On August 20th, telecom giant T-Mobile suffered a cyber attack. The breach resulted in the leak of personal information of about 2 million T-Mobile customers including customers' name, billing zip code, phone number, email address, account number, account type, and encrypted password.

According to T-Mobile, its cybersecurity team detected and shut down an “unauthorized capture of some information.” A spokesperson said, “we found it quickly and shut it down very fast.” As a result, no financial information such as credit card information or social security numbers was compromised.

“we found it quickly and shut it down very fast.”

A T-Mobile spokesperson told Motherboard, a multiplatform multimedia publication, that the breach affected “about” or “slightly less than” 3% of its 77 million customers. The spokesperson also shared  that the hackers were an international group but didn’t give any specifics on whether the hackers were independent criminals or backed by a nation state.

T-Mobile has reached out to victims directly via text message and letters to notify them of the breach. The company also said it has informed law enforcement about the security breach.

This T-Mobile incident is the latest high-profile data breach and furthermore proves that although companies are getting better at detecting breaches, they still haven’t figured out how to prevent them from occurring all together. However, as a consumer, be sure to do your part and practice proper cyber hygiene by doing things like changing your passwords periodically, using passphrases instead of “passwords, and keeping your mobile device software up to date.”
