I’m registered as a forum user on computergames.ro, a pretty big forum on our romanian internet and today, to my very dislike, I received an email from them, a weekly newsletter, because, they say, I registered for their newsletter.
Right. And pigs fly.
Needless to say I added them too to my “idiot email spam filter”.
Misusing their email database is at least “low” if not even breaking their own privacy rules. What the hell are these guys thinking anyway?
I really got to make some time to implement my global fight-spam-with-spam network. I don’t think these idiots will ever learn until they get a taste of their own medicine. More on that here: http://www.ciuly.com/anti-spam/introduction/

New anti-spam rules on forum
Wednesday, December 22nd, 2010A few days ago I started receiving a bit too many new user registrations so … as usual, I did something about it.
Long story short, here’s the link: http://forum.ciuly.com/index.php?topic=318.0

Finally happy with the forum anti-spam
Friday, September 24th, 2010I am finally happy with the akismet anti-spam solution I installed on the forum. Even though the idiot spammers succeed to register and post, their posts don’t show up.
A+ for this akismet thing. Great stuff indeed.

Some improvement on forum
Saturday, August 21st, 2010I started getting some stupid spam bots registering and after a few days spamming the forum, so I installed a few packages to deal with the issue, including the Akismet one. Hopefully this will put a stop on the spam on forum-side.

*.ru sites are now banned from my emails
Thursday, February 4th, 2010After banning *.cn sites, it’s high time for the russians to go as well. I am truly sorry innocent russian people who want to email me their website: I no longer accept such emails. Notice that I am taling about websites contained in the email, not email addresses or other stuff 😉

Where is the spam comming from?
Monday, November 16th, 2009For a good few weeks or even 2 months now I am getting a lot of “canadian” spam. mainly pills and shit. I was wondering wtf happened when it suddenly hit me. I had a canadian client in the medical area which basically ditched me for whatever reasons, totally unprofessional. Now that I think about it, he might have something to do with this.
And if he does and he has indeed something to do with this, I have only one question: Are you fucking out of your mind?!
I have an idea of a pretty good anti-spam filter for these emails (they all share some stuff but it’s not easy to get it strait out). So in the following 1 or 2 weeks I’ll write it and then, up yours.
I’ll probably make a dnsbl so that others can use it too.

Possible DOS attack caught on time
Thursday, October 22nd, 2009My server suddenly went under a very heavy load, similar with a DOS (Denial Of Service) attack. Luckily I was 1 foot away form it and heard the hard-drive working like crazy so I ssh-ed in the server, checked the running processes, noticed it was a high load on mysql (only possible via web), did a netstat, found the offending IP and temporarely -j DROP-ped it out with iptables. the load stopped suddenly so my finding was right.
this is the offending ip: 85.92.222.254
anyone know the guy behind it, hit him hard in the head.
will see if he returns and if he does, the -j DROP will become permanent.
Just for the record I currently have 7 IPs with permanent -j DROP . I should probably remove them since they are pretty old and with the use of DHCP the IPs probably belong to a ton of other people now.

My anti-bounce filter got its first false-positives
Saturday, July 25th, 2009I just noticed today that my anti-boucne filter is having a bit of a trouble with some false-positive. The trigger was that I received a paypal policy update email for one of my paypal accoutns (with an email hosted somewhere else) and the other one didn’t get it (email hosted on my server). So I got around digging and found that I missed about 6 valid emails and well over 30 spam messages (which would have been taken out by the anti-spam filters anyway)

Stupid spam-fighters [rant]
Thursday, July 16th, 2009I registered a little while ago on linuxforums.org to post my routing problem.
Imagine what, until I have 15 posts I cannot post any link. Not a problem, but guess what, even a simple thing like “dig domain A” which I need it in my explanation cannot be included because hell, it’s a link.
You stupid idiots, ever heard of false-positives? You’ve got a bunch of them.

One way spammers send “legitimate” spam
Wednesday, July 15th, 2009I wrote a full-blown smtp server for one of my clients, with some anti-spam and anti-abuse systems and I was contacted today by him because for some reason the server is sending a lot of spam out.
After some investigation we learned that:
– the spammers are using stolen credit cards to sign up to the paid server and get a user/pass used to authenticat
– since we deemed all paid customers as “good”, spam was getting out
– they quicly learned about the anti-abuse and stopped abusing the system in the obvious way, but still sending spam at the peak level so that the sytem would not pick up the abuse.
Basically, they stop wasting time to buy a domain and hosting and set it up for emailing, they buy directly a nice email account they can use. Cheaper, no time wasted to set it up and easy to ditch.
So, it seems we will be applying spam filters to all messages.
