Cyber Incident Victim: NutriBullet
Date:
Feb 2020
Location:
United States of America
Summary
The NutriBullet website was compromised by Magecart Group 8, which injected malicious skimming code to steal customer payment card information during online transactions. Attackers repeatedly deployed new skimmers targeting jQuery libraries and site scripts after initial takedowns, exfiltrating data to changing command-and-control servers. The breach exposed financial details submitted through checkout pages, risking fraudulent use. The company removed the malicious code, initiated forensic investigations, and implemented enhanced security measures including multi-factor authentication to prevent future intrusions.

Description
The NutriBullet website experienced multiple Magecart skimming attacks between February 20 and March 17, 2020. RiskIQ researchers identified the first skimmer on February 20, attributing it to Magecart Group 8, a collective specializing in JavaScript-based payment card theft. Attackers injected malicious code into a jQuery JavaScript library used across all NutriBullet pages, appending it at the library's bottom to capture customer payment details during online transactions. This stolen data was exfiltrated to a command-and-control (C2) server controlled by the attackers. The initial skimmer was removed by March 1, but a second variant appeared on March 6, targeting a separate jQuery submodule resource. A third skimmer emerged on March 10, injected at the top of another site script named main-build-8a9adc31.js. RiskIQ collaborated with AbuseCH and ShadowServer to disrupt the C2 infrastructure after each iteration, though attackers persistently deployed replacement servers.
The skimming code matched samples previously linked to Magecart Group 8’s 2019 compromises of Amerisleep and MyPillow, affecting over 200 domains historically. NutriBullet’s IT team fully removed the malicious code by March 17 after external disclosure, initiating forensic investigations and updating security protocols. The company implemented Multi-Factor Authentication (MFA) for credential access and reinforced security policies. No customer data breach scope was quantified publicly, but the repeated skimmer deployments exposed payment card information submitted during the attack window. RiskIQ emphasized that takedowns of external malicious domains alone were insufficient to prevent recurrence due to unresolved website vulnerabilities enabling payload redeployment.
