So, today an user sent me an e-mail about a suspicious e-mail. When I opened it to check it, I accidentaly hovered the mouse over the "doc.jpg" and it opened the image thumbnail. I never bothered to check the thumbnails, so I never stop to think about it, but would someone be able to execute malicious code in my computer if I checked the thumbnail?
