T-Mobile Hacked — 2 Million Customers' Personal Data Stolen

Aug 24, 2018
T-Mobile today confirmed that the telecom giant suffered a security breach on its US servers on August 20 that may have resulted in the leak of "some" personal information of up to 2 million T-Mobile customers.

AI-Powered SaaS Security: Keeping Pace with an Expanding Attack Surface

AI-Powered SaaS Security: Keeping Pace with an Expanding Attack Surface

Organizations now use an average of 112 SaaS applications —a number that keeps growing. In a 2024 study, 49% of 644 respondents who frequently used Microsoft 365 believed that they had less than 10 apps connected to the platform, despite the fact that aggregated data indicated over 1,000+ Microsoft 365 SaaS-to-SaaS connections on average per deployment. And that's just one major SaaS provider. Imagine other unforeseen critical security risks: Each SaaS app has unique security configurations —making misconfigurations a top risk. Business-critical apps (CRM, finance, and collaboration tools) store vast amounts of sensitive data, making them prime targets for attackers. Shadow IT and third-party integrations introduce hidden vulnerabilities that often go unnoticed. Large and small third-party AI service providers (e.g. audio/video transcription service) may not comply with legal and regulatory requirements, or properly test and review code. Major SaaS providers also have thous...

Yes, the customer service staff member tried to sell the T-Mobile customer marketing database, though it is not clear that how much of names, e-mail addresses, account numbers and other personal data of over 1.5 Million customers the database contained. The T-Mobile Czech Republic has also refused to provide any "additional specific information" about what data was leaked, due to an ongoing police investigation. Although the company assured its customers that the stolen database did not contai...
