Zip files

[Robin Deatherage]

Does your agency allow or block zip file attachments on emails?  We have had viruses get in that were zipped and the user not realizing unzipped and infected their pc so I decided to block them.  Now I'm wondering if maybe I should reconsider.

Sounds more like a users need to pay attention and be more suspicious/training issue.

I've been blocking and refusing for almost 10 yrs now.  NO need and people still doing so need to adjust for today.   Not using dial up anymore and reason for compression.

Zip files are useful for sending multiple files as one attachment (organization). Compression isn't always the point these days, but can still come in handy when the recipient mail server has size restrictions.

I do not block. MX Logic scans in the cloud & symantec scans on the client. Not really afraid of it. Feel free to send me one of the eicar.zip files. might be a fun test for both ends.

Also, I've seen rare occasions where xlsx somehow comes through as a zip.

I'm not sure blocking zip is even worth the hassle these days... I think we might still do it here, but ppl just rename the file .piz or .zzz or something and send it on through.

A decent endpoint security product + some user awareness training should mitigate most of the risk.
