Credit bureau TransUnion suffered a major data breach on July 28 that exposed sensitive information of 4.4 million customers. The breach compromised names, Social Security numbers, and birthdates through unauthorized access to a third-party application storing customer data. State filings reveal conflicting details about what information was accessed, but the most serious filing from Texas confirms Social Security numbers were exposed. Since the breach occurred months ago, experts warn the stolen data may already be circulating on the dark web. TransUnion is offering affected customers 24 months of free credit monitoring and notifying those impacted. Consumer rights firm Wolf Haldenstein advises people to watch for unusual credit report activity and consider freezing their credit. **Source:** [CNET](https://www.cnet.com/tech/services-and-software/credit-bureau-transunion-hit-with-data-breach-affecting-4-4-million-people/)
