Published
- Older breach: BCNYS disclosed being hit by a significant cybersecurity incident in February 2025.
- What leaked: Full names, Social Security numbers, dates of birth, and financial details are among the possibly exposed details.
- Breach impact: This is one of the most substantial data exposures affecting New York's business community this year.
The Business Council of New York State (BCNYS) has disclosed a significant cybersecurity incident that occurred in February 2025 and compromised the personal, financial, and medical information of 47,329 individuals.
Timeline and Discovery of the BCNYS Cybersecurity Incident
Threat actors maintained unauthorized access to BCNYS internal systems between February 24 and February 25, 2025. However, the organization did not detect the intrusion until August 4—nearly six months after the initial compromise.Â
This extended dwell time allowed attackers substantial opportunity to exfiltrate sensitive organizational data before detection.
Following the discovery, BCNYS immediately initiated an investigation, which revealed that attackers successfully accessed and extracted files containing highly sensitive personal data exposure across multiple categories.
Scope of Compromised Information
The Business Council of New York State data breach exposed extensive personally identifiable information (PII) and protected health information (PHI). Compromised data elements include:
- full names
- Social Security numbers (SSNs)
- dates of birth
- state identification numbers
- comprehensive financial account details including:
- institution names
- account numbers
- routing numbers
- payment card information with associated PINs and expiration dates
Additionally, the data breach exposed sensitive medical information encompassing healthcare provider details, diagnostic information, prescription data, treatment procedures, and health insurance particulars, according to the BCNYS notice.Â
The breadth of exposed data categories significantly amplifies potential identity theft and financial fraud risks for affected individuals.
Organizational Profile and Impact Assessment
BCNYS operates as New York State's largest statewide employer association, representing over 3,000 member organizations, including chambers of commerce, professional associations, trade groups, and major multinational corporations.Â
These member organizations collectively employ more than 1.2 million New Yorkers, making this incident's potential ripple effects considerable.
Data Breach Response and Mitigation Measures
BCNYS has implemented comprehensive data breach response protocols, including free credit monitoring services for individuals whose SSNs were compromised. The organization has issued formal breach notifications to affected parties and regulatory authorities, including filing with Maine's attorney general.
The organization maintains that current investigations have yielded no evidence of fraudulent activity or identity theft related to this incident.
Recently, Social Security Numbers and more were exposed to hackers in the Allianz Life data breach.
