Abstract
The disclosure provides a backdoor attack method and apparatus for a malicious URL detection system. The backdoor attack method includes: obtaining original URL samples of backdoor URL samples to be generated; determining position information of separator slashes in each URL of the original URL samples, and obtaining a position number result by numbering the position information; determining a backdoor attack mode of the malicious URL detection system based on the position number result, and generating the backdoor URL samples corresponding to the original URL samples by using the backdoor attack mode; and constructing a training set based on a preset ratio of the backdoor URL samples, training a neural network model by using the training set, and testing an attack strength of the malicious URL detection system in the backdoor attack mode by using the trained neural network model to obtain a real-time attack success rate.
