Abstract: Disclosed herein are systems and methods for detecting harmful scripts. In one aspect, an exemplary method comprises, identifying a file containing a script, wherein the identification of the file is performed by analyzing each file of a plurality of files for a presence of a harmful script, generating a summary of the script based on the identified file, calculating static and dynamic parameters of the generated summary of the script, recognizing a script programming language based on the calculated static parameters and dynamic parameters of the generated summary of the script using at least one language recognition rule, processing the identified file based on the data about the recognized script programming language, generating a set of hash codes based on a processed file using rules for generating hash codes, and detecting the harmful script when the generated set of hash codes is similar to known harmful sets of hash codes.

Abstract: Disclosed herein are systems and methods for detecting an unapproved use of a computing device of a user. In one aspect, an exemplary method comprises, by a security application: detecting a script executing in a browser on the computing device of the user, intercepting messages being exchanged during an interaction of the script with a server, wherein the intercepted messages comprise at least one of messages sent from the script to the server and from the server to the script, analyzing the intercepted messages to determine whether or not attributes of an unapproved use of resources of the computing device of the user are present, detecting the unapproved use of the resources of the computing device of the user when at least one of said attributes is detected.

Abstract: The present disclosure is directed towards systems and methods for detecting hidden behavior in browser extensions. In one aspect, a method is provided including launching a browser in a protected environment, performing one or more actions in the browser, tracking events occurring during the performing of the one or more actions, identifying extension events from the events that are initiated by a browser extension, analyzing the extension events for indications of change that correspond to behavior not previously declared by the browser extension, and determining that the browser extension is performing hidden behavior when indications of change are found.

Abstract: Systems and methods for managing antivirus records. A method can include providing a data store of antivirus records, providing an antivirus application to be executed on each of a plurality of user computers, and executing instructions by a remote server to implement a processing tool configured to collect an antivirus record parameter for a particular antivirus record and collect statistical data of a detection events associated with the antivirus record, and a processing tool to configured to determine a false activation using the antivirus record parameter and the statistical data.
