South Koreans Used Crypto to Fund 'Human Waste' Revenge Attacks, Police Report Reveals - Crypto Economy

TL;DR

• South Korean police arrested two operatives in a crypto-paid harassment-for-hire crime network.
• The scheme exploited cryptocurrency’s anonymity to keep clients hidden from arrested operatives.
• Recent South Korean cases link cryptocurrency anonymity features with violent crimes.

South Korean police broke up part of an organization that sold harassment services in exchange for cryptocurrency. Clients placed orders through Telegram, transferred digital currency as payment, and received targeted attacks against specific individuals in return: printed threats, damaged property, and in several cases, human waste dumped in front of private residences.

Two of the operatives, identified in local press as “Mr. Lim” and “Mr. K,” face charges for vandalizing residential doors and distributing leaflets carrying direct intimidation messages. At least part of the printed material bore the phrase “I will not leave you alone.” Both men were arrested within the past week, though authorities acknowledge their superiors within the network remain unidentified.

Payment per job ranged between 500,000 and 1,000,000 South Korean won — the equivalent of roughly $337 to $675 — settled in cryptocurrency. Suspects questioned across at least three cases, with incidents dating back to December 7, consistently stated they had no knowledge of who funded the operations. The scheme’s structure deliberately exploited the anonymity that digital asset payments provide to keep operatives disconnected from clients.

Police are now investigating whether the recent arrests connect directly to the December incident, where the same operational pattern appeared: property damage, threatening leaflets, and fractioned cryptocurrency payments distributed among three separate individuals.

Cryptocurrency Keeps Surfacing in the Country’s Recent Criminal Cases

The revenge-for-hire network does not exist in isolation. South Korea has accumulated a series of recent incidents where cryptocurrency appears tied to events that extend well beyond financial speculation.

Earlier in 2025, authorities charged a man with attempted murder after he allegedly mixed methomyl — a banned and toxic insecticide — into his business partner’s coffee. The trigger for the attack, according to investigators, was a dispute over losses from poorly managed Bitcoin investments. The case illustrated starkly how financial conflicts inside the crypto market can spill over into physical violence.


At the same time, the country’s regulatory environment endured its own stumbles. South Korea’s National Tax Service published an official press release that accidentally included the seed phrase for three digital wallets holding tokens valued at approximately $4.8 million

A seed phrase is the master key that grants full access to a wallet and allows anyone who holds it to drain the funds entirely, which turned the government’s own announcement into a significant public vulnerability. In a separate case, an individual lost access to Bitcoin valued at $1.4 million — funds that remained locked for more than four years.

The thread connecting all of these episodes is not the technology itself, but the way different actors exploit its specific properties. The for-hire harassment network chose cryptocurrency because money moves without leaving a conventional paper trail, clients stay invisible, and operatives work without knowing who employs them

South Korean police are working forward from the arrested operatives, but the core of the operation — whoever commissioned and financed the attacks — still has no face and no name. Whether investigators manage to cross the anonymity barrier that cryptocurrency created depends, in large part, on the traces the accused left behind without realizing it.
