If you weren't looking for adult content, why would a random MP4 find its way to your inbox? The Bottom Line
You click a link to "download" the video, but instead, you download an .exe or .zip file. Once opened, it installs a Trojan —a piece of software that gives a hacker remote access to your webcam, saved passwords, and banking info.
The file might be named 18yrBukkake.mp4.exe . Your computer might hide the .exe part, making you think it’s a safe video file.
