Arnold Oil Company of Austin, L.P. Data Breach

Arnold Oil Company of Austin, L.P.’s Data Breach Investigation

Arnold Oil Company of Austin, L.P., headquartered in Austin, Texas, reported a data security incident to the Texas Attorney General’s Office affecting approximately 865 individuals. According to the filing, affected individuals were notified by U.S. Mail. The Texas AG filing lists the exposed information as including names, Social Security numbers, driver’s license numbers, medical information, health insurance information, and an additional unspecified data category listed only as “Other.”

This combination of Social Security numbers, government-issued identification, and health-related information is particularly sensitive, since it can potentially be used together to commit identity theft, file fraudulent insurance claims, or open new lines of credit in a victim’s name. Companies that maintain employee health and benefits records, such as fuel and lubricant distributors that also manage workforce HR data, are common targets for this type of combined-data breach because the records are valuable on secondary markets.

The public Texas AG filing does not disclose the specific cause of the incident (for example, whether it resulted from a ransomware attack, phishing scheme, or unauthorized access to an internal system), nor does it list exact breach detection or discovery dates. Individuals with questions about the specific circumstances of the incident are encouraged to review any direct notice letter received from Arnold Oil Company.

What Information Was Breached?
