Filter spam messages based on text inside image?

[abdelhost77]

Hi,
Actually, my users are receiving "phishing" emails indicating that their mailbox has been hacked and that they should pay in bitcoin to some hacker to avoid account deletion.
The issue here is that the text body is inside an image "as an attachment", and each time it is coming from different IP/domain, so how can we filter this kind of spam, please?

If its the one I think it is, then you cant filter based on the text inside the image.
That would be like asking if you could filter if the image contained a car.
The filter isn't intelligent enough to determine the contents of an image.
You'll have to find some other way to filter it.

I'm not aware of any filtering system that will filter based on the text in an image, you can filter based on the fact it has an image though but you might be filtering legitimate mail too.
