- •AI chat logs create detailed behavioral and psychological profiles richer than search engine logs, enabling exploitation for fraud, blackmail, identity theft, and targeted advertising—risks materialized in breaches like DeepSeek's January 2025 exposure of over one million chat logs with API keys[4].
