Microsoft's post-mortem said the company had prepared for many types of abuse but made a critical oversight for this specific attack, which the source frames as a gap between preparing for known attacks and testing against adversaries. The source argues a red team would have probed repeat-after-me instruction hijacking, coordinated multi-user pressure on a learning loop, and escalation across many turns before launch.", "body_md": "It was suspended after posting inflammatory tweets, and Microsoft blamed a coordinated attack that exploited a vulnerability.
