Ecco uno script che ho fatto "prima" (cioè anni e anni fa) per rimuovere fastidiosi 404 dal registro degli errori di Apache.
#!/usr/bin/perl -w
# ===========================================================================
# Author: David Tonhofer
# Rights: Public Domain
#
# Script kiddies and worms often try URLs behind which one can find
# specific vulnerabilities. This script writes a file to stdout that can then
# be included by httpd.conf so that known probed URLS result in 410s.
#
# See also: http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html:
#
# 10.4.11 410 Gone
#
# The requested resource is no longer available at the server and no
# forwarding address is known. This condition is expected to be
# considered permanent. Clients with link editing capabilities SHOULD
# delete references to the Request-URI after user approval. If the
# server does not know, or has no facility to determine, whether or
# not the condition is permanent, the status code 404 (Not Found) SHOULD
# be used instead. This response is cacheable unless indicated otherwise.
#
# The 410 response is primarily intended to assist the task of web
# maintenance by notifying the recipient that the resource is intentionally
# unavailable and that the server owners desire that remote links to that
# resource be removed. Such an event is common for limited-time, promotional
# services and for resources belonging to individuals no longer working at
# the server's site. It is not necessary to mark all permanently unavailable
# resources as "gone" or to keep the mark for any length of time -- that is
# left to the discretion of the server owner.
#
# WHY IS THIS INTERESTING
# -----------------------
#
# This setup removes the requests from the Apache httpd error log (the
# requests no longer generate 'file not found' errors)
#
# This is is a good thing insofar as that list then becomes smaller (good
# for maintenance) and someone trying out more 'refined' vulnerabilities
# becomes visible (good for ringing the warning bell). It also tells
# script kiddies to go look elsewhere. On the other hand, a notable
# increase in probing might go unnoticed.
#
# If the website is configured to redirect requests for unknown URLs to the
# homepage, having this script saves on bandwidth for sure.
#
# Notes
# -----
#
# Probes for errors in HTTP protocol handling (bad headers etc) will still
# show up in the log.
#
# -> analog webanalysis: The files still appear in the analog "failure
# request" log except if you set "STATUSEXCLUDE 410"
#
# -> You want to allow some URLs which are being probed as you really
# might have the corresponding application installed (patched and
# secured beforehand of course). Sometimes, adding further path elements
# might be a solution to discriminate legit requests from probes.
#
# -> Performance impact? I have no idea.
#
# What matches
# ------------
#
# The "gone" URLs are just the start of URLs, so anything with an extension
# will also match. There generally is no need to put the values into goneMatch.
# If you list "/forum3" as "gone", then the following will be marked "gone":
#
# /forum3
# //forum3 (which reduces to /forum3)
# /forum3/x
# /forum3//
#
# but not
#
# /forum3alpha
#
# If the website is configured to redirect requests for unknown URLs to the
# homepage, having this script saves both on bandwidth and noise in the web
# statistics.
# ===========================================================================
use List::MoreUtils qw(uniq); # dnf install perl-List-MoreUtils
# Direct matching
# ---------------
@gone = makeGoneArray();
# Simply print the "gone" array; used when this script is reviewed
# for my $x (@gone) { print "$x\n" }; exit 1;
# Special matching ANYWHERE WITHIN AN URL
# ---------------------------------------
# Lines terminated with a "$" will only match at the URL's end
# (so "/data.tar" and "/data.tar?x=2" will match, but "/data.tar/foo" will not)
# Probes may check many versions of "phpMyAdmin" (like "/phpMyAdmin-2.6.0a" etc),
# so, that URL is in the "goneMatch" list
# 2014-07: Found a bot actually scanning for backup files in the root; added!
# 2014-08: Various scans for "login.php" added.

# PRINT RESULTS.
# --------------
# The result is supposed to be installed by another script. The installer
# checks whether the script currently in use has different content than
# the new one, installs it of yes and then runs a graceful restart of Apache
# httpd. It also replaces %COPYMARK% with a tag indicating the installation
# operation datetime.
# TODO: One should suppress "sub-URLs" which are are subsumed by shorter
# ones but keep them in the list in case one would like to be more precise
# and remove the subsuming URL in the future.
print "# --------------------------------------------------------------------------\n";
print "# Use the perl script 'kiddie_be_gone.pl' to generate the contents below,\n";

#
# See "http://httpd.apache.org/docs/2.2/mod/mod_alias.html#redirect" redirect instruction
# Access to URLs yields error 410 - "Resource gone, no forwarding address"
#
# It would be cool to return a custom error code "444" - probe URL for example, but that
# does not seem to be possible.
#
print "Redirect gone $entry\n";

# Function to set up the URLs to which one responds "gone".
#
# "/\.ht" matches URLS which contain "/.ht", e.g. "/.htaccess"
# "/\.svn/" matches URLS which contain "/.svn/", i.e. anything requesting stuff under .svn
# "/\.svn$ matches URLs which terminate in "/.svn", i.e. the request for the dir itself
# (What about requests for "encoded" URLs? like "/.s%76n/"? They seem to be caught, too)
#
# This list is at the end of the script for easier editing and subsequent appending
# using the usual Unix text processing tools.
#
# Use "sort --unique" on the array to manually recreate the list.
