Naval Group denounces an attempt to destabilize after the claim of an attack on its computer networks

In a note published on July 24, the Defense Intelligence and Security Department [DRSD] said that it had noted a “high” but “stable” number of interference acts targeting the industrial and technological basis of French defense [BITD]. Meanwhile, Contrary to what one might think, the first threats is not computer science but human. Moreover,

“The number of so -called ‘human’ attacks [chantage, faux entretiens de recrutement, vols d’ordinateurs, tentatives de débauchage, etc.] has continued to grow in recent years. Furthermore, This trend is confirmed in 2024 [36 % des atteintes] Although in lower proportion compared to the year 2023 [45 %] “. Nevertheless, Advocals the DRSD, for whom these threats are mainly because of China … Moreover, as well as, in the European naval group denounces attempt destabilize markets, of the” main competitors “of the French BitD. In addition,

Physical damage [sabotages, intrusions, dégradations] represented 18 % of interference in 2024. Nevertheless, According to the DRSD, the “protest actions of the ultra -ke movement continued to intensify”. Therefore, Next come “capital predation” on technological skills [13 % des faits]the use of the right to strategic purposes [9 %] and reputational threats [6 %]. Therefore,

As for computer attacks [15 % du total des atteintes constatées]their number increased by 50 % compared to 2023. Moreover, “The vast majority of them are perpetrated by the cybercriminal ecosystem which has retained its conventional infection vectors to penetrate the information systems of its targets in the defense industry”. For example, advances the DRSD, referring to the so -called “hammering” techniques, to ransom and attacks by denial of service. Nevertheless,

In most cases. Similarly, these cybernetic attacks have targeted the naval group denounces attempt destabilize institutional sites of companies involved in the supply of military equipment to Ukraine. Therefore, They “have undermined in particular the aeronautical and new sectors
Information and communication technologies, ”specifies military counterattack. Consequently,

That said, in which category will the case are that concern Naval Group currently? For example, Thus. on July 23, a hacker assured that he was in possession of a highly sensitive data teraoctet after introducing himself into the digital networks of the naval manufacturer. And he gave a 72 -hour ultimatum to the latter to pay him a ransom … Otherwise, he will broadcast these confidential documents for free via the “Dark Web”.

Publicing such information without trying to monenayer may seem surprising … hence questions about the real motivations of this computer hacker. In any case. on July 25, a few hours before the expiration of his ultimatum, he gave an overview of the data naval group denounces attempt destabilize in question, which would concern, among other things, the user guide for combat management systems for nuclear launchers of machinery and multimission frigates. Only, it was not possible to verify the veracity of your allegations.

For its part, Naval Group confirmed that it had detected a “cybersecurity incident potential”.

“As we take any cyber alert very seriously. have suitable procedures, we immediately mobilized a team of experts related to state services. Investigations are therefore to provide the answer that will be appropriate. In the meantime, one cannot confirm or deny this information, ”explained the industrialist.

In view of its importance by its involvement in nuclear deterrence. intense competition on the military naval market, Naval Group is a privileged target for all those who seek to tarnish the image of the French bitd. Also. the industrialist has an alert and reaction center for IT attacks [CERT – Computer naval group denounces attempt destabilize Emergency Response Team]which, in 2024, joined the “Forum of Incident Response and Security Teams” [FIRST] after a demanding procedure.

“Concretely. being part of the First allows, among other things, to better understand the operating modes of the groups of attackers who could harm the interests of Naval Group or its customers, either by industrial spying, or by seeking to reduce our operational availability by acts of cyber-sabotage,” explains the naval manufacturer.

Anyway. on July 26, when the ultimatum was going to expire, Naval Group published a press release to take stock of the situation. Thus. “no intrusion into our IT environments has been detected and no impact on our activities has been reported,” he said. As for the data that has potentially been the subject of a leak. “the authenticity of their provenance and their membership” are being examined by its teams of cybersecurity experts.

In any naval group denounces attempt destabilize case, in view of these elements, Naval Group denounced an attempt at destabilization. And we imagine that each word of its press release has been carefully chosen.

“In an international. commercial and information under tension context, generating an intensification of attempts at destabilization, Naval Group notes being the target of a reputational attack, characterized by the claim of an act of malicious cyber,” read in the press release.

“With regard to the facts noted, the challenges of sovereignty of Naval Group and the need to protect the data of our customers, a complaint was filed to shed light on these acts of maliciousness,” he continues.

This is not the first time that Naval Group has been targeted in this way. When he had just won naval group denounces attempt destabilize the call for tenders relating to future Australian submarines. in 2016, the French industrialist had to face a massive leak of documents concerning the scorpene submarines intended for India, which had opened an investigation. Mediatized by the newspaper The Australian, this case had led him to file a complaint against X.

Finally, it was a “pseudo leaks”, India having classified the case without follow -up a year later. “Suspicions weigh heavily on a European competitor of the French group. who attempted a maneuver for destabilization,” advanced La Tribune in July 2017.
