French defence shipbuilder Naval Group has moved to quell speculation that it has been the victim of a significant cyber breach and extortion hack.
Hackers have already claimed responsibility for an alleged breach, posted on a data leak forum earlier this week with a 72-hour deadline, which purportedly contains information about classified files regarding submarines and frigates, network data, confidential messages and technical documents from 2006 to 2024.
The hackers also reportedly posted a 13 GB data sample as evidence of the breach.
“In a global context marked by international, commercial and informational tensions, with more and more destabilisation attempts, Naval Group has noticed being the target of a reputational attack with the claim of a cyber-malice act,” according to a recent response from the company.
“Considering the facts and the sovereignty issue at stake for Naval Group and the necessity to protect our clients’ data, a complaint has been filed to shed light on these acts.
“In accordance with our cyber security procedures, we immediately launched technical investigations, with the support of a team of cyber security experts and the Naval Group’s CERT, in close collaboration with the French Authorities.
“All our teams and resources are currently mobilised to analyse and verify the authenticity, origin and ownership of the data as quickly as possible.
“At this stage, no intrusion into our IT environments has been detected and there has been no impact on our activities.”
