Nowadays, users of social networks (Social Network) are increasingly using them to promote businesses,
distribute advertisements for goods and services, leisure, hobbies, personal communication
and information exchange, thus being an open source of information for intruders. Attackers use various
ways to implement attacks, one of which is the dissemination of targeted information. Successful
distribution of targeted (unwanted) information entails the implementation of the attack scenario and
the achievement of the target of the attacker. In this regard, the attackers have an interest in involving
the so-called social networking community leaders (users who have a high level of trust, influence
among a large number of community users) who are able to successfully implement a part of the attack
scenario of the attacker. The article attempts to formalize a generalized algorithm for the distribution
of targeted information in social networks: a set of initial data and the results of the algorithm
work are presented — parameters for implementing attack scenarios, the variation of which will allow
it to be detailed. The technique of protection from the targeted information distributed in social
networks is offered, which will allow to increase the level of protection of personal data and personal
information of users of social networks, reliability of information. The results of the research will
help to prevent threats to information security, to counteract attacks by intruders who often use competitive
intelligence and social engineering methods by applying countermeasures, develop a model
of protection against targeted information and, on its basis, implement special software for integration
into virtual social networks.
