Using an unordered list, summarize the following article with between 4 and 8 key points. Cybersecurity implications of frontier AII am writing to draw your attention to the cybersecurity implications of recent advances in frontier AI, and set out what we need to do in response.In the past month, frontier AI has materially shifted the cybersecurity baseline for CIIs. On 7 April 2026, Anthropic announced Claude Mythos Preview, but restricted access to vetted defenders under Project Glasswing because of its advanced cyber capabilities. Anthropic stated that Mythos had already identified thousands of zero-day vulnerabilities. Shortly after, the UK AI Security Institute reported that Mythos could execute multi-stage attacks on vulnerable networks and had become the first model it tested to complete a 32-step end-to-end corporate network intrusion simulation, estimated to take an expert human around 20 hours. OpenAI\u2019s subsequent release of GPT-5.5 reinforces the same direction of travel: OpenAI assesses the model as having \u201cHigh\u201d cybersecurity capability under its Preparedness Framework, one step below \u201cCritical\u201d.These developments demand board-level and CEO attention, especially for CII owners and should not be left to IT departments. Frontier AI is accelerating at a rate where current assumptions in cyber risk management, on which your controls, measures and incident response plans were designed, may no longer be valid.\u00a0Vulnerability discovery is becoming faster and cheaper. Social engineering is becoming more convincing and more personalised. Multi-stage attack chains can increasingly run without human intervention. Suppliers and interconnected systems face similarly heightened pressure. The window between vulnerability disclosure to system owners and exploitation by bad actors is narrowing, and the level of\u00a0expertise\u00a0required\u00a0to mount a competent attack is falling.To help CII Owners navigate the changed risk environment, CSA\u2019s alert (NCSC\/Alert\/2026\/066) on 13 April 2026 has set out the immediate technical mitigations to be followed up on. Beyond this, we ask that Boards commission a review of whether your cybersecurity risk posture remains adequate in light of frontier AI development.This review should consider:1.\u00a0\u00a0\u00a0\u00a0 whether the organisation\u2019s current cyber risk assessment takes relevant account of AI-enabled threats, both for IT and OT systems;\u00a02.\u00a0\u00a0\u00a0\u00a0 whether visibility over critical systems, internet-facing assets, privileged access, cloud\u00a0services\u00a0and third-party dependencies\u00a0remains\u00a0sufficient;\u00a03.\u00a0\u00a0\u00a0\u00a0 whether vulnerability management, patching,\u00a0monitoring\u00a0and incident response arrangements are fast enough as\u00a0adversary\u00a0tempo accelerates;4.\u00a0\u00a0\u00a0\u00a0 whether your organisation\u2019s\u00a0own use of AI is appropriately governed,\u00a0particularly where AI tools interact with sensitive data, software development,\u00a0cybersecurity\u00a0operations\u00a0or critical systems; and5.\u00a0\u00a0\u00a0\u00a0 where AI can be used to augment current cybersecurity operations, including review of your organisation\u2019s code security.This review\u00a0should be tabled at the appropriate\u00a0Board or executive\u00a0governance risk committee. Where material gaps are\u00a0identified, management should ensure that these are addressed through\u00a0clear remediation plans and explicit risk\u00a0acceptance decisions\u00a0and where necessary, adjustments to cybersecurity investment priorities.\u00a0CSA will engage your respective sector lead in the coming weeks to take stock of progress, understand challenges faced and discuss where we can work together to further strengthen your cybersecurity posture.On our part, CSA will continue to\u00a0monitor\u00a0these developments, publish further technical guidance as the picture evolves,\u00a0and work with our partners across industry and government to\u00a0strengthen Singapore\u2019s collective cyber resilience.\u00a0Thank you for your continued partnership in safeguarding Singapore\u2019s essential services.Yours sincerely,David KohCommissioner of Cybersecurity
