The U.S. Department of Justice said it disrupted a Russian propaganda campaign using fake social media accounts, powered by artificial intelligence, to spread disinformation in the U.S. and other countries.

The bot farm used AI to create profiles impersonating Americans on X, formerly known as Twitter, and to post support for Russia's war in Ukraine and other pro-Kremlin narratives.

US officials say they have taken action against an AI-powered information operation run from Russia, including nearly 1,000 accounts pretending to be Americans.

The accounts on X were designed to spread pro-Russia stories but were automated “bots” - not real people.

In court documents made public Tuesday the US justice department said the operation was devised by a deputy editor at Kremlin-owned RT, formerly Russia Today.

RT runs TV channels in English and several other languages, but appears much more popular on social media than on conventional airwaves.

The U.S. Department of Justice recently seized control of two internet domains and searched 968 accounts on the X social media platform, which it accused of helping spread disinformation for the Russian government.

The seizures were part of an FBI investigation into an alleged artificial intelligence-enhanced social media bot farm that has created hundreds of fake social media profiles purportedly of U.S. residents, according to a June 27 search warrant affidavit. The affidavit says the accounts promoted messages that support Russian government objectives.
