Credential harvesting
Credential Harvesting
Credential harvesting, also known as credential theft, refers to a cyber attack method that involves stealing user credentials, such as usernames and passwords. Attackers use various techniques to obtain these credentials, which can then be used to gain unauthorized access to sensitive information, systems, or accounts.
How Credential Harvesting Works
Credential harvesting attacks can be executed using different methods:
Phishing: Attackers use deceptive emails, messages, or websites to trick users into divulging their login credentials. These phishing attempts often mimic legitimate entities, such as banks or social media platforms, to gain the user's trust and convince them to enter their sensitive information.
Keylogging: Malicious software, also known as keyloggers, secretly captures and records a user's keystrokes, including usernames and passwords, without their knowledge. This technique allows attackers to gather sensitive information as users enter it on their keyboards.
Brute Force Attacks: Attackers use automated software to systematically try many different password combinations until the correct one is found. This method relies on the assumption that some users have weak or easily guessable passwords, allowing attackers to gain unauthorized access.
Credential Stuffing: In this method, attackers use automated scripts to input stolen or leaked credentials from one service into another. They rely on the commonality of reused passwords among different services. If a user reuses the same password for multiple accounts, an attacker who obtained that password can try it on other services to gain unauthorized access.
Prevention Tips
To mitigate the risks associated with credential harvesting attacks, it is crucial to implement preventive measures:
Enable Multi-Factor Authentication (MFA): MFA adds an extra layer of security by requiring users to provide an additional form of verification, such as a one-time code sent to their mobile device. This helps protect against attacks even if the attackers manage to obtain the user's login credentials.
Use Secure Passwords: Encourage users to create and use complex, unique passwords for each service or account. Strong passwords should include a combination of uppercase and lowercase letters, numbers, and special characters. To manage these passwords securely, consider using password management tools that can generate and store strong passwords.
Educate Users: Provide comprehensive cybersecurity training to individuals to help them recognize phishing attempts, use caution when entering login credentials, and understand the importance of cybersecurity best practices. Regularly updating users about the latest phishing techniques and security measures can significantly reduce the risk of falling victim to credential harvesting attacks.
Related Terms
Here are some related terms that are relevant for better understanding credential harvesting:
Phishing: Phishing is the practice of fraudulently obtaining sensitive information, such as usernames, passwords, or credit card details, by posing as a trustworthy entity in electronic communication. Attackers often use deceptive emails, messages, or websites to trick users into sharing their confidential information.
Keylogger: A keylogger is a type of malware that records a user's keystrokes to capture sensitive information, such as usernames and passwords. Keyloggers are often deployed covertly and without the user's knowledge, allowing attackers to gather valuable data.
Brute Force Attack: A brute force attack is an attack where automated software repeatedly tries different password combinations until the correct one is found. Attackers use this method to gain unauthorized access to systems, networks, or accounts by systematically trying various combinations of usernames and passwords.
By familiarizing yourself with these related terms, you can gain a comprehensive understanding of the different techniques and methods employed in credential harvesting attacks.
