In response to the risks, Anthropic has restricted access to Mythos and launched \u201cProject Glasswing,\u201d a cross-industry initiative to secure critical software. Mythos significantly outperforms previous models, uncovering serious long-standing flaws in widely used software.<\/p>\n<p>As AI agents become fully autonomous cybersecurity actors, they accelerate both offensive and defensive operations, systematically exploring attack paths and using sophisticated evasion techniques. This evolution also amplifies the quantum threat by enabling faster identification of cryptographic weaknesses and shortening the effective lifespan of classical encryption through \u201charvest now, decrypt later\u201d strategies.<\/p>\n<p align=\"justify\">In this new environment, software-based security alone is no longer sufficient. SEALSQ\u00a0emphasizes that the most effective long-term mitigation is the integration of Post-Quantum Cryptography and other secure algorithms directly into silicon. By embedding PQC into secure microcontrollers and semiconductor components, cryptographic operations are executed within tamper-resistant hardware environments, creating an immutable root of trust that cannot be altered, bypassed, or extracted\u2014even by AI-driven attacks.<\/p>\n<p align=\"justify\">This hardware-based approach fundamentally reduces the attack surface by mitigating vulnerabilities linked to software layers and misconfigurations. It ensures that cryptographic keys are generated, stored, and used entirely within secure environments, protecting from unauthorized access or exfiltration. As a result, even highly autonomous AI agents would be unable to escalate privileges or compromise protected systems.<\/p>\n<p align=\"justify\">While no system can claim absolute theoretical immunity, embedding PQC in silicon raises the barrier to attack to a level that is practically unfeasible. Unlike software defenses, which can be continuously probed and exploited by AI, hardware-enforced cryptographic protections are inherently resistant to observation, manipulation, and iterative attack strategies.<br \/>The convergence of advanced AI and emerging quantum computing capabilities is creating a new cybersecurity reality where hardware-rooted, quantum-resilient infrastructures can provide sustainable protection. SEALSQ\u00a0remains at the forefront of this transformation, developing next-generation semiconductors designed to secure digital ecosystems against both AI-driven cyber threats and future quantum attacks.<\/p>\n<p align=\"justify\">\n        <b>About SEALSQ:<\/b><br \/>\n        <br \/>SEALSQ is a leading innovator in Post-Quantum Technology hardware and software solutions.
