Latest Patents

One of Dagmawi's latest patents is titled "Security systems and methods for detecting malleable command and control." This patent presents a network security system (NSS) that reliably detects malleable command and control (C2) traffic. The NSS intercepts outgoing transactions from user devices associated with user accounts. It filters out transactions to known benign servers and analyzes the remaining transactions for indicators of malleable C2, including heuristic, anomalous, and pattern-based detections. The NSS lowers the user confidence score associated with the user account or device based on the severity and number of detected indicators for each impacted outgoing transaction. When the user confidence score decreases below a threshold, the NSS implements a restricted security protocol for future outgoing transactions. Based on the detected indications, the NSS can identify malleable C2 attacker servers and add them to a blacklist of destination servers to further identify infected user accounts and devices.

Another notable patent is "ML-based encrypted file classification for identifying encrypted data movement." This technology facilitates User and Entity Behavior Analytics (UEBA) by classifying a file being transferred as encrypted or not. It involves monitoring the movement of files by a user over a wide area network and detecting file encryption using a trained classifier. The detection process includes various tests, such as a chi-square randomness test and a Shannon entropy test. The system counts the number of encrypted files moved by the user in a predetermined period and generates an alert if the user exceeds the maximum allowed number of encrypted files.
