S9 firmware issue

[fiucsavar]

I have ordered a 3 new motherboards for my S9 antminers and they worked just fine for a while, but around a day ago they have started to mine to a different address than mine. The address is: 3CJgXokLQrRCQcEoftS7MbPDSXhXpX6P55.

And it my miner status page looks like this: https://imgur.com/a/QyNOIjf.

I did a google search of course,and I've found that this supposed to be some kind special software and it includes a developer fee as well. I would accept the dev fee if it was reasonable even if i have never wanted to use this firmware but it goes on my other miner for over 12 hours.

I'd like to get rid of it as soon as possible. I don't want to use other people work for free,and i would like to not mine for another individual either.
Reinstalling a genuine firmware only seems to solve the problem temporarily.

Any help would be appreciated.

Where did you get your control boards from?  It may be that your control boards have firmware that is either hacked or has a dev fee.  I think there is a technique to reset the firmware or you can try loading BraiinsOS via the SD card.  You’ll need to move the jumper at JP4 to startup from the SD card. Take a look at the following website to get started.
https://docs.braiins-os.org/

Also, read the forum at this link and see if that helps

Where did you get the firmware from? Are you using firmware which is posted by newbies in mining software section? Because of them has backdoor or they are stealng hashrate from your miner.

So I suggest the only solution for this is to flash it with "Antminer-S9-all-201711171757-autofreq-user-Update2UBI-NF.tar.gz". Then after successfully flash it through web GUI perform a hard reset by holding IPreporter/Reset button for 15 to 20 seconds until the miner reboot.

If you receive error when flash the miner through webGUI flash it with SD card I suggest follow the method from here S9 series (S9, S9i, S9j, S9 Hydro) Control Board Program Recovery. Then flash again through webGUI follow the suggested firmware above and don't forget to do a hard reset.

Definitely go install Braiins OS, its going to wipe whatever thrash has gotten in there, and while you are at it, make sure to set up proper passwords just in case.

This is a virus, I've seen it on machines I've worked with, mining to the exact same address.

With Antminer S9 you can sometimes do an IP Report reset and then flash one of the new official firmwares right away. Otherwise you'll want to install good firmware from an SD card, or get new control boards.

You need to make sure that you've changed all of your SSH passwords, or are using a firmware that disables SSH access.

When you SSH to a miner, you can use the passwd command to change the password, and then run cp /etc/shadow /config/shadow to apply the change (otherwise the password will revert when the miner is rebooted).

You can see that the authors of this malware are currently receiving 0.8 BTC ($7000) per day: https://www.nicehash.com/miner/3CJgXokLQrRCQcEoftS7MbPDSXhXpX6P55.

It is exactly what tim-bc described it as, however you most likely won't have to go to the extend of getting another control board, just flash an official firmware or braiins using an SD card and your problem should be solved, in some cases even a normal reset can fix the issue, you should be careful from the vendor who sold you those control boards, and just in case they are not aware of it , they need to have the issue fixed ( the last part is based on the assumption that the control boards you bought came with this malware which is usually the case, they sell for cheap and that's how they get so many people to buy them).

P.S , do something about your miner's temp, the first board is going to be fried - if the sensor is reporting the actual temp.
