Potential exploitation of Click Studio’s PasswordState software

On 24 April 2021, Australian software company Click Studios announced a compromise of the software update process for their enterprise password management software PasswordState, used by organisations in Australia and globally.

Alert status


The compromise of Click Studios’ software update process in April 2021 has resulted in some PasswordState users downloading malware through the software update function. If executed, the malware leads to the compromise of the customer’s PasswordState instance, giving the malicious actor access to all passwords stored in PasswordState, and creates the opportunity for follow-on malicious activity.
