TL;DR: GenAI is making impersonation scams cheaper, faster, and more convincing across voice, video, chat, and synthetic personas, according to ActiveFence, which argues that platforms need proactive red teaming, adaptive guardrails, stronger verification, and abuse visibility to keep pace. The core risk is not just fake content, but trust erosion at account, interaction, and lifecycle boundaries where identity controls can still fail.
NHIMG editorial — based on content published by ActiveFence: How Scammers Are Abusing GenAI to Impersonate and Manipulate
By the numbers:
- 72% of organisations have experienced or suspect they have experienced a breach of non-human identities, with 46% confirmed and 26% suspected.
Questions worth separating out
Q: How should security teams defend against AI-powered impersonation attacks?
A: Security teams should combine strong identity verification with continuous monitoring and tight authorization limits.
Q: Why do hijacked accounts make impersonation scams more dangerous?
A: Hijacked accounts already carry audience trust, so attackers do not need to build credibility from scratch.
Q: What do organisations get wrong about deepfake detection training?
A: They assume people can be trained to spot synthetic media reliably enough to stop fraud.
Practitioner guidance
- Red team for impersonation abuse across all media types Test how your platform behaves when attackers use cloned voices, deepfake video, synthetic personas, and multilingual scam scripts.
- Add session-level abuse visibility to verification controls Track when, where, and how impersonation attempts occur, not just whether the content was blocked.
- Treat hijacked accounts as trust revalidation events When an account is taken over, require a fresh trust decision before it can publish, message, or transact again.

Impersonation is now an identity governance problem, not just a content moderation problem. The article shows that synthetic media succeeds when platforms cannot reliably validate who, or what, is speaking. That shifts the issue from moderation queues to verification, provenance, and trust lifecycle control. For identity programmes, the lesson is that fraud prevention and IAM now overlap at the point where an account, persona, or session is believed to be real.
A question worth separating out:
Q: How can platforms verify identity without creating too much friction?
A: Use risk-based verification so low-risk interactions stay simple while high-risk actions trigger stronger checks. Re-verify when the source, timing, or content changes materially, and reserve stronger steps for payments, official notices, account recovery, or public-facing statements. That keeps friction targeted and improves protection where abuse would hurt most.
