Tange, Mann & Garza, P.C.’s Data Breach Investigation

According to the notice filed with the Texas Attorney General, the security incident affecting Tange, Mann & Garza, P.C. occurred on or around May 20, 2026, and was reported to Texas regulators on July 21, 2026.

Accounting and financial services firms are common targets for cybercriminals because they routinely handle Social Security numbers, tax records, bank account information, and other data that can be directly monetized through identity theft or financial fraud. A breach at a firm of this kind can expose not just current clients but also historical records tied to tax filings and financial planning services going back years.

When a company does not publicly specify which categories of information were exposed, affected individuals are often left uncertain about their actual level of risk. In these situations, it is prudent to assume that any personal or financial information on file with the firm, including names, Social Security numbers, and financial account details, could potentially have been accessed, and to take precautionary steps accordingly.

The roughly two-month window between the reported incident date and the notification filed with the Texas Attorney General is consistent with the investigation and notification timelines many businesses follow after discovering a security incident, as they work to determine scope and prepare required disclosures.
