Money mule fraud cases are up over 160%, and your startup could be next

How money mules target business operations

Money mules are people or entities who transfer stolen money or illicit funds on behalf of criminals. What makes them particularly dangerous is that many participants don't realize they're facilitating money laundering. The criminal organizations behind these schemes have evolved dramatically, abandoning their traditional focus on recruiting vulnerable individuals in favor of systematically targeting businesses.

Startups are attractive targets because they:

• Have limited fraud prevention infrastructure
  
• Regularly process international payments
  
• Use multiple payment platforms and banking relationships
  
• Maintain teams focused on rapid growth and might overlook security protocols in favor of speed
  

Whether you knowingly or unknowingly participate in these fraudulent schemes can mean legal and regulatory consequences for your business. Here’s the difference:

• Unknowing businesses typically get manipulated through sophisticated Business Email Compromise attacks, fake vendor communications, or compromised payment instructions that exploit normal business processes.
  
• Knowing participants deliberately join schemes, often recruited through "side hustle" opportunities that promise easy money for moving funds.
  

Nearly 2 million money laundering accounts were reported globally in 2024, with financial institutions reporting a clear trend toward business account targeting. For fast-growing companies managing multi-currency payments and expanding internationally, these complex financial flows and global vendor relationships create heightened vulnerability that criminals actively exploit.

7 ways fraudsters infiltrate your startup

Understanding how these schemes work helps you recognize and prevent them before they can damage your business.

1. Business Email Compromise
   

BEC attacks generated $2.9 billion in losses from 21,832 incidents in 2024, making this the most financially damaging fraud targeting businesses today.

Criminals invest significant time researching target companies, identifying key personnel, and understanding normal business processes before striking. They compromise or create convincing spoofs of business email accounts, then target companies known for regular wire transfers or international payments. The "urgent" requests to redirect payments to mule accounts often impersonate executives, suppliers, or trusted partners with remarkable accuracy.

Their attacks are strategic and well-timed. Attackers deliberately wait for high-pressure periods like quarter-end closings when finance teams are overwhelmed and rushing to process payments. During these windows, the normal skepticism that might catch suspicious requests gets overridden by operational urgency.

1. Fake vendor and supplier schemes
   

These attacks begin with extensive reconnaissance. Criminals research your actual vendor relationships through publicly available information - your website, social media posts, business filings, and even job listings that mention specific software or service providers. They use this intelligence to create convincing fake communications requesting bank detail updates.

Criminals deliberately target end-of-quarter periods, product launches, or other high-stress times when teams are most likely to prioritize speed over verification. Warning signs include sudden changes to payment instructions without prior discussion, requests for secrecy about the changes, or unusual pressure to bypass normal approval processes that would typically catch these schemes.

1. Investment cons
   

These cons are a growing trend that exploits startup founders' risk tolerance and growth mindset. These schemes present fake investment opportunities requiring business account transfers, promise guaranteed returns for "helping" with money transfers, or involve cryptocurrency conversion schemes using business accounts as intermediaries.

Criminals understand that startup founders are accustomed to taking calculated risks and may be more open to unconventional opportunities, especially during challenging fundraising periods or cash flow pressures. They present opportunities that seem aligned with typical startup networking and partnership development.

1. Professional money laundering organizations
   

Professional money laundering organizations function as full-service providers to other criminal organizations, offering sophisticated capabilities that target business operations. Their tactics include creating elaborate fake invoicing systems for services never rendered, recruiting legitimate-looking businesses as unwitting partners through seemingly normal business development activities, implementing complex layering schemes across multiple business accounts to obscure money trails, and exploiting international trade financing and B2B payment systems that have fewer individual oversight mechanisms.

1. Social engineering targeting leadership
   

Rather than focusing solely on financial processes, criminals increasingly target founders or finance team members personally. They spend months building relationships through industry events, social media, or professional networks before eventually requesting "business favors" involving company accounts.

This approach exploits the blurred personal and professional boundaries common in startup environments, where business relationships often develop into personal connections. The requests typically start small, perhaps asking to receive a payment for a "delayed wire transfer" - before escalating to larger amounts or more complex schemes.

1. Check fraud
   

While digital payments dominate startup operations, check fraud has evolved to specifically target business accounts. Criminals realize that business checks represent significantly higher dollar amounts than consumer checks and often involve accounts with higher balances and less frequent monitoring.

The process involves systematically stealing business mail, using chemical agents to "wash" the original information, and rewriting checks with new payee details and amounts. Business accounts become attractive targets because they typically maintain higher balances and may have less real-time monitoring than consumer accounts.

1. Cryptocurrency scams
   

Digital assets provide modern laundering pathways that appeal to criminals because they enable rapid cross-border movement of funds outside traditional banking monitoring systems. The conversion from traditional business payments to cryptocurrency helps obscure money trails and creates significant recovery challenges due to irreversible transactions.

Many legitimate businesses become unwitting conversion points in these schemes, receiving traditional payments that they're instructed to convert to cryptocurrency for seemingly legitimate business purposes like international supplier payments or investment opportunities.

