Ukraine’s drone strikes on Russian tech giant Yandex thinned out social media bots, Ukrainian President Volodymyr Zelenskyy said on 12 October. Network data do show Yandex’s automated traffic collapsing after the strikes. Disinformation researchers say that traffic is search crawling, not trolls. A Ukrainian social media monitor told Euromaidan Press its own data show no clear drop in bot activity either.

Russian influence operations are a live threat to European votes. In August, the Matryoshka network fabricated news clips aimed at Sweden’s general election. German and French authorities flagged the same network targeting Germany’s local votes and French presidential hopeful Gabriel Attal. A way to switch such networks off would hand allies a new tool, which is why the claim needs testing.

The president’s claim

Addressing the Warsaw Security Forum by video link, Zelenskyy said that once Ukraine began answering Russia’s operation against Ukrainian data centers and its strikes reached Yandex, many social media platforms suddenly became a little easier to breathe on.

Many people noticed less hatred, discord, and provocation because there were fewer bots, he said. It was quite clear where those bots came from, he noted. Their disappearance once Yandex went down proves again that Europe is not the source of the problems, he added.

Lithuanian Prime Minister Mindaugas Sinkevičius said at the same forum that allies should ask Zelenskyy to strike more data centers in Russia, answering a question on how to protect their elections from interference.

Three data centers in four days

Drones first hit Yandex’s data center in Sasovo, Ryazan Oblast, on 8 October. Yandex said it shut the site down completely. The next day, a strike on its Kaluga site completely disabled several modules, the company said. Yandex calls Kaluga its largest data center, Russian science outlet T-Invariant noted.

Ukrainian drone maker Fire Point said its FP-1 long-range drones carried out that strike.

After the first strike, on Sasovo, a source at Yandex summed up the mood for The Bell: “Things are rotten. We keep working.”

Overnight on 11 October, drones hit the third site, in Vladimir. Yandex said it fully halted that data center too. Vladimir Oblast Governor Aleksandr Avdeev acknowledged an attack on “infrastructure” near the city. It started a fire and cut power to two substations serving 5,000 residents, he claimed.

Dima, have you tried turning it off and on again?

What the traffic data show

Automated web requests from Yandex’s network fell to 0.4% of their two-week peak after the third strike, Cloudflare Radar data showed, Cybernews reported. That chart counts automated requests to websites, mostly from Yandex’s own search crawlers. It does not count social media posts.

The chart “has nothing to do with social media,” the Russian opposition analysis group Antibot4navalny wrote.

To those implying that Kremlin-controlled social media bot/troll farms became silent after Ukraine hit a Yandex data center, posting this CloudFare chart ( radar.cloudflare.com/bots/as13238 ):Hate to disappoint you all

Russia’s overall bot traffic last week looked much like any other week. Yandex’s own figure began recovering on Sunday. Covert troll farms usually hide behind residential proxies, hacked devices, virtual private networks (VPNs), and Western cloud providers, the outlet added.

What Ukrainian social media shows so far

Yevhen Luzan tracks Ukrainian social media sentiment as an analyst at the Ukrainian nonprofit CAT-UA. Its daily reviews sample about 500 random posts. On 11 October, that sample showed an unusually small share of posts criticizing Ukraine’s authorities, he told Euromaidan Press. Accounts showing signs of bot activity made up only a few tenths of a percent of that criticism. That is within the margin of error.

The same day, though, US President Donald Trump’s deal for Russian diesel supplies dominated Ukrainian feeds. Luzan said a rally-around-the-flag effect could explain the shift, as outrage at Washington crowded out domestic stories.

“To state it definitively and draw a cause-and-effect link from this correlation would be too bold,” he said.

Across the wider pool of about 10,000 daily mentions, CAT-UA sees no significant drop in posting activity in recent days. The curve shows only the usual rises and dips around the start and end of the week, Luzan said.

“For now, even a hypothetical drop in bot farm activity dissolves entirely in the natural fluctuations of the information space,” he said.

