A businessman, who was found guilty of unleashing “highly reckless” cyberattacks on a stock exchange website last year, was sentenced to nine months in jail on Friday.

Tse Man- lai, who had pleaded not guilty to two counts of obtaining access to a computer with criminal or dishonest intent, was convicted of both counts in the District Court on October 24.

Tse, the 28-year-old owner of an information technology company, launched denial-of-service (DoS) attacks on HKExnews, a website providing information from listed companies, on August 12 and 13 last year.
