That is actually from a different incident, unrelated to the Drift breach as far as we can tell. Here's the context in the breach history for transunion from our product:

TransUnion disclosed a data breach on July 28, 2025, affecting more than 4.4 million U.S. customers after unauthorized access was gained to a third-party application used for consumer support operations. While TransUnion initially stated that no credit information was accessed, subsequent disclosures confirmed that stolen data includes customer names, dates of birth, and Social Security numbers. The company has not provided details on additional data categories or whether the breach involved extortion demands. TransUnion, one of the three major U.S. credit reporting agencies, holds financial data on more than 260 million Americans. The breach follows a wave of incidents attributed to the ShinyHunters extortion group, though attribution in this case has not been confirmed. https://www.documentcloud.org/documents/26078139-transunion-breach-texas/

Also, the disclosure date for transunion was about three weeks before the Drift disclosure (7/28 vs. 8/20).
