When targets follow malicious links or provide personal details, attackers gain access to accounts, leading to identity theft and significant financial impact.

Organizations can take proactive steps to mitigate phishing risks by implementing training programs that educate employees on recognizing suspicious communications. Additionally, utilizing email filtering tools can help detect and block potential phishing attempts.

Credential Stuffing

Credential stuffing is a cyber attack technique that involves using stolen username and password combinations to access multiple accounts. Cybercriminals capitalize on the fact that many users reuse their credentials across different platforms, making this method particularly effective. Once attackers gain entry, they can compromise sensitive information and wreak havoc on personal or organizational systems.

To safeguard against credential stuffing, organizations should enforce strong password policies and encourage the use of unique passwords for different accounts. Implementing multifactor authentication (MFA) adds another layer of security, making it more challenging for attackers to gain unauthorized access. 

Password Spraying

Password spraying is a prevalent technique used by cybercriminals that targets multiple user accounts with a few commonly used passwords. Unlike traditional brute force attacks that try numerous passwords on a single account, password spraying takes advantage of the fact that many users opt for simple, predictable passwords. This method significantly increases the likelihood of success because attackers only need one successful entry point to compromise a system, leading to unauthorized access and potential data breaches.

To combat password spraying, organizations should implement strong password policies that require complexity and discourage the reuse of credentials across platforms. 

Man-in-the-Middle (MITM) Attacks

Man-in-the-Middle (MITM) attacks occur when a cybercriminal secretly intercepts and relays communications between two parties. This tactic allows attackers to eavesdrop or manipulate information being exchanged, often without the knowledge of either party. For instance, during a public Wi-Fi session, an attacker can position themselves between a user and the network to capture sensitive data, such as login credentials or personal details.

To defend against MITM attacks, organizations should take the following precautions:

• Utilize secure communication protocols like SSL/TLS.
