Detection relies on multi‑modal analysis of video, audio, and behavior, plus computer vision and audio processing, but remains limited by an ongoing arms race with generation methods.

Deepfakes have evolved from misinformation tools into sophisticated cyber weapons that threaten digital trust and biometric authentication systems.

Supply chain impersonations leverage vendor negotiations, supported by fake documents and signatures to sway decisions.

Deepfake capabilities now span realistic video, synthetic voices, and emotion replication, enabling CEO fraud, credential theft, business email compromise, and supply chain impersonation.

Defenses require a layered approach that blends technology, processes, and human judgment, emphasizing adaptable, user‑friendly authentication systems.

Legal and regulatory considerations include compliance, liability, insurance gaps, and the challenges of cross‑border cooperation in incidents.

Adversarial training and real‑time adaptation by deepfake generators undermine static detection, making continual updating essential.

BEC attacks now blend phishing with real‑time synthetic audio to boost credibility and success rates.

Biometric systems relying on facial and voice data remain vulnerable to deepfakes, as liveness checks and verification can be bypassed by realistic media.

Enterprise defenses should include multi‑factor biometric verification, hardware and device signals, centralized identity management, and human verification for high‑risk actions.

CEO fraud frequently uses synthetic video calls to pressure urgent transfers, with losses ranging from hundreds of thousands to millions across multiple incidents.

Incident response should follow standard guidelines: immediate containment, preserve evidence, conduct forensic analysis, communicate with stakeholders, and consider regulatory implications.
