  • Patent number: 10862675
    Abstract: A method exchanges messages with different security classes between security-relevant devices. Key pairs containing a private key and a public key corresponding to the private key are assigned to each security class, wherein the keys and key pairs of each security class differ from each other. Each security-relevant device has all the public keys for decrypting messages for each security class and the relevant private keys for encrypting messages corresponding to a security class that is lower than or equal to the security class of the security-relevant device. Upon receipt, the security class for the message is identified by decryption by use of the public key.

  • Patent number: 10762200
    Abstract: Disclosed herein are systems and methods for enabling the automatic detection of executable code from a stream of bytes. In some embodiments, the stream of bytes can be sourced from the hidden areas of files that traditional malware detection solutions ignore. In some embodiments, a machine learning model is trained to detect whether a particular stream of bytes is executable code. Other embodiments described herein disclose systems and methods for automatic feature extraction using a neural network. Given a new file, the systems and methods may preprocess the code to be inputted into a trained neural network. The neural network may be used as a “feature generator” for a malware detection model. Other embodiments herein are directed to systems and methods for identifying, flagging, and/or detecting threat actors which attempt to obtain access to library functions independently.

  • Patent number: 10749883
    Abstract: Described is an automatic anomaly detector that receives a time-series of normal and abnormal activities that include features related to entities within a computing system. A feature coherence graph for the features is constructed, with the graph then clustered such that feature spaces of entities are expanded to include features that live within a same cluster but belong to separate entities. The feature spaces are unified by mapping representations of the features spaces into a Euclidean space of feature vectors. The feature vectors related to each feature are then aligned. Sets of clusters of related abnormal activities are then generated by regressing each feature vector over only those features that it possesses. The sets of clusters are used to detect anomalous behavior. The system then identifies a node within the computer system generating the anomalous behavior and initiates an action to minimize a threat posed by the node.
