## Introduction
16+
SNOWCRASH creates a script that can be launched on both Linux and Windows machines. Payload selected by the user (in this case combined Bash and Powershell code) is embedded into a single polyglot template, which is platform-agnostic.
17+
18+
There are few payloads available, including command execution, reverse shell establishment, binary execution and some more :>
19+
20+
21+
22+
## Basic usage
23+
24+
1) Install dependencies: `./install.sh`
25+
26+
2) List available payloads: `./snowcrash --list`
27+
28+
3) Generate chosen payload: `./snowcrash --payload memexec --out polyglot_script`
29+
30+
4) Change extension of the polyglot script: `mv polyglot_script polyglot_script.ps1`
31+
32+
5) Execute polyglot script on the target machine
33+
34+
## Additional notes
35+
Delay before script run and payload execution can be specified as an interval (using `--sleep` flag) in the form:
36+
37+
x[s|m|h]
38+
39+
40+
where
41+
42+
```
43+
x = Amount of interval to spend in idle state
44+
s = Seconds
45+
m = Sinutes
46+
h = Hours
47+
```
48+
49+
50+
After generation, the extension of generated script containing the payload can be set either to `.sh` or `.ps1` (depending on the platform we want to target).
51+
52+
53+
54+
Generated payload can be written directly to STDOUT (instead of writing to a file) using `--stdout` flag.
