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.
