Common Types of BEC Attacks
Various strategies are employed in Business Email Compromise (BEC) attacks, all typically hinging on social engineering and identity fraud. According to the FBI, there are five principal categories of BEC scams that use basic techniques and limited tools to manipulate trust among company members.
Scammers frequently pose as credible individuals like CEOs or suppliers during these email compromise schemes, which makes thwarting BEC attacks a complex endeavor. To better safeguard against such threats, it’s crucial to explore the most common forms of BEC attacks and comprehend their mechanisms.
CEO Fraud
BEC scams commonly manifest as CEO fraud, in which cybercriminals mimic high-level executives to solicit urgent wire transfers from unwitting employees. These deceptive communications are crafted to seem as though they originate from the organization’s upper management, like the CEO or CFO. By leveraging an air of immediacy and authority, these requests coax employees into executing transactions hastily without proper authentication—a strategy that capitalizes on their tendency to conform promptly when seemingly directed by leadership.
The primary objective behind these schemes is often the redirection of funds into fake accounts held under criminal control. The perpetrators then use this misappropriated money either for direct financial gain or other nefarious activities.
Beyond siphoning off finances through fraud, such impostors may also aim at procuring confidential information by pretending to be trusted officials within a company. Predominantly targeting finance departments vulnerable to BEC exploits underscores an essential need for robust verification measures and educational initiatives designed specifically for preventing data theft incidents related to business email compromise (BEC) intrusions.
False Invoice Scheme
In a common BEC tactic known as the false invoice scheme, perpetrators masquerade as genuine vendors and send fabricated invoices that closely replicate authentic ones to businesses. These counterfeit bills are crafted with the intent of misleading companies into sending payments to illegitimate bank accounts. To ensnare organizations into executing fund transfers, attackers frequently forge plausible invoices supposedly issued by maintenance firms, internet service providers or various other utility vendors. These fraudulent documents often bear a striking resemblance to those from credible suppliers, which poses challenges for employees in identifying legitimate from deceptive demands.
Following an email account compromise, fraudsters might send fictitious invoices that stipulate remuneration be directed toward an alternate bank account or manipulate the existing account number slightly. Even though these alterations may appear insignificant, they effectively divert financial resources into coffers managed by cybercriminals. The consequences of such email account breaches can culminate in substantial monetary damages for both individuals and entities.
The sense of immediacy infused within these solicitations typically propels staff members to proceed hastily—often neglecting established authentication protocols—which amplifies their susceptibility to falling prey to successful BEC schemes.
Vendor Email Compromise
Phishing attacks via vendor email compromise occur when attackers pose as trusted vendors requesting payment for invoices—a strategy that is notably successful. This scam takes advantage of the confidence and longstanding connections that businesses share with their vendors. Remarkably, around 70% of companies in certain sectors have reported at least one instance of this type of attack, indicating its prevalence.
Email spoofing is a common tactic within these phishing operations, allowing cybercriminals to forge emails so they seem to be sent by actual vendors. Such deception makes it difficult for the recipients to detect the scam.
