Encrypted wallet, VPN, sandbox, don't use TeamViewer or other cloud services on your staking machine. Common sense, done.
While they all deter a theif anyone determined to get your wallet is going to get around those measures.
Your staking wallet makes you a target and ARCH users are OK with being hacked and will all agree it is the victims fault they lost their investment in Arch.
So best way to become and ARCH CEO is to just steal wallets it seems. ARCH management seems ok with this.
Please just stop this nonsense. It was your own fault for not encrypting your wallet. END OF STORY.
You can't blame it on anyone but yourself. Just take this as a lesson learned.
