Hong Kong Wen Wei Po said that the computer systems of Cyberport and the Consumer Council in Hong Kong were hacked, and a large amount of confidential information was stolen and held for ransom. However, this is just the tip of the iceberg, and some corporate institutions have also fallen prey. Two school principals and small and medium-sized real estate brokers who became hackers confessed that the network vulnerabilities they exploited should serve as a warning to the public: the security systems were not updated for years and the employees had weak network security awareness, which led to the opening of links with viruses. Some experts have said that hackers are indiscriminately invading the networks of various enterprises and institutions, and many universities, primary and secondary schools, chain real estate companies, airlines, and even public institutions in Hong Kong have fallen victim. It is terrifying that even if the ransom is paid, the hackers will still publicly disclose and sell the confidential information. Therefore, companies must raise their security awareness. Hackers launch indiscriminate attacks, and seemingly unimportant middle schools that don't store too much confidential information have also become targets. A certain middle school in Kowloon was "plundered" by hackers early last year, and multiple important documents were stolen.
