Antminer security firmware description
Necessary: To avoid being poisoned by the miner, please do not download third-party firmware from unknown sources!
What is secure firmware?
The security firmware is firmware released by Bitmain to protect the interests of Antminer users. The secure firmware has all the functions of the previous firmware version. In addition, turning off SSH can effectively prevent the intrusion of other illegal miners and block the channel of virus transmission and infection so that your mining is not affected.
In the official website firmware, how to determine which one belongs to the secure firmware?
It can be judged from three aspects:
1) There will be instructions in the firmware description on the official website, for example:
2) The name of the secure firmware file ends with sig.
3) After installing the security firmware, the miner cannot log in using SSH.
What are the functions of secure firmware?
The firmware signs the function of the secure firmware, and the SSH service is disabled. Therefore, the most significant difference compared to stock firmware is that the SSH service cannot be used.
Why can't I SSH into the miner?
Because the secure firmware has disabled the SSH service.
When the firmware is refreshed, the subtitle "System Upgrade Failed-Cannot Find Signature!!!" pops up. What does it mean?
It means that the firmware to be updated is not secure.
How to flashback to the previous version of the firmware?
Please support the latest official firmware because the latest firmware is the most comprehensive and optimized firmware, and the official does not support flashing back to the old firmware.
Which models apply to secure firmware?
The official website currently has secure firmware for Antminer S17, T17, S17Pro, S15, T15, S9, S9I, S9J, L3+, DR5, Z11.
For more new security firmware, please follow the official website of Bitmain.

The next time I read a blog, I hope that it doesnt disappoint me as much as this one. I mean, I know it was my choice to read, but I actually thought you have something interesting to say. All I hear is a bunch of whining about something that you could fix if you werent too busy looking for attention.        Trade Command Center
