Slow fog cosine: CoinStats wallet private key leaked on a large scale but with limited proportion, awaiting official disclosure of details.

ChainCatcher message, Slow Mist founder Yu Xian posted on social media regarding the attack on CoinStats, stating: "I used this app quite a while ago; it's convenient for checking the asset status of target wallets. There are quite a few applications like this, so I won't name them. Some have their own wallet functions (which is a risky area), allowing users to create wallets and use them subsequently. I'm quite curious about how CoinStats Wallet, which is supposed to be user self-custodied, had its private keys leaked on such a large scale; the official statement is that it's 1.3%.

This kind of large-scale leak, with a limited proportion, can be speculated upon, but I won't discuss it here. Let's wait for the official disclosure of details."
