Hello,
we use Acrobat and Reader as part of creative cloud in our company. In one department we view .pdfs with linked .docm/.doc/.xlsm/.xlsx/.pdf - files, in all others we only have .pdf to .pdf links. To prevent maleware to spread through attached files, we disabled opening non-.pdf-files and only allowed it in the mentioned department and activated sandbox / protected mode.
As this is an severe security problem and our company was targeted by a virus using this leak, I would like to limit this. Best case would be allowing only word and excel to be opened and only files from the directory the mentioned department works in.
- I tried to set up a whitelist ("ProtectedModeWhitelistConfig.txt"), which only led to unexplainable behavior (links to other directories than the ones listed in the whitelist would work rather than the allowed ones; powerpoint would open, excel would not).
- I tried to make the directory (on a server) a trusted "internet" source, as recommended in a discussion in this forum by an adobe employee, which would not work
- I tried to make the directory a trusted source in the extended settings, which would not work either
Can anyone relate or help?
I really need this to be solved in order to close this security leak and I think there are others with the same / a similar problem.
Thank you!
