OKX account was stolen for 5 million, and no one noticed it within 15 minutes. Today, it was reported that tens of millions of ETH were stolen again.

After Binance, OK also had users report that their assets were stolen.

A lifetime of knowledge was stolen in just 15 minutes! Be sure to protect your account security. If you have a Google Authenticator, you must bind it. It is best to isolate the network. Although I don’t know if it can be prevented, it is always good to have an extra security barrier.

Small retail investors will not be the primary target. The attacks are basically accounts with more than one million. If necessary, you still need to diversify the risks.

For example, assets can be dispersed across multiple exchanges, or transferred to cold wallets, and then returned after the incident has subsided. After all, a gentleman does not stand under a dangerous wall. The FTX incident that year is also vivid.

So far, I have seen 3 cases of large-scale stolen funds within 1 hour, and the victims were unaware of the whole process!

Apple devices are not absolutely safe either.

Here are some security suggestions:

1. The API function is basically only used when we accept real-time demonstrations or professional traders operate and follow orders. Ordinary retail investors will never use this function. If you see an API that you did not open in your API options, please remember to close it immediately.

2. Exchange account security enablement, two-factor authentication (2FA): Regardless of whether you use any exchange such as OKX, Binance, Bitget, Gate, etc., it is recommended to enable 2FA.

Save the key offline: Do not save the authentication key online, copy it in a notebook and keep it properly, and do not back it up on electronic devices.

Google Authenticator: Check whether the verification code is synchronized to the Google account. It is recommended to cancel the cloud synchronization and reset it.

3. Check the activity of the device regularly, check the "Exchange Device Management" regularly, and remove unused devices to prevent abnormal activities.

4. Manage the withdrawal whitelist

Apple users: You can set a "pass key" instead of the exchange withdrawal whitelist, and perform face verification every time you withdraw money to the Web3 wallet.

Finally, do not download suspicious software on your mobile phone, do not use free WiFi, and do not lend it to others to ensure the safety of your equipment and assets.
