Abstract
In some aspects, the techniques described herein relate to a method including: receiving an identity of fraudulent user equipment (UE); identifying a plurality of candidate UEs based on locations associated with the fraudulent UE and a duration of a session of the fraudulent UE; computing vectors representing the plurality of candidate UEs based on activity data associated with the plurality of candidate UEs recorded during the duration; comparing the plurality of vectors to a vector associated with activity data associated with the fraudulent UE to compute distances between the plurality of candidate UEs and the fraudulent UE; sorting the plurality of candidate UEs based on the distances; storing a top subset of the plurality of candidate UEs as co-located UEs; and performing an action using the top subset of the plurality of candidate UEs.
