Data Breaches

What a data-breach notification really means (and what to do)

So your inbox says your data was leaked. Here's how to tell whether to shrug or actually panic.

What a data-breach notification really means (and what to do)

Two kinds of leaks

Not every leak is equal. Sort yours into one of these buckets.

Bucket A — Low-stakes: email + hashed password.

Bucket B — High-stakes: government ID (Aadhaar / PAN), address, phone, DOB, or cleartext password.

If you're in Bucket A

  • Check reuse on haveibeenpwned.com.
  • Change the password on the breached site and anywhere you reused it.
  • Turn on MFA on that account.
  • You're done. Move on.

If you're in Bucket B

This is identity-theft territory. Do all of the above, and:

  • Lock your Aadhaar biometric at uidai.gov.in.
  • Get a free credit report from CIBIL / Experian / Equifax; dispute anything you don't recognise.
  • Set a fraud alert on your primary bank — ask them to flag any address / phone-number change requests.
  • Consider a fresh SIM card if your number was in the dump (SIM-swap risk).

A note on "delete my data" requests

Under India's DPDP Act you have a right to request erasure. In practice the response time is measured in months, and data already leaked cannot be un-leaked. Treat it as a cleanup step, not a fix.
