Fraudsters use increasingly sophisticated tactics to exploit busy teams, trusted vendor relationships, and financial workflows. Understanding these scams is one of the best ways to prevent them. Here are the most frequent schemes affecting businesses today.

Business Email Compromise (BEC)

Criminals impersonate company executives, employees, or vendors to trick staff into sending payments or sensitive information.

Red Flags:

  • Requests to update account details via email
  • Unusual urgency or secrecy
  • Messages that appear slightly “off” in tone or grammar

Corporate Account Takeover Attempts

Once criminals acquire credentials through phishing or malware, they attempt to log in to online banking or business systems.

Warning signs:

  • Login attempts from unusual locations
  • Locked accounts
  • Profile changes you didn’t initiate

Phishing, Smishing & Vishing

Attackers use email (phishing), text (smishing), or phone calls (vishing) to acquire credentials or financial access. 

Tactics may include:

  • “Urgent” login requests
  • Fake security alerts
  • Spoofed bank representatives
  • Links leading to fake login pages

Check Fraud

Checks can be stolen, altered, washed, or counterfeited. 

Watch out for:

  • Missing checks
  • Vendors reporting unpaid invoices
  • Check amounts or payees that don’t match your records

Vendor or Invoice Fraud

Scammers pose as legitimate vendors and send fake invoices or request changes to payment information. Even long‑standing vendor relationships can be targeted by fraudsters.

How it works:

  • Fraudsters intercept or spoof vendor communications
  • They provide new routing or account numbers
  • Payments end up in criminal accounts

Payroll & HR Impersonation Scams

Fraudsters pretend to be employees requesting updates to direct deposit information. 

Typical pattern:

  • Email appears to come from an employee
  • Fraudster asks payroll to update their bank account
  • Paychecks get redirected to the criminal’s account

Tech Support & Remote Access Scams

Scammers impersonate trusted software providers to trick employees into granting remote access. Once inside, criminals may capture credentials or plant malware.

Look for:

  • Unexpected computer or mobile device pop‑ups
  • Calls claiming your system is compromised
  • Requests to download remote‑access tools

ACH & Wire Transfer Fraud

Fraudsters target high‑speed, high‑value payment methods. Because these transactions move quickly, early detection is critical.

Common scenarios:

  • Fake wire requests from “executives”
  • Fraudulent ACH pulls
  • Manipulated invoices

✔ Password & Access Security

  • Use long, unique passwords
  • Store credentials in a password manager
  • Restrict admin access
  • Remove access for former employees immediately

✔ Account & Payment Protection

  • Enable multi factor authentication for banking, email, and accounting tools
  • Confirm vendor payment changes with a trusted phone number
  • Require dual approvals for wires and ACH
  • Set alerts for outgoing payments and suspicious logins

✔ System & Device Security

  • Keep software and operating systems updated
  • Install reputable anti‑malware tools
  • Run regular device scans
  • Avoid public Wi‑Fi for sensitive activity

✔ Staff Awareness & Training

  • Teach employees to recognize phishing attempts
  • Share examples of current scams
  • Provide refresher training annually
  • Reinforce that all suspicious requests should be reported

✔ Data & Network Safety

  • Back up important business data
  • Encrypt sensitive files
  • Use strong Wi‑Fi passwords
  • Provide VPN access for remote workers

✔ Ongoing Account Monitoring

  • Review online banking activity frequently
  • Monitor vendor account details
  • Audit user permissions periodically
  • Investigate unexpected deposits or withdrawals

If anything feels unusual — a strange email, an unexpected payment request, or account activity you don’t recognize — take action right away. Here’s what to do:

  • Stop the activity immediately
    Pause any payments, approvals, or responses connected to the suspicious request.

  • Contact us right away
    Reach out to your banking team as soon as possible so we can help secure your accounts and investigate.

  • Document what you see
    Save emails, screenshots, invoices, phone numbers, or messages related to the suspicious activity.

  • Notify your internal team
    Inform your supervisor, finance department, and IT staff to prevent repeated attempts.

  • Secure your systems
    Change any passwords that may have been exposed and consider running malware or security scans.

  • Verify with a trusted source
    If it involves a vendor, employee, or partner, call them using a known phone number. Not one provided in the suspicious message.

  • Monitor your accounts closely
    Review transactions and alerts over the next several days, as fraud attempts often come in clusters.
