So is dropbox stealing your data or just syncing with a designated folder?
Well of course dropbox could steal your data.
After all it does require an installation on your system.
This is in-fact a system-wide process alerting it is accessing a new file.
The Dropbox shell extension thats most likely triggering these events as described in@razvanhs Medium explanation.
the software routinely communicates with its sync infrastructure at Dropbox and AWS (AWS CloudFormation) endpoints.
Is it possible to test this hypothesis, yes.
Dropbox only sent a few hundred KB after accessing the target file.
Similar to communications patterns when Dropbox is doing routine server checks.
According to this evidence Dropbox only sent a few hundred KB after accessing the target file.
The same patterns when Dropbox is doing routine server checks.
But that is to be expected with applications of this nature that sync data.
A better question is could they.
Short answer, yes, any third-party utility that utilized OS level monitoring tools can.
Long answer no, but not for technical reasons.
