An unverified SBI data breach claim alleges that a threat actor named Siriusim posted customer records and banking documents online.
Summary
The claimed dataset contains 375,000 CSV rows and 2,722 PDF files, but those figures do not establish that 3.75 lakh unique customers were affected. CyberPulse reported the allegation on October 16, 2026.
This is a brief wire summary, the full story (linked below) has the complete details.
KazaSec's take
Incidents like this rarely start with the headline event itself, they usually trace back to an exposed remote-access endpoint, an unpatched perimeter system, or a credential phished weeks earlier. The organizations that recover fastest are the ones that tested their defenses and their incident response plan before they needed them.
