I created a multi sig wallet using Electrum in 2023
It was a 2 of 3 wallet. Meaning it would need signed transactions from 2 wallets to move the Bitcoin

But in February 12, my computer got hacked. And Bitcoin of some of my wallets got moved somewhere

Don't understand how it was possible

The 3 wallets that were signatories to that multi sig was not hacked. As in no crypto were lost on those wallets

Here is the my Bitcoin address
bc1qcuevd4xqrqdhxwde83m6tp4hn25lsedq27vk43l7ycklnk2lhytq56mr3t

This is the txid

Could the multi sig wallet be hacked without hacking the 3 wallets used to sign ?

BTW, one of the wallets was a Ledger
