You can call it virus ,that's fine , let say its a virus what 'crypto jacking" your miner Wink

Be careful if you have one ASIC " infected " and you have more than one ASIC , within a short period of time all of your ASIC will be a "crypto jacking victim" , or we can say infected with a virus

If there is no signature protection on the firmware you are using, that "virus" simply gets through the ASIC firmware script.

To protect your ASICs from getting infected, install Bitman firmware (released after December 1, 2019) all on your asic you have.
The network device password and ASIC password always must to be different !
If the infected ASIC gets into the network, it will infect the others despite the firewall.

HERE IS some info for you , How to Save your ASICs , if you know how to run some commands

thanks for the advice.... i will keep it in mind and look at the link posted.
at the moment i got only 1 so i guess by getting a new circuit board and changing the passoword ill be fine.
i will let you know and thanks again all of you for the support

if you ever pop by in barcelona let me know and ill take you around Cool

few days ago i got my first new l3+ and stupid me i havent change the passoword so he got hacked....
i try to flash it with an sd card of 16g but nothing happend...at 19.00 my local time take over the miner and change the pool address...
i dont know more what to do...
i download the last l3+ firmaware and flash it.... but maybe i did somethings wrong ....
do the internet cable need to be connected during the flashing??,,,
and after its flash ...
how can i see if he really did it ?

maybe its the sd card Huh

its new...but 2 or 3 times i disconnected just by pulling it out but after i have been format it at 32 fat and place in the file ...
im kind of lost...

Your ASIC is a cryptojacking victim

its not a virus , someone gained access to your miner , and changed some settings there , redirected the hash power to his own account probably

, even they can lock you out from your own miner ....

My suggestion is completely reinstall the Latest offical Bitmain Antminer L3+ software on your asic from SD card

Instruction how to do the firmware reloading from SD card is HERE

After reinstalled the software , make sure you are not using the default login information.
Also... if you have a static ip , try to change that ip somehow ,call your internet provider and ask them to assign a new IP for that location.

thanks for the advice but its a virus as bitmain sad too.....
i try everything... i cant flash it in anyway... i even shorted 2 points on the circuit board begore flashing it....but nothing..
at 19.00 mytime the virus kicks in and the pool addreess are changed..
im buying a new ciruit board....as also bitmain adviced if the shorted process will not work the board need repair.

Try it again from the start redownload the SD card firmware and flash it again.

Check this guide below for the right procedure.

- https://support.bitmain.com/hc/en-us/articles/115000216034-L3-L3-and-L3-Control-Board-Program-Recovery

Sometimes the issue is that the card reader is full of dirt so cleaning them might solve your issue and sometimes the issue is a fake SD card so use authentic SD card and try to flash it again.

its seams its a very nasty virus... i even short out 2 points on the board prior the flashing... and now dosent even turn on both led ligth when is done like before....
bitmain said it too... if the sorting the 2 points dosent work the board need repair....
i already got one form east europe and will be here next week...
i will try a new sd card but seams is like the corona virus of the miner....

I'd suggest going out and buying a new sd card that will fit it and trying to redo it with that - I think it's possible to install antminer firmware from a new sd card just make sure you copy the relevant stuff across from bitmain's support pages.

Otherwise look up how to format the drive via a disk utility on your computer (but you might expose your computer to malware and your own inexperience if you try to do that).
