Sophos: 25-year-old mega-spammer arrested by japanes police

February 2008 by Sophos

According to media reports, police in Tokyo, Japan, have arrested 25-year-old Yuki Shiina following a complaint last year by an internet service provider (ISP) that he was sending huge amount of spam emails advertising gambling and dating websites. Police believe that Shiina bought 600,000 email addresses off the internet for 100,000 yen (USD 927) and earned over 2 million yen (USD 18,540) through the spam campaign.

It is claimed that Shiina faked the sender information on the emails in an attempt to avoid detection, breaking Japanese laws.

"Spammers believe they can escape the long arm of the law by hiding on the internet, but increasingly the authorities are cracking down on this kind of net abuse. No-one who hears about a single person believed to have sent 2.2 billion spam emails can be in any doubt as to the scale of the problem, and it’s essential for the police to send out a clear message that they are serious about catching the criminals responsible," said Graham Cluley, senior technology consultant for Sophos. "Legitimate businesses need to make sure that they are abiding by the law, and be careful not to hire firms and third-party individuals to market their websites or goods via junk email."

Last month, in a separate case, Sophos reported on the first arrest in Japan of a malware author. Kyoto police uncovered a plot to infect users of the P2P file-sharing network Winny with a Trojan horse that displayed images of popular anime characters while wiping music and movie files.
