Is Lightshot (screenshot tool) safe?
Lightshot sends screenshot image data to its upload server over unencrypted HTTP.
When a user uploads a screenshot, Lightshot transmits the image as a binary POST to http://upload.prntscr.com over plain HTTP, with no transport encryption. The upload URL is hardcoded in the extension and includes a timestamp and an MD5-derived hash used only for path generation. On first upload, the extension also sends the user's OS and CPU architecture to the Lightshot API at api.prntscr.com along with a per-device identifier.

What this publisher told the store about itself, and the other listings that told it the same thing.
Shared hosts - 4 hostnames
Hostnames hardcoded in this extension that few other listings call. That can mean one operator behind both, and it can equally mean a small shared vendor, so it is context rather than a conclusion. Hosts that many listings call are left out: they are services, not connections.
