NATO is investigating the leak of data reportedly stolen from a European missile systems firm, which hackers have put up for sale on the Dark Web, according to a published report.
The leaked data includes blueprints of weapons used by Ukraine in its current war with Russia.
Integrated defense company MBDA Missile Systems, headquartered in France, has acknowledged that data from its systems is a part of the cache being sold by threat actors on hacker forums after what appears to be a ransomware attack.
Contradicting the cyberattackers' claims in their ads, nothing up for grabs is classified information, MBDA said. It added that the data was acquired from a compromised external hard drive, not the company's internal networks.
NATO, meanwhile, is "assessing claims relating to data allegedly stolen from MBDA," a NATO official told Dark Reading on Monday.
"We have no indication that any NATO network has been compromised," the official said.
MBDA acknowledged in early August that it was "the subject of a blackmail attempt by a criminal group that falsely claims to have hacked the company's information networks," in a post on its website.
The company refused to pay the ransom and thus the data was leaked for sale online, according to the post.
Specifically, threat actors are selling 80GB of stolen data on both Russian- and English-language forums with a price tag of 15 bitcoins, which is about $297,279, according to a report from the BBC, which broke the news about the NATO investigation Friday. In fact, cybercriminals claim to already have sold data to at least one buyer.
NATO is investigating one of the firm's suppliers as the possible source of the breach, according to the report. MBDA is a joint venture between three key shareholders: AirBus, BAE Systems, and Leonardo. Though the company operates out of Europe, it has subsidiaries worldwide, including MBDA Missile Systems in the United States.
The company is working with authorities in Italy, where the breach occurred.
MBDA reported $3.5 billion in revenue last year and counts NATO, the US military, and the UK Ministry of Defense among its customers.
Classified Info & Ukraine
Hackers claimed in their ad for the leaked data to have "classified information about employees of companies that took part in the development of closed military projects," as well as "design documentation, drawings, presentations, video and photo materials, contract agreements, and correspondence with other companies," according to the BBC.
Among the sample files in a 50-megabyte stash viewed by the BBC is a presentation appearing to provide blueprints of the Land Ceptor Common Anti-Air Modular Missile (CAMM), including the precise location of the electronic storage unit within it. One of these missiles was recently sent to Poland for use in the Ukraine conflict as part of the Sky Sabre system and is currently operational, according to the report.
This might provide a clue about the motive of threat actors; advanced persistent threats (APTs) aligned with Russia began hitting Ukraine with cyberattacks even before the Russian official invasion on Feb. 24.
After the conflict on the ground began, threat actors continued to throttle Ukraine with a cyberwar to support the Russian military efforts.
The sample data viewed by the BBC also included documents labelled "NATO CONFIDENTIAL," "NATO RESTRICTED," and "Unclassified Controlled Information," according to the report. At least one stolen folder contains detailed drawings of MBDA equipment.
The criminals also sent by email documents to the BBC including two marked "NATO SECRET," according to the report. The hackers did not confirm whether the material had come from a single source or more than one hacked source.
Nonetheless, MBDA insists that the verification processes that the company has executed so far "indicate that the data made available online are neither classified data nor sensitive."
