Handling 100’s of fraudulent orders

↑ Back to top

You may have installed our plugin as you’ve been hit with hundreds of fraudulent orders.

It can be a shock to start your day handling issues such as hundreds of fake, fraudulent orders from overnight, which can often result in flow on effects. These may include your bank or 3rd party merchant banking provider suspending your account or sending you a large bill.
We refer to this sort of activity as a velocity attack. It is quite common but easily resolved in most cases.

Preventing Velocity Attacks with this plugin

↑ Back to top
Normally we can block these attacks by configuring the plugin appropriately. The main setting you need to configure in the plugin is the reCaptcha tool. Configuring reCaptcha within the Anti-Fraud plugin removes the ability of a fraudster to commit mass credit card fraud. This is the easiest way to prevent this fraud, however it is not always effective.

The plugin is not stopping Velocity Attacks!

↑ Back to top

The plugin is effective at stopping velocity attacks. But this is not the case when there is another problem on your site that is rendering it ineffective. A good analogy here is, imagine you have decided to increase security on your house by installing a deadlock on the door. You then leave home, but leaving the back door wide open. While there is increased security on the front door, it is only as effective as the weakest point in your home security.

To sum this up, where reCaptcha has been set up within our plugin, and the issue persists, it indicates one or more of the following:

-Your site has a general security vulnerability – such as non secure hosting.
-A plugin on your website has a security vulnerability.
-Your website has been hacked and is infected with malware.

Where this is the case, the plugin will not work effectively and you will continue to experience problems.

Next steps

OPMC works with both non technical ecommerce store owners, as well as developers and agency partners who are not specialised in security, to solve these issues.

We are therefore experienced in handling these various scenarios quickly and cost effectively. Please contact us through WooCommerce.com Support selecting this plugin and we can provide prompt expert advice to resolve this matter.

Usage

↑ Back to top

WooCommerce Anti-Fraud checks for possible fraud whenever an order is placed. The outcome of this check is the output of Risk Advise and Risk Score.

For Risk Advise:

  • Low Risk – A Risk score lower than 25.
  • Medium Risk – A Risk score between 25 and 75.
  • High Risk – A Risk score higher than 75.

Risk Advise, Risk Score and a list of failed rules are added to the order edit display.

The Fraud Risk meta box

Risk Advise is also shown in the order overview screen as a colored shield, and the shield color is based on the level of Risk Advise.

Order overview

Risk Advise color key:

  • Green – Low Risk
  • Orange – Medium Risk
  • Red – High Risk
  • Grey – No fraud check is done

How are Fraud Advise and Fraud Score calculated?

↑ Back to top

We created a set of rules that vary from simple checking if the shipping address matches the billing address to advanced rules such as proxy detection. We calculate a score based on the number of rules the order fails, then display Fraud Advise based on this score.

Configuring the plugin’s settings

↑ Back to top

By navigating to WooCommerce > Settings and clicking the Anti-Fraud tab, you can configure how the plugin reacts to different risk scores.

  • Admin Email Settings – Leave this on if you want WordPress to send you emails regarding the outcome of anti-fraud checks.
  • Cancel score – This field allows you to determine when orders are automatically cancelled according to the score of their anti-fraud check. Orders with a risk score equal to or higher than the value entered will automatically be cancelled. By writing “0” in the field, this feature will be disabled and no orders will automatically be cancelled.
  • On-hold score – This field is used to determine when an order is automatically put on hold. When an order’s risk score equals or exceeds this value, it will be placed on hold to be reviewed. By writing “0” in the field, this feature will be disabled and no orders will automatically be put on hold.
  • Email notification score – Risk scores that meet or exceed this value will cause an email to be sent to your address.
  • Medium and high-risk thresholds – This field allows you to change what the plugin classifies as a medium-level risk or a high-level risk.
  • Enable first-order check – When enabled, the plugin will include a warning if the order placed is a user’s first order. The risk score will also be affected according to the rule’s risk weight.
  • Enable first-order check for processing order – When the first-order is placed by a new client and the order enters into processing mode because of the low risk involved, enabling this field will reinitiate our anti-fraud algorithm for giving you an extra layer of protection. 
  • Enable international order check – This setting checks if an order has been placed internationally. If it is, a warning is displayed and the risk score will be affected according to the rule’s weight.
  • Enable IP geolocation check – When enabled, the plugin will look up the IP address of customers to determine their location. This information can help you detect illegitimate orders (eg. the IP location is in a different country to the shipping address).
  • Enable Billing and Shipping address check – Enabling Billing and shipping address check will trigger this feature when there is a conflict between billing and shipping address. 
  • Enable Proxy check If a buyer is using a proxy to buy from your store, the antifraud plugin will add score set for this feature to other indicators when enabled.
  • Enable suspicious domains check – By entering email domains (eg gmail.com, yahoo.com) into the “Suspicious Domains” field, the plugin can warn you when an order is placed using one of these addresses.
  • Enable unsafe countries check – Countries marked on this list are considered suspicious by the plugin. You can select multiple countries by holding CTRL (Windows) or  ⌘ (Mac) when you are clicking them.
  • Enable order amount check – Unusually large orders are a common sign of fake transactions. By enabling this setting, you will be warned when an order is placed that exceeds the cost in the “Amount limit” box.
  • Check for attempt count – Enable this setting to check for multiple orders placed over short time spans (eg. 3 orders over 24 hours.
  • IP multiple details check – When enabled, this setting will check if multiple orders have been placed over the same IP address. This is helpful for detecting users who are attempting to purchase with several different emails.

Blacklist Settings

↑ Back to top

By adding an email to your blacklist, their purchases will automatically be detected as a high-risk.

By enabling automatic blacklisting, email addresses with a high risk of fraud will be added to this list automatically. You can also block individual email addresses by adding them to the list manually. Use this feature for fraudulent customers who you’ve had trouble with in the past.

Paypal Settings

↑ Back to top
  • Enable PayPal verification – When this setting is active, all PayPal payments will require verification. A verified PayPal email address is linked with more legitimate, low-risk orders. If verification fails, the order is put on hold.
  • Prevent downloads if verification fails – For WooCommerce stores which have digital downloads, this setting can be used to restrict access to the downloadable file(s) until the PayPal email is verified.
  • Time spend before further attempts – This setting adjusts how many days are allowed to pass before another email is sent.
  • Email body – This field allows you to customize the message that is sent to customers who need to verify their PayPal accounts.

Rule settings of minFraud®

↑ Back to top

By default Minimum MinFraud Risk Score for minFraud® integration is set to 30. It is the threshold value after which the minFraud alert is triggered in the WooCommerce antifraud plugin. Similarly, the default value of MinFraud Rule Weight is also set to 30, which is the weighting in proportion to the total per cent of fraud set for the minFraud. 

You can also customise your setting how it suits you. For example, you want minFraud to trigger when you get a score of 50, you have to set Minimum minFraud Risk Score to 50. Similarly, if you want to give minFraud more weighting, for example, 40 on Fraud risk graph that is displayed in your order then set MinFraud Rule Weight to 40.


minFraud integration is inactive by default. You have to set it after activating the plugin following the procedure mentioned above.
