TLDR: Old mouse event code in the JRE causes this prompt. AUSid hasn't been updated since 2017. I downloaded the dmg and extracted the contents, it's a launcher for a JavaFX application with a bundled JRE 8. The java code isn't obfuscated, and I don't see anything particularly interesting, but it would require going through a lot of code. However, the build and file modification dates are all 2017, which is pre-Catalina. Catalina of course introduced this permission warning. I instead did a quick Google for JRE bugs with this issue and it didn't take long to find this issue raised with OpenJDK: https://bugs.openjdk.java.net/browse/JDK-8231513 https://bugs.openjdk.java.net/browse/JDK-8231513 In particular, this comment: https://bugs.openjdk.java.net/browse/JDK-8231513?focusedCommentId=14295573&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-14295573 https://bugs.openjdk.java.net/browse/JDK-8231513?focusedComm... explains it's to do with mouse tracking around window resizing.
