James Gillard, a Bitcoin core developer, software vulnerability for Ant15er S15 devices, which in theory allows the assailants to completely control the ASIC. At the same time, the developer is convinced that this is not the only version of Bitmain software that is vulnerable.

So, a Twitter user under the nickname @00whiterabbit simulation and assault, which allowed it to replace the payment address, delete the device, and even replace the software completely. Despite the fact that a hacker needs to go through a firewall, the risk of assault on S15 devices exists, Bitcoin Magazine reports, stating Gillard.
It is worth noting that the developer is ready to provide information to Bitmain for the vulnerability unless the company opens the code of its software released under the GNU GPL license. Gillard is convinced that the giant mining violates the license license by hiding the code by users.
00whiterabbit added that it does not take advantage of the intention to avoid user authentication. Its aim, he emphasized, is to return the management of the software directly to the miners.
For everyone who follows: WE DO NOT DESIGN this to avoid user authentication,

Recall that Bitmain has introduced models S15 and T15 based on 7-nanometer chips BM1391 last November. Their price was $ 1,475 and $ 913, respectively.
In September 2018, Braiins Systems introduced software for open source ASIC miners based on the Linux family of operating systems – OS Brains or BOS. The company's blog then published information about Antwered backdoor, which allegedly allowed Bitmain to take control over Antimer devices.
