Timeline: Breach (2015-09-16) · Indexed (Dec 01, 2024) · Year (2015)
Exposure: 110.2M records · 14 fields: Credit Status, Date of Birth, Email Address, Ethnicity or Race, Family Structure, Financial Profile, Full Name, Gender, Homeownership Status, IP Address, Phone Number, Physical Address, Purchase Preferences, Religion
Status: Unverified
Executive Summary
A large dataset of about 110 million records attributed to Experian and dated to around 2015 circulated online, containing names, email and physical addresses, dates of birth, and various other personal attributes. Multiple HIBP subscribers verified portions as accurate, but the source could not be conclusively established, so HIBP lists it as unverified. This is distinct from the separately confirmed September 2015 Experian/T-Mobile breach (about 15 million credit applicants, which exposed SSNs, drivers license and passport IDs).
ObscureIQ assessment: Severe risk. Exposure enables identity theft, synthetic identity creation, credit fraud, and long-term financial exploitation. The data is highly persistent and difficult for victims to remediate.
Breach Impact
If accurate, the identity and contact attributes support large-scale phishing, profiling, and identity fraud; the inconclusive provenance means attribution to Experian is not established.
About Experian
Experian is a global information services company best known for consumer credit reporting and data analytics. Headquartered in Dublin and listed on the London Stock Exchange, the firm operates as one of the three major credit bureaus serving the United States, alongside Equifax and TransUnion, and runs additional consumer-data, marketing, and identity services in dozens of countries. Its U.S. operations process credit applications, fraud-prevention data, and marketing-segmentation files for thousands of corporate clients in lending, telecommunications, retail, and financial services.
Why They Hold Your Data
Credit reporting and financial analytics firms aggregate highly sensitive identity, contact, credit, financial, employment, and scoring-related data across large populations for lending and risk assessment purposes.
Recent Developments
A multistate settlement announced in November 2022 saw Experian agree to pay roughly $22.5 million and T-Mobile $2.5 million to resolve attorneys-general investigations tied to the 2015 incident. Experian itself remains an active and growing global business, with continued expansion in identity-protection services, fraud analytics, and consumer-direct credit products. The firm has been linked to other breach disclosures in subsequent years, including a separate Experian South Africa incident in 2020. Aggregated datasets attributed to Experian continue to surface periodically on dark-web marketplaces, complicating consumer remediation more than a decade after the original 2015 disclosure.
