Dropbox has come under fire from disgruntled techies about the company gaining access to PC and Mac operating system kernels.

Dropbox’s Project Infinite is aimed at shifting the service beyond being just a browser-based interface and integrating it more tightly with an OS so that files can be placed into cloud storage in a more seamless way.

It also wants this deeper integration with a computer’s operating system and local file storage so as to prevent, for instance, an inexperienced employee removing files from a shared Dropbox file.

But some observers say giving the cloud software access to a computer’s kernel layer potentially opens up the control layer to hackers.
