How This Briefing Works
This report opens with key findings, then maps the gaps between what Justcall 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
Justcall was observed loading and executing before user consent was obtained on 100% of sites where it was detected.
Claims vs. Observed Behavior
consent_timing
“Unknown - requires claims extraction”
C09 consent bypass observed in runtime behavior
What This Means For You
What To Do About It
Role-specific actions based on observed behavior
If You Use Justcall
- →Implement consent gate before Justcall initialization
- →Verify call tracking functionality with post-consent loading
- →Maintain consent timestamp records vs Justcall execution timing
If You're Evaluating Justcall
- →Request Justcall consent integration technical documentation
- →Evaluate revenue intelligence platforms with consent-first architecture
- →Consider server-side call tracking to avoid browser consent requirements
Negotiation Leverage
- →Justcall deploys pre-consent - require consent-aware initialization capabilities
- →Demand technical documentation of consent management integration
- →Negotiate consent bridge implementation as contract term
- →Establish liability allocation for pre-consent data collection violations
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.
