Ransomware Attack at Texas Alcohol & Drug Testing Service Jeopardizes Identities of Texans Featured
Nearly 750,000 individuals exposed in Texas Alcohol & Drug Testing Service ransomware attack
In July 2025, it was revealed that the Texas Alcohol & Drug Testing Service (TADTS) suffered a massive data breach that compromised the sensitive information of nearly 750,000 individuals. If you were ever tested by TADTS for employment, compliance, or government programs, your personal information may now be at risk. Victims of this breach should understand what happened, what information was stolen, and what legal options—including participation in a class action lawsuit—may be available.
What Happened?
The cyberattack took place in July 2024, when the ransomware group BianLian infiltrated TADTS’s systems. Hackers were able to remain inside the company’s network for five days, stealing large amounts of personal and financial data before being detected.
Despite discovering the breach in 2024, TADTS did not notify affected individuals until a year later, in July 2025. Security experts warn that this long delay increased the risk for victims, as stolen data may have been misused during that time without their knowledge.
What Information Was Stolen?
The exposed information is highly sensitive and includes:
- Names and dates of birth
- Social Security and driver’s license numbers
- Passport and other government-issued identification
- Bank account and credit/debit card details
- Usernames, email addresses, and passwords
- Health insurance and biometric data
- Immigration or alien registration numbers
The broad scope of this data creates serious risks of identity theft, financial fraud, and long-term privacy violations.
Who Is Affected?
TADTS has been in business since 1994 and conducts alcohol and drug testing for a wide range of clients, including:
- Federal and state agencies such as the Department of Transportation
- Private employers across multiple industries
- High-risk sectors like aviation, marine, oil and gas, and transportation
Initial reports suggested only a few hundred Texans were affected, but filings with state regulators now confirm that nearly 748,763 individuals nationwide had their information compromised. If you received a breach notification from TADTS, it is a strong indication that your data was part of this breach.
What Should You Do Now?
Even if you have not noticed suspicious activity, experts recommend taking the following steps:
- Review your credit reports and financial statements regularly.
- Change passwords for accounts that may overlap with stolen login details.
- Be alert for phishing attempts, scam calls, or fraudulent applications.
- Consider placing fraud alerts or credit freezes with major credit bureaus.
Because TADTS has not offered identity theft protection or credit monitoring, individuals are left to take these protective steps on their own.
Know Your Legal Rights – Join the Class Action
Victims of this breach may be entitled to seek compensation for:
- Loss of privacy
- Out-of-pocket expenses and time spent on security measures
- Emotional distress and disruption caused by the breach
A class action lawsuit also has the potential to hold TADTS accountable and push the company to adopt stronger security protections.
