In the process of stealing and selling digital information to obtain illegal benefits, attackers may use a variety of technical strategies. The following are some common technical methods： ### 1. **Phishing (Phishing)** -**Description**: The attacker uses forged emails, websites, or messages to trick the victim into providing sensitive information, such as user names, passwords, credit card information, etc. -**Example**: Fake the login page of a bank or social media and ask the user to enter credentials. ### 2. **Malicious software (Malware)** -**Description**: The attacker infects the victim's device through malicious software, steals data or controls the device. -**Example**: Keylogger records the user's keyboard input and steals the password; Ransom encrypts the user's files and asks for a ransom. ### 3. **SQL Injection (SQL Injection)** -**Description**: An attacker obtains or tampered with information in the database by inserting malicious SQL code into the input field of the Web application. -**Example**: Get the user name and password in the user table by injecting code. ### 4. **Man-in-the-Middle Attack (MITM)** -**Description**: An attacker intercepts communication between the user and the server and steals or tampered with the transmitted data. -**Example**: Intercept unencrypted communications in a public Wi-Fi network and obtain the user's login information. ### 5. **Social Engineering (Social Engineering)** -**Description**: The attacker uses psychological techniques to trick the victim into revealing sensitive information or performing certain actions. -**Example**: Impersonate a technical support staff, ask the user to provide a password or install malicious software. ### 6. **Credential Stuffing (Credential Stuffing)** -**Description**: The attacker used a combination of user name and password obtained from other data leaks to try to log in to other websites or services. -**Example**: Using a leaked email and password combination, try to log in to an online banking or social media account. ### 7. **Zero-Day exploit (Zero-Day Exploit)** -**Description**: An attacker uses software vulnerabilities that have not yet been exposed or patched to obtain unauthorized access or steal data. -**Example**: Use undisclosed vulnerabilities in the operating system to bypass security protections and steal sensitive information. ### 8. **Distributed denial of service attack (DDoS)** -**Description**: The attacker flooded the target server with a large number of requests, making it unable to provide services normally, thus creating conditions for other attacks. -**Example**: Through DDoS attacks, the security protection of the enterprise is invalidated, and the opportunity is taken to steal data. ### 9. **Data Breach (Data Breach)** -**Description**: An attacker obtains sensitive data of an enterprise or individual through a vulnerability or internal personnel leakage. -**Example**: Obtain user personal information and sell it through an unencrypted database or weak password. ### 10. **Network Scanning and Probing (Network Scanning and Probing)** -**Description**: An attacker uses a network scanning tool to detect vulnerabilities in the target system and look for intrusion points. -**Example**: Use tools such as Nmap to scan open ports and services for vulnerabilities that can be exploited. ### 11. **Insider Threat (Insider Threat)** -**Description**: Internal employees or partners of the company intentionally or unintentionally disclose sensitive information. -**Example**: Employees sell confidential company documents to competitors or hacker organizations. ### 12. **Password Cracking (Password Cracking)** -**Description**: The attacker guesses the user's password through brute force cracking or dictionary attack. -**Example**: Use Rainbow Table to crack the hash value and obtain the user's password. ### 13. **Session Hijacking (Session Hijacking)** -**Description**: An attacker accesses the system by stealing the user's session token and impersonating the user. -**Example**: Steal cookies in an unencrypted HTTP session and log in to your account as a user. ### 14. ** Cross-site scripting attack (Cross-Site Scripting, XSS)** -**Description**: An attacker injects malicious scripts into a Web page to steal user information or perform malicious actions. -**Example**: Inject scripts into forums or comment areas to steal visitors' cookie information. ### 15. **Data Encryption for Ransom (Data Encryption for Ransom)** -**Description**: The attacker encrypts the victim's data and asks for a ransom to be paid to decrypt it. -**Example**: Encrypting important documents of a company through ransom software and demanding payment of Bitcoin as a ransom. ### 16. **Supply Chain Attack (Supply Chain Attack)** -**Description**: An attacker indirectly attacks the target system by invading a supplier or a third-party service. -**Example**: Distribute malicious software to users by invading the software update server. ### 17. **Cloud Service Abuse (Cloud Service Abuse)** -**Description**: Attackers carry out large-scale attacks or data theft by abusing cloud service resources. -**Example**: Using cloud services for DDoS attacks