How a crawler chart became a bot story

The claim that Russian social media bots fell by half is unproven and built on a misread chart, disinformation analyst Joohn Choe concluded in a fact-check. It traces back to an 8 October post by security researcher Jeremiah Fowler. That post said Russian bot traffic had dropped to 49%. On 11 October, radio reporter Jamie Dupree spread it on X. Tom’s Hardware then ran it under a headline calling the crawler traffic “Russian disinformation bot traffic,” wording it has since changed.

Ukrainian military analyst Tatarigami claimed that Texas separatist accounts with identical “Veteran, Christian, Father, MAGA” bios had gone quiet. He said Quebec separatists and Polish anti-EU accounts went quiet alongside them.

Polish military analyst Jarosław Wolski claimed that AfD’s online support fell 56%, posting a chart without naming its source. Another X user said “Polish” bots had vanished.

Zderusyfikowany internet (ukraińskie trafienia w centra Yandexa) nagle objawia cuda w socjalach: poparcie dla AfD w socjalmediach spadło o 56%. Mniej "polskich" kont szczujących na Ukraińców, mniej "ukraińskich" szczujących na Polaków, poparcie w sieci dla MAGA gwałtownie spadło… pic.twitter.com/zi4rwqNR9I

Ukrainian strikes hit a site housing Russian troops in Khrustalnyi, a city in Russian-occupied Luhansk Oblast, overnight on 12 October, according to local reports. Satellite fire data recorded blazes at a former motor depot there, in an area Russia once used as a logistics base for its offensive in the region.

Russia keeps attacking in Ukraine’s Donetsk Oblast and strikes Ukrainian cities and power plants every day. Its offensive depends on troops, ammunition, and fuel moved through occupied Ukraine, so strikes there reach the supply chain behind the front.

Fires at a former motor depot in occupied Khrustalnyi

Ukrainian forces launched heavy strikes around Khrustalnyi in eastern Ukraine overnight, the Ukrainian monitoring channel Exilenova+ reported. It counted three separate fires and one large blaze, and said local residents reported a hit on a site where Russian troops were based. Ukraine’s military had not officially commented on the strike by the publication time of this article on 12 October.

Ukraine’s Defense Forces are carrying out massive strikes in the area of occupied Khrustalnyi in Luhansk Oblast. Three separate fire hotspots and a large-scale blaze have been reported.

NASA’s Fire Information for Resource Management System (FIRMS), which tracks active fires by satellite, shows blazes at a former motor transport enterprise and an industrial zone in Khrustalnyi, Ukrainian military outlet Militarnyi reported. Three fire hotspots appeared there at 01:10 and spread by 02:07, the outlet said.

Ukraine also hit the site on 16 June 2022, striking an ammunition depot there, and local residents then heard secondary detonations, Militarnyi said. The site served as an important logistics base for Russia’s 2nd Army Corps in its offensive on Sievierodonetsk and Lysychansk, two cities in Luhansk Oblast, the outlet added.

Explosions at a Crimean airfield Russia used to launch drones overnight

Drones attacked occupied Crimea from the evening of 11 October into the night, and Russian air defenses, including mobile fire groups, fired across the peninsula, Krym.Realii, Radio Liberty’s Crimea service, reported. Explosions sounded in Simferopol, Feodosiia, and Yevpatoriia, among other places, the Crimean monitoring Telegram channel Crimean Wind said, according to the outlet.

Subscribers told the channel about a series of explosions and a glow at Russia’s Hvardiiske military airfield in Simferopol district as air defenses fired. Krym.Realii said neither Ukraine’s nor Russia’s military had commented and that it could not verify the reports independently.

Overnight, Russia also launched attack drones at Ukraine from several directions, including Hvardiiske in occupied Crimea, Ukraine’s Air Force reported.

Ukraine’s General Staff said in August that a 3 August strike on the Hvardiiske airfield destroyed nine aviation fuel tanks and damaged two aircraft hangars.

