Data of 20 million Vodafone Idea customers exposed

Cybersecurity researchers reported that multiple vulnerabilities in the system of Vodafone Idea (Vi) exposed the call data records of 20.6 million customers subscribed to the telecom giant's postpaid services.

Exposed data includes:

The time when a call was made,
The call's duration,
The call's location,
The customer's full name and address,
SMS details including the contact number to which it was sent.

The call data records exposed also compromised the personal data of such postpaid customers, their internet usage and roaming details, the report added.

"Vodafone Idea acknowledged the vulnerabilities discovered and reported by us on August 24," researchers said.

Vodafone Idea, however, had denied the claim of the call data of 20 million postpaid customers being exposed:

There is no data breach as alleged in the report. The report is false and malicious. Vi has a robust IT security framework to keep our customer data safe.

The other day, a technology provider for the world’s largest airlines Accelya reported it became a victim of a ransomware attack impacting some of its networks.
