KuCoin, a major cryptocurrency exchange based in Singapore, has confirmed a security breach of its ERC20, Ethereum, and Bitcoin hot wallets, with hackers reportedly stealing more than $150 million worth of crypto and transferred funds to an unknown wallet.
This is a basic question but also quite complex. I just saw a recent Tweet by Changpeng Zhao (CZ Binance) about AWS going down and how it impacted Binance. That lead me to realize there are hot wallets on Amazon Web Services with tens of millions of dollars in them, or even more. Let's assume a very, very hardened VPS setup for a moment. AWS. Azure. Digital Ocean. Vultr. Etc. I'm talking updated and regularly patched Linux. Allowing login with only SSH keys + very complex passwords. No root login or access. Whitelisted IP addresses. The whole ordeal, all setup 100% perfect. Is there still exposure by the VPS provider? Like couldn't a rogue Amazon employee access the VPS and somehow image the disk and get access to a hot wallet? At the end of the day, you're storing crypto on someone else's computer. Are all their employees locked out too? I imagine someone would have access. Help me think through the risk here and threat vectors of using a VPS to host a hot wallet. Even when the VPS is 100% solid per all current security practices.
Having a sense of humour in all this fork claiming, is important. Today my Bitcoin Hot wallet finally finished loading after a full month. Add 1.5 more days & my private keys synced .My coins show.Put out the flags and pour a glass of wine OK? Celebrate. Where to deposit?
