Examining Transaction Laundering Tactics Commonly Used by Scammers

There are multiple methods a fraudster can employ to engage in transaction laundering. In some cases, the fraudsters might impersonate a merchant to conduct the fraud themselves.

Transaction Laundering

Transaction laundering is a serious matter for eCommerce. With the right strategies in place, though, merchants can protect their businesses, prevent loss, and preserve their relationships with financial institutions. But what do you need to know to protect your business?

A legitimate merchant may not know their site is being used, or they may be acting in coordination with a second-party fraudster. To illustrate, let’s take a look at a few ways in which online sellers can get caught up in these schemes:

Account Compromise 

By gaining access to a merchant’s account information, criminals can leverage the data to take over the account and run bad transactions through the merchant’s account.

Affiliate Fraud

The criminal runs transactions by using stolen cardholder information. They profit off of unearned commissions, and leave the merchant to deal with the legal fallout.

Corrupt Merchants

The merchant knowingly participates in criminal activity, often in collusion with other fraudulent entities or networks. They blend genuine transactions with illicit ones to evade detection.

Framing

Bad actors intentionally set up a legitimate merchant to make it appear as if they're partaking in illicit activities. This could lead to legal consequences for the innocent merchant.

Funneling

Fraudsters use a merchant’s account to deposit illegal funds and then withdraw the money immediately from a different geographic location. 

High-Value Assets

Criminals often use funds procured illegally to buy assets that retain value and are easily traded (metals, real estate, or artwork,etc.). By reselling these assets, they can then present their profits as lawful earnings.

Mimicry

Fraudsters mirror legitimate transactions by imitating the transactional behavior of authentic merchants, making it difficult to discern between genuine and fraudulent activities.

Shell Companies

Scammers create seemingly legitimate businesses to process illicit transactions under the guise of a genuine enterprise. They then use the account to camouflage the unauthorized activities.

Smurfing

With smurfing, large sums of money are divided into smaller portions, often below regulatory reporting thresholds, and distributed across numerous accounts using fake eCommerce transactions.

This is not an exhaustive list; just some of the most common tactics. Fraudsters can also engage in “pass-through” attacks, for instance, in which they embed a payment link in an illegal site. Or, they might set up a completely fake eCommerce site that they can use as a front operation. These may also be examples of transaction laundering.

Avoid becoming a pass-through for scammers with end-to-end fraud and chargeback protection.

Why is Transaction Laundering so Hard to Detect?

Transaction laundering is notoriously difficult to detect for several reasons. The sophistication of techniques employed, the use of technology, and the inherent nature of online commerce are all factors. Here are some of the primary reasons why detecting transaction laundering poses significant challenges:

Fraudsters often mix illicit transactions with genuine ones, making them difficult to distinguish. By processing a small volume of illicit transactions alongside legitimate ones, they can avoid raising any immediate red flags.

As detection methods improve, criminals adapt by devising new methods and tactics. This constant evolution means that traditional detection methods often lag behind the latest laundering techniques.

The digital marketplace has a vast number of interconnected platforms, payment processors, and merchant accounts. This complexity provides ample opportunities for fraudsters to find weak points and exploit them.

Fraudsters use advanced technologies, including automated bots and machine learning, to mimic legitimate user behaviors and transaction patterns. This further obscures illicit activities.

Money launderers can distribute illicit transactions across multiple payment processors and gateways. This reduces the likelihood of any single processor detecting an unusual volume or pattern of activity.

The global nature of online commerce means that transactions have many layers of geographic separation. Fraudsters can initiate transactions from one location, process them through a merchant or gateway in a second location, and then funnel the funds to a third location.

Some fraudsters operate with the knowledge that they may be detected eventually. As a result, they set up operations that are intended to be short-lived, extracting as much value as possible before shutting down and moving on.

Some merchants or payment processors, fearing reputational damage or regulatory consequences, might be hesitant to report suspicious activities, allowing transaction laundering to persist.
