#
# Cat-Scale Linux Collection Script
# Version: 1.3.1
# Release Date: 2021-11-30
#
# Latest public release available at https://github.com/FSecureLABS/LinuxCatScale
#
# Instructions:
# 1. Ensure the script is executable, run "chmod +x <script_name>"
# 2. Run with Sudo privileges, "sudo ./<script_name>"
#
# What this script does:
#  - Collects volatile data such as running processes and network connections
#  - Collects system information and configuration
#  - Enumerates and collects persistence data (programs that run either routinely or when the system starts)
#  - Collects log data from /var/log (contains security and application logs)
#  - Creates and records SHA1 cryptographic hashes of binary files
# The script does this by executing local binaries on your system. It does not install or drop any binaries on your system or change configurations. 
# This script may alter forensic artefacts, it is not recommended where evidence preservation is important.

Usage: sudo $0 [ -d OUTDIR ] [ -f OUTFILE ] [ -o OUTROOT ] [ -p OUTFILE_PREFIX ]

 -d	OUTDIR, Optional, Directory where output will be staged while running CatScale. Overwrites default, which is "catscale_out" 
 -f	OUTFILE, Optional, Name of resultant archive file created by CatScale (.tar.gz will be appended by the script). Overwrites default, which has the format of "catscale_<Hostname>-<DateAndTime>"
 -o	OUTROOT, Optional, Root directory/filesystem for output to be saved. Overwrites default, which is set to current directory script is running from, $(pwd). 
 -p	OUTFILE_PREFIX, Optional, Prefix to use for archive file. Overwrites default, which is "catscale_"
