the Website hijacking！

Hello @yourongguan,

Don’t know if you’re a developer. Wordfence is the best way to track malware just scan that and do whatever they asks.

the best way is just to restore the website from your backups (backup from the time when your site wasn’t infected), other than that as the last answer suggested, like wordfence there are many plugins that will scan and remove infection, other than that remove any suspicious plugin or theme and reset your password, If you are not using any reputed hosting then also consider switching.

Please also note the following 2 articles:
