Combatting deepfake and sophisticated invoice fraud with AI


The rapid evolution of artificial intelligence has transformed industries worldwide, but it has also introduced new threats—particularly in financial operations like accounts payable (AP). One of the most alarming trends is the rise of deepfake and sophisticated invoice fraud. Fraudsters are now using AI-generated manipulations to bypass traditional security measures, making it harder than ever to detect fraudulent invoices.

As these threats grow in complexity, businesses must adopt equally advanced solutions. AI-driven technologies, like those offered by Medius, provide a crucial line of defense, enabling AP teams to detect, flag, and prevent fraudulent transactions before they cause financial harm.

The rise of deepfake and sophisticated invoice fraud

Invoice fraud is nothing new, but the increasing use of AI in fraudulent schemes has made detection significantly more challenging. Traditional fraud tactics—such as invoice duplication, fake vendor accounts, or account takeovers—are now being enhanced with AI-generated deepfakes and automation.

Here’s how fraudsters are leveraging AI to exploit AP systems:

Deepfake audio & video scams

Fraudsters use AI-generated voices or video deepfakes to impersonate executives or suppliers, instructing or luring AP teams to approve payments to fraudulent accounts.

Synthetic invoices

Scammers create highly realistic fake invoices using AI, making them nearly indistinguishable from legitimate ones. These invoices can mimic real vendor details, logos, and transaction histories.

Compromised email and chat communications

AI-powered chatbots can mimic supplier or executive communication styles, tricking AP staff into processing unauthorized payments.

Automated fraud at scale

AI enables fraudsters to generate and submit thousands of fraudulent invoices automatically, overwhelming manual review processes.

With fraudsters deploying AI to outmaneuver traditional detection methods, organizations must leverage equally advanced defenses to stay ahead.

How AI can detect and prevent invoice fraud

The fight against AI-powered fraud requires AI-powered solutions. Advanced AI and machine learning can analyze invoices in real time, identify anomalies, and detect fraudulent patterns that human review alone might miss. Key AI-driven fraud prevention strategies include:

  • Behavioral pattern recognition

    AI analyzes past transactions, flagging invoices that deviate from normal vendor behavior. If a supplier suddenly submits an unusually high-value invoice or changes payment details, AI can issue an alert.

  • Real-time anomaly detection

    Machine learning continuously scans invoices for irregularities, such as inconsistencies in formatting, altered bank details, or discrepancies in invoice numbers.

  • Deepfake detection

    AI tools can identify manipulated voices, images, and video deepfakes to prevent fraudulent communications from influencing payment approvals.

  • Automated invoice matching

    AI ensures that invoices align with purchase orders and contracts, preventing unauthorized payments.
