Credential Misuse

Summary

Credential Misuse is a type of application attack where an adversary exploits stolen, guessed, or otherwise obtained credentials to gain unauthorized access to systems, applications, or data. This attack often involves the abuse of legitimate user accounts to bypass security controls, escalate privileges, or exfiltrate sensitive information.

Key Characteristics

• Use of compromised or stolen usernames and passwords to authenticate.
• Exploitation of weak, reused, or default credentials.
• Often involves lateral movement within networks after initial access.
• May include abuse of privileged accounts to increase impact.
• Can be facilitated by phishing, credential stuffing, or brute force attacks.
• Hard to detect due to the use of legitimate credentials and normal login processes.

Defensive Controls

• Implement multi-factor authentication (MFA) to reduce reliance on passwords alone.
• Enforce strong password policies and regular credential rotation.
• Monitor and analyze login behaviors for anomalies and suspicious activities.
• Use credential vaulting and privileged access management (PAM) solutions.
• Deploy account lockout mechanisms after repeated failed login attempts.
• Educate users on phishing and social engineering risks to prevent credential theft.

Related Security Solutions

Credential Misuse is mitigated through solutions such as identity and access management (IAM), multi-factor authentication platforms, privileged access management (PAM) tools, security information and event management (SIEM) systems for monitoring, and endpoint detection and response (EDR) technologies that help identify suspicious activities associated with compromised credentials.
