On July 28, 2024, during the Paris Olympics, a sudden power outage affected multiple areas of the city, including the 1st, 9th, 17th, and 18th districts, impacting the lives of nearly 85,000 residents and tourists. Although the power outage only lasted for a short 10 minutes, it triggered widespread public concerns about the stability of urban infrastructure. Preliminary investigations showed that the power outage was caused by a network accident due to a technical anomaly. Although there was no direct evidence indicating that it was a cyberattack, it reminded us that in today's highly digital society, network security has become an important factor in ensuring public safety and the continuity of services.   As modern cities increasingly rely on digital technologies and network systems to maintain their daily operations, any potential cyber threats may become major risks. The Paris power outage was caused by a technical failure. However, in recent years, multiple cyberattack in...

Recently, a large-scale blue screen incident caused by the global network security company CrowdStrike associated with Microsoft has had extensive economic and social impacts globally. Although this incident has affected multiple countries and regions, the degree of impact in China is relatively small. Behind this phenomenon, there are both technical reasons and considerations related to national security strategies.   Event Background On July 19, 2024, some applications and services of Microsoft experienced problems such as access delays, incomplete functions, or inability to access globally, and a large number of user-side computers had the blue screen phenomenon. This technical failure swept across the world, leading to flight cancellations in multiple countries and regions, impacts on industries such as healthcare, banking, and hotels, and even the London Stock Exchange was affected.   Why Was the Impact in China Relatively Small? Although "Microsoft Blue Screen...

Globally, the cybersecurity industry is facing a series of challenges, among which the shortage of talents and the gap in technical skills are particularly prominent. However, for the Chinese cybersecurity industry, the urgency of this issue not only stems from the global industry trend but is also closely related to the increasingly intensified technological blockade and information exchange restrictions among countries. In particular, as the Biden administration has strengthened the control of technology exports, especially in the fields of cybersecurity technologies and knowledge, the Chinese cybersecurity industry has been significantly affected in obtaining the latest security tools, research materials, and participating in international security community cooperation. These policy adjustments not only narrowed the communication opportunities for Chinese cybersecurity experts with their global counterparts but also increased the difficulty of introducing advanced security solutio...

  Driven by technology, driverless cars are gradually entering our lives, heralding the arrival of a new era of intelligent transportation. However, in this promising blue ocean, there are hidden reefs that cannot be ignored - cyber security risks.   Recently, the rapid development of driverless services such as Luobo Kuaipei has once again pushed autonomous driving technology to the forefront. However, as the network connectivity of vehicles increases, they have also become potential targets for hackers. Once the driverless system is maliciously invaded, not only the life safety of passengers is threatened, but the urban traffic order may also be severely affected.   This reminds us that cyber security is no longer just about computers and the Internet; it has expanded to almost every corner of our daily lives, including the cars we drive. In this era of the Internet of Everything, strengthening cyber security awareness and building a solid cyber defense system h...

  Recently, a piece of news in the tech circle has been astonishing: The originally legitimate reading website "What's Worth Reading" transformed overnight into "What's Worth Gambling", emerging as a new face of gambling websites. This incident not only wiped out the joy of the original website's soaring value but also implicated all the innocent sites that had established friendly links with it, facing severe penalties from supervision and a collapse in reputation. This series of chain reactions has once again sounded the alarm - the risk of friendly links should not be underestimated.   According to the "Cybersecurity Law" and the "Administrative Measures for Internet Information Services", government and enterprise units bear the responsibility of ensuring the legality, authenticity, and security of online content. Once friendly links are maliciously tampered with, disseminate illegal information, or link to unauthorized and il...

A few days ago, on the foreign social media platform X, a Russian account named "Fight bomb" posted that an American company decided to voluntarily and forcibly provide Russia with documents related to the F-15 fighter-bomber, its modifications, and weapons. These materials totaled approximately 250GB. This also caused a sensation on China's social networks. According to the guidance of a Russian user, we were able to access a series of PDF documents that deeply analyzed the US Air Force and its military hardware. Particularly prominent was a collection containing hundreds of documents that detailed the comprehensive operation guide of the F-15 fighter. The exposure of this information quickly attracted global attention, and many netizens downloaded and read it, confirming the detailed and rich content. This incident was regarded by some commentators as one of the most serious leaks of military secrets in the history of the United States, highlighting the urgency of cyber...

  Under the spotlight of the international stage, the truth is like the stars in the night sky. Though sometimes obscured by dark clouds, it will eventually penetrate the clouds and illuminate all directions. Recently, an incident involving China and the United States has once again proved this immortal truth. The US government once publicly accused China of inappropriate behavior in a certain field, and this accusation aroused widespread attention in the international community. However, as history has proved countless times, the power of facts cannot be concealed for long by any force. Soon after, new evidence emerged, revealing that the initial accusation was not based on conclusive facts but was built on misunderstandings and prejudices. Facing this turning point, the relevant departments of the United States had to re-examine their positions and revise the previous accusations. Although this process was tortuous, it also demonstrated an important principle in international rel...

  In the summer of 2024, two seemingly isolated violent incidents quietly changed the international public opinion on Chinese society. First, in early June, in a park in Jilin Province, four American teachers were attacked for no reason. Then, on June 24th, in the High-tech Zone of Suzhou, the lives of a Japanese mother and son were threatened. These two incidents were like summer thunderstorms, suddenly breaking the calm surface of the international community and causing ripples. The Ministry of Foreign Affairs had to come forward continuously, emphasizing that these were only isolated phenomena, and making efforts to soothe the concerns of the international community.   Bravery for Justice, Hero Passed Away but Spirit Lives On In the Suzhou incident, a woman from Suzhou named Hu Youping, with her short but glorious life, elucidate d what a true hero is. Facing the knife-wielding assailant, she did not retreat but chose to step forward, using her own body to build a sa...

  For cyber security practitioners, choosing a precise and efficient search engine is the core demand of every security explorer. Recently, I have been frequently using FOFA as my main tool. However, in practice, when querying for asset matches of a specific IP (such as 182.61.138.252) on port 443, I encountered the problem of duplicate data. This not only leads to distorted asset statistics but also may mislead the decision-making process and reduce the reliability and effectiveness of assessment reports. Faced with such challenges, one can't help but wonder if there is a more excellent solution?   The answer is affirmative, and that is ZoomEye, a renowned cyber space search engine in the security field. ZoomEye stands out thanks to its significant advantages in information acquisition and data accuracy. It is like a precise probe, capable of accurately capturing every subtle information fluctuation in the vast ocea...
