Move from reading to investigating SMBGhost Exploitation. The workspace is a structured analysis surface — not a chat — organised as:

  1. Question — what do you need to know about SMBGhost Exploitation?
  2. Evidence — assertions mapped to verifiable references.
  3. Timeline — events in chronological order.
  4. Related Entities — CVE, threat actor, campaign, malware links.
  5. Sources — NVD, CISA KEV, MITRE ATT&CK, vendor advisories.
  6. Notes — your own observations and working hypotheses.

AI assistance is limited to summarising, explaining, and suggesting related evidence. AI never completes your investigation, modifies entity relationships, or generates facts — all published analysis stays human-reviewed.
