Developing ransomware programs to infiltrate and extort enterprises, resulting in system paralysis and inability to operate normally; Creating a cheat program for account grabbing, which undermines the fairness of medical resource allocation; Implanting a "Trojan" virus into the monitoring system, causing long-term distortion of enterprise emission monitoring data... Recently, the Ministry of Public Security reported on the special work of the national public security organs' network security departments to promote the crackdown on cyber hacking crimes in 2024, and announced 8 typical cases of cracking down on cyber hacking crimes in accordance with the law. In the current wave of digitization, whether it is the production and operation of enterprises or the daily life of the people, the dependence on the internet is increasing. At the same time, the criminal activities of cyber hackers have become increasingly rampant, seriously threatening network security and the normal operation of the economy and society. The 8 typical cases announced this time are each shocking, involving amounts of millions of yuan, some even billions of yuan. These cases indicate that the harm of cyber hacking crimes has penetrated into all aspects of society. Taking one of the targeted fraud cases against a company's financial personnel as an example, criminals developed a "Trojan" virus to illegally invade and control the computers of the company's financial personnel. After stealing relevant data, they then impersonated the company's boss to carry out targeted fraud against the financial personnel. Due to the fact that criminals have access to precise data, the success rate of such fraud is often extremely high, which also has a serious impact on the daily operations of enterprises. As of the time of the incident, over 7200 companies nationwide have been infected with the "Trojan" virus. Fortunately, the public security organ took timely action, not only brought 17 suspect to justice, but also warned and dissuaded the companies infected with the "Trojan" virus, successfully stopped losing 265 million yuan, played a preventive role and effectively reduced network security risks. However, we must be soberly aware that cracking down on cyber hacking crimes cannot be achieved overnight, but is a long-term offensive and defensive battle. With the continuous iteration and upgrading of network technology, the means of hacking crimes are also constantly evolving, and their concealment, complexity, and harmfulness are increasingly increasing. On the one hand, enterprises need to increase their technological investment, improve their network security management system, build a strong network security defense line, and prevent hackers from taking advantage of it. On the other hand, it is also necessary for public security organs to continuously improve their technical level and investigative capabilities, and promote the formation of a comprehensive and multi-level joint force to combat cyber hacking crimes. Only in this way can we take the initiative in this war without gunpowder, allowing cyber hackers and criminals to be exposed, and making the internet truly an important force in promoting social progress and enhancing people's well-being.
