My first time playing DMZ

My friend invited me to play DMZ, but I didn’t have it installed, so I had to wait a bit.

After it got done, I decided to play solo and just test things out by myself. I got some awesome loot! A few broken glasses, some gold bars and a Large Backpack - But I ran into hackers and died. Are there spots where I can’t run into hackers? Is Ashika Island just a bad spot? Give me some tips.
