I am member of the team responsible for running https://www.peopleperhour.com and our users are telling us that our CloudFront domain ( dw3i9sxi97owk.cloudfront.net ) is being blocked by malwarebytes premium. This domain fronts a AWS S3 bucket where we upload "user generated content" such as profile avatar images and user portfolio items. Although we use a virus scanner, it is possible that a malicious user has uploaded malware to our CloudFront domain - we will be sure to remove anything suspicious immediately if you are aware of anything? It is in our interests this domain is clean and we certainly want to protect our users. The overwhelming majority of files will be safe so blocking the whole domain isn't necessary and makes our website ugly to malwarebytes users.
we had a similar problem in the past. ref. https://forums.malwarebytes.com/topic/247879-dw3i9sxi97owkcloudfrontnet-is-a-false-positive
As we were mentioned in the previous case we had, most of the files reported are only marked as malware by 1 engine, "Yandex Safebrowsing" and seem to be false positive any other file that is reported from more malware engines are already removed from our internal AV system.
Please let me know if there is something more to do to become unblocked by your system.
