A viral message falsely claims that State Bank of India (SBI) customers must download an APK file to update Aadhaar details or face their YONO app being blocked. The Press Information Bureau (PIB) has debunked this claim as fake and misleading. SBI also warns that fraudsters use such fake APK links to steal sensitive banking and personal information, leading to financial loss. Both PIB and SBI advise users not to download suspicious APKs or share personal data.
