The Russians are back — on Twitter.

The Alabama Senate candidate who ousted Trump-backed Luther Strange in a GOP primary last month may have been the latest victim of a Russian cyber campaign to infiltrate the US political system.

Controversial former judge Roy Moore gained 20,000 Twitter followers over the weekend — more than 1,100 of them bearing Russian language names and descriptions, according to The Montgomery Advertiser.

Moore’s campaign denied they had anything to do with the Twitter invasion and blamed the whole bot army offensive on Doug Jones, his Democratic rival.

“Doug Jones and Democrat operatives are pulling a political stunt on Twitter and alerting their friends in the media,” the Moore campaign said Monday in a statement, obtained by the Advertiser.

“It’s not surprising that they’d choose the favorite topic of MSNBC and the Fake News outlets – the Russia conspiracy.”

A campaign spokesman for Jones, the Democratic candidate, called the reports of Moore’s fake followers “bizarre” and denied they had any involvement in the bot surge.

“I can confirm the Jones campaign has not purchased and would not purchase any social media followers,” the spokesman told the paper.

The bot accounts appeared to mimic real supporters of Moore’s candidacy for US Senate.

Twitter removed most of the fake accounts by Monday evening.

The social network is still grappling with the issue of fake accounts and influence campaigns after the 2016 presidential election.

The US intelligence community and the Senate Intelligence Committee have determined that Russia launched a campaign to interfere with the election during last year’s campaign season.
