Y3 mil reward offered for information in Trojan horse hacker case
The National Police Agency announced Wednesday that it will offer cash rewards to anyone who provides information leading to an arrest in the case involving personal computers infected with software that allows a hacker to control them remotely.
A reward of up to 3 million yen will be given to anyone who provides “concrete” information in the case of a hacker, in which four people have already been wrongfully arrested, NTV reported.
The Japanese reward system until now has been limited to information about murder, robbery and arson cases. The agency has now revised regulations to make the rewards applicable to cases involving Trojan-infected PCs.
The NPA was forced to apologize to the four innocent people who were arrested and accused of threatening and blackmailing corporations. The NPA now says it believes that pertinent information on the case may be outside the reach of regular investigative methods.
Officers wrongfully arrested the four in October for threatening messages that were sent through their personal computers using a Trojan horse. Their computers were located in Tokyo, Osaka and Mie prefectures, police said, causing fears that the hacker may have access to computers nationwide.
Unlike a virus, which attempts to infect other files, a Trojan horse, or Trojan, is a malicious application that appears to be a legitimate program but whose real purpose is often to grant a hacker unauthorized access to a computer.
The hacker has sent email messages to a number of companies and individuals, including a television station and a lawyer. Police say some of the emails, which claim the hacker has remote control of the recipients’ personal computers, were sent while the four wrongly-arrested individuals were under police custody.
