And the possibility of mining KawPow 

I tried to use the -clKernel 3 (Phoenix 5.7b) option for various drivers from 18.6.1 to 21 .... but on each of these drivers -clKernel 3 is ignored for all GPU (RX580 Nitro + 8GB Micron cards)

I did all the updates of Ledger Nano S only with the Ledger Live application. I don't even read or use any SMS, e-mails or links offering updates for any computer hardware.

I never store any passphrases for Ledger on my PC.

I have traded with Ledger many times and always carefully. It was probably some hacking attack on my PC, unknown to me. I thought Ledger was safe ...

Hello
386.5 ETH was stolen from my Ledger Nano S
8 days ago(Dec-08-2020 01:16:28 PM +UTC) During the transaction of sending 0.17 ETH to the Bitbay exchange account via Ledger Live, it soon turned out that instead of the declared value, the entire cryptocurrency disappeared from my account and was sent to the hacker account 0x453E0c72664AcE9531b995a23b956873D7C777f8.
Today, a few hours ago(Dec-17-2020 02:57:27 AM +UTC) all my cryptocurrency has been transferred to another hacking account again - 0xdA84772B737939Df44367e57D40069801CA5b7F8
I lost all cryptocurrency from my account even though all transaction procedures were shown in the Ledger Live app and hardware wallet display as correct. I have no idea how it could have happened and I lost all hope of recovering the stolen cryptocurrency. I wanted to warn all Ledger owners about the possibility of losing their cryptocurrencies.
