FL – 001 | Deepfake Voice Clone Audit

LOG ID: FL-001
CLASSIFICATION: North American Digital Shield
SECURITY STATUS: Active Compromise / Public Awareness
SUBJECT UNDER AUDIT: Generative AI Voice Cloning / Synthetic Media
PRIMARY AUDITOR: Paul Mindra (AI Integrity Auditor)

Purpose

Confirm whether an audio message is a high‑fidelity voice clone and collect defensible artifacts.

Immediate actions

• Do not act on requests for money, credentials, or access.
• Preserve the audio file and any associated messages; note timestamps.

Step‑by‑step checks

• Capture original file: save the audio with metadata and call logs.
• Request secondary verification: ask for a live video call or in‑person confirmation.
• Compare authenticated samples: match cadence, prosody, and idiosyncratic speech patterns.
• Run acoustic analysis: inspect spectrograms, unnatural pauses, and synthesis artifacts.
• Trace telephony headers: collect SIP/VoIP headers, caller ID routing, and any linked domains.
• Search for reuse: reverse search phrases or short clips to find other appearances.

Evidence to collect

• Original audio file; call logs; authenticated voice samples; SIP/telephony headers; screenshots; timestamps; file hashes.

High‑confidence red flags

• Near‑perfect mimicry with odd phrasing; caller ID mismatches; spectral artifacts consistent with synthesis.

Action thresholds

• High risk: freeze transactions, notify security/legal, preserve chain of custody.
• Medium risk: require independent confirmation before action.
• Low risk: document and monitor.

Phone script

“Hold on — I’ll confirm this on a video call and call you back on the number I already have.”
