pervasive nature of such scams. The incident underscores the critical need for businesses to implement resilient email verification processes and constantly educate employees about the evolving tactics employed in BEC attacks.

Homeless Charity: $625,000 Loss

In a devastating example of BEC, a homeless charity fell victim to a $625,000 fraud, significantly impacting its ability to support those in need. This scam was executed through meticulous social engineering tactics, where cybercriminals impersonated trusted vendors and persuaded the charity's finance team to divert funds into their fraudulent accounts.

Despite efforts to mitigate the loss, the attack had severe repercussions, leading to budget constraints and reduced resources for various charitable programs. The incident also underscored the vulnerability of non-profit organizations to sophisticated cyberthreats, highlighting the critical need for stronger cybersecurity measures.

This case serves as a cautionary tale, emphasizing the importance of verifying all financial transactions and enhancing employee awareness to safeguard against similar scams.

Recognizing BEC Threats

Recognizing business email compromise threats in the ever-evolving cybersecurity landscape is crucial for safeguarding an organization's assets.

Red Flags in Emails

One pivotal aspect of BEC recognition is identifying red flags in emails. Suspicious characteristics, such as unexpected attachments, urgent requests for secrecy, or slight alterations in familiar email addresses, can often be warning signs of malicious intent.

Unusual Payment Requests

Another common trait to watch out for involves unusual payment requests that deviate from typical company procedures, especially those insisting on immediate funds transfer to accounts different from those usually used.

Monitoring Vendor Account Changes

Monitoring changes in vendor account details also proves vital, as cybercriminals often exploit such updates to redirect financial transactions. Moreover, organizations should emphasize the importance of verifying significant alterations or requests through phone calls or face-to-face confirmations when possible.

Real-World Impact of BEC

Business email compromise has profound real-world implications, affecting organizations worldwide. Financial losses attributed to BEC attacks have surged dramatically, with estimates reaching billions annually.

The FBI Internet Crime Complaint Center (IC3) identified nearly $51 billion in exposed losses from BEC attacks between 2013 and 2022. In 2022 alone, the FBI’s Recovery Asset Team initiated action on 2,838 BEC complaints involving domestic transactions with potential losses exceeding $590 million.

This surge in BEC attacks is partly due to phishing-as-a-service platforms such as BulletProftLink, which provides end-to-end services for creating malicious email campaigns. These services make BEC operations more accessible to attackers​. In particular, attackers' growing use of automation, sophisticated social engineering, artificial intelligence (AI), and machine learning (ML) continues to create substantial cybersecurity challenges for organizations of all sizes.

These attacks can cripple businesses, particularly small to medium-sized enterprises, that may lack the resources to recover quickly from such significant setbacks. Furthermore, the damage extends beyond immediate financial harm; the long-term impact on brand reputation can be detrimental.

Customers and partners may lose trust in a company that falls victim to a BEC attack, leading to decreased business opportunities and potential partnerships. This erosion of trust compounds the financial impact and can necessitate extensive public relations efforts to rebuild the brand's image.

Additionally, companies must often allocate substantial resources to investigate and mitigate the effects of these compromises, diverting attention from their core business operations.

Best Practices for Mitigation

The pervasive threat of BEC requires businesses to adopt a proactive and multi-layered approach to cybersecurity.

Continuous Monitoring

Continuous monitoring and adaptation are crucial in identifying potential threats before they can cause significant harm. Companies must stay informed about the latest BEC tactics and adjust their defenses accordingly.

Organizations should implement real-time email tracking to detect anomalies and suspicious activities quickly. Using advanced tools to identify BEC patterns enables rapid responses to threats. Regularly updating security protocols and adapting to the latest trends ensures businesses stay ahead of cybercriminals, allowing proactive risk mitigation and preventing financial or reputational damage.

Collaboration with cybersecurity experts can provide invaluable insights and resources, further strengthening a company’s ability to prevent such attacks. These professionals bring a wealth of knowledge and experience in identifying potential vulnerabilities within an organization's email infrastructure and can provide tailored solutions to mitigate risks.
