In this article, we’ve outlined three strategies for protecting Bitmain Antminer L3 miners from viruses, malware, and remote attacks.
Recently, some customers claimed that malicious attacks had infiltrated their Bitmain Antminer L3+ and Antminer L3++ mining farms. The majority of them noticed that their mining pool worker names had been changed and that their miners had been used in other pools they had not joined, which had led to a loss of profitability.
Customers visiting malicious websites and downloading malicious software that could load itself and infect the Bitmain Antminer L3+/L3++ miners caused this to occur.
In light of this, we are providing some advice on how to combat and eliminate (if you are unfortunate enough to be affected by) such threats.

Three Ways to Prevent
1. Visit no websites that might be risky or suspicious.
2. Avoid downloading or utilizing firmware that is not offered by Bitmain, particularly firmware that promises to help you overclock your S9 or T9 series miners.
- We would like emphasize that overclocking your miners or using any unauthorized firmware resulting Bitmain Antminer L3+/L3++ miners malfunction will void your warranty immediately
3. Change your password and keep it safe. The best form of protection is always a strong password.
Three Steps to Handle and Eliminate
The three steps to handle and get rid of the virus on a Bitmain Antminer L3+/L3++ are listed below.
1. Quarantine Your Network (IMPORTANT!)
Determine the affected PC or miners if you have detected a threat.
How does a Bitmain Antminer L3+/L3++ miner that has been infected behave? Your wallet will be taken over, coins will be taken from it, etc. You will discover that your miner is actually mining for a secret pool—a pool you did not join…
To find out which of your computers or miners have a virus infection, check all of your computers and miners. Then, by placing the infected individuals in quarantine, stop the virus from spreading throughout the network.
It is critical that you remove the compromised PC or miner from the network or add it to a “quarantine network.” Otherwise, the virus will spread by infecting additional computers connected to the network.
●Unharmed miners were separated from infection hotspots and observation areas.
●Use the default settings on the primary routers; there is no need to send traffic to the secondary routers.
The WL AN port of the first quarantine routers should be connected to the main router.
●Then connect the LAN ports of the switches in the second quarantine to the router in the fifteenth quarantine.
Sources of the IP include the routers placed in the initial quarantine.
2. Reset to Factory Settings
To learn more about how to restore your infected miners’ factory settings, please refer to the page below.

A SD card can be used to update the miner’s firmware and restore it to its factory default settings.
3. Change Your Password
Change the miner’s password to one that is strong and secure right away after you reset your Bitmain Antminer L3+/L3++ miner.
Go to your miner User Interface > System > Administration.
In case you are not aware, the default password for our new or reset miner is “root”.
Once you see the status is “Updating Password”, it means your new password works like a charm. Additionally, keep in mind that if you forget your password, you will be unable to reset it or change it.
How can I change the passwords of several miners at once?
We recognize you may own tens or even hundreds of miners rather than just one. Use the APminerTool (V1.0.7) to change the passwords of all of your miners at once!
Search for the Bitmain Antminer L3+/L3++ miners you would like to change, select all of them and choose “Change Password”.
