OpenAI Astra Model Paused Over Cyber Capability Gains: What Defenders Must Do Now

title: High-Velocity Interactive Shell Command Sequence
tid: b4e1a2c3-9f05-4d6e-8a7b-2c3d4e5f6a7b
status: experimental
description: Detects abnormally dense sequences of child processes spawned by a shell or scripting interpreter in a short window, consistent with agentic/automated attack tooling iterating at machine speed rather than human operator tempo.
