French submarine-maker targeted by hackers
FRANCE, JUL 28 – Hackers claim to have stolen 1 terabyte of sensitive naval data and demand ransom, while Naval Group denies any confirmed breach and calls it a reputational attack.
- On July 26, 2025, France's Naval Group confirmed it 'immediately launched a technical investigation' after hackers claimed to possess 'top secret' data on a dark web forum.
- Attackers threatened to publish confidential data unless Naval Group paid, framing the incident as extortion, with hackers claiming to have breached core systems and demanding payment within 72 hours.
- The breach was posted on DarkForums after threat actor Neferpitou published a 13 GB sample, and an investigation is underway regarding a cybersecurity threat to Naval Group.
- Naval Group insists it detected no intrusion and has filed a complaint with the French judicial authorities, collaborating with the French government and external experts.
- Potential access to naval combat software poses risks, as GlobalData projects the defense sector cybersecurity market will reach $290bn by 2027, experts warn.
