There is provided a system and a computerized method of remediating one or more operations linked to a given program running in an operating system, the method comprising: querying a stateful model to retrieve a group of entities related to the given program; terminating at least a sub set of the group of entities related to the given program; generating a remediation plan including one or more operations linked to the given program, the one or more operations being retrieved based on the group in the stateful model; and executing the remediation plan by undoing at least part of the one or more operations linked to the given program thereby restoring state of the operating system to a state prior to the given program being executed. There is further provided a computerized method of detecting malicious code related to a program in an operating system in a live environment.

Method of remediating operations performed by a program and system thereof

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.

Systems and methods for executable code detection, automatic feature extraction and position independent code detection

There is provided a method for generating a representation for behavior similarity comparison by generating a program-level stateful model of one or more entities in a computer operating system operating on a computer system, the program-level stateful model having a data structure representing a state of a program; generating an updated representation of the program based on the program-level stateful model; searching for at least one other representation of another program-level stateful model similar to the updated representation of the program; and comparing the updated representation of the program to the at least one other representation of another program-level stateful model.

There is provided a system comprising a processor operatively connected to a memory, the memory comprising: a program-level stateful model configured to model one or more entities in a computer operating system operating on the computer system, the program-level stateful model comprising: a data structure representing a state of a program, wherein the data structure comprises: a network of one or more interconnected objects representing the one or more entities constituting the program, wherein the one or more interconnected objects are derived from a sequence of operations performed in a live environment; one or more relationships among the one or more interconnected objects and the sequences of operations; and one or more object groups, wherein the one or more object groups are formed by dividing the one or more interconnected objects according to a predefined grouping rule set, and wherein each group of the one or more object groups comprises objects representing a corresponding group of entities related to the program running in the live environment.

There is provided a system and a computerized method of remediating a given program running in an operating system, the method comprising: querying a stateful model to retrieve a group of entities related to the given program; terminating at least a sub set of the group of entities related to the given program; generating a remediation plan including one or more operations linked to the given program, the one or mare operations being retrieved based on the group in the stateful model; and executing the remediation plan by undoing at least part of the one or more operations linked to the given program thereby restoring state of the operating system to a state prior to the given program being executed. There is further provided a computerized method of detecting malicious code related to a program in an operating system in a live environment.
