Latest Patents

Chao Lei holds a patent titled "Benign network entities based malicious campaign signature generation." This patent describes a signature generator designed to create a malicious campaign signature that provides substantial coverage of malicious campaign behavior without impeding benign traffic. The generator utilizes data from multiple known malicious campaigns to identify abused, benign network entities. It constructs a graph data structure for each campaign, representing the abused network entities and their relationships. By aggregating these graph structures, the generator identifies combinations of benign network entities that have been highly abused across various campaigns. Ultimately, a signature is created from the identifiers of these highly abused entities.
