Search — “Siriusim”

SBI told the stock exchange it identified 3,897 customer records containing personal data within a roughly 375,000-record set offered on the dark web, and that the source of the data is unknown. The listed categories (mobile numbers, dates of birth, names, addresses, branch and CIF identifiers, loan lead metadata) carry impersonation and phishing risk rather than direct account access. The filing names no attacker or breach vector and does not confirm whether SBI systems were breached; a BreachForums listing by an actor named Siriusim was reported but not tied to the bank by the filing. No technical behaviors or detection content are published.
