The only information(not shared though) was when I attempted to use my seed phrase in Electrum to import my Bitcoin which was then classed as a very secure wallet and the only place ever I attempted to use it because back in 2021 thousands of us panicked when we thought blockchain had screwed up.
With importing your seed phrase into electrum, you created the same wallet in electrum, but the fund was still in the wallet generated by blockchain.com and you didn't increase your security.
The right thing to do was to create a new wallet in electrum and send all the fund to that.
If you want your fund to be completely secure in the future, you should create your wallet on an air-gapped device or use a hardware wallet. Take note that any online wallet is prone to hacking.
