Abstract: One embodiment provides a method including identifying malicious information spreading in an information-exchange network; classifying at least one topic of the malicious information; determining a potential sub-network for future spread of the malicious information based on the at least one topic classified; and attenuating a potential future spread of the malicious information via at least one of: automatically propagating a countervailing message to the potential sub-network; and prompting manual intervention for propagating a countervailing message to the potential sub-network. Other variants and embodiments are broadly contemplated herein.

Abstract: Methods and arrangements for controlling a spread of malicious information in a network. A viral spread of information is tracked, in a network comprising interconnected nodes. Malicious information in the viral spread of information is identified. A topic-specific sub-network of nodes prone to be affected by the malicious information is predicted, and the effect of the malicious information at the sub-network of nodes is neutralized, via initiating a spread of neutralizing information to the sub-network of nodes. Other variants and embodiments are broadly contemplated herein.
