Section 65 of the Information Technology Act, 2000, specifically addresses the offence of "Tampering with computer source documents." It criminalizes the act of knowingly or intentionally concealing, destroying, or altering any computer source code used for a computer or computer network, when that source code is required to be kept or maintained by law. This provision is crucial for protecting the intellectual property and integrity of software. It is distinct from Section 66 (Hacking with computer systems) and Section 67 (Publishing obscene information in electronic form).
