Last year, my friend who is learning hacking for nearly 3 years hacked my phone using social engineering by installing some malware in my phone. (After researching on Google, I think it might be a reverse meterpreter)
As soon as I realized that my phone has infected after one hour since malware was installed, I scanned my phone with Avast anti-virus program and found that malware and deleted it.
After about one month, some strange things were happened without my knowledge. First of all, there was a message which I didn't send in my phone. The contents of the message contained some codes. After I saw it, I reset my phone immediately. Second thing is that some of my messages in Messenger were automatically seen even before I didn't read them. I checked the devices from Where You're Logged In in Facebook Settings but there were no unknown devices listed there. Two-Factor Authentication is turned on. So I presume my Facebook account is not hacked. (I already have some security knowledge and I haven't never clicked any suspicious links yet). I think it happened from my phone. There were also some strange things.
- The question is how can I know that my phone is hacked? How do I know if it has backdoors?
Btw my phone is running android 11. I wanna ask this because even I reset my phone and scanned with anti-virus programs (for social accounts I changed passwords), messages on Messenger were still seen automatically and sometimes some apps are automatically closed like camera app when I am taking photos with tripod.
After my phone was hacked by my friend (I deleted that malware), can he still hack my phone? Did he know my MAC or IP addresses?
The last question is once my phone is hacked, can malware spread thru WiFi and infect other devices? (In my case it is a Windows 10 laptop)
