🧠 Key Legal Takeaways
1. Unauthorized access = Offense under IT Act §§43 & 66
Even if no money is stolen, accessing a banking app illegally is punishable.

Mimicking bank apps is considered digital forgery.
3. SIM swap = Identity theft under §66C
Courts treat SIM swaps as a direct method of identity misuse.
4. Banks can be liable for weak security under §43A
If a service provider neglects security, they may face penalties.
5. Money laundering applies if the hacker layers or transfers stolen funds
Under PMLA, dealing with stolen digital money is a separate offense.
6. Malware, remote access apps, and phishing all qualify as “hacking” legally
