My WhatsApp was hacked from a Noida device and the hacker messaged my contacts asking for money. What do I do?

Detailed Legal Analysis

Immediately log out of all devices via WhatsApp Web settings and enable two-step verification with a new PIN. File an FIR at the cyber crime police station in Noida under Section 66C IT Act, 2000 (identity theft) and Section 318(4) BNS, 2023 for cheating.

Inform your contacts about the compromise through another channel to prevent further fraud. Report the incident on the National Cyber Crime Reporting Portal and to WhatsApp support.

Preserve the device logs and suspicious login alerts as electronic evidence under Section 63B BSA, 2023. If funds were transferred, request the bank to freeze the beneficiary account.

If police do not act, approach Allahabad High Court under Article 226. Check Uttar Pradesh Rent Control Act 1972 for state-level cyber fraud response protocols.
