I have never lost my funds from any wallet that I wrote down it's recovery seeds with my hand, it's always those that I type using a keyboard, or trying to import wallet into another wallet.
Actually, it doesn't really matter whether you back up your seed by writing it down on a peace of paper or save it digitally if the device you used to create the wallet is already compromised and connected to the Internet.
What you need to keep your coins safe against malware and cyber attacks is a cold wallet where your seeds/private keys will never be exposed to the Internet.
the moment you type your recovery seed while connect online makes your wallet weak, I am sticking with writing down with a pen and I think you should too.
Even if you type your keys when you are not connected, the key logger can capture them and the moment you go online it will send them to the hacker.
