Money mule detection: Understanding how mule networks operate

Guests: Hailey Windham and Karen Boyer

Today we are diving into a topic that sits right at the intersection of fraud, anti-money laundering, and financial crime investigations.

Money mules.

If you work in banking fraud or financial crime, you already know how central mule accounts have become to modern fraud schemes. Whether the fraud starts with phishing, account takeover, investment scams, or social engineering, the money almost always needs to move somewhere.

And that somewhere is often a mule account.

So for this episode, I’m sharing a Banking on Fraudology conversation where Hailey Windham sits down with Karen Boyer, SVP of Financial Crimes at M\&T Bank. Together they unpack the complicated ecosystem behind mule accounts, money movement, and the growing overlap between fraud and AML investigations.

Because understanding how mule networks operate is essential if financial institutions want to stop fraud before the money disappears.

And that challenge is getting harder.

Fraud rings are becoming more organized. Recruitment tactics are evolving. And generative AI is starting to influence the way criminals run phishing and social engineering campaigns.

Here is what money mule activity looks like in practice:

  • Fraud proceeds moving through mule accounts before reaching criminal networks
  • Social engineering mule recruitment targeting individuals online
  • Complex money movement patterns across multiple institutions
  • Increasing overlap between fraud detection and anti-money laundering investigations

What you’ll hear in this episode:

  • How money mule typologies help investigators identify suspicious accounts
  • Why money movement monitoring is critical to stopping fraud losses
  • How generative AI phishing risks may increase mule recruitment
  • Why fraud and AML convergence is changing how banks investigate fraud
  • How financial institutions collaborate to disrupt mule networks

You should listen to this episode if you:

  • Work in banking fraud detection or financial crimes prevention
  • Investigate suspicious money movement across accounts
  • Want better strategies for mule network detection
  • Care about AML and fraud collaboration inside financial institutions
  • Follow emerging fraud tactics and social engineering schemes

Episode notes & key takeaways

Why money mule detection is central to stopping fraud

Let’s break this down.

Most fraud schemes do not end with the initial attack. Whether criminals steal credentials, trick victims through scams, or exploit payment systems, the next step is moving the money.

That is where mule accounts come in.

Money mules allow fraud rings to move stolen funds through layers of accounts before the money ultimately reaches the criminals organizing the scheme.

And the faster those funds move, the harder it becomes for investigators to recover them.

  • Money mule detection focuses on identifying suspicious money movement
  • Mule network detection often involves analyzing patterns across multiple accounts
  • Account-to-account fraud monitoring helps identify mule activity earlier
  • Financial crimes prevention depends on stopping funds before they disappear

How mule recruitment is evolving

Another topic discussed in this episode is how criminals recruit money mules in the first place.

Recruitment tactics vary widely.

Some individuals are knowingly participating in fraud. Others believe they are participating in legitimate work opportunities or online financial services.

Social media, job boards, and messaging apps are common recruitment channels.

And increasingly, fraud rings are using social engineering tactics similar to those used in phishing scams.

  • Social engineering mule recruitment targets vulnerable individuals
  • Money mule typologies include both knowing and unknowing participants
  • Evolving mule tactics make detection more challenging
  • Fraud rings scale recruitment through online platforms

Why fraud and AML teams need closer collaboration

One of the biggest insights from this conversation is how much fraud investigations now overlap with anti-money laundering programs.

Historically, fraud and AML teams often worked separately.

Fraud teams focused on stopping fraudulent transactions. AML teams focused on monitoring suspicious financial activity and reporting potential money laundering.

But mule activity sits directly in the middle of both.

That is why collaboration between these teams is becoming increasingly important.

  • Fraud and AML convergence improves investigation outcomes
  • AML and fraud collaboration helps identify complex financial crime patterns
  • Suspicious money movement often requires cross-team analysis
  • Financial institution fraud controls benefit from shared intelligence

Why resource limitations make mule detection harder

Even when institutions understand the risks associated with mule networks, resource limitations can create challenges.

Fraud teams often face large volumes of alerts, limited investigative capacity, and constantly evolving attack patterns.

And mule networks are intentionally designed to make investigations more difficult.

Funds may move quickly across multiple institutions, jurisdictions, and payment methods.

Which means effective detection requires both strong technology and coordinated investigative work.

  • Fraud prevention resource constraints affect investigation capacity
  • Bank mule account investigations require specialized expertise
  • Money movement monitoring tools support investigative teams
  • Collaboration against money mules improves detection across institutions

The big takeaway from this episode is that money mule detection is not just an AML problem or a fraud problem.

It is both.

Stopping mule networks requires better visibility into money movement, stronger collaboration across financial crime teams, and a deeper understanding of how modern fraud operations actually function.

Because if fraudsters cannot move the money, the entire operation becomes much harder to sustain.
