NAME
nepenthes - finest collection -SYNOPSIS
nepenthes [OPTIONS]- nepenthes [OPTIONS] [PATH]
DESCRIPTION
By emulating widespread vulnerabilities Nepenthes is able to catch and store worms using these vulnerabilities. Furthermore you are able to determine the malware activity on a network by deploying a nepenthes sensor. The programm emulates different well known vulnerabilities waiting for malicious connections trying to exploit these. If a connection tries to exploit something, nepenthes tries to guess which exploit is going to be used. There are several different ways a exploitation can happen, the attacker can ask nepenthes to:- •
- connect a provided ip & port offering a shell there (connectback)
- •
- bind a shell on a port (bindshell)
- •
- direct execute a shellcommand
- •
- provide a url from where to download a file and execute the file
- •
- use specific filetransferr mechanisms to transferr the file (link, blink, mydoom ...)
If a shell is expected, bindshell or connectback shell, nepenthes will offer this shell to the attacker and fullfill the requested actions. In most cases there are two ways worms try to spread themselves using a shell,
- •
- tftp - trivial filetransfer protocoll using tftp.exe in Microsoft Windows.
- •
- ftp - filetransfer protocoll using ftp.exe in Microsoft Windows.
Nepenthes will parse the shell instructions and try to download the file, upon success the file will be stored.
OPTIONS
- -c PATH, --config=PATH
- PATH to nepenthes.conf
- -d PATTERN, --disk-log=PATTERN
- apply filter to console logging. PATTERN can consist of crit, warn, info, debug and spam, combine tags using , .
- -f OPTIONS PATH, --file-check=OPTIONS PATH
- Use Nepenthes to check if a file or a directory of files in PATH contain known shellcodes. PATH can be a directory or multiple files. OPTIONS can be rmknown,rmnonop,nothing.
- -h, --help
- show help
- -H, --large-help
- show help with default values
- -i, --info
- how to contact us
- -k, --check-config
- check nepenthes.conf config for syntax errors
- -l PATTERN, --log=PATTERN
- apply filter to console logging. PATTERN can consist of crit, warn, info, debug and spam, combine tags using , .
- -L, --logging-help
- display help for -d and -l
- -o, --no-color
- log without colors to console (does not work yet).
- -r PATH, --chroot=PATH
- chroot to PATH
- -R, --ringlog
- use ringlogger instead of filelogger
- -u USER, --user=USER
- switch the user the process runs as USER must be a users name.
- -g GROUP, --group=GROUP
- switch process group GROUP must be a groups name.
- -v, --version
- show version
- -w, --workingdir
- where shall the process live
EXAMPLES
- nepenthes -d crit,warn,info
- start nepenthes and log only messaged with loglevel critical, warning and info to disk
- nepenthes -u marshall -g mother
- start nepenthes and change to user marshall and group mother.
- nepenthes -r /opt/nepenthes
- start nepenthes and chroot to /opt/nepenthes
- nepenthes -u marshall -g mother -r /opt/nepenthes
- start nepenthes and change to user marshall and group mother and chroot to /opt/nepenthes
- nepenthes -f rmknown,rmnonop,dononp /opt/nepenthes/var/hexdumps/
- check the directory /opt/nepenthes/var/hexdumps for known shellcodes, remove known shellcodes, remove shellcodes without nop slide, check shellcodes without nopslide.
- nepenthes -f nothing /tmp/*.bin /tmp/unknown_shellcodes/
- check the files in the directory /opt/nepenthes/var/hexdumps and the files in /tmp/*.bin for known shellcodes, do nothing.
