  • The director of the NSA has confirmed that Mythos, Anthropic’s AI model, has penetrated ‘almost all’ US classified systems. In a matter of hours.

    The director of the NSA has confirmed that Mythos, Anthropic’s AI model, has penetrated ‘almost all’ US classified systems. In a matter of hours.

    Senator Mark Warner revealed on 11 June that General Joshua Rudd, who heads both the NSA and Cyber Command, had told him directly: Mythos “had breached almost all our classified systems, not in weeks, but in hours.” The information, reported by The Economist, has not been officially confirmed by the agencies concerned.

    The test was an authorised red team exercise on the NSA’s networks. It was not a real attack. However, the speed and scale of the breach are said to have exceeded anything previously observed using conventional methods.

    This revelation puts the 12 June decision to cut off access to Fable 5 and Mythos 5 into context. It may not have been just a simple jailbreak. It was a demonstration that a commercial AI model could autonomously compromise the world’s most heavily protected systems.

    The official trigger remains the jailbreak reported by Amazon to the Department of Commerce. Facebook’s former head of security, Alex Stamos, says he examined the data and shared Anthropic’s view: ‘valid results but no unique capability justifying a response of this scale. ”

    But if Rudd’s account is accurate, it changes everything. An AI model built by a San Francisco start-up, capable of breaching the NSA’s defences in a matter of hours. Not using a known exploit. Through autonomous reasoning.

    We’ve gone from ‘AI could become dangerous one day’ to ‘AI has just hacked the NSA during a test’. The question is no longer a theoretical one.

  • ARC Data Shield has caught the attention of Wavestone and Bpifrance as one of the most promising cybersecurity start-ups

    ARC Data Shield has caught the attention of Wavestone and Bpifrance as one of the most promising cybersecurity start-ups

    This recognition means a great deal to us, as it validates a belief we have held since 2022: in the face of the rise in AI-assisted attacks, the protection of critical assets and sensitive networks cannot rely solely on software solutions, which are inherently vulnerable. 🔓

    Our groundbreaking Digital Air Gap network appliance — featuring permanent, patented, 100% electronic hard partitioning — continues to prove its worth with leading organisations. 🌎

    Being recognised by Wavestone and Bpifrance as an outstanding start-up within the French cyber ecosystem is a significant milestone. But above all, it encourages us to go much further. 🚀

    👉 CISO, CIO, cyber experts: if protecting your critical infrastructure against ever more sophisticated threats is a priority for you, we’d be delighted to discuss this with you. 📞

  • SentinelOne’s BDU out, Babuk in

    SentinelOne’s BDU out, Babuk in

    AON researchers demonstrated on May 7, 2025 how a hacker, after exploiting an application flaw, bypassed the SentinelOne EDR’s anti-tamper protection to uninstall the Windows agent and deploy a variant of the Babuk ransomware.
    By exploiting the agent’s unauthenticated upgrade/downgrade, the attacker neutralized all detection, leaving the compromised server at the mercy of malicious encryption.
    SentinelOne was quick to react: local passphrase activated by default, authentication of updates and reinforced installation authorization via its console.


    But, as Stroz Friedberg warns, these patches are no substitute for a defense-in-depth strategy.
    In the face of constantly evolving circumvention methods, regular, isolated (physically offline) backups remain the last bastion of business continuity.

    In addition to instant patches, investing in redundant solutions and frequently testing restoration procedures is now a must for controlling the risk of ransomware.

  • Cyberattack on fintech firm Harvest: disruption and data breach

    Cyberattack on fintech firm Harvest: disruption and data breach

    In February 2025, the French fintech firm Harvest suffered a major ransomware cyberattack, which completely paralysed its digital services, including its official website and customer access via VPN. According to the specialist magazine LeMagIT, the incident began with a targeted intrusion exploiting a vulnerability in the company’s cloud infrastructure, causing a total outage of its systems for several days. Many of the financial services offered by Harvest, including its investment and wealth management platforms, were severely affected.

    Cette cyberattaque a entraîné une fuite de données de clients et de salariés. Face à cette situation critique, Harvest a immédiatement mobilisé ses équipes techniques et fait appel à des experts externes pour contenir l’attaque et restaurer progressivement ses systèmes informatiques. Conformément à la réglementation européenne RGPD, les entreprises clientes ont dû rapidement notifier la CNIL afin de signaler cette violation de données.

  • NIS 2 Directive: an opportunity to strengthen resilience in the face of growing cyber threats

    NIS 2 Directive: an opportunity to strengthen resilience in the face of growing cyber threats

    The NIS 2 Directive, which aims to strengthen the cybersecurity of thousands of French public authorities and businesses, comes into force today. The draft bill for its transposition into national law has been presented to the Council of Ministers and will shortly be debated in Parliament. This directive broadens the scope of entities covered, now including around 15,000 organisations in France, and increases the requirements for securing information systems.

    Vincent Strubel, Director-General of ANSSI, has announced a three-year period for regulated entities to comply with the new obligations, whilst emphasising the importance of starting immediately. The obligations include carrying out risk assessments, reporting security incidents to ANSSI, strengthening the resilience of IT systems, and promoting a culture of cybersecurity within organisations. Significant financial penalties are envisaged in the event of non-compliance.

    Faced with the growing wave of cyber-attacks that potentially threaten the survival of businesses, the introduction of NIS 2 should be seen as an opportunity to strengthen their resilience. Solution providers and software vendors are ready to support organisations through this transition, offering services and technologies to improve their resilience. Thus, whilst 17 October may seem like a symbolic date, it marks the beginning of a new era of vigilance and proactivity in cybersecurity.
