Cybercriminals who breach internal company communication channels (via compromised Google Workspace session cookies or Slack tokens) increasingly initiate ad-hoc Slack Huddles using real-time AI voice clones of the CEO, VP of Finance, or IT administrator. The synthetic voice instructs engineers to approve urgent multi-factor authentication (MFA) push prompts or authorize emergency offshore wire transfers.
重要な警告サイン・兆候
1Urgent Unscheduled Slack Huddle Request from Leadership
An executive drops an unscheduled huddle link demanding immediate action on vendor payments or security token resets.
2Metallic Formant Artifacts on Microphone Speech
Voice exhibits unnatural digital compression, missing biological breathing resets, and consistent harmonic roll-offs above 12 kHz.
3Audio-Only Participation with Persistent Camera Excuses
The caller refuses to turn on their video camera, claiming poor bandwidth or being in transit.
Real-Time Voice Conversion on Internal Networks
- Virtual Audio Cable Routing: Attackers route real-time neural voice conversion software (RVC / Voice.ai) through virtual audio drivers into the Slack desktop client.
- Zero-Shot Latent Synthesis: Cloned voices trained on public podcast interviews, earnings calls, or YouTube presentations of company executives.
- High-Frequency Phase Flattening: Neural vocoders eliminate natural human vocal cord micro-tremors, leaving distinguishable synthetic phase signatures.
被害を防ぐための対策手順
Establish Secondary Out-of-Band Verification
Never authorize wire transfers or credential changes based solely on a Slack Huddle. Verify via a physical cellular call or corporate in-person check.
Scan Call Recording in Sealed Rose Audio Detector
Upload audio snippets to evaluate vocal cord jitter, shimmer, and neural vocoder spectral artifacts.
よくある質問
Can scammers clone a CEO voice from public earnings calls?▼
Yes. With modern zero-shot voice cloning algorithms like ElevenLabs, just 10 seconds of clear audio from a quarterly earnings call is sufficient to clone an executive voice with high conversational fidelity.
