After an LLM incident — a 48-hour GCC playbook spanning logs and notice.

At 7pm an analyst reported an internal assistant suggested text containing an account number surfaced through an unapproved prompt pattern. No named kill-switch owner sat on the runbook — forty minutes later the route paused; within eighteen hours it reopened under tightened policy and refreshed logs — not after a weekly strategy salon [1][2].

The forty-eight-hour playbook is minimum viable discipline for Nuqta whenever Gulf workloads touch personal or contractual data [5].

What counts as an LLM incident here.

Any processing breach that would not have occurred without the model route or its integrations — prompt exfiltration patterns, policy-breaking outputs, or broken access controls on a downstream tool [1][2].

Hours 0–8: contain, pause, timestamp.

  • Throttle or pause the affected route — reference prompt injection.
  • Preserve logs lawfully without over-collecting personal content.
  • Classify blast radius: prompt, indexed doc, or external tool via MCP boundaries.
  • Notify compliance per internal SLA — do not wait for a polished narrative.
Every hour after sensitive disclosure is a compliance decision — not a queued ticket.

Hours 8–24: impact assessment and conditional comms.

Determine whether personal data exited a documented path; if yes, follow internal then external notification cadence tied to PDPL impact and customer DPAs [4]. Do not fully reopen until output policy for that route is revalidated.

Hours 24–48: re-acceptance, not just "green status".

Restore traffic under reduced load with pre-launch acceptance metrics revived — pair hallucinated citations with RAG ops scorecard. Record root cause and vendor-facing lesson in one log both sides sign [2][5].

Closing.

After an LLM incident, trust returns via timestamps and owners — not press releases. A forty-eight-hour playbook prevents a breach becoming a month-long debate.

If kill-switch owner is unnamed today, you know where the runbook starts — before tomorrow.

Frequently asked questions.

  • Every incident external notice? Depends on data & contract — PDPL impact.
  • Shut down whole model? Rare — isolate route first.
  • Banking overlays? Add AML loops — GenAI AML Oman.
  • Private AI eliminate incidents? Reduces egress paths, not human mistakes.
  • Final authority? Compliance + IT sign-off [3].
