Abstract
Embodiments herein relate to a method performed by a detecting node () in a communications network (), for detecting that a wireless device, WD, () associated with a first domain of the communications network () has been communicating with a non-legitimate device (). The non-legitimate device () is a device associated with a second domain of the communications network (). The non-legitimate device () impersonates a network node () of a first domain of the communications network (). The detecting node () obtains information regarding one or more protocol events related to the communication between the WD () and a first network node (). The information comprises a time instance related to the one or more protocol events. The detecting node () determines, based on the time instance and a set of time limits related to the one or more protocol events, that the WD () has been communicating with the non-legitimate device ().
