"T-Mobile Reveals Second Breach of the Year"

T-Mobile USA has recently begun notifying customers impacted by another breach at the firm, which may have resulted in a significant volume of compromised personal and account data.  The company said in a breach notification letter that its own systems flagged the unauthorized intrusion in March.  A malicious actor had access to hundreds of customer accounts between late February and March 2023.  Although no financial information or call record data was taken, those affected will need to pay careful attention to follow-on fraud attempts.  The company noted that the information obtained for each customer varied but may have included full name, contact information, account number and associated phone numbers, T-Mobile account PIN, social security number, government ID, date of birth, balance due, internal codes that T-Mobile uses to service customer accounts (for example, rate plan and feature codes), and the number of lines.  T-Mobile said it has already reset impacted customers’ T-Mobile account PIN and is offering two years of free credit monitoring and identity theft detection services.
