Its php ffs

phpinfo will reveal if any extraneous libs are linked in.
A grep of its source code for any system() type calls will reveal if odd
ode is being invoked.

Ditto a code walk for any database open calls or CURL will check for
access to where it may or may not access.

If its beyond the OP, I suggest a paid contract to another contractor to
'find the bugs, and indentify the rubbish'

Set a thief to catch a thief.
