1.6 Million People Impacted
What Happened?
Laboratory Services Cooperative (LSC), a nationwide provider of diagnostic and laboratory testing, suffered a major data breach that compromised the personal information of 1.6 million individuals. On October 27, 2024, LSC’s security team detected suspicious activity in its network.
LSC immediately brought in third-party cybersecurity experts to investigate the intrusion and notified federal law enforcement. Investigators discovered that an unauthorized party had infiltrated sections of LSC’s network and accessed—or removed—files containing highly sensitive data.
LSC partnered with a specialized vendor to identify which individuals the breach affected and what information the attackers accessed. By February 2025, the vendor confirmed that the breach exposed extensive personal, medical, insurance, and financial data.
What Information Did Hackers Steal?
According to LSC’s report to the Maine Attorney General’s Office, the stolen data includes one or more of the following:
Personal Information:
- Full names
- Social Security numbers
- Government-issued IDs (driver’s licenses, passports)
- Dates of birth
Medical Data:
- Service dates
- Diagnoses and treatments
- Lab test results
- Healthcare provider and facility names
Insurance Details:
- Plan types
- Insurance carrier information
- Member or group ID numbers
Financial and Billing Data:
- Medical billing records and claims
- Bank account numbers
- Credit and debit card details
Although LSC’s core laboratory systems remained functional, the breach exposed data that criminals can easily misuse for fraud, identity theft, and privacy violations.
How Could Criminals Use the Data?
Commit Medical Identity Theft:
Fraudsters could use stolen insurance details to receive care or file false claims.
Launch Phishing and Impersonation Scams:
Hackers can use personal and health details to send fake messages that impersonate healthcare providers or insurers.
Steal Money:
With access to bank or card data, attackers can conduct unauthorized transactions or sell the information online.
Target Individuals for Harassment or Profiling:
Bad actors may use demographic and medical data to dox or discriminate against individuals.
