Hi,

Ah, WordPress. So many times I've seen compromised sites and servers that began with an incorrectly-configured, inadequately-secured or out-of-date WordPress install. Seeing 'php-cgi' by itself isn't necessarily sinister. WordPress is PHP based, and so any page you access will certainly spawn a PHP process somehow.

If your server is running Plesk (and from the 'sw-engine-fpm' process in one of your earlier process lists I'm pretty sure it must be), then this is a fairly standard way for Plesk to deal with PHP requests. Any request for a page that needs PHP to handle it will result in a 'php-cgi' process being spawned by Plesk, if it's configured to handle PHP in its usual way.

But I'd definitely start with that WordPress install, in terms of a suspect. At a bare minimum ensure it's up-to-date, that all its plugins are up-to-date (and that they are all legitimate and not malicious or suspicious plugins), that all your WordPress users and admins are ones you actually expect to exist , that they all have good strong passwords set, and so on and so forth. Pay very close attention to anything that allows file uploads in particular. Having anything that allows uploads of any sort without a username and password being required is a disaster waiting to happen, pretty much.

wbwd

WBWD(4) 						   BSD Kernel Interfaces Manual 						   WBWD(4)

NAME

     wbwd -- device driver for watchdog timer found on Winbond Super I/O chips

SYNOPSIS

     To compile this driver into the kernel, place the following line in your kernel configuration file:

	   device wbwd

     Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):

	   wbwd_load="YES"

DESCRIPTION

     The wbwd driver provides watchdog(4) support for the watchdog interrupt timer present on at least the following Winbond Super I/O chips:

     o	 83627HF/F/HG/G Rev. G
     o	 83627HF/F/HG/G Rev. J
     o	 83627HF/F/HG/G Rev. UD-A
     o	 83627DHG IC ver. 5

SYSCTL VARIABLES

     The wbwd driver provides the following options as sysctl(8) variables.

     dev.wbwd.0.timeout_override
	     This variable allows to program the timer to a value independent on the one provided by the watchdog(4) framework while still relying
	     on the regular updates from e.g.  watchdogd(8).  This is particularly useful if your system provides multiple watchdogs and you want
	     them to fire in a special sequence to trigger an NMI after a shorter period than the reset timeout for example.  The value set must
	     not be lower than the sleep time of watchdogd(8).	A value of 0 disables this feature and the timeout value provided by watchdog(4)
	     will be used.

     dev.wbwd.0.debug_verbose
	     If set this sysctl will tell the driver to log its current state before and after the timer reset on each invocation from watchdog(9)
	     to the kernel message buffer for debugging.

     dev.wbwd.0.debug
	     This read-only value gives the state of some registers on last update.

     The wbwd driver also provides further sysctl options that are hidden by default.  See the source code for more information.

HISTORY

     The wbwd driver first appeared in FreeBSD 10.0.
