I am writing a bot search and log module for my board.
Looking for stuff to find new search engines and add them to the search engine admin list. (I will write this mod eventually but I bet somone can do it faster than I can. I do have it working now though.
Anyway, checking through the clicklog for potentials I found this:
| Code |  |
91.207.6.170|1325502722|/yabb2/YaBB.pl?num=XXXXXXXXX||xpymep.exe
Several hits from this guy, I searched out xpymep.exe to be an xrumer exec
I added xpymep.exe to my main .htaccess to auto ban anyone that shows up with that.
If you want to stop xrumer users that is a potential way of doing it.
perhaps I ought to put the stuff I use to auto ban things in here also:
(this stuff works for me, but needs editing to work for you if you use it, please take extreme caution in re-programming it to your site)
trap.cgi (located in the cgi bin)
| Code | |
#!/usr/bin/perl
$basedir = $ENV{DOCUMENT_ROOT};
$htafile = "/\.htaccess";
$termsfile = "/badbot\.htm";
# Form full pathname to .htaccess file
$htapath = "$basedir"."$htafile";
# Form full pathname to terms.htm file
$termspath = "$basedir"."$termsfile";
# Get the bad-bot's IP address, convert to regular-expressions
#(regex) format by escaping all periods.
$remaddr = $ENV{REMOTE_ADDR};
$remaddr =~ s/\./\\\./gi;
# Get User-agent & current time
$usragnt = $ENV{HTTP_USER_AGENT};
$date = scalar localtime(time);
# Open the .htaccess file and wait for an exclusive lock. This
# prevents multiple instances of this script from running past
# the flock statement, and prevents them from trying to read and
# write the file at the same time, which would corrupt it.
# When .htaccess is closed, the lock is released.
#
# Open existing .htaccess file in r/w append mode, lock it, rewind
# to start, read current contents into array.
open(HTACCESS,"+>>$htapath") || die $!;
flock(HTACCESS,2);
seek(HTACCESS,0,0);
@contents = <HTACCESS>;
# Empty existing .htaccess file, then write new IP ban line and
# previous contents to it
truncate(HTACCESS,0);
print HTACCESS ("SetEnvIf Remote_Addr \^$remaddr\$ getout \# $date $usragnt\n");
print HTACCESS (@contents);
# close the .htaccess file, releasing lock - allow other instances
# of this script to proceed.
close(HTACCESS);
# Write html output to server response
if (open(TERMS,"< $termspath")){
# Copy the terms.htm file as output here.
print ("Content-type: text/html\n\n");
seek(TERMS,0,0);
@contents = <TERMS>;
print (@contents);
# close the terms.htm file.
close(TERMS);
}
else{
# if we can't open terms.htm, output a canned error message
print "Content-type: text/html\n\n";
print "<html><head><title>Fatal Error</title></head>\n";
print "<body text=\"#000000\" bgcolor=\"#FFFFFF\">\n";
# tell them something, I chose a joke
print "<p>Fatal error: See instructions on page 3 or enter any key.</p></body></html>\n";
}
# trying to send an e-mail message
open(MAIL, "|/usr/sbin/sendmail -t") || die "Content-type: text/text\n\nCan't open /usr/sbin/sendmail!";
#edit the email stuff to reflect you
print MAIL "To: me@myemail\.whatever\n";
print MAIL "From: me\@myemail\.whatever\n";
print MAIL "Subject: You caught another one!\n";
print MAIL "The ip address \^$remaddr\$ has been banned on $date \n";
print MAIL "The associated user agent was $usragnt\n";
close(MAIL);
exit;
add this type of line to .htaccess:
| Code | |
<Files .htaccess>
order deny,allow
deny from all
</Files>
# Block bad-bots using lines written by trap.cgi script above
SetEnvIf Request_URI "^(/403.*\.shtml|/robots\.txt|/badbot\.htm|)$" allowsome
<Files *>
order deny,allow
allow from env=allowsome
deny from env=getout
Deny from env=spam_bot
</Files>
RewriteEngine on
# xrumer captcha defeater
#edit the mydomain info
RedirectMatch xpymep.exe http://mydoman.place/cgi-bin/trap.cgi
RewriteRule !^(.*)403\.shtml - [C]
RewriteRule !^(.*)trap\.cgi - [C]
RewriteRule (.*) http://mydomain.place/cgi-bin/trap.cgi [L]
ErrorDocument 403 http://mydomain.place/403.shtml
badbot.htm:
| Code | |
<html><head><title>Fatal Error 693: Bad trip sense</title></head>
<body text="#000000" bgcolor="#ffffff">
<p>Fatal Error: See instructions on page 3 or enter any key.<p>
Something for spambots to choke on:<br>

potential spammers to help report themselves.<p>
I have other things in there for them also but that is the basic nutshell.
