Persistence through a Run key

Values under the Run and RunOnce keys start a program at every logon. A post-exploitation framework added one on two machines, once for all users and once for the current user, so that its agent starts again after a reboot. Installed software writes to the same keys: the clean Windows 10 client has entries from Dropbox, Spotify, Edge, Google Drive, KeePass and others. Find the two entries the attacker added.

Hint 1

TargetObject tells you where the value was written; Details tells you what will run; Image tells you which program wrote it.

Hint 2

Not every key with Run in its path is a Run key: look for RunTime and RunLogonScriptSync in the data.
