Last week I found out that a lisk address that I had was emptied.
I found out that is was caused by NOT having an outgoing transaction.
I am sure this happened to me. I still can login to the Lisk address and the thief left some marginal funds in there that I tried to send out.
But when I do that the lisk nano wallet complains it cannot send out the funds with the error message:
Invalid sender public key
The problem solution is described here:

https://explorer.lisk.io/address/762745598824670449L is the address of the hacker
If you look into the adresses that have send LISK to the hacker address you will see that all 4 funders there was no outgoing transaction before the hacker stole the funds.
Only one of the adresses is mine. The other 3 are from people I don't know.
My LISK was hacked around beginning of december. The security blog that I mentioned was written on 21 dec 2017.....
