I've recently been having an issue with someone having the ability to upload print.scr via an attachement, based on server logs they are gaining access by submitting a ticket. Steps I've taken so far:

-I've limited attachments to only (.gif,.jpg,.png,.doc,.docx,.xls,.xlsx,.txt,.pdf,.jpeg)
-Confirmed that I cannot submit an unapproved file type
-The only writeable files are the attachments, cache, and settings file is uploaded

Steps taken after the attack:

-Changed attachment folder name
-Verified all security permissions within IIS and Windows Server are correct
-I'm tempted to remove write access from settings.php and limiting myself to only changing it via the local server environment.

Is there anything known right now that can be an issue? Anything which I am forgetting?

Edit: My hosting company was able to identify how they got in, via IIS FTP service; it seems Microsoft has a vulnerability to fix.

The IP address for everyone to block is 91.185.42.76

Thanks,

Tom

There are no known security issues in Hesk.

I thought that might be the case. I've seen it happen before many times and the malware then tries to hide itself within other files/scripts on the server to mislead researchers into the actual source of entry.

Note that it probably is not an IIS bug, but a stolen FTP password. I would advise changing all your passwords and scanning your computers with up to date anti-virus software as some trojans are known for stealing FTP passwords.

Thank's Klemen for your response, passwords have all been changed and another 4 characters added to everything. This is the first time that I've seen malware specifically target only the inetpub/wwwroot folder.

Every other attack I've seen has been files and junk everywhere
