The victim count in the 2024 hack on Conduent Business Services just ballooned again, with the Xerox-spinoff now telling Wisconsin regulators the incident affected “25 million-plus” people nationwide.

Florham, New Jersey-based Conduent previously told Texas regulators the incident affected about 15.5 million Texans, including about 4 million Blue Cross Blue Shield of Texas members (see: Texas AG Investigating Conduent, BCBS Texas Hack).
That prompted Texas attorney general Ken Paxton earlier this month to announce that his office had launched an investigation into the Conduent hack, which he called “likely the largest breach in U.S. history.” (See: Conduent Hack Victim Count Soars by at Least 50%).
In reality, even with 25 million people affected so far by the Conduent hack, the incident is a long way from being the largest U.S. data breach.
UnitedHealth Group’s IT services unit Change Healthcare currently holds the data breach record with 193 million people affected by the company’s 2024 Alphv/BlackCat ransomware attack.
Paxton was also at least the second state attorney general to publicly announce an investigation into the Conduent hack. Montana’s attorney general last October also launched an investigation into the incident, which affected about 462,000 Blue Cross Blue Shield of Montana plan members (see: Montana Officials Looking into BCBS Breach Tied to Vendor).
Other Conduent health insurance clients affected by the hack include Premera Blue Cross and Humana. Earlier this month, Volvo also disclosed that the personal and health plan information of about 17,000 employees and affiliated people were affected by the Conduent hack.
Darkweb monitoring platform Ransomware.live found that ransomware gang SafePay listed Conduent on its darkweb leak site in February 2025 as one of its victims, threatening to publish 8.5 terabytes of the company’s stolen data.
Conduent in April 2025 first publicly disclosed the hack in a filing to the U.S. Securities and Exchange Commission.
The back-office support services vendor said it discovered the incident on Jan. 13, 2025. The company’s investigation found that hackers broke into Conduent servers from Oct. 21, 2024, to Jan. 13, 2025.
Information compromised in the incident potentially includes individuals’ names, addresses, dates of birth, Social Security numbers, health insurance details and medical information.
Conduent declined Information Security Media Group’s request for additional details about the incident and for comment on the latest increase in its breach victim count.
