Unfortunately, previous weeks were too stressful for me, and I didnt even think about my protocol. I cannot prove it's the wifi but today I realised this :
My laptop must have a malware, I tried to move all of my other funds from the ledger to exchanges until I sort my computer and my ledger out. I tried to copy an 0x hex address from the exchange, and when I pasted it, it was a different address!!!!
This is the transaction where my ledger funds were transferred to another address :
