SBI YONO APP DATABASE Listed by darkleakmarket Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
The SBI YONO APP DATABASE Listed by darkleakmarket Ransomware Group (reported September 9, 2021) is an unverified claim; the data involved is undisclosed belonging to roughly unknown people. If you have an account with them, your information may now be circulating on the open web and with data brokers. Here’s exactly what happened, how to check if you were affected, and what to do next.
What happened
The SBI YONO APP DATABASE was listed on the darkleakmarket ransomware leak site on September 9, 2021. The group claims to have stolen internal data. No further details on the date or method of intrusion, the volume of material taken, or any subsequent verification have been made public.
The group behind it: darkleakmarket
Darkleakmarket is a ransomware operator that maintains a public leak site to publish data it says was taken from victims who declined ransom demands. The group follows the common double-extortion model: encryption of systems combined with the threat of data release. Its listings have included entities across multiple sectors in prior incidents documented by security researchers.
About SBI YONO APP DATABASE
SBI YONO is the mobile banking platform operated by the State Bank of India, one of the country's largest public-sector banks. Applications of this type routinely process account access, transaction records, and customer identifiers. A breach affecting such a system therefore touches data categories that financial institutions are legally obligated to safeguard.
What data was at risk
The only description provided is that internal files were allegedly exfiltrated. The precise categories of information contained in those files remain undisclosed. Organisations operating banking applications typically hold customer identifiers, account numbers, transaction histories, and authentication details, yet it is not confirmed whether any of these were among the claimed material.
What's at stake
Individuals whose information appears in banking databases face the possibility of account takeover, identity misuse, or targeted fraud if the files are later distributed. The organisation may encounter regulatory scrutiny and remediation costs. No confirmed instances of downstream harm tied to this listing have been reported.
Were you affected?
Because the number of individuals involved and the exact data types remain unknown, anyone who uses SBI YONO should treat the situation as unconfirmed exposure. Practical steps include:
- Review recent account statements for unauthorised transactions.
- Enable or strengthen multi-factor authentication on the app and linked services.
- Monitor credit reports and bank alerts for unusual activity.
- Run a free exposure scan of your email address against known breach repositories to check for prior appearances of your information.

Breach listings — particularly those originating from ransomware or leak sites — are third-party claims that may be unverified, incomplete, or inaccurate. A listing does not by itself confirm that a breach occurred or that any specific data was exposed. Severity is an automated assessment, not a definitive rating. Verification status is shown where available.
Attributions to threat groups and methods reflect public reporting and, in some cases, unverified claims made by the groups themselves; they may be incomplete or later revised.
