Deckard Posted October 30, 2020 Posted October 30, 2020 (edited) Hello, we are offering a free online SaaS which also has the ability to upload pictures. This has now been abused for the first time by a 'spamvertisement' - so someone sending emails from a different server but in these email using images uploaded on our SaaS server. Is there a tool to reliably detect spamvertised images maybe on upload? Could this be solved server-side? Like blocking all images if they are trying to be loaded from outside our webpage? Any reasonable ideas would be appreciated. Thank you in advance Christian Edited October 30, 2020 by Deckard Quote

There was a tool I knew about years ago called dansguardian, but I am not sure if it is still a viable tool. I understand it could scan images. Quote
