Vendor Email Compromise (VEC) is a growing type of cyber scam that targets the trust between companies and their vendors. Unlike other email scams, VEC focuses on tricking businesses into paying money to the wrong person, using fake invoices or payment change requests. Understanding how VEC works and how to protect your business is important to avoid serious financial loss.
How Does Vendor Email Compromise (VEC) Work?
In a VEC attack, cybercriminals hack into a vendor’s email account and use it to send fake requests for payment. These requests often look real because the attacker uses stolen information, like previous invoices, to make the email seem trustworthy.
Example of a Vendor Email Compromise Attack
Let’s look at a real-world example of VEC:
A construction company works with a long-time supplier of building materials. One day, the supplier’s email is hacked by cybercriminals. The attacker then sends a legitimate-looking invoice to the construction company, claiming that the company’s bank account has changed due to new financial policies. The email appears to come from the trusted vendor and contains real details from previous invoices, making the request appear credible.
Trusting the email’s authenticity, the construction company wires a large payment to the “new” bank account, which, of course, belongs to the attacker.
This type of attack is becoming more common and can result in significant financial losses if businesses do not take the necessary precautions.
How to Protect Your Business from Vendor Email Compromise (VEC)
Preventing Vendor Email Compromise (VEC) requires a multi-faceted approach that combines technology, policy, and employee vigilance. Below are effective mitigation strategies to help businesses safeguard their operations from this evolving threat.
- Leverage AI for Detection and Prevention:
AI-powered tools can help detect suspicious email activity, such as unusual login patterns or unexpected requests for payment changes. AI can quickly identify anomalies in communication, which are key to stopping a VEC attack before it escalates. - Strengthen Email Authentication:
Implementing multi-factor authentication (MFA) and enforcing strong password policies can make it much harder for cybercriminals to gain unauthorized access to email accounts. Tools like SPF, DKIM, and DMARC also improve the security of emails sent between businesses and vendors. - Educate Employees on Cybersecurity Best Practices:
Employee training is critical in defending against VEC. Staff should be trained to recognize phishing attempts, verify payment changes directly with vendors through alternate communication channels (e.g., phone calls), and report suspicious activities promptly. - Implement Vendor Management Controls:
A formal vendor management program can help mitigate VEC risks. This should include procedures for verifying payment changes and regular audits of vendor relationships. Establishing direct communication channels and ensuring that vendors are aware of your security protocols can reduce the likelihood of successful VEC attacks. - Conduct Regular Security Assessments:
Routine security assessments and penetration testing help identify vulnerabilities in your systems before attackers can exploit them. Regular reviews of email security practices, access controls, and internal communication protocols can help businesses stay ahead of potential threats.
