[development] Fully patched site hacked and cloaked

[Nicolas Tostin]

Is it a good security tip to monitor the integrity of Drupal sources by
using MD5 hashes on the files ?
Is there a known/efficient way to achieve this ?

I just saw this performed on a D5 site. Bootstrap.inc was indeed altered, an
additional system.php file was inserted in the modules folder, and the
pernicious (drug) website files were inserted into the cgi folder *above*
the webroot. The code was sniffing passwords. Several files contained
nothing but hashes.

I mention this because if we see a pattern across many sites, this entire
conversation should move to security reports offline.
