6 steps to help prevent fraudulent payments.
How fraudsters operate.
Before we talk about what you can do to minimise your risk, it's helpful to understand common tactics fraudsters use. Online fraudsters usually use two methods
to steal money:
- Account takeover: You probably provide customers with accounts that store personal information, financial information, and purchase history. Fraudsters often hack into these accounts through phishing schemes. In one of the most common schemes, fraudsters send emails to trick customers into revealing usernames and passwords. The fraudsters then log in to your customers' accounts, change the passwords and make unauthorised purchases.
- Identity theft: Although most businesses take many precautions to secure customer data, fraudsters still manage to hack into databases and steal usernames, passwords, credit card numbers and personal information.
Managing your risk.
Although the potential for fraud is high in online transactions, it doesn't mean you must accept it as part of doing business online. By putting the right tools and processes in place, you can help keep your business and your customers secure and reduce your chances of drowning in chargeback fees and lost revenues. Below are 6 tips to help you get started. Once you've checked these off, be sure to review the 13 signs of unusual buyer activity
1. Monitor transactions and reconcile your bank accounts daily.
Nobody knows your business as well as you do. You know your biggest spenders and their buying patterns. Monitor your accounts and transactions looking for any red flags, such as inconsistent billing and shipping information, as well as the physical location of your customers there are tools that trace customers' IP addresses and alert you to those from countries known as a base for fraudsters.
Also, check to see if your customers are using free or anonymous email addresses (such as Gmail or Yahoo email addresses), as there's a much higher incidence of fraud coming from free email service providers than from paid.
2. Consider setting limits.
Using your unique knowledge of your business, set limits for the number of purchases and total value you'll accept from one account in a single day. It can help keep your exposure to a minimum should fraud occur.
3. Implement 3D Secure (3DS) for strong customer authentication (SCA).
The new PSD2 regulations come into force in March 2021, but you can improve your security by implementing them now. PSD2 regulates payment services and includes new security requirements for electronic payments to reduce fraud.
From March 2021, your payment solution will need to authenticate customers using strong customer authentication (SCA). If not, customer payments may be rejected by
the card issuer (e.g. the customer's bank). The protocol the card industry uses for authentication is called 3-D Secure (3DS). Get safe and get ahead by implementing 3DS, now. Learn more on our PSD2 site, here.
4. Use the address verification system (AVS) and card verification value (CVV).
These are now standard options from most payment providers but it's usually up to the merchant to switch them on. AVS compares the address given by the buyer with the card issuer's records. CVV (sometimes called CV2) is the three-digit or four-digit security code printed on credit cards. Again, this is compared with the card issuer's records to minimise fraud. Be sure you use both.
5. Get tougher with password requirements.
Hackers employ sophisticated programs that can run through all the permutations of a password. It won't take them long to crack a four digit, alpha-numeric password (such as, abcd"). The National Cyber Security Centre and Metropolitan Police recommend making passwords as long as possible by starting with three random words (e.g. fishboattulip"), then including capitalised letters, numbers, symbols and punctuation marks.2
Your customers may grumble as you enforce harder to crack passwords, but it's better safe than hacked.
6. Keep your platforms and software up to date.
Make sure you're running the latest version of your operating system (OS) and applications. Providers continually update their software with security patches to protect you from newly discovered vulnerabilities, as well as the latest viruses and malware. Likewise, install and regularly update business-grade anti-malware and anti-spyware software to prevent attacks that exploit outdated software vulnerabilities. Free, limited-feature, and consumer-strength anti-virus software are not sufficient.
Note: If your site is hosted on a managed solution, such as BigCommerce, automatic security patches help ensure that any vulnerabilities are quickly resolved.
