Japan Gives Jail Sentence to Crypto Miner in a Remote Mining Case

A Japanese district court has, for the first time, sentenced a man to prison in a remote crypto mining case. The case follows the arrests of Coinhive users by the police in 10 prefectures. However, this case is different from previously discussed cases of mining cryptocurrencies using website visitors’ computers.

Jail Sentence in Remote Mining Case

According to Nikkei, the Sendai District Court ruled on July 2, sentencing an unemployed 24-year old of the city of Amagasaki in Hyogo prefecture to one year in prison, with the sentence suspended for three years.

The Kahoku Shimpo publication elaborated:

The Sendai District Court ruled on an imprisonment sentence of 1 year, [with the] sentence suspended for 3 years…The judgment on mining abuse was the first in the whole country.
This news follows multiple other reports of the Japanese police cracking down on the use of remote mining tools where website visitors were not informed that their computers were being used to mine cryptocurrencies. Recently, the police in 10 prefectures nabbed 16 people and arrested three.

There is More to the Story

A source familiar with the matter explained to news.Bitcoin.com that this case involves the use of Coinhive in an online game cheat tool, instead of one installed on a website.

Kahoku detailed:

According to the judgment, he embedded a mining program into a tool that advances online games advantageously, in January – February, without justifiable grounds, released it on his blog, downloaded it to another person’s computer, and started mining.
Famous security researcher Dr. Takagi Hiromitsu commented on the news, confirming that “This case was not [about] Coinhive on the web but a cheat tool of an online game.”

Different Legal Status

Japan Gives Jail Sentence to Crypto Miner in a Remote Mining CaseLawyer Takashi Hirano believes that there is a legal difference between the two uses of Coinhive.

He represents Moro-san whom news.Bitcoin.com recently reported on. Moro-san was recently fined about $909 for installing Coinhive on his website and mined cryptocurrency without his website users’ consent.

Hirano reiterated:

I think that there are major differences in the legal configuration between using Coinhive on one’s website and embedding Coinhive in one’s cheat tool.
Furthermore, cheating programs for games are often illegal in Japan because they violate Japan’s Unfair Competition Prevention Law, according to Yomiuri Shimbun. Violators can be picked up by the police and charged with a crime.
