How This Briefing Works
This report opens with key findings, then maps the gaps between what Slides Google discloses and what BLACKOUT observed at runtime. From there: what it means for your organization, what to do about it, and the detection data and evidence underneath.
Key Findings
Pre-Consent Activity
Slides Google was observed loading and executing before user consent was obtained on 48% of sites where it was detected.
Claims vs. Observed Behavior
disclosure
“Pending claims extraction”
Runtime detection shows C06 (behavioral biometrics), C08 (cross-domain sync), and C09 (consent bypass)
What This Means For You
What To Do About It
Role-specific actions based on observed behavior
If You Use Slides Google
- →Audit all embedded Google Slides for consent-gated initialization
- →Implement iframe sandboxing to prevent cross-domain sync until consent obtained
- →Review Google Workspace DPA for embedded content data handling
If You're Evaluating Slides Google
- →Document pre-consent tracking activation in Slides embeds
- →Request technical specification for disabling cross-domain sync in embedded contexts
- →Obtain written confirmation of data deletion procedures for behavioral fingerprints
Negotiation Leverage
- →Pre-consent tracking: Embedded Slides iframes activate Google analytics before consent — require technical controls to defer initialization.
- →Cross-domain sync: Slides coordinate with google.com to link user identity — negotiate opt-out from identity graph participation for embedded contexts.
- →Behavioral data retention: Interaction patterns persist in Google ecosystem — demand specific deletion timelines and verification procedures.
Runtime Detections
BLACKOUT observed this vendor's JavaScript executing in a live browser and classified each hostile behavior using our BTI-C (Behavioral Threat Intelligence — Capability) taxonomy. These are not theoretical risks — each code below was triggered by something we watched this vendor's code actually do.
Keystroke/mouse tracking
Identity stitching
Ignoring CMP signals
IOC Manifest
Indicators of compromise across 3 categories. Use for detection rules, CSP policies, or Pi-hole blocklists.