Ukraine keeps hitting Russian rear areas in occupied territory

On 10 and 11 October alone, the General Staff reported hitting a Russian repair base and supply depots in occupied Luhansk Oblast, along with Russian troop concentrations near Lysychansk and two other towns there.

Ukraine has also kept up its campaign of so-called middle strikes, drone attacks on Russian supply lines in occupied territory beyond the front. French mapper Clément Molin counted 770 confirmed drone hits on Russian trucks in September, up from 630 in August, with the strikes concentrated on supply routes running through occupied southern Ukraine into Crimea.

Strikes on troop sites and airfields far behind the front leave Russia fewer safe places in occupied territory to house troops and launch drones, adding to the battlefield losses Ukraine’s drones already inflict.

Ukraine has been striking the launchers Russia uses to fire ballistic missiles at its cities, Ukrainian Defense Minister Yevhenii Khmara told journalists. He said the strikes have already disrupted some Russian attack plans, but supplies of anti-ballistic interceptors still fall short of the threat.

Russia strikes Ukraine’s cities and power grid with drones and missiles every day as it prepares to leave civilians without power and heat this winter. Ballistic missiles are the part of that barrage Ukraine still struggles to stop, so every launcher put out of action before it fires means fewer missiles to intercept.

Iskander and S-400 launchers hit since September

Ukrainian forces hit eight launchers used for ballistic strikes on Ukraine in September and early October, destroying three and damaging five, Khmara said. They belonged to Russia’s Iskander tactical missile systems and S-400 air defense systems, he added. Such strikes have already forced Russia to cancel or change planned ballistic attacks, the minister said.

The S-400 was designed to shoot down aircraft and missiles, but Russia also uses it to fire ballistic missiles at Ukrainian cities, including Kyiv. In mid-September, Ukraine reported hitting two S-400 launchers near Vygonichi in Russia’s Bryansk Oblast. Russia had used the same systems against Kyiv the night before.

On 23 August, Ukrainian President Volodymyr Zelenskyy said Ukrainian forces had hit an Iskander launcher near the border. He described it as part of a separate operation to hunt nearby launch positions and linked the tactic to low stocks of anti-ballistic missiles.

Strikes on launchers while interceptors stay scarce

Khmara called the launcher strikes Ukraine’s asymmetric response to a ballistic threat that remains critical.

“Existing and potential supplies of missiles for anti-ballistic defense are not enough to fully cover this threat,” he said.

Instead of waiting for large long-term contracts, the Defense Ministry is looking for missiles in partners’ available stocks to speed up transfers, Khmara added. “We need dozens and hundreds of missiles, not one-off deliveries,” he stressed.

Meanwhile, Russia significantly cut its 2026 state orders for Kinzhal air-launched ballistic missiles, Ukraine’s military intelligence said on 12 October. It redirected the production capacity, components, and raw materials to Iskander-M ballistic missiles, the agency added.

Russia’s missile and drone attacks continue

Overnight on 12 October, Russia attacked Ukraine with a Kh-59 guided missile and 121 attack drones, 76 of them jet-powered, Ukraine’s Air Force reported. Air defenses downed or suppressed 89 drones, but strikes hit 15 locations, and the attack was still going on in the morning.

In the week to 11 October, Russia hit Ukraine’s power generation and transmission facilities more than 200 times and its gas and oil sites 17 times, Zelenskyy said. Russian attacks that week killed more than 150 people and injured more than 700, he added.

Jet-powered drones are still the main problem for Ukraine’s air defense. It stops more than 90% of slower propeller-driven Shaheds, compared with about 55% for the jet ones.

Ballistic missiles have struck Kyiv repeatedly this autumn. On 24 September, Russian ballistic and hypersonic missiles damaged a maternity hospital in the capital. On 7 October, a Russian missile barrage killed 22 people in Pryluky, Chernihiv Oblast.
