Odaily Planet Daily News: Cyber ​​hackers have recently launched frequent attacks on public and private institutions in Hong Kong, stealing personal information through network intrusions, publicly killing some of them after failed extortion, and auctioning the information of thousands of citizens on the "dark web". Recently, the Hong Kong Polytechnic and Luk Fook Jewellery were attacked by hackers, and about 450GB of files of the Hong Kong Polytechnic were posted on the dark web and made public. Nearly 10,000 people have viewed the information; some hackers claimed online that there were 5 million Luk Fook members' information for sale. Both institutions have called the police and notified the Privacy Commissioner's Office, and the Cyber ​​Security and Technology Crime Bureau of the police has taken over the investigation. It is reported that a hacker recently posted on Telegram that Luk Fook's member information was sold for 25,000 USDT (about 195,000 Hong Kong dollars). The leaked information includes the members' names, dates of birth, addresses, ID numbers, emails, account passwords, mobile phone numbers and WeChat accounts, including the personal information of mainland and local customers.
