TL;DR: Claude Mythos Preview identified thousands of zero-day vulnerabilities across major operating systems and browsers, including a 27-year-old OpenBSD bug that had evaded detection since 1997, underscoring how AI-driven discovery compresses defender response time, according to Silverfort. The security problem has shifted from patching faster to reducing blast radius and governing non-human identities before AI-speed attackers chain exposure into access.
NHIMG editorial — based on content published by Silverfort: Claude Mythos and the new reality of AI-speed vulnerability discovery
Questions worth separating out
A: They should shift from point-in-time vulnerability handling to continuous exposure reduction.
Q: Why do non-human identities become a bigger risk in AI-speed attacks?
A: Because NHIs often provide the shortest route from discovery to real access.
Q: What is the difference between vulnerability scanning and continuous exposure management?
A: Vulnerability scanning tells you what exists.
Practitioner guidance
- Run an AI-assisted attack surface assessment Model what an AI attacker would discover first in your environment, then rank the reachable paths by privilege and blast radius.
- Inventory and classify every non-human identity Document service accounts, API keys, OAuth tokens, certificates, and bot identities, then assign an owner, a purpose, and a renewal or rotation cadence for each one.
- Prioritize continuous exposure scoring over periodic scanning Tie vulnerability data to authentication paths and over-privileged access so remediation targets the issues an attacker can chain now, not just the ones with the highest CVSS score.
With 85% of organisations lacking full visibility into third-party vendors connected via OAuth apps, per The State of Non-Human Identity Security, the governance gap is already wide before AI gets involved?

AI-speed discovery turns vulnerability management into identity risk management. Once an attacker can identify weaknesses in hours or weeks rather than months, the relevant question is not just whether a system is patchable. It is whether the surrounding identity estate can limit what follows discovery. For NHI governance, this means privilege, ownership, and authentication monitoring become part of the vulnerability workflow, not a separate control layer. Practitioners should treat fast discovery as an identity blast-radius problem.
A few things that frame the scale:
- 1 in 4 organisations are already investing in dedicated NHI security capabilities, with an additional 60% planning to do so within the next twelve months, according to The State of Non-Human Identity Security.
- Only 1.5 out of 10 organisations are highly confident in their ability to secure NHIs, compared with nearly 1 in 4 for securing human identities.
A question worth separating out:
Q: Should organisations invest in AI offensive testing before adversaries do?
A: Yes, if it is paired with clear governance and remediation. Defensive AI testing helps teams see how an attacker would reason through code, infrastructure, and identity paths, but the value comes from turning those findings into least privilege, tighter token lifetimes, and better monitoring. Otherwise it becomes an exercise in awareness without risk reduction.
