TL;DR: GenAI is lowering the cost of impersonation across voice, video, chat and synthetic personas because those tactics are now cheaper, faster and more convincing, according to ActiveFence. Defenders need to verify identity and behaviour across interactions, not just screen out suspicious content.
Editorial analysis by NHI Mgmt Group, based on content published by ActiveFence: “How Scammers Are Abusing GenAI to Impersonate and Manipulate”.
Key questions
Q: Why do hijacked accounts make GenAI impersonation more damaging?
A: A hijacked account imports real reputation, audience history, and platform trust into the attack.
Q: How do security teams know if impersonation detection is actually working?
A: It is working if high-risk requests are consistently challenged, blocked, or escalated when the claimant cannot satisfy stronger proofing controls.
Q: What breaks when impersonation controls only look for fake content?
A: Content-only controls miss the identity layer of the abuse.
Practitioner guidance
- Red-team impersonation across channels Test voice, video, text, and synthetic persona abuse paths together, including how a model or workflow behaves when the same identity claim appears in multiple formats.
- Correlate account and content signals Link authentication events, account ownership changes, prompt activity, and posting behaviour so investigators can distinguish genuine identity continuity from manufactured legitimacy.
- Strengthen identity verification at interaction points Require higher assurance for account recovery, sensitive requests, and public-facing publishing where impersonation can create immediate fraud or reputation impact.
Bottom line: GenAI has reduced the cost of impersonation enough that identity abuse can now scale across voice, video, chat, and fake personas.

GenAI impersonation is now a trust-governance problem, not a content-moderation problem. The article shows that fake voices, videos, and personas can be chained with hijacked accounts to produce believable abuse across channels. That means identity assurance has to extend beyond login and into claims made during interaction, sharing, and account recovery. Practitioners should treat digital trust as a governed control surface, not a branding outcome.
A few things that frame the scale:
- 92% of organisations expose NHIs to third parties, raising concerns about supply chain security, according to the Ultimate Guide to NHIs.
- Generative AI use specifically increased from 33% in 2023 to 79% in 2025, according to McKinsey’s Global Surveys on the State of AI.
A question worth separating out:
Q: When should organisations escalate impersonation cases to fraud, IAM, or trust and safety teams?
A: Escalate when the abuse crosses identity boundaries, such as account takeover, recovery abuse, verified brand misuse, or repeated claims of authority that could trigger financial or operational harm. The right response is shared ownership, because impersonation is rarely just a content issue once an identity is being exploited to mislead users.
