Hi, recently my server was hacked and used for spam sending through roundcube.... :-\ fortunately I discovered soon.
I'm still investigating, but the problem points to an old version of roundcube (0.8.x, 0.9.x) and the file:
roundcube/plugins/enigma/lib76.php
Any clues? I've been looking about this file and this plugin but i don't find this file in github, perhaps too old, the install was on november 2014
Thanks in advance!
There was never such a file in Roundcube. Probably has been somehow uploaded by the hacker.
Indeed, suspicios php files uploaded... all solved (I hope).
Thanks for quick response!
