Attachments now scanned for malicious content

[#1]

Hello.

In Trello starting this week, when you upload a new attachment, we are now scanning the file for abusive or malicious material. We do this for each file that appears as an attachment on the card back as well as the cover image.

If a file is marked as malicious, you’ll see an warning on the card back next to the file name as well as an alert badge on the card front.

We do not remove the ability for you to download the attachment.

Note: there may be a small delay between when the file is uploaded and when the flag appears.

Some software we just made ourselves (I believe without any malware in) is giving me this warning when I attach it in a zip to the trello card (HTML, CSS and JS in the zip).

Please can I have more information about what the scanning looks for, and the definition of "Malware" in this case? I don't want to release something containing malware to our end users, obviously.

☝️ For anyone finding this, I contacted Atlassian support and they gave some useful details about how the scanning works. Eventually I discovered this happens when files contain the string "EDIT_SERVER".
