Preventing and Removing Viruses, Malware, and Remote Attacks on ANTMINER

Start with safety and logs

Power down before opening a miner, label cables before moving boards, and capture logs before repeated reboots erase useful evidence. Record model, firmware, pool, uptime, fan speed, temperature, reject rate, chain count, and the exact error text.

Confirm the fault class

Separate configuration faults from hardware faults first. Pool errors, DNS failures, bad worker names, overheating, weak power, fan faults, and missing hashboards can look similar from the dashboard but require different fixes.

Document the test path

Change one variable at a time and keep the before/after result. Note cable swaps, PSU swaps, firmware changes, pool changes, fan replacements, ambient temperature, and whether the fault follows a hashboard, control board, network, or power source.

When to escalate

Escalate to professional repair when there is a burned smell, melted connector, breaker trip, corrosion, repeated hashboard loss, liquid exposure, or a board-level fault that returns after a basic cable, power, firmware, and airflow check.

After the fix

Run the miner long enough to confirm stable accepted hashrate, fan behavior, chip temperature, reject rate, and pool-side reporting. A dashboard that looks normal for five minutes is not enough evidence for a recurring power, heat, or hashboard fault.

ANTMINER Antivirus Software Video Tutorial: Link

We have received reports from customers about malicious attacks on their mining farms. Typically, these attacks involve tampering with mining pool worker names and misuse of miners in other pools, leading to loss of profitability.

Such attacks often occur when customers visit malicious websites and download harmful applications that infect the miners.

In response, we have some recommendations to protect your mining operations from such threats and remove them if needed.

Three Ways to Prevent:

  1. Avoid Suspicious Websites: Do not visit potentially suspicious, unsafe websites.
  2. Authorized Firmware Only: Do not download or use any firmware not provided by BITMAIN, especially firmware claiming to overclock your S9 or T9 series miners. Unauthorized firmware or overclocking can void your warranty immediately.
  3. Strong Passwords: Change your password, and remember it. A strong password is always your first line of defense.

Three Steps to Handle and Eliminate:

  1. Quarantine Your Network: If you detect a threat, identify the infected PC or miners. Infected miners might be mining for an unknown pool or have their wallets hijacked. Quarantine the infected devices to prevent the virus from spreading.
  2. Reset to Factory Settings: Reset your infected miners to factory settings. You can refer to our guide on how to reset miners or use an SD card to reset your miner and install the latest firmware.

  3. Change Your Password: After resetting, immediately change the miner’s password to a strong and secure one. Go to your miner User Interface > System > Administration. The default password for our new or reset miner is “root”. Once the status is “Updating Password”, your new password is set. Remember your password because you cannot reset or change your password if you do not remember it.

If you have multiple miners and need to change passwords in batch, you can use our APminerTool (V1.0.7). The APminerTool, developed by our Antpool team for our ANTMINER, allows you to change the password for multiple miners at once.
