We don't allow attachments with the extension exe here at vBulletin.org?

i was testing... this on some of my other sites (non-vb related) and hit this thing,
tried the same on my board and i was able to upload a renamed .exe to .jpg file

trying same on vb.org - It did not allowed.
Hence, i wanna implement same on my vb site and would also like to know the trick behind this

we are using the vb3 standart attachment system, so it may be just because of a thumbnail setting or something like.
At least i know i have not coded an exe file filter into vb.org ^^

Well i got my Apache.exe file and renamed it to Apache.gif and got this message.

Upload Errors
Apache.gif:
Not a valid image.

So if your running the latest vB then you have nothing to worry about.

maybe because the .exe isnt an image, even when replaced with a different extension? so when the server reads it finds out it isnt an image it gives you that error?

but the question was, how was the .exe file getting uploaded :S
thank You for ur time :)
