South Korean law enforcement is moving to arrest a prominent YouTuber accused of orchestrating a malicious defamation campaign against actor Kim Soo-hyun. Investigators allege that the content creator utilized advanced artificial intelligence to manufacture false evidence, including deepfake audio and doctored text messages, designed to implicate the actor in an inappropriate relationship with the late actress Kim Sae-ron. These fabricated claims, which surfaced following the actress’s death, caused significant damage to the actor’s reputation and led to widespread public backlash.

According to police findings, the YouTuber allegedly used AI to synthesize the actress’s voice, creating a recording that falsely suggested a relationship dating back to her middle school years. Furthermore, investigators claim that private communications were digitally altered to serve as evidence of an affair. These actions, reportedly motivated by financial gain, have had severe professional consequences for Kim Soo-hyun, including the indefinite suspension of his upcoming projects, such as the Disney+ series ‘Knock-Off’.

Kim Soo-hyun has vehemently denied the allegations, clarifying that any association with the actress occurred only after she reached the age of majority. In March 2025, the actor held a press conference to refute the claims and initiated criminal proceedings against the YouTuber and the actress’s family for the dissemination of false information. The intense scrutiny and professional fallout have reportedly taken a toll on the actor’s mental health, leading him to seek professional psychiatric support.

While the YouTuber has characterized the police investigation as a retaliatory effort against his content, authorities are continuing their pursuit of an arrest warrant. The case has sparked a national conversation regarding the vulnerability of public figures to AI-generated disinformation and the urgent need for stricter accountability for digital content creators who exploit emerging technologies to destroy reputations.

By leveraging synthetic media to manufacture ‘evidence,’ bad actors can now inflict irreparable damage on a public figure’s reputation with unprecedented speed and perceived authenticity.
