The information listed below is mainly used to enhance the public's understanding of cybersecurity threats and help individuals and companies raise their awareness of prevention. Do not use it for any illegal purpose or attack activities. Digital identity theft may usually involve the following methods and technologies. Understanding these methods will help prevent and respond to cybersecurity threats: 1. Phishing: • Attackers pretend to be trusted institutions (such as banks, social networking sites or well-known e-commerce companies) and trick victims into clicking malicious links or entering sensitive information through emails, instant messages, and text messages. • This method often takes advantage of people's trust in familiar brands, causing victims to disclose their accounts, passwords, and other personal information. 2. Malware and Trojans: • Attackers install malware on victims' devices without their knowledge by sending emails containing malicious attachments or links, bundling software, or fake downloads. • Once installed, these software may record keyboard input (keyloggers), capture screens, steal credentials saved in browsers, or monitor network communications, thereby obtaining digital identity information. 3. Keyloggers: • Some malware is specifically designed to record user input, including passwords, browser URLs, and other sensitive information. • Keyloggers can be implanted on target computers through vulnerability hacking, malicious attachments, or fake software. 4. Man-in-the-Middle (MITM) attacks: • Attackers secretly intercept or tamper with the content of data transmitted between communicating parties. • In an unsecured public Wi-Fi environment or unencrypted communication, attackers may intercept authentication information and session tokens transmitted between users and websites, and then obtain digital identities. 5. Social Engineering: • In addition to technical means, attackers often use psychological manipulation, such as impersonating technical support or other authority personnel to trick victims into providing sensitive information over the phone or online chat. • This method often does not rely on intrusive technology, but instead uses human trust and sense of urgency to achieve its goals. 6. Data leakage and warehouse attacks: • Attackers steal batches of user data by hacking into databases or exploiting security vulnerabilities in third-party services. • Once the data of a website or service is leaked, attackers often use known usernames and passwords to implement "credential stuffing" attacks on other platforms. 7. Cookie hijacking and session hijacking: • When users visit websites in an unsecured network environment, attackers may intercept or steal session cookies in the browser. • After obtaining these cookies, attackers may pretend to be users and gain unauthorized access. 8. SIM card cloning or mobile phone number spoofing: • For systems that use mobile phone numbers for secondary verification, attackers may clone SIM cards or use voice spoofing to obtain victims' SMS or verification codes, thereby controlling accounts. It should be emphasized that although the above describes common methods of stealing digital identities, in reality attackers often combine multiple technologies and methods to carry out attacks. For ordinary users, raising awareness of network security is the key. It is recommended to take the following preventive measures: • Establish a sense of suspicion and do not easily believe in information or links from unknown sources; • Update software and operating systems regularly and apply patches in a timely manner; • Use complex and unique passwords and enable multi-factor authentication (MFA); • Be highly vigilant about sensitive information and avoid performing sensitive operations in public or unsecured network environments; • Regularly monitor and check abnormalities such as login and activity records of personal accounts. This article is only for the purpose of understanding and studying cybersecurity threats and risk prevention. Any illegal use of the above information is illegal and unethical. Users who are interested in learning more about cybersecurity protection technology are advised to study and research under the premise of abiding by the law, paying attention to ethics and following the guidance of formal training institutions.
