I plan to use tool to prevent following file extensions from being created but concerned
that it may impact legit software/apps. Anyone know if there's any adverse impact.
We have implemented things that cause big disruptions which we now need to be careful.
Don't have a complete list of software we use but offhand, we hv MS Office Suite (incl Outlook),
a few users use media player/access Youtube (so not sure if preventing .mp3 from being
created will be an issue) & Adobe reader, archiving tools (winzip), various McAfee security
agents/tools in our PCs, DLP, Acronis, Checkpoint disk encryption, 2FA softwares.
Mostly on WIn 7 but may have some going to Win 10.
Below is the list of extensions :
.locky
.micro
.zepto
.axx
.cerber
.ecc
.crypt
.ezz
.r5a
.exx
.ccc
.crypz
.cryptowall
.enciphered

Cause when you block file creation based on that extension, then you may end without any files after a ransom ware attack.
Cause I would expect that the original file is either deleted before the encrypted file is saved or the original file is overwritten and then renamed.
So in the end, I don't think that this will increase security.
