Ukraine's Security Service (SBU) on February 17 said it had disrupted a network of "bot farms" and seized computer and telecoms equipment that were supported by Russian online services in five Ukrainian cities.
Telecommunication platforms were used to create and promote 8,000 fake social-media accounts and groups that were used to spread "fake information about the situation in Ukraine, incite protests, scare the public, send notices of bomb threats at critical infrastructure sites," and troll the accounts of high-ranking officials, the SBU reported on its website on February 17, Radio Free Europe / Radio Liberty (RFE/RL) said.
The operation took place in the capital, Kyiv, and in Kharkiv, Dnipro, Dubno, and Irpin.
Firearms, explosive devices, and narcotics were also distributed using the social-media accounts.
These accounts were registered on the Internet through Russian online services that provided virtual mobile-number services.
Some of the equipment was used to illegally reroute mobile-phone traffic from two "illegally created" mobile carriers that operate in territories that Russia-backed forces control in the eastern part of the country, the SBU said.
While conducting searches in the five cities, the SBU found computer equipment, GSM modems, computer network gateways, and more than 22,000 SIM cards from Ukrainian mobile operators.
The involvement of Russian special services and intelligence bodies in the bot farms is being checked, the SBU said.
