user128440: Weird... I took out a small amount of BTC from Coinbase Pro, generated a new receiving address in Electrum, and as soon as the transaction came in, the BTC was transferred to an address which I do not control...
Here is the withdrawal transaction:
63b1674c7f62e6c33d342518cc580b86de90ed4f1b77c67c76d1cb80cafe47a6
And here the one that sent the BTC out:
dd7660c0cc1e19f2e42faad42ca4ee8e92a7dc15da083a5277ff33b9a1badaeb
I really do not understand, I have also imported the receiving address into bitcoind, which is still syncing.
Any help would be highly appreciated.

user128356: I can't answer on the why and the how, but when you focus on the receiving address (1CfaunqrVpcXmpLheUVWeSP1KPsKDha1Nb), there is some weird things.

You can find it in some presentation about "what blockchain is?" > What is blockchain

You can also find it on some powerpoint presentation about "Blockchains transforming the domain industry" where you can see that typing some domain name can route a payment to an address (this one was taken as example). Unstoppable Domains


This address is often used as an example in websites and presentations.
Is there any chance it was on your clipboard, following a copy from.. somewhere?
You can search it on a random search engine to see by yourself.
