The information provided below is for security and educational purposes only and does not advocate or support any illegal behavior. Knowing these tips can help individuals and businesses improve their cybersecurity measures to prevent malicious attackers from obtaining account passwords. Common techniques include: 1. Phishing: Attackers use fake trusted websites, emails, or text messages to trick victims into entering sensitive information such as usernames and passwords on a fake login page. 2. Keylogging: Malware or hardware devices are used to record the victim's keyboard input to secretly collect passwords and other key information. 3. Malware and Trojans: Attackers use malware (such as Trojans and spyware) to infect victims' devices. These software can steal login credentials, take screenshots, or monitor activities in the background. 4. Brute-force and dictionary attacks: Use automated tools to try different password combinations (or use a dictionary of common passwords) to try to crack login passwords. This type of attack usually targets weak passwords or websites that are not properly restricted. 5. Man-in-the-middle (MITM): The attacker intercepts, intercepts or tampers with the communication content between the victim and the target server, especially in an unencrypted or weakly encrypted network environment (such as public Wi-Fi). 6. Credential stuffing: When other websites leak the user's username and password, the attacker uses these known combinations to try to log in to other platforms, because some users may reuse the same credentials on multiple websites. 7. Social engineering: The attacker uses psychological manipulation, such as impersonating technical support or other trusted identities, to guide the victim to actively disclose account information or click on messages with malicious links. Understanding and mastering these common attack methods can help users and organizations take corresponding defensive measures, such as using complex passwords, multi-factor authentication, keeping software updated, preventing phishing emails, using secure networks and security software, etc. Protecting your own information security is an important responsibility of every network user. Any malicious use of this knowledge is illegal and will be subject to legal sanctions.
