On 12 June, hacker groups InformNapalm and Militant Intelligence released several leaked documents obtained from JSC Russian Helicopters—a major Russian helicopter manufacturing company. According to the groups, they obtained all of the company’s international contracts, supply routes, and payment documents of the company revealing extensive foreign cooperation with Russia’s defense sector.

InformNapalm stated that the cyber operation coincided with Russia’s national holiday.

“Today, 12 June, the terrorist state celebrates ‘Russia Day’,” the group wrote.

The leak was described as symbolic “greetings with a noose” for Russia, meant to expose the vulnerabilities of its military-industrial complex.

InformNapalm denounced the White House’s currently consistent weak stance towards Moscow, pointing out that the US Cyber Command halted cyber operations against Russia during Donald Trump’s presidency. As a result, the group said, “volunteers and enthusiasts” now carry out cyber operations against Russian targets.

Wider cyber operation

The report says that the cyberattack was part of a broader campaign labeled OpsHackRussia’sDay, which, according to the hackers, targeted a network of Russian corporations tied to the defense industry. JSC Russian Helicopters, a holding that unites all Russian helicopter manufacturers, is among the breached entities. The company operates under Oboronprom, itself a subsidiary of the state-owned conglomerate Rostec.

“As a result of the hack, [JSC Russian Helicopters’] all international contracts, supply routes, bank receipts, accounts from India and other countries were exposed, including embassy archives and Ministry of Defense documents,” InformNapalm wrote.

Documents reportedly mention India, Egypt, Algeria, Indonesia, Laos, Cuba, Kenya, and Uganda. The leaked content includes full detail on tenders, clients, correspondence, staffing schedules, travel routes, banking relations, and coordination with the Russian Ministry of Industry and Trade.

Military logistics and foreign involvement

Among the disclosed data, Egypt is named as a logistics hub for Mi-17V-5 maintenance, while Bulgaria appears in supply chain and repair cooperation schemes, according to the report. Other nations named include Azerbaijan and North Macedonia. The documents mention entities like RAWAN HANS in India and detail procurement pathways through Algeria and Indonesia, often using third-country routes.

Hackers promise more data, predict fallout

The publication claims the leak will lead to serious disruptions:

“This release will bring major problems to their defense sector and expose their international customers and partners who tried to stay hidden.”

The group anticipates “contract terminations, sanctions tightening, and global scandals.”

According to InformNapalm, part of the obtained information is already in use for Ukraine’s defense, and more data will be published over time.

A Ukrainian drone attack on Bryansk airport overnight on 5–6 June destroyed a Russian Mi-8 helicopter and damaged a Mi-35, according to Russian news Telegram channel Astra. There are signs of the long-lasting military use of the civilian facility, Militarnyi notes.

Astra reported that the Ukrainian UAVs targeted the territory of the Bryansk International Airport last night located in the village of Oktyabrskoye near Bryansk. As a result of the strike, a Mi-8 helicopter was completely destroyed and its ammunition detonated. A Mi-35 military helicopter was also partially damaged.

According to Astra’s sources within the Russian Ministry of Emergency Situations, the strike also damaged the airport’s administrative building and the local rescue service facility. There were no casualties reported. Several dozen workers were evacuated from the nearby Ozon warehouse due to the explosions.

Video footage published by several Telegram channels showed secondary explosions after the initial impact. 

Additionally, last night, the Ukrainian drones struck an oil depot in Engels in Russia’s Saratov Oblast, and targeted Ryazan’s Dyagilevo airbase, and the Progress plant in Michurinsk, Tambov Oblast — a facility involved in producing components for rocket and aviation systems. 

Signs of Bryansk airport’s long-term military use of the airport

Militarnyi cited OSINT analysts from the Oko Hora group, noting that satellite imagery showed two objects — likely helicopters — regularly changing positions at the airfield, indicating long-term deployment and military use of the civil airport.

Militarnyi added that what exactly Russia stored in these airport buildings remains unclear, but the power of the explosions and the detonation observed by eyewitnesses suggest that an ammunition depot may have been present, possibly leading to the destruction and damage to Russian aircraft.

