Account Takeover fraud is a growing threat to businesses of all sizes. In an Account Takeover attack, criminals gain unauthorized access to a legitimate business account, often online banking, to move money, change account details, or hide fraudulent activity.

What Is Account Takeover fraud?

Account Takeover fraud occurs when a criminal uses stolen or compromised credentials to sign in as an authorized user. This is often the result of:

• Stolen or reused passwords.
• Compromised business email accounts.
• Social engineering tactics that trick users into sharing information.

Once attackers gain access, they appear as a legitimate user, making the fraud harder to detect.

How Do Account Takeovers Happen?

Fraudsters use several common methods to gain access to business accounts:

• Phishing Emails: Attackers send emails that appear to come from a trusted source, prompting users to click a link or enter credentials on a fake website.
• Compromised Email Accounts: If a business email account is breached, criminals can intercept messages, reset passwords, or impersonate employees.
• Weak or Reused Passwords: Using the same password across multiple systems increases risk. If one site is breached, attackers may try the same credentials elsewhere.
• Malware: Clicking malicious links or downloading infected files can install malware that captures keystrokes or login credentials.
• Unsecured Devices and Public Wi‑Fi: Using public or unsecured networks can expose login activity to interception by criminals.

What Can Fraudsters Do Once Inside?

After gaining access to an account, criminals may:

• Initiate wire transfers.
• Add or change payment recipients.
• Create fraudulent ACH files.
• Modify contact information to delay detection.

Because these actions occur within a legitimate account, they may initially appear normal.

How to Safeguard Your Business

Taking a few proactive steps can help lower the potential impact of Account Takeover fraud:

• Enable multifactor authentication (MFA) for all users.
• Use strong, unique passwords and avoid reusing them.
• Review employee access rights regularly and remove access when it’s no longer needed.
• Monitor online banking activity daily to spot unusual behavior.
• Keep software and browsers up to date with the latest security patches.

Stay Vigilant

Account Takeover fraud is a serious but preventable risk. By understanding how these attacks happen and following best practices, your business can strengthen its defenses and reduce overall exposure to fraud.
