Fighting Back Against Tech-Savvy FraudstersStaying a step ahead requires moving beyond the security techniques of the past.
It seems that a new fraud scheme emerges every day. And with billions of compromised credentials, criminals have been implementing a high volume of fraud attacks on organizations across all industries.
The latest fraud scheme — known as credential stuffing — involves criminals who have access to advanced systems and technology using the stolen credentials to log in to online accounts. While credential stuffing has been around for a few years, the current iteration of the scheme is so advanced that criminals can make login requests appear to come from different IP addresses and different browsers. This helps bypass fraud prevention defenses that recognize multiple attempts from a single IP address.
But beyond the technological advances that criminals leverage, the challenge for most organizations is the tendency for people to reuse usernames and passwords across multiple sites. That means the credentials that were stolen may not have originated from the affected organization. And according to Experian's "2019 Global Identity & Fraud Report," more than two in five consumers worldwide have already experienced a fraudulent event online at some point in their lives. To make matters worse, organizations still heavily rely on usernames and passwords as the primary security method — confirmed by the report, which showed passwords, PIN codes, and security questions remain the most widely used authentication methods by businesses.
While organizations can take the steps to educate consumers on best practices for online security and passwords, there needs to be more proactive measures to protect people's accounts and information. If not, the risk of account takeover fraud could increase exponentially — especially with the prevalence among consumers to use mobile devices to access online accounts. According to Javelin Strategy & Research's "2019 Identity Fraud Study," in 2018, 17% of account takeover victims had their mobile phone account compromised, compared with 10% in 2017.
As increasing numbers of people use smartphones and tablets for financial transactions and email, organizations must explore heightened fraud prevention measures, such as advanced device intelligence. The use of device characteristics needs to be more sophisticated than the traditional collection of high-level attributes like browser type, operating system version, and IP address. These characteristics are often easy to spoof, enabling criminals to mask the origin of the login request.
For example, if most credentials are being used from a specific geolocation — particularly one that has been used in previous attacks — it could indicate fraudulent behavior. But businesses can also analyze the velocity at which the information and device is being used — criminals tend to reuse data and access multiple accounts from the same device at a high volume within a short period of time.
Device intelligence is only one component of a successful fraud prevention and identity management strategy. The combination of device identification technology with advanced analytics, such as biometrics, machine learning, digital tokenization, and document verification can help an organization uncover anomalies that may indicate fraudulent behavior. But more importantly, these advanced measures protect people's information while requiring little effort on behalf of the consumer.
The earlier in the process that an organization can detect fraud, the more damage to a customer's account and identity it can prevent. And that means a happy, loyal customer.
Criminals will always look to exploit weaknesses and vulnerabilities within an organization's systems; however, technology and advanced analytics can help businesses counteract the threat. There is no silver bullet for fraud prevention, but there are multiple approaches that help businesses make the right fraud decisions and protect people's identities.