Today, there are a lot of interesting updates from the Kupiansk direction. Here, along the Oskil River near Kupiansk, Ukrainian special forces just carried out one of the boldest operations of the war.

In a surprise helicopter raid deep behind Russian lines, they landed undetected and tore through dugouts, safe houses, and staging zones, shattering Russian preparations before their offensive could even begin.

Hidden danger of Kharkiv Oblast town

The Russian forces in this area maintain a very thin bridgehead on the west bank of the Oskil River, where the control of the town of Dvorichna allows them to accumulate and deploy forces across the river.

Russians plan to use this bridgehead to tactically outflank Ukrainian forces in Kupiansk from the north, as well as to use it as a launching pad to link up with their other offensive in Kharkiv.

The Ukrainians understand that the Dvorichna bridgehead will be a key staging ground for the Russian summer offensive in Kharkiv, and know that they must act quickly to undermine any future Russian effort here.

The flaw in the river

The primary Russian weakness here is that their forces must cross the Oskil River by boat to reach their bridgehead on the western bank, which significantly complicates their logistics. This prevents them from deploying large numbers of heavy weapons such as anti-tank guided missiles or MANPADS.

The lack of man-portable air defenses makes the Russian bridgehead highly vulnerable to any aerial operations that the Ukrainians could conduct.

Subsequently, the Ukrainian special operations forces command devised a daring and unconventional plan, to conduct the first air assault operation in the war in over three years.

They planned to fly over Russian lines and deploy several teams of special forces in the rear of the enemy, where they would conduct raids, gather intelligence, and direct fire onto concealed Russian deployment points.

Ghosts in the trees

The Ukrainian Special Forces involved in this operation were deployed using American UH-60 Black Hawk helicopters, flying low to avoid being detected by the Russians.

Penetrating deep behind Russian lines, the helicopters were able to land and dismount several dozen Ukrainian operators before returning safely to friendly territory.

Once on the ground, the Ukrainian troops moved quickly and with purpose. After reaching their targets, they launched a series of highly effective and deadly raids against Russian forces. They cleared forest belts and residential areas of enemy soldiers who had been preparing to cross the river.

Russian troops were caught completely off guard, never expecting an attack from their rear. Several dugouts were quickly encircled, and numerous Russian soldiers were captured in the confusion.

Taking full advantage of surprise and terrain, Ukrainian operators concealed themselves in forested areas, waiting for small Russian infantry groups that were either sent to find them, or were moving to new positions completely unaware.

These ambushes were swift and lethal, as the Ukrainians eliminated enemy soldiers at point-blank range using small arms, all while remaining undetected in the dense cover of the forest.

The escape corridor

The high level of coordination and preparation of the Ukrainian forces included several armored vehicles, meant to arrive near a designated exfil point to quickly evacuate the operators. This point was chosen carefully, as it had the least amount of frontline activity, and no Russian bridgehead, making it the safest route for the job.

The Ukrainians moved through the dense forests behind the Dvorichna bridgehead and avoided areas with larger concentrations of Russian soldiers.

The Ukrainian special operators, with intelligence gained from captured Russians, enabled the Ukrainian drone operators to identify large Russian strongholds standing in the way of the Ukrainian exfiltration.

Artillery crews and heavy drone bombers were deployed, leading to the decimation of these Russian troops.

This focused fire established a corridor for the Ukrainian special forces to safely traverse the forests and reach the western bank of the river, where MaxPro armored vehicles awaited to exfiltrate them back to safety.

Operators left behind: the shadow war begins

Overall, the Ukrainians achieved the impossible, carrying out the war’s first air assault operation in over three years, allowing them to strike deep into Russian-held territory, inflict serious losses, and gather critical intelligence.

Notably, it is highly likely that not all Ukrainian operators exfiltrated from behind Russian lines.

According to special forces doctrine, these operators will be able to gather intelligence, set up and train further resistance networks, and conduct a deadly guerrilla warfare with sabotage and liquidations of top Russian commanders.

Russia is going to go all-in this summer, and the Ukrainians are positioning themselves to take every advantage they can to repulse it.
