Abstract
Methods, systems, and apparatus, including computer programs encoded on computer storage media, for detecting fraudulent accounts. One of the methods includes obtaining raw data from network events associated with a collection of user accounts of an online service; processing the raw data including determining a feature set and applying the feature set to generate user groups each comprising one or more user account; evaluating each user group based on feature distributions including performing one or more Major-Key-Shared (MKS) correlation calculations on pairs of features from the feature set for the group; scoring each group based on the evaluation; and identifying groups having a score that exceeds a specified threshold as fraudulent.
