ACSC Releases Advisory on Password Spraying Attacks

Last Revised

The Australian Cyber Security Centre (ACSC) has released an advisory on password spraying attacks. Password spraying is a type of brute-force attack in which a malicious actor uses a single password against targeted user accounts before moving on to attempt a second password, and so on. This technique allows the actor to remain undetected by avoiding rapid or frequent account lockouts.
The ACSC provides recommendations for organizations to detect and mitigate these types of attacks against their external services, such as webmail, remote desktop access, or cloud-based services.
The Cybersecurity and Infrastructure Security Agency (CISA) encourages users and administrators to review the ACSC advisory on password spraying attacks and the following CISA tips:
•    Choosing and Protecting Passwords
•    Supplementing Passwords
