Washington: The cyberattack on backend service provider Conduent Inc. continues to grow in scale, with the number of affected individuals now exceeding 25 million, up from an earlier estimate of about 10.5 million. Security analysts say the incident is among the largest third-party data breaches reported in recent years.
Investigations indicate that attackers remained inside the company’s network for nearly three months and were able to exfiltrate approximately 8 terabytes of sensitive data. The responsibility for the attack has been claimed by SafePay ransomware gang, though cybersecurity agencies are still verifying the authenticity of the claim and examining the technical evidence.
Scope of the Data Exposure
The stolen information reportedly goes far beyond basic contact details. Notification letters and regulatory disclosures suggest that the compromised data may include full legal names, residential addresses, dates of birth, Social Security numbers, and health-insurance-related records. Experts warn that such permanent identifiers could be exploited for identity theft, financial fraud, and highly targeted phishing operations for many years.
Initial government filings had estimated about 10.5 million victims, but the figure increased sharply as individual states and corporate clients completed internal assessments. In the state of Texas, about 15.4 million residents are now believed to be affected, while Oregon continues to report roughly 10.5 million impacted individuals.

Third-Party Vulnerability and Systemic Risk
Security researchers say the case underscores the growing vulnerability associated with third-party service providers. Many government agencies and private organizations depend on external platforms for administrative, healthcare claim, and payment-processing operations. Such outsourcing arrangements can create a security blind spot because breach activity may not appear in the client organization’s own monitoring systems. In many cases, affected users learn about the exposure only after receiving a breach notification letter.
The infrastructure of Conduent Inc. is widely used to support public benefit programs across multiple US states, including Medicaid, SNAP food assistance programs, and healthcare claims management. Back-office human resource and payroll-related services for large corporate employers are also handled through the platform. As a result, many people whose data was exposed were never direct customers of the company but had their information processed through its systems.
Cybersecurity experts have emphasized that the leakage of permanent identity markers such as Social Security numbers and medical records poses particularly long-term risks because such information cannot be changed once compromised. Unlike passwords or temporary authentication credentials, these identifiers may remain valuable to cybercriminals for years.
Long-Term Consequences and Response Measures
Authorities have advised individuals who receive breach notification letters to immediately monitor their bank accounts, change passwords for online services, and review credit reports for suspicious transactions. Users are also warned to avoid clicking links in unsolicited emails or messages that may be associated with phishing attempts.
The incident highlights the increasingly interconnected nature of modern digital ecosystems, where cybersecurity responsibility extends beyond a single organization. When data processing functions are outsourced to third-party vendors, the potential attack surface expands across multiple institutions and user groups. Security analysts believe that third-party cybersecurity auditing and compliance requirements will likely become much stricter in the coming years.
Investigators are still working to determine which technical vulnerability was exploited by the attackers and how the stolen information may be monetized or used in future criminal campaigns. Meanwhile, concerns persist that the personal data of millions of individuals could remain at risk of long-term cyber exploitation.
