Returned crypto stolen again from Korean authorities

After a thief drained a crypto wallet of 4 million PRTG (notionally priced at $4.9 million, but highly illiquid) after blundering Korean tax officials posted the wallet's seed phrase to social media in a photo among other seized items, the thief returned the assets. However, the tokens were quickly stolen again by a second thief, as they'd been returned to the same vulnerable wallet. The first thief turned themselves in and was arrested by Korean law enforcement shortly after taking the funds; the second thief has not been identified.
