OKX Web3 Security Team: Protecting Private Keys Like Protecting Eyes

Not Your Keys, Not Your Coins - Decentralized freedom at the cost of absolute 'private key security'. The OKX Web3 security team hopes to strengthen everyone's awareness of private key security through this science popularization, while once again sorting out the most easily overlooked security blind spots. Why are private keys or mnemonics leaked If you download and use the official version of a big brand wallet through legitimate channels, the private key will generally not be leaked during normal use. Private key leaks are mostly caused by improper storage and being obtained by others. Once someone has access to your private key, they can import and control the assets of that account in any wallet. Why is there very little that wallet manufacturers can do once the private key is leaked Firstly, we will assist users in investigating the flow of funds and analyzing whether on chain funds may be related to known hacker groups or address clusters. At the same time, users will be advised to transfer their assets that have not yet been stolen as soon as possible to reduce the risk of further losses. For cases where the stolen amount is significant, we recommend that users promptly contact the local police and seek assistance through judicial channels. The internal team will also conduct in-depth analysis of the incident, summarize the hacker's modus operandi, and provide reference for subsequent user protection. As a tool provider, the wallet itself cannot and does not have the authority to freeze or roll back on chain assets. Once the private key is obtained by a hacker, the other party usually completes the fund transfer within seconds through automated scripts, which are extremely fast and difficult to intervene in. Only when the stolen funds ultimately flow into a centralized exchange, can a temporary freeze be applied for through judicial means. When there is a connection between the funding chain and the hacker cluster we have already mastered, we will start from their common modus operandi to assist users in recalling whether they have carried out certain high-risk operations recently, and then determine where the private key may have been exposed.
