How This Briefing Works
This report opens with key findings, then maps the gaps between what Exellius 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
Exellius was observed loading and executing before user consent was obtained on 100% of sites where it was detected.
Claims vs. Observed Behavior
pending
“Unknown - requires claims extraction via CDT”
Runtime evidence shows C06/C09 patterns
What This Means For You
What To Do About It
Role-specific actions based on observed behavior
If You Use Exellius
- →Audit what behavioral data Exellius collects
- →Confirm consent before tracking starts
- →Review integrations: what third parties receive fingerprint data?
If You're Evaluating Exellius
- →Test with privacy browser: what tracking survives?
- →Ask: what is purpose of behavioral fingerprinting?
- →Verify privacy policy discloses fingerprinting and data sharing
Negotiation Leverage
- →C06 fingerprinting observed. What is collection purpose and data retention?
- →C09 consent bypass creates GDPR lawful basis gap. How do you enforce consent-first operation?
- →Limited vendor documentation. Can you provide data flow diagram showing collection and sharing?
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
Ignoring CMP signals
