Money or Credentials Compromised? Use Free Official Channels First

1. Call Your Bank Fraud Desk & Police First

If funds, banking passcodes, or wire approvals were compromised, dial the official fraud number printed on the back of your bank card immediately to request a payment recall or account freeze, then report to local police.

2. Report Free to Official AU / US Agencies

In Australia, report free to ACCC Scamwatch (scamwatch.gov.au), IDCARE (idcare.org), and ReportCyber (cyber.gov.au). In the United States, report free to FBI IC3 (ic3.gov) and FTC ReportFraud (reportfraud.ftc.gov).

3. Never Pay "Fund Recovery" Services

Commercial privacy or security subscriptions are strictly preventative; paid tools never recover lost bank transfers or crypto, and agenticscam.com never recommends or links "recovery" agents.

Forensic Acoustic Studio for Synthetic Voice Clones, Video Deepfakes & Rogue Agents

Three seconds of public speech is enough to clone a relative or CFO voice, yet zero-shot neural vocoders and live voice-conversion streams leave measurable 8.0 kHz Nyquist shelves, dead-zero breath dropouts, and 740 ms buffer lag. Inspect live acoustic signatures on the studio bench below and build offline safe-word callback protocols before approving urgent requests.

HK$200 Million (US$25.6M) Arup Multi-Person Deepfake Video Call

CONFIRMED INCIDENT · HONG KONG POLICE (FEB 2024) & ARUP DISCLOSURE (MAY 2024)

In early 2024, a finance employee at UK engineering firm Arup's Hong Kong branch received a phishing email citing a confidential transaction. Skepticism vanished after the staffer joined an inbound multi-participant video conference populated by synthetic video and voice clones of the London CFO and multiple recognisable colleagues, resulting in 15 wire transfers totalling HK$200 million across five Hong Kong bank accounts before headquarters was contacted independently.

FCC Declaratory Ruling 24-17: AI Voices Illegal in Unconsented Robocalls

47 U.S.C. § 227 (TCPA) · CG DOCKET NO. 02-278 · ADOPTED 8 FEBRUARY 2024

The U.S. Federal Communications Commission unanimously ruled that AI-generated and cloned voices in outbound telephone calls constitute “artificial” voices under the Telephone Consumer Protection Act, empowering State Attorneys General and the FCC to prosecute callers and block originating voice gateways even when no funds are transferred.
