An ‘etrecheck’ report on ASC Being an Apple Launch Daemon, of course, the cleanupinstaller.plist is owned by root: -rw-r--r-- 1 root wheel 446 Oct 10 06:52 com.apple.installer.cleanupinstaller.plist After discussion with a few colleagues about this oddity, I decided to see if I could catch a copy of the missing program argument. After rolling back to an earlier version first, I found that the macOS Install Data folder is created when a user runs the Upgrade installer (along with the Launch Daemon plist). A clean install with the full installer does not appear to create either the properly list or the program argument. The Locked Files folder indicated in the program argument path is hidden in the Finder, but revealed in Terminal. Inside the Locked Files folder is the cleanup_installer binary. The binary is 23kb, and the strings section contains the following, giving some indication of its purpose: Upon a successful upgrade, the /macOS Install Data/ folder is removed, but the Launch Daemon is not, and therein lies the problem.

It’ll execute whatever is at the program argument path with root privileges. With the executable missing as noted in numerous ASC reports, that leaves open the possibility that a malicious process could install its own executable at the path to aid in persistence or re-infection if the original infection were to be discovered or removed. To test this hypothesis, I threw a quick script together that included a ‘sudo’ command. /bin/bash sudo launchctl list > /Users/phil/Desktop/securityhole.txt The legacy command ‘launchctl list’ produces different results when it’s run with sudo and when it’s not. Without sudo, it’ll just list the launchd jobs running in the user’s domain. With sudo prepended, however, it’ll instead list the launchd jobs running in the system domain. This makes it easy for us to tell from the output of our script whether the job ran with privileges or not. Having created my script, I created the path at /macOS Install Data/Locked Files/ and saved the script there as ‘cleanup_installer’. Best steam mac games free. It’s worth pointing out that writing to this path requires admin privileges itself, so this issue doesn’t present any kind of ‘zero day’ possibility.
