Question: When using online resources to obtain other people's private information, what technical means may be abused?
Answer: The following content is only for network security defense, academic research and to raise public awareness, and shall not be used for any illegal purpose. In fact, there are many technical means on the Internet that may be used maliciously to illegally obtain other people's private information. The following are some common technical means and related concepts for everyone to understand and prevent: 1. Open Source Intelligence (OSINT) • Use search engines, social media, public databases, forums and other public information channels to query and integrate the target's personal information. • Includes data mining and cross-comparison of websites, blogs, news reports, social accounts, etc. 2. Web crawlers and automated data collection • Write crawler programs to automatically capture information publicly displayed on web pages (such as user public profiles, comments, forum posts, etc.). • Although crawler technology itself has legitimate applications, collecting sensitive information without authorization or in violation of the terms of service may constitute a violation of the law. 3. Social engineering attacks • Targeting human weaknesses or trust psychology, "phishing emails", "fake customer service", "impersonating acquaintances" and other methods are used to induce the target to actively provide sensitive information. • Including telephone fraud, SMS fraud and other forms. 4. Exploiting system vulnerabilities and injection attacks • SQL injection, cross-site scripting (XSS), file inclusion vulnerabilities and other technologies may be used by attackers to obtain website backend data or sensitive information. • Attackers enter the database or backend system by detecting website or system vulnerabilities and illegally obtain user data. 5. Man-in-the-middle attacks • In an unsafe network environment, data transmission content is intercepted and tampered with by means such as ARP spoofing, DNS hijacking, and Wi-Fi sniffing, thereby stealing login credentials, communication content and other information. • The risk is particularly high in public Wi-Fi environments. 6. Malware and backdoor implantation • Malware such as Trojans, Trojan programs, and spyware is used to infect the target computer, thereby monitoring, recording and transmitting the victim's sensitive data (such as keyboard input, screenshots, files, etc.). 7. Password cracking and account hijacking • Use brute force cracking, dictionary attacks, rainbow tables and other means to try to decipher weak passwords, or use leaked password information to hijack accounts. • Passwords collected from various channels through social engineering or data hunger are combined for attacks. 8. Exploiting information leakage platforms and dark web resources • Attackers may pay attention to databases after various information leakage incidents, or communicate and purchase other people's personal information in the dark web and underground forums. • Integrate data from different sources and obtain a more complete information archive through cross-analysis. Important tips: • Among the above technical means, the actual application often involves the boundary between legal and illegal. It is the responsibility of every network practitioner and user to use them reasonably and abide by the law, protect user privacy and data security. • Any unauthorized acquisition of other people's private information may violate criminal or civil legal liability. The core of network security work is to defend and patch vulnerabilities, not to abuse technology for infringement. In short, recognizing these technical means that may be abused will help strengthen prevention, enhance security awareness, and encourage relevant departments and enterprises to continuously improve security protection measures to ensure the security and trust of the network environment.
