The blog post by Shimon Brathwaite delves into various techniques used by attackers to gain credential access, such as brute force attacks, password store exploitation, and software vulnerabilities. It highlights the effectiveness of these methods, with over 80% of breaches involving brute force or lost/stolen passwords, and emphasizes the challenge in detecting such attacks due to their semblance to legitimate user activities. The article outlines several defense strategies, including using strong passwords, implementing two-factor authentication (2FA), encrypting sensitive information, and employing least privilege principles to limit account access. It also underscores the importance of monitoring for leaked credentials online and offers solutions like GitGuardian to prevent credential leaks through platforms like GitHub. By prioritizing these defensive measures, organizations can better safeguard against unauthorized access to their networks.
