The era of cybersecurity equilibrium is over. For twenty years, the cybersecurity landscape has not changed dramatically it has evolved however the landscape remained relatively predictable, but we have reached a tipping point. As highlighted by Anthropic’s recent disclosures, the economics of exploitation are shifting. The cost to find and weaponising critical flaws is collapsing, and the window for defence is shrinking.
There are the usual questions about how capable Mythos is and how much is Anthropic selling their capability. I suspect the answer is somewhere in the middle however the key takeaway is that defenders need to improve current approaches.
To survive this shift, defenders must move from observation to integration immediately.
1. Build the Scaffolding Now
You do not need to wait for “Mythos Preview” to begin. Current frontier models, such as Opus 4.6, are already identifying high and critical-severity vulnerabilities in open-source projects.
- The Goal: Build the infrastructure and workflows today.
- The Edge: When more powerful models arrive, teams with established AI pipelines will be ready to scale, while others will be overwhelmed.
2. Automate Security Toil
The volume of security work is about to increase exponentially. Human-only teams will be the primary bottleneck. Models should be immediately deployed to assist with:
- Alert Triage: Filtering noise to highlight genuine threats.
- Patch Prioritisation: Determining what needs fixing first.
- Documentation: Using LLMs to automate incident response logs and PR reviews.
3. Rethink the Economics
We are not witnessing “AI magic,” but rather a fundamental change in the cost of aggression. As the barrier to entry for sophisticated attacks falls, the onus on defenders to automate and respond rises.
What should you be doing:
- Experiment: Run current models against your own codebases to identify existing gaps.
- Refresh Policies: Ensure your disclosure and response policies can handle a higher velocity of findings.
- Monitor: Follow Project Glasswing closely; the tools of the trade are evolving so don’t be left behind.
