As shown LuLu detects a connection, and despite blocking it, the rar file was unzipped.
The Unarchiver.app directly installed from the webstie seems to do two kind of connections:
- The first three (4, 68, 69) are "phone home" requests which seem to track that a user started the application and what they did with it. Each request itself consists of some identifiers (probably to identify the user) and the activity taken, see here for a full example.
- The last two check for update (it's actually just one request, #73 gets redirected to Amazon AWS)
The connection to sentry.io can be blocked (I used Little Snitch, you could also block it on your router or similar), it doesn't seem to impact the application.
