About this tag
Credential attacks, including password spraying and legacy authentication abuse, are a major threat to Microsoft 365 and Entra ID environments. Recent campaigns like UNK_SneakyStrike targeted over 80,000 accounts using legitimate tools such as TeamFiltration. Microsoft is responding by blocking legacy protocols like RPS and FPRPC as part of its Secure Future Initiative. Vulnerabilities like CVE-2025-24071 in Windows File Explorer can also leak NTLM hashes, enabling further credential theft. Botnets have been used to scale password spraying against Microsoft 365 apps. Defending against these attacks requires modern authentication methods, strong password policies, and monitoring for anomalous login patterns.
