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...
