Double extension files

Post by bas60 » 09 Feb 2020 18:23

I know there has been a lot of discussion on double extension files
I'm not 100% sure what the status is

Prefer not to completely disable it unless necessary

Most of the time double extension files is not a problem - even "...docx.pdf" once I explain the danger of possible hidden files

Most users understand

Last week a file with "January report %2008.pdf" was BLOCKED because of double extension!!

Why is % treated as an extension??

(1) is there a up-to-date recommendation on tweaks so ...docx.pdf type files are not blocked but ....docx.exe are?
(2) is it possible to disable the rule for a specific email domain - I have 6 domains on the filter
(since the number is small I can work with variation ie. allow only on domain...)

January report %2008.pdf was a double extension ? :o :shock: :?

That sounds like a bug :roll:

We need to squish that bug :dance:

1) That gives me an idea...
2) Yes, with a ruleset you can do that.
