A report by cyber security research firm CyberX9 has said 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.
The report said vulnerabilities exposed the call data records, comprising the time when a call was made, the call’s duration, the call’s location, the customer’s full name and address, and SMS details comprising 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.
Speaking to news agency PTI, CyberX9’s founder and managing director Himanshu Pathak said on Sunday the firm shared its entire findings with Vodafone Idea via email.
Vodafone Idea, meanwhile, had denied the claim of the call data of 20 million postpaid customers being exposed. Vodafone Idea added it regularly carried out checks and audits to further strengthen its security framework.
