Can android mobile hotspot be attacked

After allowing the use of my android 8.1 hotspot for people that I know steal identities and financial information I notice phone configuration changes. Such as USB configuration being set to MTP or PTP when it was originally set to CHARGING. Unless I clear data for MTP HOST I cannot reset it to CHARGING. Also I notice that my phone will not charge at fast rates. Lastly, after allowing the use of my hotspot I believe my cell connects to rouge base stations and WIFI calling turns on and the version number of some applications change. I also see that applications without names are connecting to the internet. The only way I have been able to return my phone back to its normal function is by doing a factory reset and reinstalling my apps. I am certain my phone is being attacked through its hotspot. I also notice all these same issues after connecting to some WiFi hotspolts. How are my hotspot and WiFi connection being attacked? How to I allow the use of my hotspot and prevent the attacks? Howdo I safely use WiFi hotspots.

Thanks. We'll let you know when a new response is added.

If your statement is true that you let friends use you hot spot to “Steal identities and financial information”. Ask them to fix the problem.. One of them most likely has the skills and did it. They may be preventing you from doing it again as have gone to the law enforcement authorities.

    First of all change all passwords including email account with complex ones. Next observe what happened? If the same will happen, you may stop using mobile for few days, if possible.

    Be cautious when you use free wifi. Don't use & try to connect any unknown wifi even it does not ask for password. It does not mean you can connect any wifi even it asks for password. Also don't provide any personal information when any network asks for.

    Maybe my description was unclear. I did not allow them to use my hotspot to steal identities or do anything illegal. They told me their phone had been cut off due to non payment and asked to use my hotspot for normal internet surfing activity (or so I thought). Seeing they are my friends (at least I thought so) I didn't imagine they would attempt to hack me. Actually, I had no knowledge about how they did their identity theft (I am not involved in that in any way). I assumed they stole or duplicated credit cards.

    And no, I would not ask them to fix my phone. I no longer trust them to have any contact with or access to my phone.

    You have written a good information. But have you changed all of your necessary passwords? That you did not mention. Change all necessary passwords with complex ones. And also if possible do not use phone for few days. Also first of all take backup of your phone with all necessary files/ folders including social media chat etc.

    To be totally clear you're saying you suspect your friends are using your phone as a proxy for illegal activities? Have you tried contacting local law enforcement? If your friends won't immediately stop their activities you need to turn them in, or else you'll also be part of it.

    As well as contact to the local law enforcement, it is also good for contacting your internet provider. They have admin rights & can monitor every activities. This can be helpful also.
