Summary
Password spraying attacks have surged 155x in the first half of 2026, with a notable campaign generating over 81 million login attempts in two weeks. These attacks exploited legacy authentication and gaps in multi-factor authentication (MFA) policies. As a result, many organizations are left vulnerable to these types of attacks.
Attack Flow
IAM Impact
The surge in password spraying attacks highlights the importance of a robust identity and access management (IAM) strategy. Organizations with outdated authentication protocols and incomplete MFA configurations are particularly vulnerable to these types of attacks. As a result, IAM practitioners must prioritize the implementation of modern authentication protocols and ensure that all login flows are properly secured with MFA.
Key Takeaways
- Legacy Authentication Risks: Outdated authentication protocols are a major target for password spraying attacks.
- MFA Gaps: Incomplete or improperly configured MFA policies leave organizations vulnerable to these types of attacks.
- Continuous Monitoring: Regularly monitor login attempts and authentication protocols to identify potential vulnerabilities.
Recommendations
- Implement Modern Authentication Protocols: Replace legacy authentication protocols with modern, more secure alternatives.
- Ensure Complete MFA Coverage: Verify that all login flows are properly secured with MFA, including legacy authentication protocols.
- Regularly Monitor and Analyze Login Attempts: Implement continuous monitoring to identify potential vulnerabilities and detect password spraying attacks.
