The Business Executive's Guide to Detecting and Preventing Impersonation Scams

Impersonation scams are a growing threat to businesses of all sizes and industries. These attacks involve cybercriminals posing as a trusted person or entity, such as a CEO or vendor, to trick employees into divulging sensitive information, transferring money, or granting access to corporate systems. Impersonation scams can be challenging to detect and cause significant financial and reputational damage to organizations.

Top business executives are particularly at risk for these attacks, as they are often targeted due to their high-level access and authority within the company. As such, it is essential for executives to be aware of the warning signs of impersonation scams and to implement best practices for preventing these attacks from succeeding.

This article will provide a comprehensive guide for business executives on detecting and preventing impersonation scams. We will cover the different types of impersonation scams, the warning signs to look out for, and the best practices for protecting against these attacks.

Following this guide's advice, executives can better defend their businesses against this growing threat and safeguard their company's financial and reputational well-being.

Types of Impersonation Scams

Business executives should be aware of several types of impersonation scams to defend against them effectively. Some of the most common types include:

CEO Fraud

This type of scam involves a cybercriminal posing as a high-ranking executive, such as a CEO or CFO, and requesting that an employee transfer funds or sensitive information. The email or message will often appear urgent and require a quick response, leaving little time for the employee to question the request's legitimacy. Even most vigilant employees make mistakes because they consider something urgent and often don’t have the time for analysis.

Vendor Impersonation

In this type of scam, a cybercriminal pretends to be a vendor or supplier that the company works with regularly. They will typically request a change in payment details or send a fake invoice, hoping to trick the company into sending funds to the wrong account.

Business Email Compromise (BEC)

BEC attacks involve a cybercriminal impersonating an employee or vendor and requesting that funds be transferred to a fraudulent account. These attacks often involve significant planning and research, with cybercriminals gathering information about the company and its employees to create a convincing impersonation.

Some examples of high-profile impersonation attacks include recently reported CEO fraud resulting in the dismantling of the Franco-Israeli criminal network, the 2019 Wipro phishing scam, where cybercriminals impersonated Wipro IT technicians and used their access to launch phishing attacks on Wipro clients and the 2020 Twitter hack, where cybercriminals impersonated employees to gain access to high-profile accounts and post fraudulent tweets.

By understanding the different types of impersonation scams and their methods of operation, business executives can better prepare themselves and their employees to detect and prevent these attacks.

Warning Signs of Impersonation Scams

Impersonation scams can be difficult to detect, but there are some warning signs that business executives and their employees can look out for to help identify potential attacks. Here are some common signs that an impersonation attack may be in progress:

• Urgent Requests for Money Transfers - Impersonation scams often involve urgent requests for money transfers or changes to payment details. Employees should be suspicious of any request with a tight deadline or deviating from standard payment procedures.
• Changes to Payment Details - Similar to the above, cybercriminals may request changes to payment details, such as the bank account or address to which a payment is sent. These changes may be subtle, such as a single-digit difference in the bank account number, so it is important to double-check any changes before proceeding.
• Suspicious Emails - Emails are a standard tool used in impersonation scams, and several red flags can indicate a fraudulent message. These include messages from unknown senders, personal or sensitive information requests, and messages containing grammatical errors or unusual formatting.
• Phone Calls from Unknown Numbers - Cybercriminals may use phone calls to impersonate someone from within the company, a vendor, or a supplier. Employees should be wary of phone calls from unknown numbers, particularly those that request sensitive information or urgent action.

To help identify potentially fraudulent emails, phone calls, and other forms of communication, business executives can implement several best practices. These include verifying the sender's identity, using two-factor authentication for sensitive transactions, and avoiding clicking on links or downloading attachments from unknown sources. By staying vigilant and adopting a cautious approach to suspicious communication, businesses can better protect themselves against impersonation scams.

Best Practices for Preventing Impersonation Scams

Preventing impersonation scams requires a multi-faceted approach that involves both technical and human defences. Here are some of the most effective strategies for preventing impersonation attacks:

• Two-Factor Authentication - Two-factor authentication is a security measure that requires users to provide two forms of identification to access an account or perform a transaction. This can include a password and a code sent to the user's phone or email. By requiring two forms of identification, businesses can significantly reduce the risk of impersonation attacks.
• Employee Training - Employee training is crucial to preventing impersonation scams, as employees are often the first line of defence against these attacks. Regular training sessions can educate employees on the warning signs of impersonation scams and best practices for protecting sensitive information and verifying the identity of senders.
• Strong Password Policies - Strong password policies are another essential defence against impersonation scams. Employees should be required to use complex passwords that are changed regularly, and multi-factor authentication should be implemented for particularly sensitive accounts.
• Staying Up to Date with Security Tools and Technologies - Cybersecurity is an ever-evolving field, and businesses must stay up-to-date with the latest security tools and technologies. This can include firewalls, anti-virus software, intrusion detection systems, regular security assessments, and penetration testing. 

Responding to Impersonation Scams

Even with the best prevention measures in place, businesses may still fall victim to impersonation scams. In the event of an attack, it is essential for business executives to respond quickly and effectively. Here are the steps that should be taken if an impersonation attack is suspected:

• Notify Law Enforcement - Impersonation scams are illegal. They can result in significant financial and reputational damage to businesses. As such, executives should immediately notify law enforcement, such as the FBI or local police, if they suspect an attack has occurred.
• Implement Damage Control Measures - Businesses should implement damage control measures to limit the attack's impact once an attack has been identified. This may include freezing accounts, changing passwords, and notifying customers or other stakeholders of the attack as soon as possible.
• Recover from the Attack - Recovering from an impersonation attack can be a lengthy and complex process. Businesses may need to conduct a thorough investigation to identify the scope of the attack and determine what information or assets have been compromised. It is also necessary to work with legal and security experts to implement more robust prevention measures and ensure that the attack does not happen again in the future.

Impersonation scams are a growing threat to businesses worldwide, and business executives need to be aware of the warning signs and best practices for preventing and responding to these attacks. By implementing strong prevention measures, such as two-factor authentication and employee training, and responding quickly and effectively in the event of an attack, businesses can significantly reduce the risk of financial and reputational damage.
