Russia-linked bot networks kept their weekly rhythm after drone strikes on three Yandex data centers—disinformation monitor LetsData

The claim that strikes on Russian tech giant Yandex thinned out social media bots finds no support in the networks tracked by Ukrainian disinformation-monitoring company LetsData, co-founder Ksenia Iliuk told Euromaidan Press on 13 October. She cautioned that the strikes may still have affected networks outside the company’s view.

At the Warsaw Security Forum, Lithuania’s prime minister suggested allies should ask Ukraine to strike more Russian data centers because that might help protect European elections from foreign interference. Bot networks are one tool of that interference, so whether the strikes mute them carries weight well beyond Ukraine.

No drop in the networks LetsData tracks

Drones hit Yandex data centers in Sasovo and Vladimir between 8 and 11 October. Ukrainian drone maker Fire Point said its FP-1 drones struck Yandex’s Kaluga site in between. On 12 October, Ukrainian President Volodymyr Zelenskyy told the Warsaw Security Forum that once Ukraine’s response reached Yandex, social media had fewer bots.

LetsData checked X and Facebook, where bot networks usually stand out clearly, Iliuk said. Its analysts looked at networks attributed to Russia’s influence ecosystem. Among them are groups of X accounts spreading domains from what she called a new wave of Doppelgänger, a Russian campaign that clones real news sites.

Those networks look unaffected, Iliuk said. None of them has stopped posting or broken its usual rhythm, she added. Some are slightly less active, but LetsData’s analysts say that is typical for them. The networks run on a weekly cycle, and the check fell in the part of the week when they post less.

A network that jumped from Germany to Ukraine

LetsData worked with two samples. One covers accounts that systematically target Ukraine, Moldova, and Armenia. The other covers bot networks the company has followed for some time that keep changing their target audience, so they have no fixed country.

About two weeks ago, one network from that second sample wrote about elections in Germany and spread fake Die Welt sites, she said. It now posts about mobilization in Ukraine and shares a fake site of Ukrinform, Ukraine’s state news agency.

What the check can’t see

The company can compare only within networks whose usual behavior it knows, Iliuk said. Checking the whole internet is impossible because the scale is colossal, she said. A Cloudflare chart that circulated as evidence counted automated web requests from Yandex’s network, including its search crawlers, not social media posts, Cybernews reported.

So the networks LetsData follows show no impact, Iliuk said. That does not mean the strikes had no effect at all, she noted. They may have shown up in networks the company isn’t tracking now. LetsData will keep watching and report other signals if they appear.
