Abstract
An information leakage detection method and a device using the same are disclosed. The method includes the following steps. Network connection data of an electronic device is obtained. Log data related to a (domain name system) DNS is extracted from the network connection data. A DNS request in the log data is analyzed to obtain multiple character distribution feature values according to an analysis result. The character distribution feature values reflect a character distribution status of a domain name in the DNS request under different classification rules. A machine learning model determines whether the DNS request is a malicious DNS request according to the character distribution feature values, and the malicious DNS request is used to carry leaked data to a remote host.
