Stolen credentials can enable account takeover and lateral movement; phishing-resistant MFA, password managers, and rapid revocation reduce the risk.

Background for this topic.
Credentials are the data used to verify a user's identity to a system, commonly including usernames, passwords, security tokens, or biometric identifiers. They serve as gatekeepers for access to accounts, applications, and sensitive information. Attackers target credentials to impersonate users, escalate privileges, or gain unauthorized system access.
Compromise of credentials can occur through phishing, credential stuffing, or theft from insecure storage. Effective defenses include enforcing strong, unique passwords, implementing multi-factor authentication (MFA), and securely storing credentials using hashing or encryption. Monitoring for unusual login patterns and promptly revoking compromised credentials are also critical to limit attacker impact.
Attackers are actively targeting various sectors across nearly 200 countries and already have compiled a list of working credentials for tens of thousands of compromised devices.
In addition to executing entirely in memory, the malware's infection chain incorporates other anti-analysis techniques designed to evade detection.
Google discovered and disrupted the sprawling campaign, which stole RedCAP credentials to breach numerous institutions and exfiltrate sensitive data.
