Ummmm -- the only part of that likely to be relevant here is the last.

These kinds of web page "compromises" are typically achieved through 
bad/ill-configured/non-updated server-side web applications (or their 
underlying script engines) and are typically achieved without requiring 
any more special or privileged access to the victim sites than the 
ability to run a clever Google search or your own brute-force spidering 
via a bot-net, etc.

Of course, simply removing the undesired iframe/script/etc tags from 
your compromised pages is not enough.  Although doing so does not mean 
that this attacker will come back, it equally does nothing to close the 
hole they used in the first place, and the next attacker searching for 
that hole will hit you just as easily and indiscriminately...
