Abstract: Disclosed herein are systems and methods for blocking network connections to network resources of forbidden categories.

Abstract: Disclosed herein are systems and methods for detecting unauthorized alteration with regard to a certificate store. In one aspect, an exemplary method comprises, tracking changes in a file system or a system registry of an operating system of a device with regard to the certificate store, detecting an alteration or an attempted alteration with regard to the certificate and sending information about the alternation or the attempted alteration to an analysis module, obtaining information about at least one certificate with which a change in the file system or the system registry with regard to the certificate store is connected, and determining a class of the change, where the class of the change is determined from a portion of the respective system registry or the file system in which the change occurred and from an action associated with the change, and comparing the obtained information to similar information on known certificates.

Abstract: Disclosed herein are systems and methods for blocking network connections. In one aspect, an exemplary method comprises, intercepting a certificate from the server when establishing a protected connection between a server and a client, determining whether the intercepted certificate is similar to one or more forbidden certificates, the determination of whether the intercepted certificate is similar to one or more forbidden certificates comprising transforming the intercepted certificate in accordance with a method of determining similarities between certificates and a method of saving forbidden certificates in a database of forbidden certificates, and blocking the connection when the intercepted certificate is similar to the one or more forbidden certificates.
