SCWorld.com reported that “Anthropic’s Claude Mythos Preview has landed with the kind of reception security leaders can’t dismiss. Anthropic says the model has already identified thousands of high-severity vulnerabilities, including in major operating systems and web browsers, and has limited access to it through Project Glasswing rather than making it broadly available.” The April 16, 2026 article entitled “6 steps to harden security programs for the Claude Mythos surge” (https://tinyurl.com/3fur36t5) included these 6 steps:
#1 Treat AI exposure as an attack surface.
#2 Re-rank identity controls before phishing gets better again.
#3 Shorten the window between exposure and mitigation.
#4 Put guardrails around AI-assisted development.
#5 Run exercises that assume the attacker also has automation.
#6 Push third parties harder on assurance.