Red flags that could save your startup millions

Warning signs often appear in combination rather than isolation. Train your entire finance team to recognize patterns rather than individual incidents, as it can significantly improve detection rates.

Email and communication irregularities

• Watch for subtle variations in familiar email addresses. Suppliers might become suppIiers with a capital I replacing the lowercase L.
  
• Grammar or language inconsistencies in vendor communications can indicate foreign criminals using translation software.
  
• Urgent requests that bypass normal approval workflows should trigger immediate verification, especially when they include instructions to keep transactions "confidential" or pressure to act immediately without standard verification procedures.
  

Unusual payment requests

• Be suspicious of sudden changes to vendor banking details without prior notice through normal communication channels.
  
• Requests to send payments to personal rather than business accounts are major red flags.
  
• Unusual payment methods or destinations for previously established relationships.
  
• Large overpayments followed by refund requests often indicate check fraud schemes.
  
• Instructions to split payments across multiple accounts can signal money laundering operations.
  

Suspicious account and transaction patterns

• Monitor for rapid money movement in and out of accounts, especially when transactions seem inconsistent with normal business operations.
  
• Multiple small transfers designed to avoid detection thresholds are telltale signs of systematic money laundering
  
• Cross-border transfers to high-risk jurisdictions immediately after receiving funds might suggest mule activity.
  
• ATM withdrawals shortly after large incoming transfers are also strong indicators of money mule operations.
  

Vendor and counterparty behavior changes

• Question vendors’ reluctance to verify changes through established communication channels. Legitimate service providers and vendors understand security concerns and readily cooperate with verification requests.
  
• Vague explanations for banking changes or payment urgency can suggest fraud
  
• New suppliers with minimal verification documentation or counterparties requesting unusual documentation or processes outside normal industry standards warrant additional scrutiny.
  

Internal team indicators

• Be aware of team members receiving unusual "business opportunities" that involve company financial processes. Personal financial pressure on staff with account access can create vulnerability to recruitment.
  
• Resistance to following established payment verification procedures might suggest your security protocols have been compromised.
  
• Unusual personal relationships between staff and vendors or financial partners should prompt additional oversight.
  

When in doubt, verify through independent channels. The few minutes spent confirming payment details can prevent months of legal, regulatory, and reputational consequences that can derail growth plans and damage investor confidence.

Prevention strategies that work against money mule fraud

Meeting compliance and regulatory obligations strengthens your fraud defenses while positioning your startup for sustainable growth. The most effective approaches integrate security seamlessly into business operations rather than creating friction.

Strong authentication and verification systems

Since MAS and HKMA require enhanced customer due diligence, proper identity verification becomes a business necessity rather than optional security measure. Implement multi-factor authentication for all financial transactions, especially international transfers, along with biometric verification where possible for high-value payments. Require multiple approvers for payments above defined thresholds and establish dual verification processes that confirm all banking detail changes through independent communication channels.

Platforms like Aspire integrate these verification steps seamlessly, meeting compliance requirements while minimising disruptions to your business operations.

Transaction monitoring and pattern recognition

Both Singapore and Hong Kong require monitoring for suspicious patterns and reporting unusual activity. Deploy real-time monitoring systems that flag unusual payment patterns, rapid fund movements, and transactions inconsistent with normal business operations. Set intelligent thresholds based on your specific business model. What's normal for a SaaS startup can differ from an e-commerce operation or manufacturing business.

Choose financial platforms like Aspire that provide built-in monitoring capabilities that meet regulatory standards and enable you to focus on scaling your business

Documentation and record keeping

All major jurisdictions require detailed records of transactions and verification procedures. Maintain updated records of all vendor banking details and authorized contact persons, document all verification steps taken for payment changes or new vendor relationships, and keep detailed records of any suspicious activity detected and actions taken.

Proper documentation proves good faith efforts and supports regulatory compliance, and also valuable for investor due diligence and partnership evaluations.

Team training and culture development

When developing training programs, include realistic scenarios specific to your business type and payment patterns. Create a culture where questioning unusual requests is valued rather than discouraged, and establish clear escalation procedures that remove pressure to process payments without proper verification.

Vendor management and due diligence

Implement robust vendor onboarding procedures with proper documentation and verification, conduct regular audits of vendor relationships and payment patterns, question new vendors or sudden changes in established relationships, and verify vendor details through independent sources rather than just provided documentation.

How AI and machine learning can level the playing field

The technology arms race between criminals and defenders increasingly favors organizations that properly implement modern detection and prevention systems. These tools democratize enterprise-level protection for growing businesses.

• Smarter detection through behavior patterns: Modern systems learn how normal customer activity looks and can spot unusual changes that may suggest suspicious use of an account
  
• Understanding hidden connections: Technology can uncover links between accounts, payments, and networks that fraudsters use to hide their activities
  
• Holistic monitoring across payments: By looking at transactions across different payment channels together, gaps are closed where criminals might otherwise slip through
  
• Staying one step ahead: With intelligence shared across the industry, fraud prevention tools evolve quickly, helping protect customers from new scams as they emerge
