It's often that someone uses "you must have watched too many sci-fi movies" to describe a person who is full of strange ideas. So when someone says, "You must have watched too many hacker movies!", we know for sure that this person definitely does not believe there are so many hackers out there. Movies are often based on real life, and hackers do exist around us just as depicted in the movies. On July 16th, Toshiba Corporation, a well-known semiconductor and electronics manufacturer, announced that a server of its subsidiary in the United States was hacked. The company's website registered personal information of 7520 customers, among which emails and passwords of 681 customers were leaked. There was no credit card information of customers on that server. A netizen revealed that it was rather ironic that Toshiba only found out about the information leak after the customer information was disclosed on a hacker website. In recent years, news of hacker intrusions has been common. At the beginning of July, the hacker group Anonymous played a big prank on Apple purely for entertainment purposes. And the most embarrassing hacking incident happened to Sony. From April to June, Sony suffered more than 10 large and small hacker attacks. Sony's websites such as Sony Pictures, Sony Europe, Sony Greece BMG, Sony Thailand, Sony Japan Music, and Sony Ericsson Canada all became targets of hackers. Some industry insiders analyzed that these attack incidents were retaliatory actions against Sony's lawsuit against hacker George Hotz, while others thought it was hackers showing off their ability to hack into servers. Regardless of the hackers' motives, the root cause of Sony's repeated network attacks was that Sony's system lacked stability and security and had poor defense capabilities, allowing people to take advantage of the situation. Moreover, Tencent also encountered hackers at the beginning of this year. The hacker infiltrated Tencent's server through a Linux vulnerability. He claimed that he just wanted to evaluate the security of the company's product, and would not engage in any malicious intrusion or destruction. He kindly reminded that if the vulnerability was maliciously used by others, it would pose a threat to users. Coincidentally, around the same time, NetEase also suffered from a hacker intrusion. The hacker called himself the Chinese Cyber Red Army and arrogantly left his contact information. In addition, Baidu was also subjected to illegal domain name resolution tampering by Iranian hackers last year, causing users to be unable to access the site for several hours. From this, we can see that China's network security situation is not optimistic. And the hacker problem is just one of the many network threats. Industry insiders pointed out that encountering network hackers can be attributed to two reasons: one is external factors. Nowadays, hackers' attack methods are becoming increasingly sophisticated. Even though many institutions have strengthened the management of their websites, hackers are like termites. As long as there is a place on the wood where the anti-insect paint is not applied properly, they can use that loophole to launch an attack. The second is internal factors. There are many human oversights in the server system, allowing hackers to take advantage of the situation. Nuo.cn, as an e-commerce expert, believes that not only servers have loopholes, but also the company's website code, space, and domain names are all targets for hackers. However, human oversights are sometimes hard to avoid. We cannot ensure that every operation is correct and safe. Therefore, enterprises should promptly discover and fix loopholes, update virus databases and attack programs in a timely manner, adopt intrusion detection systems and establish network security detection systems to strengthen the defense capabilities of the website, avoiding situations such as data loss, permission changes, and data tampering. In addition, in terms of informatization construction, service providers should be selected from various aspects such as professionalism, stability, expandability, security, and high configuration. The network has become the mainstream of this era. With the development of technology, the network is constantly evolving and its applications are becoming increasingly widespread. Although there are still many hidden dangers in network information security, we need to use it frequently, so only by continuously improving and strengthening network security defense measures can we effectively protect personal and corporate privacy data from being stolen.
