Fact Check
Multiple credible and relevant news sources directly report that a leak from South Korea's National Tax Service exposed sensitive information, specifically a mnemonic phrase, which enabled the theft of seized virtual assets valued at approximately $4.8 million in PRTG tokens. The MK news report is highly authoritative and directly confirms the link between the agency's promotional event and the asset theft. Another independent report from MEXC corroborates the details, framing it as a significant institutional security lapse. A third source with slightly lower authority also consistently repeats this narrative. These accounts are mutually reinforcing and describe the same chain of events: the leak stems from a government entity, the stolen assets are PRTG tokens, and the valuation matches $4.8 million. There are no credible sources that contradict the statement, and tangential or unrelated materials do not undermine it. Given the alignment of independent, authoritative sources and the specificity of details, the statement is highly likely to be true.
