To give you a little history, we recently heard from a major law enforcement agency about a massive attack on US financial institutions originating from our servers.

We did a detailed analysis of the attack pattern and found out that most of the attack was originating from CMSs (mostly wordpress). Further analysis revealed that the admin accounts had been compromised (in one form or the other) and malicious scripts were uploaded into the directories.
