Software pirates have a new foe in the form of Marcus Chu, the industry's latest weapon in the fight against Asia's notorious and growing illegal trade.
As the new software analyst consultant for the Software Piracy Association, Mr Chu works with the Customs and Excise Department to identify illegal products and provide expert testimony against alleged offenders in court.
His duties, which frequently take him into the territory's arcades in search of pirated goods, often leave him feeling ill at ease as his biggest fear is being recognised during undercover investigations.
'They're my enemies,' he said of the shopkeepers.
Mr Chu, an authorised technical examiner of association members' products, believed his knowledge of a wide range of software made him the ideal person for the job.
'It suits my interests. Because I like to play with software, this job is just perfect for me,' he said.
