In response to the risks,\nAnthropic has restricted access to Mythos and launched “Project\nGlasswing,” a cross-industry initiative to secure critical software. Mythos\nsignificantly outperforms previous models, uncovering serious long-standing\nflaws in widely used software.\n\nAs AI agents become fully autonomous cybersecurity actors, they accelerate\nboth offensive and defensive operations, systematically exploring attack paths\nand using sophisticated evasion techniques. This evolution also amplifies the\nquantum threat by enabling faster identification of cryptographic weaknesses\nand shortening the effective lifespan of classical encryption through\n“harvest now, decrypt later” strategies.\n\nIn this new environment, software-based security alone is no longer\nsufficient. SEALSQ emphasizes that the most effective long-term mitigation is\nthe integration of Post-Quantum Cryptography and other secure algorithms\ndirectly into silicon. By embedding PQC into secure microcontrollers and\nsemiconductor components, cryptographic operations are executed within\ntamper-resistant hardware environments, creating an immutable root of trust\nthat cannot be altered, bypassed, or extracted—even by AI-driven attacks.\n\nThis hardware-based approach fundamentally reduces the attack surface by\nmitigating vulnerabilities linked to software layers and misconfigurations. It\nensures that cryptographic keys are generated, stored, and used entirely\nwithin secure environments, protecting from unauthorized access or\nexfiltration. As a result, even highly autonomous AI agents would be unable to\nescalate privileges or compromise protected systems.\n\nWhile no system can claim absolute theoretical immunity, embedding PQC in\nsilicon raises the barrier to attack to a level that is practically\nunfeasible. Unlike software defenses, which can be continuously probed and\nexploited by AI, hardware-enforced cryptographic protections are inherently\nresistant to observation, manipulation, and iterative attack strategies.\nThe convergence of advanced AI and emerging quantum computing capabilities is\ncreating a new cybersecurity reality where hardware-rooted, quantum-resilient\ninfrastructures can provide sustainable protection. SEALSQ remains at the\nforefront of this transformation, developing next-generation semiconductors\ndesigned to secure digital ecosystems against both AI-driven cyber threats and\nfuture quantum attacks.\n\nAbout SEALSQ:\nSEALSQ is a leading innovator in Post-Quantum Technology hardware and software\nsolutions. Our technology seamlessly integrates Semiconductors, PKI (Public\nKey Infrastructure), and Provisioning Services, with a strategic emphasis on\ndeveloping state-of-the-art Quantum Resistant Cryptography and Semiconductors\ndesigned to address the urgent security challenges posed by quantum computing.\nAs quantum computers advance, traditional cryptographic methods like RSA and\nElliptic Curve Cryptography (ECC) are increasingly vulnerable.\n\nSEALSQ is pioneering the development of Post-Quantum Semiconductors that\nprovide robust, future-proof protection for sensitive data across a wide range\nof applications, including Multi-Factor Authentication tokens, Smart Energy,\nMedical and Healthcare Systems, Defense, IT Network Infrastructure,\nAutomotive, and Industrial Automation and Control Systems.
