Millions of BSNL Subscribers at Risk: Threat Actor Breaches Data Systems, Plans SIM Cloning

New Delhi, India – A recent report reveals a concerning security breach affecting Bharat Sanchar Nigam Limited (BSNL), India’s state-owned telecom giant. A threat actor has reportedly compromised BSNL’s data systems, potentially gaining access to sensitive information of millions of subscribers. This breach raises alarm bells, as the attacker is suspected to be planning to use the stolen data for SIM cloning, a serious security threat that could lead to identity theft and financial fraud.

Data Breach Details

Make fraudulent transactions: Carry out financial transactions using the compromised phone number, leading to financial losses.
