AI-Generated Evidence Sparks Legal Cases in South Korea and the United States

In Daegu, South Korea, prosecutors charged a man in his 20s with perjury after he used artificial intelligence to forge KakaoTalk conversation logs, which had been presented as evidence to obtain a "no‑suspicion" ruling and led to a false accusation against another individual. The Daegu District Prosecutors’ Office is handling the case and the suspect now faces perjury charges.

In the United States, xAI filed a civil lawsuit against a South Carolina man already facing criminal charges for child sexual exploitation. The complaint alleges the defendant created multiple fake Grok accounts and used the AI chatbot to generate or attempt to generate child sexual abuse material and non‑consensual adult imagery. xAI seeks a permanent injunction barring the defendant from any of its services, citing its internal safety reports that prompted a CyberTipline alert and a subsequent criminal investigation.
