GO sandbox to run untrusted code.

goBox uses Ptrace to hook into READ syscalls, giving you the option to accept or deny syscalls before they are executed.


Usage of ./gobox:

gobox [FLAGS] command

-h Print Usage.
-n value
A glob pattern for automatically blocking file reads.
-y value
A glob pattern for automatically allowing file reads.

Use cases

You want to install anything

> gobox -n "/etc/password.txt" npm install sketchy-module

BLOCKED READ on /etc/password.txt
> gobox -n "/etc/password.txt" bash <(curl  https://danger.zone/install.sh)

BLOCKED READ on /etc/password.txt

You are interested in what file reads you favourite program makes.
Sure you could use strace, but it references file descriptors goBox makes the this much easier at a glance by printing the absolute path of the fd.

> gobox ls
Wanting to READ /usr/lib/x86_64-linux-gnu/libselinux.so.1 [y/n]

NOTE: It’s definitely a better idea to encrypt all your sensitive data, goBox should probably only be used when that is inconvenient or impractical.
NOTE: I haven’t made any effort for cross-x compatibility so it currently only works on linux. I’d happily accept patches to improve portability.
