• Telnet attacks - what I use

    From John Riley@21:1/159 to All on Wednesday, November 02, 2016 15:21:00
    Hi everyone, seen the issue of telnet attacks mentioned a number of times.

    I use pfsense firewall at home. Easy to install and configure. And with the pfBlockerNG package installed, turned on with a bunch of the normal countries blocked, my attacks have gone down by at least 98%.

    Adding additional blocking lists (ie: Spamhaus) reduced it once again. It's
    on my list of things to do to try to figure out how to incorporate the badip.txt automatically, but for now the "out of the box" configuration has drastically helped. No need to change from port 23 now.

    Just an FYI
    Cheers

    Thanks for this :)

    I went looking to see if I could run it on my Pi but it look like that's a no go :(

    Took a quick look after finding a browser that would work there, It shows AMD and 32bit x86 install only. Most of us are on Linux/Pi including me, can't be used.

    No unfortunately. And I'd strongly recommend intel NIC's as well.

    The system was brought down by an attack this morning via a worm, PDM:Worm.win32. Kaspersky total security detected these, cleaned the files
    and were in quarantine, still I felt it best to restore the entire system
    from the back up on the thumb drive. The worm attempted to delete several key files, mis.exe, nodespy.exe Luckily I am back and running. Something has to be done to stop these attacks, once and for all, they are getting tiring. But that I guess why that is one of the reasons why a backup is recommended.

    It happened again this morning as well (very early in the morning hours) mystic.exe mis.exe nodespy.exe all deleted.
    I followed the same process to restore these files as I did before.
    Followed by a full scan w/ kaspersky.
    apparently there were no other files missing or damaged.

    I have used bad country and modified it include all countries.
    except your country of New Zealand and a few other countries.
    All Asian counties will remain banned.

    still some think they are slick coming through ip addresses which are not listed on the bad country.txt such as ip's not covered within this list such as ip of 1.34.70.132 I think some also mask their IP or even show an IP address
    of which is phony all together.

    So was it reporting the same worm or something new this time?

    Same attack 2 nights in a row, with the same worm, on occasion it is rare
    that I see my mystic configuration menu open, nothing changed within but
    kinda scary. I wish there was a better way to block people trying connect
    here, it is no surpise I see what they are trying to do by trying connect
    here or trying to connect here by running some kind script (shell) so I updated my kaspersky to Total Security 2017 and we will see what happens in the morning.

    Is it possible that the antivirus detected mystic as a worm as a false positive
    and quarantined the files (so they were deleted from where they should be)?

    I don't want you to misunderstand, I am not blaming Mystic at all, just wondering how the worm got in the first place.
    I am concerned that there are individuals who care not and do not appreciate what it is that I am providing here by running a bbs.
    They see an open port and attack it, their actions and motivations or
    anything but good.

    I mean, perhaps there was no worm, but the antivirus thought mystic was a worm,
    so it deleted it.

    Sometimes Anti-Virus software is a little.. overzealous.

    I've had antivirus delete all sorts of things in the past.

    That sounds more feasible. To me, the odds of a worm targetting Mystic is very low. Why would someone bother? There's not that many Mystic BBSs out there, compared to softer and more numberous targets out there, that would be more useful to an attacker.

    Sometimes the cure is worse than the disease. I find a lot of antivirus software falls into that category.

    These people have been busy hitting this open port 23, so far in this session of Mystic that has been running continuously it has blocked 6394 and refused 2381.

    That is less than 10k.
    That is basically nothing. (assumption is that the timeframe is longer than 3 hours)

    I had a script kiddy trying to login my Asterisk with theses accounts
    0000 - 9999 and everything in between, he was "ready" in much less than 1 hour.

    These are all 'scripts' I guess it is just something that has to be allowed
    to be attempted, the whole reason why I run a BBS via telnet is for the users to enjoy and interact with one another via messaging, or read about their favorite pastimes or interests.

    In the old times usually for fame.
    In recent times to create botnets. (and to gain money from that through eg click fraud)

    For both cases Mystic is a very bad target.
    There is only a minimal installed base, and targeting anything else will be much more lucrative for them.
