Abstract: A computing device for informing about malicious web resources and a method for informing about malicious web resources performed on this computing device are claimed. The claimed method includes performing operations wherein: obtaining references to a plurality of web resources; identifying malicious web resources in a specified set of web resources; establishing web resources associated with each of the identified malicious web resources; detecting malicious web resources in the identified related web resources; identifying at least one authorized entity associated with each of the identified malicious web resources; generating at least one report for at least one of the established authorized entities based on information about the detected malicious web resources associated with this authorized entity; sending each generated report to the appropriate authorized entity on the basis of the contact details of the authorized entity.

Abstract: A computing device for detecting suspicious users in a plurality of messaging systems and a method for detecting suspicious users therein executable the computing device are proposed. The claimed method includes: receiving a plurality of user messages from a plurality of messaging systems; analyzing each of the received user messages to identify at least one message suspiciousness indicator from a predetermined set of message suspiciousness indicators; if at least one message suspiciousness indicator is detected in the analyzed user message, identifying at least one user associated with the analyzed user message in one of the plurality of messaging systems; assigning each of the identified users a user suspiciousness indicator depending on the identified message suspiciousness indicators; classifying users in the one of the plurality of messaging systems as suspicious their reputation score exceeds a predetermined reputation threshold limit.
