NAME
neopi - web shell code detection
SYNOPSIS
neopi [options] <dir> [regex]
DESCRIPTION
This manual page documents briefly the neopi command.
neopi is a Python script that uses a variety of statistical methods to detect obfuscated and encrypted
content within text/script files.
The intended purpose of NeoPI is to aid in the detection of hidden web shell code.
The development focus of NeoPI was creating a tool that could be used in conjunction with other
established detection methods such as Linux Malware Detect or traditional signature/keyword based
searches.
NeoPI recursively scans through the file system from a base directory and will rank files based on the
results of a number of tests.
It also presents a “general” score derived from file rankings within the individual tests.
OPTIONST
The program follows the usual GNU command line syntax, with long options starting with two dashes (`-').
A summary of options is included below.
-v, --version
Show version of program.
-h, --help
Show summary of options.
-C FILECSV, --csv=FILECSV
Generates a CSV output to FILECSV containing the results of the scan.
-a, --all
Run all tests including entropy, longest word, and index of coincidence. This is the recommended
way of running neopi.
-e, --entropy
Run only the entropy test.
-l, --longestword
Run only the longestword test.
-c, --ic
Run only the Index Coincidence test.
-A, --auto
This flag runs an auto generated regular expression that contains many common web application file
extensions.
This list is by no means comprehensive but does include a good ‘best effort’ scan if you are
unsure of what web application languages your server is running.
Current list of included extensions: php, asp, aspx, sh, bash, zsh, csh, tsch, pl, py, txt, cgi,
cfm
EXAMPLES
