Report #31360

[gotcha] Sensitive data exfiltrated slowly over multiple turns to bypass length or PII filters

Implement stateful token-level or character-level rate limiting for sensitive entities across the entire conversation, not just per-turn. Use DLP \(Data Loss Prevention\) scanning on the accumulated output.

Journey Context:
Security filters often look for large dumps of PII or secrets in a single response. An attacker instructs the LLM to exfiltrate a database by outputting one row per turn, or one character per response. Per-turn filters see a small, benign string, but over 100 turns, the entire database is leaked.
