  • More sendmessage.php SPAM

    Greetings...

    I'm having similar sendmessage.php SPAM problems as others here on a board I administer for a client... about 100 in the past 2 months with about 80 different IP addresses. Lately they're about 4 in a batch, twice a day.

    It made me think back a couple of years ago at a similar problem I had from using the old wwwboard cgi script where these bots hit domainname.com and tried several different common posting strategies. At my current server logs confirmed my suspicion that the IP trail indicates the entrance of the culprit is directly to the domainname.com/sendmessage.php file.

    I am still running 3.5 awaiting a MySQL upgrade on the server to run vBulletin 3.6... oh, and my current Mac-based server setup doesn't support GD or ImageMagick.

    Since this SPAM is really annoying and I figured I'd try this experiment...

    I renamed the sendmessage.php file to something different, and changed the references in the template via the Style Manager to match that new name. So far, so good. My quandry is that there's a reference to sendmessage.php in the vbulletin_global.js file... but I can't seem to update that file due to permissions problems on the server... and of course I have little idea as to what that file does.

    Any feedback would be appreciated.

    Visit http://www.dnsstuff.com and perform an IPWHOIS lookup on the originating IP addresses of the emails. I'm willing to bet that they're all from Russia, Belarus or the Ukraine - that was the case with mne when I got hit about a month ago. They were hitting me, even with image verification turned on.

    If that's the case, add this to your .htaccess file.

    Code:
    # Block Eastern Europe hackers and spammers.
    <limit GET HEAD POST PUT DELETE>
    order allow,deny
    # Inhoster: Ukraine
    deny from 85.255.112.0/20 195.95.218.0/23 195.255.176.0/22
    # resolve.ru: Russia
    deny from 72.36.244.129/32 72.36.244.130/31 72.36.244.132/30 72.36.244.136/29 72.36.244.144/28 72.36.244.160/27 72.36.244.192/26
    # Prohosim: Russia
    deny from 207.58.178.0/24
    # TheZone: Bulgaria
    deny from 85.217.192.0/18
    allow from all
    </limit>
    
    # Block Intercage hackers and spammers.
    <limit GET HEAD POST PUT DELETE> 
    order allow,deny
    deny from 69.22.162.0/23 69.31.64.0/20 69.31.80.0/21 69.31.128.0/22 69.31.132.0/23 69.50.160.0/19 216.255.176.0/23
    allow from all
    </limit>
    According to that I've seen on a few other sites, Intercage has some sort of a relationship with Inhoster, which was the source of most of the "contact us" spam that we got.

      cyburbia,

      Thanks for the input! I do plan to block the IPs, but I delayed doing so as the problem has been until only recently have they used the same IP more than once.

      In fact, looking at my error logs for the last 36 hours, about 8 of the SPAM attempts occurred since I renamed sendmessage.php are from repeat-offender IP addresses.

      Notice the multiple hits from different IPs within a short period of time... this has been a signature pattern for this problem.


      Oh, and I relalize now I should have placed this thread in the version 3.5 forum... sorry about that.

        I didn't bother with the rest. Looks like they've gone fron static Inhoster IPs to zombies.

        And people think Americans are the most prolific spammers of the world ...
