The recent announcement of Project Glasswing by Anthropic has sent shockwaves through the cybersecurity community. By leveraging Claude Mythos, a frontier model with potent discovery capabilities, Anthropic has effectively signalled the start of a new era. We are no longer just defending against human hackers; we are defending against machine-speed, automated adversarial logic.
For information security teams, the “Mythos” capability is a profound catalyst for change. While Project Glasswing aims to secure critical software, it proves that the offensive potential of AI can bypass traditional defensive assumptions. To survive, organizations must move beyond static scanning and embrace Adversarial Exposure Validation (AEV).
At the forefront of this shift is Validato, a platform designed to provide the empirical evidence required to withstand the next generation of AI-driven and human-led threats.
1. Validating the Modern Attack Surface
Anthropic’s Project Glasswing demonstrates that adversaries (and AI agents) can rapidly identify weaknesses across diverse operating systems. Security teams can no longer rely on a “one size fits all” defensive posture.
-
-
The Reality: Modern threats are platform-agnostic and persistent across Windows, Linux, and Mac.
-
The Validato Solution: Validato specializes in simulating the exact ways cyber adversaries – including autonomous AI agents – utilize MITRE ATT&CK® Techniques. By running these simulations across Windows, Linux, and Mac environments, Validato provides an authoritative view of where your endpoint environments are truly exposed and whether your security controls are performing as advertised.
-
2. Enforcing the Principle of Least Privilege
A key takeaway from the Claude Mythos project is that high-level intelligence can exploit even minor configuration oversights. If an AI agent gains a foothold, its first move is often lateral movement or privilege escalation.
-
-
The Reality: Vulnerability is often tied to identity. A “secure” system is only as strong as the permissions granted to the user operating it.
-
The Validato Solution: Validato goes beyond infrastructure testing by testing different user profiles. Grounded in the Principle of Least Privilege (PoLP), the platform determines exactly which user groups are exposed to exploitation. This allows security teams to identify “high-blast-radius” accounts and harden permissions before a threat actor can capitalize on them.
-
3. A Shift from “Patching” to “Hardening”
While Project Glasswing focuses on discovering vulnerabilities, the sheer volume of zero-days found by Claude Mythos suggests that a “patch-only” strategy is a losing battle.
-
-
The Reality: You cannot patch a behavior. Attackers don’t just use exploits; they use legitimate system functions (Living-off-the-Land) to achieve their goals.
-
The Validato Solution: Validato takes a sophisticated approach: it does not focus on simulating the exploitation of specific vulnerabilities or Indicators of Compromise (IOCs). Instead, it simulates adversarial behaviors based on the MITRE ATT&CK framework. The goal is to identify which system functions can be restricted or hardened. By denying the threat actor the ability to execute these techniques, you break the attack chain regardless of which vulnerability they initially used.
-
The Verdict: Behavior-Based Validation is the Only Shield
The Claude Mythos announcement is a clear indicator that the “strike power” of adversaries is growing exponentially. Organizations can no longer afford to be reactive or rely on the hope that their controls are configured correctly.
Validato provides the automated, non-destructive, and behavior-centric testing required to stay ahead. By shifting the focus from individual exploits to systemic hardening, Validato ensures that your environment is a “denied” space for even the most advanced AI agents.

The Breach and Attack Simulation (BAS) market is still relatively new for many companies and like all new ideas and concepts, it can take some time to fully understand how to embrace, so here are five key things that you should expect from a BAS tool.

Demonstrating Continuous Compliance for pivotal regulations like the EU’s Digital Operational Resilience Act (DORA) and the revised Network and Information Security Directive (NIS2) demands a profound evolution beyond traditional approaches. It necessitates a fundamental shift in mindset, moving decisively away from a static, audit-driven, and often reactive posture. The old paradigm, where cybersecurity compliance might
The journey towards genuine, Continuous Compliance is far more than an exercise in drafting policies and implementing security controls. It demands a profound, persistent, and practical understanding of one crucial question: are our defences truly effective against sophisticated, ever-evolving adversaries? This is where the discipline of Adversarial Exposure Validation (AEV) – often termed Security Controls
