Summary

A sophisticated UPI scam targets Android users through malicious QR codes that trigger device takeover via Android Intent payloads, allowing fraudsters to bind victims' phone numbers to their own devices and access all linked bank accounts. Users can protect themselves by dialing *99# to block UPI, calling 1930 to report fraud, checking SMS forwarding with *#21#, and only scanning QR codes through official banking apps.

    🚨 NEW UPI SCAM: The "Rogue Auto QR Code" Device Takeover 🚨 A highly sophisticated UPI scam is targeting commuters using Android phones. Within minutes, victims are seeing their bank accounts linked to remote devices without their consent. Here is exactly how this technical exploit works and how to protect yourself: 💻 The Mechanics: How It Happens 1. The Hijacked QR: The fraudster displays a custom QR code. It does not open a secure payment page. Instead, it triggers an Android deep-link "Intent" payload. 2. The Forced Verification SMS: The malicious code forces the victim's phone to draft and send a hidden, encrypted UPI registration token (like the cryptic HDFCUPI... text seen at the bottom of the screenshot). 3. The Remote Device Bind: The scammers enter the victim's phone number into multiple banking apps on *their own burner devices*. When the victim's phone broadcasts that encrypted SMS token, NPCI systems mistakenly validate the *scammer's* phone as the legitimate primary device. 4. The Multi-Bank Explosion: Once the phone number is bound to the scammer's handset, automated scripts fetch every bank account linked to that number (HDFC, Axis, ICICI, etc.) in a matter of minutes. 🛡️ 100% Sure-Fire Kill Switches If you or someone you know receives a sudden flood of UPI activation messages: * Dial *99# Immediately: From the affected SIM, dial this universal USSD code. Select the option to Block UPI or Disable UPI Profile. This works instantly across all banks without needing internet. * Call 1930: Reach out to the National Cyber Crime Helpline immediately to report active device-binding fraud and freeze downstream channels. * Check SMS Forwarding: Dial *#21# to ensure the hacker hasn't secretly set up call or SMS forwarding. If they have, dial ##002# to wipe it out. * De-register Your Apps: If you still have access to your Google Pay, PhonePe, or BHIM apps, go to settings and select De-register UPI Profile. This forces a termination of all external sessions. 💡 Golden Rule of Prevention NEVER scan a street vendor or driver's QR code using your phone's default camera app or generic QR scanners. Always open a trusted, official app like Google Pay, PhonePe, BHIM, or your official banking app to scan. Safe payment interfaces will strictly block malicious device-binding intents. Stay vigilant and share this to protect others! 🧵👇 #CyberSecurity #UPIFraud #TechExplained #SafeBanking #India @Cyberdost @MTPHereToHelp @MumbaiPolice

    My sister booked an Uber auto MH02EF3779. After the ride, the driver showed a fraudulent QR code. My sister suspected this and paid in cash. However, after a few minutes, she started receiving many messages from different banks for UPI registration. Please help. @MTPHereToHelp @MahaCyber1 @Cyberdost @UberIN_Support
