An unprotected server storing millions of call logs and text messages was left open for months before they were found by a security researcher.

If you thought you’d heard this story before, you’re not wrong. Back in November, another telecoms company Voxox exposed a database containing millions of text messages — including password resets and two-factor codes.

He told TechCrunch that the logs were updated daily and went up to January 8 — the day the database was pulled offline. Many of the files contained highly detailed call records of who called whom, the time and date, and more.

Some of the numbers in the call logs were scrubbed, Paine said, but text message logs...
