Abstract
The solution introduces a method and system in a network node of a telecommunication network such as the MME. The method includes receiving, from an eNodeB, an attach request that originated from a UE, the attach request including an identifier associated with a subscriber of the UE; checking a UE blacklist to determine whether the identifier in the attach request is on the UE blacklist; in response to the UE identifier being on the UE blacklist: rejecting the attach request; updating a success rate metric to reflect the failed attach request; comparing the success rate metric to a threshold; and in response to a decrease in the success rate metric below the threshold, recognizing a malicious attack and taking mitigating steps.
