What Is a Business Email Compromise? Signs, Types, and Prevention

Business emails are key channels of daily communication for organizations. The organization uses business emails to communicate with its workers, customers, and vendors. The purpose of using business emails is to share business information, billing invoices, and payments. Business emails are prone to cyber fraud by cybercriminals. 

Cybercriminals may use the method of email impersonations, phishing attacks, or account takeover to conduct such frauds. The result of cyberattacks is financial loss and the theft of sensitive data by cybercriminals. It is essential for businesses to have good business email security strategies to avoid such situations.

Why Are BEC Attacks So Hard to Detect?

BEC attacks are difficult to notice because the emails appear like usual emails that are sent within the organization for business purposes. The criminals pose as people who have good relations with the victims, such as executives, employees, or vendors in the organization. The cybercriminals may also employ fake or compromised emails to give their attack a professional look. 

The main difference between traditional phishing attack emails and BEC emails is that the latter do not have any links or attachments in them. The hackers try to create a feeling of urgency by requesting payments from the employees.

What Do BEC Emails Usually Contain?

Fraudulent emails in BEC attacks will normally feature false payment requests or requests for sensitive information. Such attackers may pose as CEOs, vendors, employees, or partners of your company. Fake invoices, bank account changes, or instructions to wire money urgently can be found within these types of emails. There are those that will ask for login credentials or information regarding your payroll. 

Such attackers could employ email spoofing techniques or have access to compromised email accounts to make their requests seem legitimate. AI technology will also produce well-written emails that contain only a few errors in spelling. Unlike typical phishing emails, BEC emails do not have any malware embedded.

Protect Against BEC Attacks

Precautionary measures can be taken by organizations to mitigate the risk of being victimized by BEC attacks. It is important that employees undergo security awareness training frequently in order to be able to detect phishing emails and email impersonation. Multi-factor authentication (MFA) will be yet another line of defense for business email accounts. 

Organizations can verify any payments and changes to banking accounts using a verified telephone number. Email authentication policies, such as SPF, DKIM, and DMARC, can be used to counter email spoofing. Suspicious login activities and email forwarding can also be monitored.

Legal and Regulatory Considerations

Companies are required to take into account the legal and regulatory issues that arise in relation to the prevention of BEC attacks. The laws of protecting personal data may oblige companies to secure sensitive data and disclose some types of data breaches. Business fraud may result in legal proceedings and financial losses for a company. 

Companies need to have well-formulated security policies and comply with cybersecurity regulations. Employees should be aware of the proper handling of the company’s sensitive information. Companies need to document suspicious emails and payments. In case of BEC attacks, companies need to notify the bank and report the incident.

Do Secure Email Gateways Block BEC?

Secure Email Gateways (SEGs) are among the ways that can be used by organizations to protect themselves against email cyber attacks. They are able to detect spam emails, phishing, links, or attachments in the email. It is impossible to completely defend the organization against BEC attacks. The BEC email usually mimics the appearance of legitimate business emails and does not contain any malicious links or attachments. 

Hackers can make use of email spoofing or hijacked email addresses to make their attacks succeed. SEGs will become ineffective under such conditions. Organizations need to use SEGs together with MFA and other methods of cybersecurity.

What Should Users Do When They Suspect BEC?

Users need to respond swiftly in case of suspicion of a BEC attack. The users need to stop from responding to such emails and avoid clicking any link provided by it. Any strange payment request needs to be confirmed by a legitimate phone call. Employees need to notify their IT/security team of any suspicion of email fraud. 

It will be necessary for the organization to change passwords, invalidate existing logins, and investigate suspicious email rules. Organizations need to keep emails as evidence and look into any other malicious activities. If there are any money transfers, then organizations need to contact the bank and recall the payments.
