Protecting your enterprise from vendor email compromise attacks is a huge challenge in today’s dynamic digital world. These Vendor Email Compromise (VEC) attacks, which frequently leverage advanced phishing kits, exploit the trust between companies and their vendors.
This article explains how VEC attacks work and how our cybersecurity consulting services can help fortify your organization against such attacks.
What is Vendor Email Compromise (VEC) Attack?
Vendor Email Compromise (VEC) is a sophisticated cyberattack in which malicious actors impersonate vendors to deceive customers. Unlike typical phishing attacks, VEC involves gaining access to or mimicking a vendor’s email account to send fraudulent messages.
These emails often appear legitimate, causing recipients to divulge sensitive information or send money. The financial damage from such attacks can be significant, resulting in monetary loss and damaging the vendor’s reputation. This loss of trust can have long-term effects on business relationships, making vigilance a critical necessity.
Understanding How VEC Attacks Work
VEC attacks typically unfold in several stages: research, phishing, account takeover, and execution. Each stage is meticulously planned and executed to maximize success.
1. Research Phase
The initial stage involves comprehensive research, during which attackers gather detailed information about the target vendor using publicly available data to construct a convincing vendor profile. They scrutinize the vendor’s revenue, financial structures, customer interactions, and workflow processes. By doing so, attackers ensure their fraudulent communications appear as legitimate as possible, increasing the likelihood of deceiving the vendor’s customers.
2. Phishing and Observation
Once attackers have gathered sufficient information, they launch phishing campaigns aimed at vendor staffers. The goal is to gain email account access by tricking staffers into clicking on malicious links or downloading harmful attachments. During this phase, attackers often maintain a low profile, observing legitimate communications to blend in seamlessly. This observation period allows them to understand the language and context of the vendor’s emails, making their fraudulent messages more convincing.
3. Account Takeover and Persistence
After successfully phishing the target, attackers seize control of email accounts and establish monitoring rules. These rules help them track specific communications, such as financial records and payment schedules. Attackers may also create mail rules to retain access, ensuring they can continue to receive and send messages even if the vendor regains account control. This persistence tactic is crucial for maintaining their foothold within the compromised system.
4. Execution Phase
In the final stage, attackers use the information gathered to execute their attack. They craft targeted phishing campaigns to deceive the vendor’s customers into believing the emails are legitimate. Attackers send fake invoices or payment instructions, directing customers to transfer funds to their accounts. Once the funds are transferred, attackers often vanish, leaving both the vendor and the customer to manage the financial fallout.
Recognizing the tactics used in the research and phishing phases can better prepare your defenses against VEC attacks. This will help you better understand the specific tactics employed in these initial stages.

Detection and Prevention Strategies for Vendor Email Compromise
Detecting and preventing Vendor Email Compromise attacks require several strategies, including:
- Pairing basic spam and phishing filters with advanced tools like antimalware and email protection platforms.
- Conducting regular security awareness training to empower employees to recognize phishing attempts.
- Implementing strict access controls, such as secure email gateways and endpoint protection measures.
- Requiring multi-factor authentication (MFA) to add an extra layer of security.
By integrating these strategies, organizations can significantly enhance their defences against VEC threats, creating a more secure communication environment.
