After a scam, the hard part is knowing what to fix first. Start with your primary email, then banking and payment apps, WhatsApp, cloud backups, social accounts, and work accounts. Change passwords from a trusted device, revoke active sessions, enable two-factor authentication, and contact your bank if money or payment details were exposed.

The exact cleanup depends on what happened, so first write down what the scammer actually got.

Step 1: Write down what was shared

Make a quick list. It does not need to be neat:

  • OTP
  • Password
  • UPI PIN
  • Card number, CVV, or PIN
  • Net banking details
  • Aadhaar, PAN, passport, or other ID
  • Email access
  • WhatsApp access
  • Remote access to phone or computer
  • APK or unknown app installed
  • Payment sent
  • Photos, documents, or contact list exposed

That list decides the order of cleanup.

Step 2: Secure your main email first

Your email account is the recovery key for many other accounts.

From a trusted device:

  1. Change the email password.
  2. Sign out of all other sessions.
  3. Review recovery phone and recovery email.
  4. Turn on two-factor authentication.
  5. Check forwarding rules and filters.
  6. Review recent security activity.
  7. Remove unknown connected apps.

If the scammer controls your email, they can reset many other accounts.

Step 3: Secure banking, wallets, and UPI

Contact your bank or payment app immediately if:

  • You shared OTP, UPI PIN, card details, or net banking details
  • You installed a remote access app
  • Money moved
  • You see unknown beneficiaries or transactions
  • The scammer saw your screen while a banking app was open

Ask the provider to block risky access, review transactions, and guide the next steps.

Step 4: Secure WhatsApp

If the scam involved WhatsApp:

  • Check linked devices
  • Remove unknown linked devices
  • Enable two-step verification
  • Warn close contacts if impersonation is possible
  • Do not share the 6-digit registration code
  • Watch for messages asking contacts for money

WhatsApp takeover scams often target your contacts next.

Step 5: Remove risky apps and permissions

If you installed an APK, remote access app, screen sharing app, or loan app:

  1. Disconnect any active session.
  2. Uninstall the app.
  3. Review accessibility permissions.
  4. Review notification access.
  5. Review SMS, contacts, files, and screen recording permissions.
  6. Run a security scan if available.
  7. Change important passwords from another trusted device.

If the device still behaves strangely, get professional help or consider a full reset after backing up important data.

Step 6: Change reused passwords

If you typed a password into a suspicious page, change it everywhere it was reused.

Prioritize:

  • Email
  • Banking and wallets
  • Social media
  • Cloud storage
  • Work accounts
  • Shopping accounts with saved cards
  • Telecom and SIM-related accounts

Use unique passwords for each account.

Step 7: Preserve evidence

Save:

  • Phone numbers
  • URLs
  • Screenshots
  • App names
  • UPI IDs
  • Bank account details
  • Transaction IDs
  • Chat logs
  • Emails
  • APK file names
  • Remote access codes if visible

Evidence helps banks, platforms, and cybercrime reporting teams understand what happened.

Step 8: Expect follow-up scams

After a scam, victims are often targeted again. The next message may pretend to be a refund, recovery agent, police officer, lawyer, or platform support team.

Watch for:

  • Recovery agents asking for fees
  • Fake police or lawyer threats
  • Refund messages
  • More OTP requests
  • Calls claiming your complaint can be fast-tracked
  • People asking you to move money to a safe account

Do not pay anyone who promises to recover money through a private channel.

What to send to Kaval

Send the message, link, payment screenshot, app name, or situation summary to Kaval.

The cleanup plan should depend on what was exposed:

  • OTP shared
  • Link clicked
  • Password entered
  • Remote access installed
  • Payment made
  • WhatsApp compromised
  • Data leaked

For a specific link-click incident, read I clicked a phishing link. What should I do now?.

The short version

Secure email first, then money accounts, WhatsApp, cloud, social, and work accounts. Change passwords from a trusted device, revoke sessions, enable two-factor authentication, remove suspicious apps, preserve evidence, and contact your bank immediately if payment details or money were involved.
