Random generated usernames

New thing I have noticed on my Kiwi:

|-----------> Last users

pony.brown 2022-09-01 09:17:00.361647

lily`jones 2022-09-01 08:08:32.753586

king`taylor 2022-08-31 17:55:21.852088

tank`henry 2022-08-31 12:20:54.784790

So this guy logs in with random usernames. Seems to be a kiwirecorder. What may the intention be?

I just blocked his IP now (was always the same IP)

Any ideas?

Comments

  • Would the IP be 149.248.51.191 ?

    That's the one I had yesterday. He is using vultr VPN and I have had the same random names before.

    I also blocked the iP.

  • Exactly!

    interesting that he faked usernames since usually there is no need to log in on a kiwi, is it?

    so he modified kiwirecorder (or is using a wrapper) to come up with a faked username. I wonder how this makes sense.

    I was going to repeat my constant refrain that once on the Vultr list you never come off but just checked firewall and last one I have listed is 167.179.65.161 end of last week. (no public Kiwi at this IP for ages).

    Will have to see if they are using a new IP range.

    --edit--

    Correction, I was looking at the previous log, seems they never give up..

    of course it's the same botnet that was running some time ago

  • 149.248.0.0/18 (0.0 to 63.255) added to blacklist

    @jks is there a place to report these clearly "spam" ip's or is it unwanted?

    207.246.64.0/18 (widened from 207.246.104.0/23) and 141.164.32.0/20 added to blacklist.

    @jks is there a place to report these clearly "spam" ip's or is it unwanted?

    The best we can do is maintain our own blacklist. Complaining to these hosting companies does nothing.

  • I see those two knocking on the firewall.

  • @jks, it would be nice if we can leave comments in the personal blacklist in the web interface about ip address. I update my blacklist very often. And I keep forgetting which addresses I add and for what reason. I think many people agree with me.

  • @jks Sorry I ment reporting them to you, not to the isp or cloud company.

    I think they don’t do anything illegal. It’s only annoying to us

  • Hi Andy. Okay, understood -- no worries.

    It's all just a big game of "cat and mouse" or "who can build the tallest wall/ladder". So we do what we can, while we can.

  • Hi

    Is it possible to add message YOUR IP IS BLOCKED ON THIS RECEIVER for local blacklist? What if you could add a reason for the block to be displayed to the user, like in the old days on IRC? ;)

    regards

  • I think this is not possible since the blocking is made on tcp level. See iptables -L -n and watch for "DROP". This is the best design since attackers are not able to reach the the Kiwi on its webserver.

    Showing a message box is like showing the middle finger but not best practice security wise :-)
