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.

Ukrainian drones strike a plant producing Shahed “brains” in Russia’s city of Cheboksary. Loud explosions and a fire erupted in the town, located approximately 940 kilometers from Ukraine’s Kharkiv, overnight on 9 June.

Ukrainian drones targeted the VNIIR-Progress plant, which produced components for Shahed drones, UMPK kits, and other details for Russian precision-guided weapons.

Ukraine’s General Staff has officially confirmed that the Russian defense industry enterprise, JSC VNIIR-Progress, was struck as part of an operation to degrade the enemy’s capacity to manufacture air-attack systems.

“The facility was confirmed hit by at least two unmanned aerial vehicles, followed by a large-scale fire,” the General Staff has reported.

After the strike, powerful explosions were heard in the city, and the plant halted production, UNIAN writes.

“Two unmanned aerial vehicles crashed on the premises of JSC VNIIR, prompting a decision to suspend operations,” says Oleg Nikolaev, head of Russia’s Chuvashia Republic.

Besides Cheboksary, drone strikes also targeted facilities in Nizhny Novgorod, Tambov, and Voronezh regions. Aviation restrictions were imposed in Kazan, Saratov, and other Russian cities.

A fire and explosion occurred at the Zavolzhsky Motor Plant in Russia’s Zavolzhye, Nizhny Novgorod Oblast, reportedly injuring one worker, according to Astra and official statements from regional labor authorities.

Truck fire erupts in chemical workshop

The Russian news Telegram channel Astra reported on 3 June that the incident took place at night when a long-haul truck caught fire inside a workshop containing chemical substances.

The local Gostrudinspektsiya – a labor conditions inspection body – confirmed the event and said one worker sustained burns covering 10% of the body, and added that all circumstances and potential causes of the workplace incident are being investigated.

Authorities noted the blaze began on 2 June and are awaiting notifications from both the employer and the medical institution treating the injured worker. 

Plant linked to military engine production

The Zavolzhsky Motor Plant produces gasoline and diesel engines and is located in the city of Zavolzhia. Media reports emphasized that the factory manufactures engines used in military equipment. Astra reiterated that point, stating:

“The plant also produces engines for military vehicles.”

Russian publication Kommersant previously reported in 2003 that the plant had received a state contract to develop a line of competitive multipurpose diesel engines ranging from 2.2 to 3.4 liters in displacement. At the time, the plant’s director claimed the new engines would be reconstructed versions of the ZMZ-514 and suitable for a range of vehicles, including off-road models, class-D vehicles, 4-ton trucks, and military hardware.
