Japan: Yusuke Katayama arrested in bizarre hacking case

JAPANESE police have arrested a man suspected of being behind a computer hacking campaign following an exhaustive hunt that at one stage had authorities tracking down a cat for clues, reports said.

Yusuke Katayama, 30, was arrested on Sunday on charges of using a remote computer and sending a mass killing threat to a comic book event after months of evading investigators with a series of vexing cyber riddles, according to NHK.

The broadcaster aired footage of detectives escorting a chubby man with glasses into a police station.

Katayama is believed to have sent numerous threats from computers around the country, including against a school and a kindergarten attended by Emperor Akihito’s grandchildren.

Japan’s Finance Ministry uncovers evidence of major Trojan attack

Japan’s Finance Ministry has uncovered evidence of a major Trojan cyber-attack on its computer systems that lay undetected for almost two years, according to local sources.

Ministry officials have admitted that the unspecified Trojan, which was not detected by the organisation’s security systems, was probably free to steal confidential data from January 2010 to November 2011,  after which the attack suddenly stopped.

A total of 123 computers inside the Ministry were infected out of around 2,000 so far checked, sources stated, which prompted the organisation to change hard disks on the affected machines.
