A hacker group calling itself Siriusim has claimed to possess confidential customer information allegedly linked to the State Bank of India (SBI), raising fresh concerns about data security in India’s banking sector.

According to a cybersecurity monitoring account, the group claims to hold approximately 3.8 lakh data entries in CSV format, along with 2,722 PDF documents. The reported material may include personal information, residential addresses, loan applications, supporting documents and account-opening records.

The claim was highlighted by CyberPulse56, which reportedly first shared information about the alleged dataset on October 16. However, the authenticity and origin of the data have not been independently confirmed.

The reported number of entries also does not necessarily represent the number of affected customers, as multiple records could belong to the same individual. There is currently no independent confirmation that SBI’s systems were compromised or that the documents originated directly from the bank.

If the information is genuine, exposed personal and financial records could potentially be misused for identity theft, financial fraud, targeted phishing attempts or fraudulent loan applications.

The allegation highlights the importance of strong cybersecurity measures for financial institutions that handle large volumes of sensitive customer information. Until the claim is verified, it should be treated as an allegation rather than a confirmed data breach.
