IntegraMOD

My server was recently exploited. It seems the exploit may have been from the includes/archive folder(s). Is there any way of checking this, and preventing it if necessary?

includes/archive may have been the result of your attack because there is no archive folder or file in the includes directory, unless you added it yourself while installing a mod

No, didn't add the folder, it was already there in IntegraMod 1.4.0

sorry, not too many ppl asking for 140 support, and it is not in 141. If your concerned about security, you should update to 141 because there are many insecurities in 140. This is however the first ive Ive ever heard of a problem stemming from that folder

Unfortunately, the upgrade instructions from 1.4.0 to 1.4.1 are pretty much guaranteed to wreck my site, simply because all existing files will be overwritten.
