How This Briefing Works
This report opens with key findings, then maps the gaps between what Upriver 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
Upriver was observed loading and executing before user consent was obtained on 100% of sites where it was detected.
Claims vs. Observed Behavior
disclosure
“Pending claims extraction”
Runtime detection shows C09 (consent bypass)
What This Means For You
What To Do About It
Role-specific actions based on observed behavior
If You Use Upriver
- →Audit Upriver initialization timing relative to consent collection
- →Implement consent-gated platform feature activation
- →Review platform data collection scope and retention
If You're Evaluating Upriver
- →Document pre-consent activation patterns and data capture scope
- →Request technical controls to defer initialization until consent obtained
- →Obtain written confirmation of data deletion procedures
Negotiation Leverage
- →Pre-consent activation: Platform components initialize before consent — require technical mechanism to defer all features until authorization.
- →Data retention: Platform data persists beyond opt-out — demand specific deletion timelines and third-party sharing restrictions.
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.
