An event can be analyzed for association with a security violation. Characters or other values of event data (e.g., command-line text) associated with the event can be provided sequentially to a trained representation mapping to determine respective representation vectors. Respective indicators can be determined by applying the vectors to a trained classifer. A token in the event data can be located based on the indicators. The event's can be determined to be associated with a security violation based on the token satisfying a token-security criterion. The representation mapping can be trained by adjusting model parameters so the trained representation predicts, based on a character of training command-line text, an immediately following character in the training command-line text. The classifier can be determined based on the trained representation mapping and classification training data indicating whether respective portions of training event data are associated with security violations.
