A misconfigured Amazon S3 bucket exposed over 86,000 medical records and personally identifiable information (PII) belonging to users of the nurse staffing platform eShift. The exposed data included names, addresses, phone numbers, email addresses, Social Security numbers, medical licenses, certifications, and vaccination records. This data breach highlights the continued risk of unsecured cloud storage and the potential consequences for sensitive personal information. eShift, dubbed the "Uber for nurses," provides on-demand healthcare staffing solutions. While the company has since secured the bucket, the extent of the damage and potential for identity theft and fraud remains a serious concern.
A significant data breach impacting over 86,000 individuals associated with the healthcare staffing platform eShift, often referred to as the "Uber for nurses," has been uncovered and detailed in a report by Website Planet. This security lapse stemmed from a misconfigured Amazon S3 bucket, inadvertently left open to public access without any protective measures like password authentication or IP restrictions. This vulnerability exposed a massive trove of sensitive Personally Identifiable Information (PII) and Protected Health Information (PHI), raising serious concerns about privacy violations and potential identity theft.
The exposed data encompassed a broad range of highly sensitive information belonging to both nurses and healthcare facilities using the eShift platform. For nurses, this included full names, home addresses, phone numbers, email addresses, dates of birth, Social Security Numbers (SSNs), driver’s license details including images, employment histories, professional license numbers, and even details about their immigration status (visas and work permits). In some instances, passport details were also exposed. The breach also impacted healthcare facilities, revealing their names, addresses, and tax identification numbers (EINs). Furthermore, the exposed data included signed contracts between eShift, nurses, and healthcare facilities, potentially revealing sensitive contractual agreements and financial details.
The security flaw existed for an indeterminate amount of time, allowing unrestricted access to this vulnerable data. Website Planet researchers discovered the exposed S3 bucket on February 1, 2024, and promptly notified eShift of the vulnerability on February 6, 2024. eShift acknowledged the issue and secured the bucket on February 12, 2024, six days after being notified. The length of time the bucket remained open before its discovery remains unknown, meaning the data could have been accessed by malicious actors for an extended period.
The implications of this breach are far-reaching. The exposed PII and PHI place affected individuals at considerable risk of identity theft, financial fraud, and other forms of malicious exploitation. The compromised data could be leveraged for targeted phishing attacks, fraudulent account creation, and even medical identity theft, allowing unauthorized access to medical services and potentially jeopardizing medical records. The incident also raises concerns about eShift’s security practices and their compliance with HIPAA regulations designed to protect the privacy and security of patient health information. This significant breach underscores the crucial need for robust data security measures, particularly for platforms handling sensitive personal and health-related information.
