Retailer Client Challenge
In early 2018, one of the world’s largest retailers identified they were being frequently targeted by credential stuffing attacks.
Threat actors utilised breached usernames and passwords to access customer accounts and make fraudulent purchases to the tune of millions of pounds per month, before selling the validated account details on the Dark Web.
The fraudulent activity not only cost the retailer directly but put the brand’s reputation at risk. Customers were continually locked out of accounts, asked to verify their legitimacy or required to reset their usernames and passwords following an attack, leaving many users feeling frustrated and vulnerable.
Threat actors typically used a combination of volumetric and sophisticated low and slow attacks to carry out the credential stuffing activity. The attackers were able to bypass the protection put in place by the retailer’s existing WAF and DDoS vendor and manual, reactive mitigation measures were required by the business’s Security Operations Centre (SOC) team; putting strain on internal resources.
“We had a team of ten people who were manually blocking I.P addresses and user agents of credential stuffing attacks, that could occur at any time. We had to make the business-critical decision to move to a proactive approach and improve our security” – Security Operations Manager
The retailer needed a specialist bot management vendor that could provide rapid detection and mitigation, using technology that would integrate with existing architecture. This would ensure the business acquired comprehensive visibility of all website, mobile app and API traffic.
The Solution: Netacea
Netacea’s industry-leading bot management solution accurately identified several credential stuffing attacks within 24 hours of implementation. Over the course of the next 30 days, Netacea detected large volumetric credential stuffing attacks and highlighted continued low and slow attacks, that were flying under the existing vendor’s radar.
Protecting The User Experience
The retailer must be able to facilitate more than 100,000 customer logins every hour, via a quick to load login page that presents minimal user friction. Working with Netacea enables the retailer to proactively protect customer accounts across the entire estate, without adding any latency or friction to the customer journey.
Netacea’s detection technology is integrated directly with the retailer’s SIEM solution to capture visitor data. This enables Netacea to quickly and effectively send recommendations to the login page while ensuring owners of breached accounts are made aware of the need to reset usernames and passwords.
The retailer is now protected from both volumetric and low and slow credential stuffing attacks, freeing up their SOC team to focus on new and emerging threats.
