The Resurgence of Check Washing Fraud: How AI is Fueling a Classic Crime

Check washing, a seemingly archaic form of fraud, is experiencing a dangerous resurgence, amplified by the sophisticated capabilities of artificial intelligence (AI). Once a low-tech crime involving household chemicals to erase and alter checks, it has evolved into a high-tech threat capable of causing significant financial damage to individuals and businesses alike.

Understanding Check Washing

At its core, check washing involves stealing a physical check, often from unsecured mailboxes, and using solvents like acetone or nail polish remover to remove the ink containing the payee name and amount. The signature usually remains intact, making the altered check appear legitimate. Scammers then rewrite the check to themselves or a third party and for a much larger sum.

The AI Revolution in Check Washing

The integration of AI into fraudulent activities has added a new layer of complexity and scale to check washing. Here’s how scammers are leveraging AI:

• Enhanced Forgery and Counterfeiting: AI-powered tools can generate realistic-looking fake identification documents, making it easier for fraudsters to open accounts to deposit altered checks. They can also create convincing counterfeit checks from scratch using stolen account information and AI-generated signatures.
• Sophisticated Image Manipulation: AI algorithms can be used to subtly alter scanned images of checks, making the “washed” areas appear seamless and undetectable by traditional fraud detection systems. This allows for remote deposit of fraudulent checks.
• Synthetic Identity Fraud: By combining AI-generated fake documents with stolen personal information, criminals can create entirely new, synthetic identities. These identities are then used to open bank accounts and cash fraudulent checks, making it harder to trace the funds.
• Business Email Compromise (BEC) Enhancement: AI can craft highly convincing phishing emails that impersonate executives or vendors. These emails can trick employees into sending legitimate checks to fraudulent accounts, which are then altered.
• Circumventing Security Measures: AI can analyze banking security systems and identify vulnerabilities, allowing scammers to tailor their techniques to bypass these measures more effectively.

The Growing Threat

The combination of traditional check washing tactics with advanced AI capabilities makes this form of fraud particularly dangerous because:

• Low Technical Barrier (Initial Stage): The initial act of stealing and washing a check doesn’t require significant technical expertise.
• Delayed Detection: Checks can take days or weeks to clear, giving criminals ample time to deposit altered checks and withdraw funds before the victim or the bank notices any discrepancies.
• Difficulty in Tracing: Once the funds are moved, especially through multiple accounts opened with synthetic identities, tracing the money back to the perpetrators becomes incredibly challenging.
• Increased Sophistication: AI tools make the forgeries and alterations more realistic and harder for humans and traditional systems to detect.

Protecting Yourself and Your Business

While the threat is evolving, there are steps you can take to mitigate the risk of check washing fraud:

• Use Security Pens: Always write checks with a black gel pen, as the ink is more difficult to wash.
• Secure Your Mail: Deposit outgoing mail, especially containing checks, directly at the post office or in secure USPS collection boxes. Retrieve your mail promptly after delivery and consider using a locked mailbox. If you’re away, request the postal service to hold your mail.
• Monitor Bank Accounts Diligently: Set up real-time alerts for check clearing and review your bank statements frequently for any suspicious activity. Report any discrepancies immediately.
• Consider Digital Payment Methods: Opt for electronic payment methods like online bill pay, ACH transfers, or services like Zelle for personal transactions whenever possible to avoid the use of physical checks altogether.
• Implement Positive Pay (for Businesses): This bank service matches the checks your company issues with those presented for payment. Any discrepancies in the account number, check number, or amount are flagged for review before payment. Some advanced systems also include “payee positive pay,” which verifies the payee name.
• Limit Check Access (for Businesses): Restrict the number of employees who have access to checks and check-writing software.
• Use High-Security Checks (for Businesses): Utilize checks with security features like watermarks and microtext, which are harder to counterfeit.
• Be Cautious with Endorsements: When endorsing checks for deposit, write “For Deposit Only” along with your account number.
• Report Suspicious Activity Immediately: If you suspect a check has been stolen or altered, contact your bank right away. You should also report mail theft to the U.S. Postal Inspection Service and file a complaint with the Federal Trade Commission (FTC) at IdentityTheft.gov.

AI to the Rescue?

Interestingly, AI is not only being used by fraudsters but also to combat check fraud. Financial institutions are increasingly employing AI-powered tools for:

• Advanced Image Analysis: AI can analyze check images for alterations, inconsistencies in handwriting, and signs of counterfeiting that might be missed by human reviewers or traditional OCR (Optical Character Recognition) systems.
• Behavioral Analytics: AI algorithms can learn typical account activity patterns and flag unusual transactions, including suspicious check deposits.
• Dark Web Monitoring: AI can scan the dark web for stolen check information, alerting banks and potentially affected individuals.
• AI Agents for Investigation: Some platforms use AI to automate parts of the fraud investigation process, speeding up the identification and resolution of fraudulent activities.

The resurgence of check washing fraud, now fueled by the power of AI, presents a significant threat in today’s financial landscape. By understanding these evolving tactics and implementing robust preventative measures, individuals and businesses can better protect themselves from becoming victims of this increasingly sophisticated crime. Staying vigilant and leveraging the latest security tools, including AI-powered solutions, is crucial in this ongoing battle against fraud.
