How to Prevent Vendor Email Compromise Attacks

You know how annoying it is when your favorite pizza joint gets your order wrong? Well, imagine if it wasn’t just a wrong order but a scam email pretending to be your trusted vendor, tricking you into sending thousands of dollars to a fraudster. Welcome to the world of Vendor Email Compromise (VEC). Let’s dive in and make sure you aren’t on the menu for the next cyber-attack.

Vendor Email Compromise (VEC) occurs when hackers impersonate a legitimate vendor’s email account to deceive businesses into transferring money or providing sensitive information. Similar to Business Email Compromise (BEC), VEC attacks are sophisticated and target a vendor's customers, causing financial and reputational damage.


How It Works:

Here’s the play-by-play of a typical VEC attack:

  1. Research: Cybercriminals thoroughly study the vendor, learning everything from financial details to customer interactions.
  2. Phishing: Hackers send targeted phishing emails to vendor employees, hoping to gain access to their email accounts.
  3. Account Takeover: Once they have access, the scammers monitor communications to learn the ins and outs of the vendor’s business.
  4. Execution: The final phase—hackers impersonate the vendor and send fake invoices or payment requests to their customers, asking for money to be sent to fraudulent accounts.

If successful, the victims unknowingly send large sums of money to cybercriminals, often losing thousands before realizing something’s wrong.


Who’s Targeted:

Small and large businesses alike are at risk, especially companies that regularly make payments to vendors. VEC attacks are often aimed at finance departments and CFOs, as they handle sensitive financial transactions. Attackers focus on industries with high cash flow and frequent vendor payments, like construction, manufacturing, and technology.


Real-Life Example:

A large construction company fell victim to a VEC attack when cybercriminals compromised their vendor’s email. The hackers, posing as the vendor, sent an urgent invoice for $150,000, which the company quickly paid. It wasn’t until weeks later—when the real vendor inquired about the overdue payment—that they realized the money was gone. By then, the funds had been transferred to multiple accounts overseas, making recovery almost impossible.


Why You Should Care:

VEC attacks don’t just steal your money—they steal your trust. When you lose money to a fraudster posing as your trusted vendor, it damages relationships and can create chaos in your business’s financial operations. If you’re not prepared, you could be the next target.


How to Protect Yourself:

Here’s how to safeguard your business against VEC attacks:

  1. Verify Payment Requests: Always confirm payment requests through a secondary communication method. Call or text your vendor to confirm the details before making any transfers.
  2. Educate Employees: Train staff regularly on recognizing phishing emails and other signs of VEC attacks. Awareness is your best defense.
  3. Use Multi-Factor Authentication (MFA): Protect email accounts with MFA, requiring more than just a password to gain access.
  4. Monitor Email Traffic: Use advanced email filtering tools to spot suspicious emails, especially those involving financial transactions.
  5. Check Email Extensions: Hackers often use email addresses that are nearly identical to the real ones. Always double-check the sender’s email for any slight misspellings.


Quick Tips:

  • Did you know? Cybercriminals often launch VEC attacks around billing cycles, knowing that businesses are more likely to process payments without question.
  • Pro Tip: Regularly update your spam filters and ensure your email security protocols are as sophisticated as the fraudsters targeting you.
