doppelganger_impersonation
Doppelganger impersonation involves creating fake websites, social media accounts, or media outlets that closely mimic legitimate, trusted sources in appearance, name, and design. The goal is to publish disinformation under the borrowed credibility of the impersonated source. Audiences who encounter the content may not notice subtle differences in domain names or branding and accept the false content as legitimate journalism or official communication.
A disinformation operation creates a website at 'bbc-news.com.de' that perfectly replicates the BBC's visual design, logo, and layout. The site publishes articles mixing real BBC content with fabricated stories about European refugee crises. Shared on social media, the articles appear to carry the BBC's authority. Similar operations have impersonated Der Spiegel, Le Monde, and The Washington Post.
A fake Twitter account named '@WHO_Health' — using the World Health Organization's logo and a near-identical handle to the real '@WHO' account — begins posting fabricated health advisories during a disease outbreak, telling followers that a specific over-the-counter drug is 'officially recommended.' Thousands retweet the false guidance before the real WHO issues a warning about the impersonator.
A disinformation campaign registers the domain 'reuters-news.net,' replicates Reuters' full website design, and publishes a fabricated 'exclusive report' claiming a foreign government has secretly surrendered in an ongoing conflict. The fake article is shared widely on social media, with many users not noticing the URL difference, and the story briefly moves currency markets before Reuters publicly debunks it.

People use visual cues and brand recognition as shortcuts for credibility assessment. When a website looks like a trusted source, the content inherits that trust. Most users do not scrutinize URLs or verify that a social media account is the official one, especially when content is encountered via shared links in feeds.
Always verify the exact URL of any news source. Check for official verification marks on social media accounts. Cross-reference stories with the actual legitimate source's website. Be especially suspicious of explosive or inflammatory stories from sources you normally trust — verify they actually published it.
Extensively used in Russian influence operations targeting European audiences (the 'Doppelganger' campaign identified by EU DisinfoLab). Also used in phishing attacks, financial fraud, and corporate sabotage. The technique has been documented impersonating dozens of major European and American media outlets.
