What are the main e-Commerce frauds targeting online stores?

Three challenges in eCommerce Fraud Protection

One of my side hustles is lecturing postgraduate university students on financial crime intelligence – this is all about how to identify and detect fraud and illicit activity in your data. I regularly tell my students (and clients) that fraud is really a ‘process-based crime’ – it arises because of internal control gaps in your business processes which equate to vulnerabilities for your business, and opportunities for fraudsters and criminals.

Different types of fraud arise at different points in the eCommerce process. Every fraud scheme has its own unique characteristics, which means we can prevent and detect it! From my perspective, there are three challenges in eCommerce fraud protection:

  1. Detecting customer profiles or transactions which are highly likely to be fraudulent with a low false positive rate (see here for explanation); and,
  2. Detecting the fraud in time to avoid incurring a loss (this is particularly hard with realtime payments, outourced and / or automated fulfilment); and,
  3. Striking the right balance between enough loss prevention measures to mitigate the risk (your ‘risk appetite’) and too many controls (which makes for a bad customer experience, impacting sales conversions and customer retention).

To illustrate this for eCommerce, I have used the four-phased eCommerce marketing lifecycle promoted by SmartInsights.com and overlaid where different fraud schemes can arise:

Three categories of eCommerce fraud schemes

Let’s deep dive into the three main eCommerce fraud schemes:

Account related frauds

Some eCommerce fraud schemes revolve around a users identity or account. Examples of ways in which this may happen, either at account creation or account login include:

  • Phishing – social engineering attempts to compromise users and their accounts
  • Credential stuffing – attempts to use credentials stolen from another breach to login
  • Account takeover – where a user’s account credentials or browser session is hijacked
  • Identity theft – a victim’s identity is stolen and used to obtain loans, goods, etc.

Payment Frauds

The second category of eCommerce frauds revolves around the payment or transaction itself, including:

  • Use of stolen / purchased credit card details
  • Card testing – where criminals place small charges on a card to see if it is valid which could be disputed by the cardholder
  • Chargeback fraud – shopper makes a purchase on their own card, then requests a chargeback after receiving the goods
  • Refund Scams – shopper purchases something and ask for a refund before the product is delivered
  • Payment frauds – including card present and card not present transactions

Loss Prevention

The final category of eCommerce frauds is perpetrated by a user post-payment. Common fraud typologies include:

  • Change of address scams – delivery address is changed after payment but before shipping so goods are not sent to cardholders residence
  • Returns fraud – consumer receives goods, uses it, and sends it back (effectively ‘renting’)
  • Product diversion – where goods are basically stolen by trusted insiders (employers, contractors, suppliers)

Did you know that organised fraud, product diverters and shoplifting rings typically target specific products over others?

Products that are CRAVED are at greatest risk.

I have provided more information on which products are most likely to be targeted by organised fraud, product diversion and shoplifting rings in my article “product security risk assessments for tangible goods”.

Identifying your core business activities, systems and processes is key to understanding and managing your risk profile. I will review how to do this in a future article, but if you are looking for somewhere to start try www.juliantalbot.com and this article on ‘risk appetite and risk tolerance‘.
