System and method for detecting reputation attacks

A method for detecting reputation cyberattacks in a network, the method being executable by a computing device including a processor communicatively coupled to the network, the method comprising:

• during a first phase:
• crawling, by the processor, the network to identify a plurality of publication sources;
• identifying, in the plurality of publication sources, suspicious publication sources having been used for posting suspicious publications, the suspicious publications for executing reputation cyberattacks in the network;
• identifying, by the processor, in each of the suspicious publication sources, suspicious user accounts having posted the suspicious publications;
• determining, by the processor, among the suspicious user accounts, bot user accounts;
• and
• storing, by the processor, data of the suspicious publication sources and that of the bot user accounts having posted the suspicious publications thereon in a database;
• during a second phase following the first phase:
• obtaining, by the processor, at least one word representing an object of a potential reputation cyberattack;
• crawling, by the processor, the network to identify in-use publications including the at least one word associated with the object of the potential reputation attack;
• determining, by the processor, based on the data in the database, in-use statistics associated with the in-use publications,
• the in-use statistics being indicative of at least one of:
• (i) quantitative characteristics associated with the in-use publications and (ii) how the quantitative characteristics change over time;
• in response to at least one of the in-use statistics exceeding a respective predetermined threshold value, determining, by the processor, (i) a given reputation attack targeting the object;
• and (ii) a respective type of the given reputation attack;
• and
• generating, by the processor, a notification of the given reputation attack including the respective type thereof for transmission of the notification to an entity associated with the object.
