Ukrainian military intelligence cyber specialists have carried out a powerful operation against Russian authorities in occupied Crimea. According to RBC-Ukraine’s intelligence sources, the cyberattack lasted several days and paralyzed the entire digital infrastructure of the occupation administration.

It began with a powerful DDoS assault that took down the occupiers’ government services. While panic spread in Crimea and technicians scrambled to identify the source of the outage, Ukrainian hackers had already infiltrated the electronic accounts of the so-called “authorities.” And that was just the beginning.

100 terabytes stolen, systems destroyed

The Ukrainian Defence Intelligence has gained access to the occupiers’ key digital systems:

•  DIALOG,
• SED,
• Delo,
• accounting systems including 1C:Document Management”, Directum, and ATLAS.

In just two days, over 100 terabytes of classified information were downloaded. Among the documents were files marked as top secret, including data on military facilities and logistics for supplying Russian troops.

After completing the operation, HUR specialists destroyed all the occupiers’ administrative servers, at both regional and district levels. These structures have effectively lost access to their documents, databases, and internal communications.

Panic in Moscow, chaos in Crimea

“So much data was extracted that we’ll soon uncover plenty of sensational details about Russian crimes in Crimea. Special thanks for the assistance goes to the deputy minister of health of the occupation government, Anton Lyaskovsky,” an intelligence source told RBC-Ukraine with irony.

Moscow has already labeled the operation as “elements of hybrid warfare.” Meanwhile, the so-called “Ministry of Internal Policy” of Crimea has admitted that some services remain offline. However, the true scale of the destruction is only beginning to come to light.

Keith Kellogg got an uncomfortable look at how Western sanctions on Russia are failing. During his visit to Kyiv, the US Special Representative to Ukraine examined Western-made electronics that Ukrainian intelligence pulled from destroyed Russian weapons—the same components fueling attacks on Ukrainian cities.

The exhibition was coordinated by the War&Sanctions portal of the Main Intelligence Directorate, working alongside the Defense Forces of Ukraine and the Kyiv Research Institute of Forensic Expertise. The display featured components extracted from destroyed or captured Russian weaponry by Ukrainian military intelligence personnel.

Among the items presented to Kellogg were Western elements found in Iranian-Russian Shahed kamikaze drones, also known as “geranium” drones, and Russian “gerbera” drones. These weapons systems have been consistently deployed against civilian targets in Ukraine.

But the problem runs deeper than drone components. Ukrainian analysts identified precision microelectronics critical for manufacturing high-accuracy weapons systems. Russia’s defense industry acquired these through what intelligence officials call “gray schemes”—unofficial networks designed to bypass sanctions.

“The international community must strengthen control over compliance with sanctions imposed on Moscow,” said Cipher, a Main Intelligence Directorate serviceman. “Manufacturers should take a more responsible approach to controlling their products in international markets.”

Head of Ukraine’s Defense Intelligence Kyrylo Budanov also warned Kellogg during their meeting in Kyiv that Russia’s war ambitions extend far beyond Ukraine and are projected to last until 2036, including preparations for a major conflict not only against Ukraine but also NATO. 

Earlier, President Zelenskyy highlighted a significant loophole in international sanctions that allows Russia to continue producing its nuclear-capable Oreshnik intercontinental ballistic missiles using Western technology. 

In 2024, Russia increasingly relied on North Korean KN-23 ballistic missiles to strike Ukraine, while analysis of missile fragments revealed that these weapons contain significant Western-made electronic components, primarily produced by companies from the US, the Netherlands, the UK, and Switzerland, some manufactured as recently as 2023.

These foreign parts include crucial guidance system circuitry without which the missiles could not function, highlighting that the missiles are reliant on imported Western technology despite sanctions.

Experts believe China acts as an intermediary in supplying these components to North Korea, raising concerns about loopholes in export controls and the illicit trade fueling Russian missile capabilities.

Kyrylo Budanov, the head of Ukraine’s Defense Intelligence, passed alarming information to US Presidential Special Representative Keith Kellogg during their meeting in Kyiv. Russia is preparing for a major war, not only against Ukraine but also against NATO. 

The meeting was also attended by the Commander-in-Chief of the Armed Forces of Ukraine, Oleksandr Syrskyi, the Chief of the General Staff, Andrii Hnatov, and other intelligence officials. The American side was briefed on an updated assessment of the operational situation and the Kremlin’s plans for 2036.

“The Kremlin’s imperial ambitions are not limited to Ukraine. They encompass all of Europe. However, with US support, we are capable of stopping Russia and nullifying its military potential,” Budanov emphasized.

The head of the intelligence agency thanked the US for its assistance and stressed, “Russia respects only strength,” and that only through strong resistance can Ukraine achieve a true and lasting peace.

Earlier, US President Donald Trump, frustrated by fruitless “pleasant talks” with Russian leader Vladimir Putin on the war in Ukraine, issued an ultimatum to Moscow. He said that if the Kremlin doesn’t reach a peace agreement within 50 days, the White House will impose 100% tariffs on Russia. This effectively gives Putin 1,5 months to continue killing Ukrainian civilians. Trump also did not clarify what would happen if Moscow refuses to sign any deal with Kyiv. 

Later, former Russian President Dmitry Medvedev openly mocked Trump’s statements, saying the Kremlin is indifferent to Washington’s new threats.

While Moscow is busy relentlessly attacking Ukraine, gas pipelines are blowing up inside Russia itself. According to Ukrainian Defense Intelligence sources, a powerful explosion occurred in the city of Langepas, located in the Khanty-Mansi Autonomous District, damaging a major section of a large trunk gas pipeline, UNIAN reports. 

This pipeline supplied gas to Russia’s defense industry facilities in the Chelyabinsk, Orenburg, and Sverdlovsk oblasts. The destroyed section had an annual throughput capacity of 2.6 billion cubic meters.

“With the price of 1,000 cubic meters of gas at around $350, the immediate damage alone amounts to at least $1.3 million,” the source emphasizes.

At the time of the explosion, about 4.1 million cubic meters of gas were flowing through the pipeline. Due to the difficult, swampy terrain, repairs will take at least a month. This will temporarily reduce supply by 25 million cubic meters, potentially leading to indirect losses of up to $76 million.

Local media writes that residents were “deeply concerned” by the “powerful bangs.” Emergency crews and repair teams quickly arrived at the scene.

Ukrainian intelligence reminds that “Western Siberia feeds Moscow,” but Siberians are dying on the front lines for the Kremlin’s interests.

“When locals begin to actively demand their own independence… such ‘mysterious explosions’ will stop,” the source notes.

Earlier, the Ukrainian Defense Intelligence identified dozens of Russian companies involved in producing the missile, most of which remain unsanctioned.

Its War & Sanctions platform published a list of over 70 Russian companies manufacturing Kh-101 components. These companies still have access to Western equipment and technology, enabling Russia to replenish its missile stockpiles and continue targeting civilian infrastructure.
