They reduced visibility AFTER being caught taking.
Reducing transparency after being investigated. Consciousness of guilt. After a BTI advisory is published or an investigation becomes known, the vendor obfuscates code, removes documentation, blocks scanner user agents, or restructures endpoints to evade future detection.
How This Escalates BTI-C Findings
Escalates any prior BTI-C finding into an evasion pattern. If a vendor had C01 (Defeat Device) and then implements X13, the pattern demonstrates willful concealment rather than incidental behavior.
