My mobile phone message was inexplicably transferred to a stranger's mobile phone. I didn't set up any SMS forwarding. I hope someone can help me answer it.

This software may be installed on your mobile phone: SMS undercover, also known as SMS master, is a professional Windows Mobile smartphone SMS transmission, automatic backup, real-time monitoring software, and can also be used to prevent the phone from being lost. Similar to incoming call forwarding, it can help you transfer the short message to another mobile phone. You can set whether to forward all the short messages or the short messages of some important contacts, and you can also set whether to delete after forwarding, or to clone only one forwarded message and keep the original short message. This is very meaningful for people who use two mobile phones at the same time.

Check the mobile phone installation file, delete this program and it will not be transmitted again.
