OAuth grant sprawl creates persistent SaaS access risk (Klue breach example)
- Engineer — Plan: OAuth grant sprawl is a real exposure in any cloud/SaaS estate; this quarter, audit all third-party OAuth grants in your IdP and SaaS apps, revoke stale ones, and implement a review gate for new grant requests.
- SOC/IR — Learn: The Klue breach illustrates how dormant OAuth grants become persistent access paths, but no IOCs or ATT&CK-mapped TTPs are provided here — useful framing for future detection design around anomalous OAuth token usage, not actionable today.
- Leader — Plan: The Klue breach case makes this board-adjacent: establish an OAuth grant inventory and periodic review policy for your SaaS estate before an unreviewed grant becomes your own incident.
