Piracy on the internet was an act of violating intellectual property rights and was illegal. According to the provisions of China's " copyright law," without the permission of the copyright owner, no individual or organization may copy, distribute, perform, show, broadcast, or spread information through the Internet to exploit the works of others. If the act of online plagiarism violates the rights of the copyright owner, the copyright owner has the right to ask the offender to stop the violation, compensate for the losses, and file a lawsuit for further economic disputes. At the same time, according to the provisions of the "Internet Security Law", no individual or organization may illegally obtain, use, share, or spread the works of others. They may not engage in Internet copyright activities through illegal means. If the act of internet theft violates the provisions of the law, the network security manager has the right to take measures to stop it and investigate and deal with the offender. Therefore, the act of internet theft not only violates the rights of copyright owners, but also violates the provisions of the Internet Security Law. It is an illegal act and should be punished by law.
