IT Act 2000 · Sections 43 and 66

Entering someone's device without permission is illegal in India

Under Section 43 of the IT Act, accessing a computer, phone, network or data without the owner's permission makes you liable to pay compensation, even with no bad intent: it is a civil wrong. Do the same act dishonestly or fraudulently and it becomes a crime under Section 66, punishable with up to 3 years in jail, a fine of up to ₹5 lakh, or both.
