How RISX works

We index publicly reported online financial fraud from Indian national media, regulator advisories, and official channels.
Each alert is structured into plain-language intelligence — what happened, who was affected, risk indicators, and source links when available.
Check clues, explore patterns and geography, and review trends — research, analytics, and education in one public platform.

Our methodology & sources · Public risk intelligence from open reporting — not a bank helpline or real-time blocklist.

Already lost money or shared OTP? Call within 24 hours so the bank can try to freeze the money.

What to do for this type of scam

Use this if you got similar messages or may have already lost money. Check red flags first, then first-hour steps.

Red flags for this scam type
If affected — first steps
Official reporting channels & helplines

Red flags this scam usually shows

If a message, call, or page involves any of these, treat it as suspicious — even if it looks like the alert above.

Pushes you to act in a hurry
Real organizations give you time. Threats like 'your account will be closed in 30 minutes' are designed to panic you into mistakes.
Asks for OTP, PIN, CVV, or password
Banks, UPI apps, government offices, and police never ask for these. Anyone asking is trying to steal your money.
Sends you a link or APK to install
Tapping unknown links or installing unverified apps can give scammers full access to your phone and bank accounts.
Asks for an advance, processing fee, or 'refund tax'
Real refunds, prizes, jobs, or loans never require you to pay first. If you must pay to receive something, it is a scam.
Offer sounds too good to be true
Huge cashback, guaranteed jobs, lottery wins, or sky-high returns are classic bait. If it feels unreal, it is.

Time-sensitive

If you were affected by this scam

First-hour steps — the crisis box above covers the emergency call to 1930.

Stop the call or chat right now
Hang up, leave the chat, and do not click any more links. Every extra minute is more risk. Take a breath; you are not alone in this.
Block your card and freeze the account
Call your bank's official helpline (printed on the back of your card or on the bank's website) and ask them to block the card and temporarily freeze online transactions. Do not call numbers a stranger gave you.
Change passwords and revoke device access
Change passwords for net banking, UPI apps, and email. In your UPI app, remove any 'linked devices' you do not recognize. Turn on two-factor authentication where possible.
Report to the National Cyber Crime Helpline within 24 hours
Call 1930 or file a complaint at cybercrime.gov.in. Reporting within the first 24 hours gives the best chance of freezing the money before it moves.
