Coinbase executive: '14 year dormant whale $8 billion BTC transfer' may involve private key leak

According to Golden Finance, Coinbase director Conor Grogan posted on social media that there is a possibility of private key theft or leakage in yesterday's "14 year dormant Bitcoin ancient whale $8 billion BTC transfer". Conor discovered that one hour before the large-scale transfer of BTC assets in the Whale Wallet, one wallet conducted a test transaction for Bitcoin Cash (BCH) and immediately transferred all BCH. Conor believes that this behavior pattern is unusual, as other BCH wallets have not been used, and BCH is usually less monitored by the Whale monitoring service, possibly as a low-key way to test private keys. He speculates that these wallets are unlikely to be exchange wallets. Conor stated that although this is only speculation, if true, it could be the largest digital asset theft case in human history.
