South Korean police are investigating multiple cases of "crypto-funded retaliation attacks" where suspects were paid in cryptocurrency to commit acts of vandalism and harassment. The suspects reportedly received payments ranging from $300 to $600 in cryptocurrency for tasks such as graffiti, dumping food waste, spraying feces at victims' homes, and distributing defamatory leaflets. Many of the suspects claimed they were unaware of the identities of those who hired them, with assignments often coordinated via Telegram.
