A compromised business bank account can be a nightmare for any company. Whether due to cyberattacks, fraud, or an employee’s mistake, unauthorized transactions and potential financial losses require immediate action. A delayed response can worsen the situation, leading to drained funds, stolen customer data, and damaged business credibility.
So, what should you do if your business bank account has been compromised? This guide outlines the crucial steps to take immediately and best practices to prevent future incidents.
How Can You Tell If Your Business Bank Account Has Been Compromised?
Several warning signs may indicate that your business bank account has been breached:
- Unauthorized transactions – Unexpected withdrawals, wire transfers, or purchases you didn’t authorize.
- Login attempts from unknown locations – Alerts from your bank about suspicious login attempts.
- Changes to account details – Unauthorized modifications to your business name, contact information, or linked accounts.
- Locked-out access – If you suddenly cannot log in, cybercriminals may have taken over the account.
- Unexpected charges or overdraft notices – Charges for services you didn’t request or sudden overdrafts when you had sufficient funds.
If you notice any of these signs, act immediately to prevent further financial damage.
What Should You Do Immediately After Discovering a Compromise?
1. Contact Your Bank Immediately
Time is of the essence. Call your bank’s fraud department as soon as you notice suspicious activity. Ask them to:
- Freeze or restrict transactions to prevent further unauthorized withdrawals.
- Reverse any fraudulent transactions if possible.
- Investigate the source of the compromise and provide you with a fraud report.
- Issue new account details if necessary.
🔹 Pro Tip: Most banks have a 24/7 fraud hotline—keep it saved in case of an emergency.
2. Change All Online Banking Passwords and Security Credentials
Once your bank is alerted, secure your account credentials immediately.
- Use a strong, unique password that isn’t shared with any other accounts.
- Enable multi-factor authentication (MFA) for added security.
- Update security questions, PINs, and linked email addresses.
3. Review All Recent Transactions
Go through your transaction history for unauthorized charges. Flag any suspicious activity to your bank and dispute fraudulent transactions immediately.
- Check for small test transactions—these may indicate cybercriminals verifying card details before making larger withdrawals.
- Ensure no new payees or auto-pay setups have been added without your knowledge.
4. Alert Employees and Financial Teams
If your business has multiple employees handling finances, notify them immediately to:
- Stop all banking activity until the issue is resolved.
- Verify payments before processing any new transactions.
- Check internal systems for potential malware or unauthorized access.
5. Scan Your Systems for Malware or Breaches
Cybercriminals often compromise bank accounts through malware, phishing emails, or keyloggers that record login credentials.
- Run a full security scan on all company devices.
- Update antivirus software and remove any suspicious programs.
- Change all passwords for company email accounts and financial software.
6. Report the Fraud to Authorities and Credit Bureaus
Depending on the severity of the compromise, report the incident to relevant authorities:
- Federal Trade Commission (FTC) – File a report at IdentityTheft.gov.
- Local law enforcement – If funds were stolen, file a police report.
- Credit bureaus – If company credit was affected, notify Equifax, Experian, or TransUnion.
7. Notify Affected Customers or Vendors (If Necessary)
If the breach involved customer payment data or vendor transactions, transparency is key.
- Inform customers of potential risks and advise them to monitor their bank accounts.
- Work with vendors to ensure payments were not rerouted to fraudulent accounts.
How Can You Prevent Future Business Bank Account Breaches?
1. Enable Multi-Factor Authentication (MFA) on Banking Accounts
MFA requires an extra step (such as a text code or authentication app) before logging in, making it harder for hackers to access your account.
2. Restrict Account Access and Use Role-Based Permissions
- Limit banking access to only essential personnel.
- Use separate logins for each employee rather than sharing credentials.
- Set spending limits and approval workflows for wire transfers.
3. Monitor Account Activity Regularly
- Set up real-time alerts for large transactions, logins from new locations, and balance changes.
- Review monthly statements for unusual activity.
4. Train Employees on Fraud Awareness
Employees should know how to:
- Identify phishing emails pretending to be from the bank.
- Avoid clicking suspicious links or downloading attachments from unknown senders.
- Report unauthorized access attempts immediately.
5. Use Secure Networks and Devices for Online Banking
- Avoid public Wi-Fi when accessing financial accounts.
- Use a VPN for secure internet connections.
- Ensure company computers have updated firewalls and security software.
6. Keep Business and Personal Finances Separate
Having a dedicated business bank account ensures personal transactions don’t interfere with business security. It also makes fraudulent activity easier to detect.
