Abstract
A method for detecting a malicious device in a communication network, corresponding communication device and computer program. The method is implemented in a communication device configured with at least one name resolution server which is referred to as a legitimate name resolution server and associated with at least one network interface through which the communication device is able to communicate using at least one first identifier. The method includes: obtaining at least one second identifier, separate from the first identifier, for the communication device and the at least one network interface; obtaining configuration information from a name resolution service for the communication device using the at least one second identifier; and detecting presence of a malicious device in the event of an anomaly in the processing of a name resolution request sent by the communication device using the at least one second identifier and the obtained configuration information.
