A cybercriminal operating under the alias “Satanic” has reportedly orchestrated a significant data breach involving WooCommerce, a prevalent eCommerce platform. The breach is alleged to involve sensitive information from approximately 4.4 million users, potentially impacting notable entities including NVIDIA Corporation, Texas.gov, and the National Institute of Standards and Technology (NIST).
Satanic’s claims surfaced shortly after asserting responsibility for a separate breach tied to Magento. In a recent communication on Breach Forums, the hacker stated that the breach occurred on April 6, 2025, and involved the extraction of over 4.4 million records that comprise personal and corporate details.
While the hacker indicates that the data was not directly retrieved from WooCommerce’s core systems, it suggests a compromise of tools associated with websites utilizing the platform. This could potentially involve Customer Relationship Management (CRM) systems or marketing automation tools that rely on third-party integrations. The breach appears to encompass not only customer details but also company-specific insights, such as email addresses, phone numbers, physical addresses, and social media links tied to business metrics like sales figures and employee counts.
Satanic asserts that the compromised database includes more than 4.4 million individual records and around 1.3 million unique email addresses, as well as technical metadata outlining corporate websites’ technology stacks and payment solutions. A sample of the data purportedly reveals information from significant organizations, including nist.gov and texas.gov, along with major companies such as the New York City Department of Education and Oxford University Press.
Analysis of the released data indicates that it includes structured insights one would expect from a well-organized marketing database, featuring estimated revenue, SKU counts, hosting providers, and links to corporate social media accounts. Additionally, numerous entries reference WordPress content management systems, with WooCommerce identified as the eCommerce plugin. Other integrations spotted include Salesforce, Pardot, and various payment platforms.
Currently, the hacker is marketing the stolen database via direct messages or Telegram, inviting offers but not providing a specific price tag. This action continues a pattern for Satanic, who has admitted to previous breaches, including a significant incident affecting 1.4 million users related to another platform, Tracelo. Recently, this individual also claimed responsibility for breaching Twilio’s SendGrid, a contention that was staunchly denied by the company.
If verified, this WooCommerce-related breach would mark one of the largest exposures involving WordPress-based eCommerce platforms this year. The combination of personal data, business insights, and technological profiles presents a lucrative resource for cyber adversaries involved in phishing, social engineering, and competitive intelligence activities.
As of now, WooCommerce has not issued a public response regarding these claims. It is crucial for businesses that leverage WooCommerce and associated CRM or marketing tools to reassess their third-party integrations and monitor for any indicators of unusual data access. The implications of such breaches extend beyond immediate damages, often leading to significant reputational harm and regulatory scrutiny.
In analyzing the incident through the lens of the MITRE ATT&CK framework, tactics such as initial access, exploitation of third-party services, and perhaps even privilege escalation may have facilitated the breach. This incident serves as a stark reminder of the vulnerabilities inherent in interconnected systems and highlights the ongoing challenges businesses face in protecting sensitive information in a complex cyber landscape.
