I recently discovered that I have been under continuous surveillance for at least two years through malware on my phone.
The attacker has access to virtually all of my accounts, my full identity, and highly sensitive information that could seriously compromise me, both financially and socially.
I still have access to all of my accounts on the compromised device. However, I assume that even if I use a new device to change my passwords and enable or reset 2FA, the attacker could regain access through existing session tokens. I have not tried this yet because I am concerned that I could lock myself out of my accounts.
WhatsApp is also under the attacker’s control. Is there any way to create a new WhatsApp account using my existing phone number that would no longer be under the attacker’s control? More generally, is there a way to permanently lock this person out of all of my accounts? Or would this only be possible by deleting my most important email accounts and starting over?
Could the attacker already know my new phone number as well? If so, how can I protect myself against this and set up a new, secure device?
My phone has not received security updates for quite some time. Is it possible that I am using apps that have already been cloned or compromised, and that the attacker has already altered the account recovery methods?
How likely is it nowadays to receive malware that can be executed in the background through an SMS?
How can I obtain a new phone number as anonymously as possible, so that it cannot be discovered through social engineering or other means?
You may be wondering why the attacker has not already emptied my bank accounts or published sensitive information about me that could cause serious harm. I honestly do not know. I know this person personally, but I have no idea what their intentions are or what they may be planning. This uncertainty is one of the reasons why I am taking the situation very seriously.
I would appreciate any advice or guidance on how to secure my accounts and devices in this situation
