Texas Drug and Alcohol Testing Service Hack Exposes Nearly 750,000 Records
What happened
The Alcohol & Drug Testing Service (TADTS), a Houston‑based firm that provides workplace drug and alcohol testing for private employers and government agencies, has disclosed a significant data breach affecting approximately 748,763 individuals. The company originally reported the July 2024 incident to Texas regulators as impacting only 250 Texans, but a filing with the Maine Attorney General on July 18 2025 revealed the true scope[1]. The cybercrime group Bian Lian claimed responsibility for the hack and had listed TADTS on its dark web site last July[2].
What information was compromised
In a breach notice posted on its website, TADTS said it became aware of the security issue on July 9 2024[3]. During their investigation, the company learned that an unauthorized actor downloaded sensitive data, although TADTS said there is currently no evidence of identity theft or fraud[4]. The stolen information may include names, dates of birth, Social Security numbers, driver’s license or passport numbers, bank and financial account details, credit/debit card information, usernames, passwords, health‑insurance details, U.S. Citizenship and Immigration Services or alien registration numbers and even biometric data[5]. TADTS has strengthened its IT systems and implemented additional monitoring tools to prevent similar incidents[6][7].
Why it matters
This breach demonstrates how even third‑party service providers can become lucrative targets for ransomware gangs. TADTS handles testing for industries such as transportation, aviation, pipeline and oil and gas, so the stolen data could be used to commit identity theft, tax fraud or impersonation. Nearly three‑quarters of a million people now face long‑term risks due to the exposure of extremely sensitive personal and biometric data. Consumers who received a notice should take advantage of any offered credit monitoring and consider placing fraud alerts or credit freezes on their accounts to mitigate damage.
