How we tested: a clean Debian 13 in a disposable container; source — package owncloud-client 5.3.2.15463+dfsg-1 from the Debian repository. Run as a regular user on a virtual screen, 60 seconds, nothing clicked. 19.10.2026. Every network request and every file written was recorded; the code was not decompiled. The container was deleted afterwards.
