What happened in the Baker Tilly data breach
According to its notice letter, on September 6, 2026, Baker Tilly became aware of a potential cybersecurity incident involving certain information stored on a platform operated by a third-party service provider that Baker Tilly used in connection with services it provides to clients. The letter states that the unauthorized actor was able to obtain data relating to certain Baker Tilly clients. Baker Tilly's report to the Texas Attorney General gives a breach window of September 2 to September 8, 2026.
Baker Tilly says it completed its review of the affected data on October 28, 2026. The sample letters filed in California, Massachusetts and South Carolina are dated November 9, 2026, and the Texas filing says consumers were notified by U.S. Mail. The posted letters show a placeholder where the types of affected information would appear, so they do not show the categories. The Texas filing lists name of individual, address, Social Security Number Information and "Other", and the Massachusetts filing lists Social Security numbers. The letters offer two years of credit and identity monitoring through Experian IdentityWorks.
Baker Tilly reported 195,512 affected individuals to the Texas Attorney General, including 10,456 Texans. The Massachusetts filing lists 2,689 Massachusetts residents, the South Carolina filing lists 1,359 South Carolina residents, and the letter states that 111 Rhode Island residents were notified. A separate version of the letter was addressed to parents or guardians of minors whose information was affected.
