Heist

Can someone give me hint about privilege escalation?
I found the browser process… (only thing that stands out tbh) looked inside place where it stores data. However didnt find anything useful here except of few empty databases.

Is that browser process used to gain root? Did i miss something inside the place where it stores data?

PS. Some people are trolling this machine, few hours ago the data storage directory had changed permissions, so noone else could access it with user privileges.
