First, a couple of useful oneliners ;)
wget "https://github.com/diego-treitos/linux-smart-enumeration/releases/latest/download/lse.sh" -O lse.sh;chmod 700 lse.sh
curl "https://github.com/diego-treitos/linux-smart-enumeration/releases/latest/download/lse.sh" -Lo lse.sh;chmod 700 lse.sh
Note that since version 2.10
you can serve the script to other hosts with the -S
flag!
Linux enumeration tools for pentesting and CTFs
This project was inspired by https://github.com/rebootuser/LinEnum and uses many of its tests.
Unlike LinEnum, lse
tries to gradualy expose the information depending on its importance from a privesc point of view.
This shell script will show relevant information about the security of the local Linux system, helping to escalate privileges.
From version 2.0 it is mostly POSIX compliant and tested with shellcheck
and posh
.
It can also monitor processes to discover recurrent program executions. It monitors while it is executing all the other tests so you save some time. By default it monitors during 1 minute but you can choose the watch time with the -p
parameter.
It has 3 levels of verbosity so you can control how much information you see.
In the default level you should see the highly important security flaws in the system. The level 1
(./lse.sh -l1
) shows interesting information that should help you to privesc. The level 2
(./lse.sh -l2
) will just dump all the information it gathers about the system.
By default it will ask you some questions: mainly the current user password (if you know it ;) so it can do some additional tests.
The idea is to get the information gradually.
First you should execute it just like ./lse.sh
. If you see some green yes!
, you probably have already some good stuff to work with.
If not, you should try the level 1
verbosity with ./lse.sh -l1
and you will see some more information that can be interesting.
If that does not help, level 2
will just dump everything you can gather about the service using ./lse.sh -l2
. In this case you might find useful to use ./lse.sh -l2 | less -r
.
You can also select what tests to execute by passing the -s
parameter. With it you can select specific tests or sections to be executed. For example ./lse.sh -l2 -s usr010,net,pro
will execute the test usr010
and all the tests in the sections net
and pro
.
Use: ./lse.sh [options]
OPTIONS
-c Disable color
-i Non interactive mode
-h This help
-l LEVEL Output verbosity level
0: Show highly important results. (default)
1: Show interesting results.
2: Show all gathered information.
-s SELECTION Comma separated list of sections or tests to run. Available
sections:
usr: User related tests.
sud: Sudo related tests.
fst: File system related tests.
sys: System related tests.
sec: Security measures related tests.
ret: Recurren tasks (cron, timers) related tests.
net: Network related tests.
srv: Services related tests.
pro: Processes related tests.
sof: Software related tests.
ctn: Container (docker, lxc) related tests.
cve: CVE related tests.
Specific tests can be used with their IDs (i.e.: usr020,sud)
-e PATHS Comma separated list of paths to exclude. This allows you
to do faster scans at the cost of completeness
-p SECONDS Time that the process monitor will spend watching for
processes. A value of 0 will disable any watch (default: 60)
-S Serve the lse.sh script in this host so it can be retrieved
from a remote host.

Β DataSurgeon (ds) is a versatile tool designed for incident response, penetration testing, and CTF challenges. It allows for the extraction of various types of sensitive information including emails, phone numbers, hashes, credit cards, URLs, IP addresses, MAC addresses, SRV DNS records and a lot more!
Please read the contributing guidelines here
wget -O - https://raw.githubusercontent.com/Drew-Alleman/DataSurgeon/main/install/install.sh | bash
Enter the line below in an elevated powershell window.
IEX (New-Object Net.WebClient).DownloadString("https://raw.githubusercontent.com/Drew-Alleman/DataSurgeon/main/install/install.ps1")
Relaunch your terminal and you will be able to use ds
from the command line.
curl --proto '=https' --tlsv1.2 -sSf https://raw.githubusercontent.com/Drew-Alleman/DataSurgeon/main/install/install.sh | sh
Here I use wget
to make a request to stackoverflow then I forward the body text to ds
. The -F
option will list all files found. --clean
is used to remove any extra text that might have been returned (such as extra html). Then the result of is sent to uniq
which removes any non unique files found.
wget -qO - https://www.stackoverflow.com | ds -F --clean | uniq
Here I am pulling all mac addresses found in autodeauth's log file using the -m
query. The --hide
option will hide the identifer string infront of the results. In this case 'mac_address: ' is hidden from the output. The -T
option is used to check the same line multiple times for matches. Normallly when a match is found the tool moves on to the next line rather then checking again.
$ ./ds -m -T --hide -f /var/log/autodeauth/log
2023-02-26 00:28:19 - Sending 500 deauth frames to network: BC:2E:48:E5:DE:FF -- PrivateNetwork
2023-02-26 00:35:22 - Sending 500 deauth frames to network: 90:58:51:1C:C9:E1 -- TestNet
The line below will will read all files in the current directory recursively. The -D
option is used to display the filename (-f is required for the filename to display) and -e used to search for emails.
$ find . -type f -exec ds -f {} -CDe \;
When no specific query is provided, ds
will search through all possible types of data, which is SIGNIFICANTLY slower than using individual queries. The slowest query is --files
. Its also slightly faster to use cat
to pipe the data to ds
.
Below is the elapsed time when processing a 5GB test file generated by ds-test. Each test was ran 3 times and the average time was recorded.

Dismember is a command-line toolkit for Linux that can be used to scan the memory of all processes (or particular ones) for common secrets and custom regular expressions, among other things.
It will eventually become a full /proc
toolkit.
Using the grep
command, it can match a regular expression across all memory for all (accessible) processes. This could be used to find sensitive data in memory, identify a process by something included in its memory, or to interrogate a processes' memory for interesting information.
There are many built-in patterns included via the scan
command, which effectively works as a secret scanner against the memory on your machine.
Dismember can be used to search memory of all processes it has access to, so running it as root is the most effective method.
Commands are also included to list processes, explore process status and related information, draw process trees, and more...
Command | Description |
---|---|
grep | Search process memory for a given string or regex |
scan | Search process memory for a set of predefined secret patterns |
Command | Description |
---|---|
files | Show a list of files being accessed by a process |
find | Find a PID given a process name. If multiple processes match, the first one is returned. |
info | Show information about a process |
kernel | Show information about the kernel |
kill | Kill a process (or processes) using SIGKILL |
list | List all processes currently available on the system |
resume | Resume a suspended process using SIGCONT |
suspend | Suspend a process using SIGSTOP (use 'dismember resume' to leave suspension) |
tree | Show a tree diagram of a process and all children (defaults to PID 1). |
Grab a binary from the latest release and add it to your path.
# search memory owned by process 1234
dismember grep -p 1234 'the password is .*'
# search memory owned by processes named "nginx" for a login form submission
dismember grep -n nginx 'username=liamg&password=.*'
# find a github api token across all processes
dismember grep 'gh[pousr]_[0-9a-zA-Z]{36}'
# search all accessible memory for common secrets
dismember scan
Isn't this information all just sitting in
/proc
?
Pretty much. Dismember just reads and presents it for the most part. If you can get away with grep whatever /proc/[pid]/blah
then go for it! I built this as an educational experience because I couldn't sleep one night and stayed up late reading the proc
man-pages (I live an extremely rock 'n' roll lifestyle). It's not a replacement for existing tools, but perhaps it can complement them.
Do you know how horrific some of these commands seem when read out of context?
Yes.
Vulnerable client-server application (VuCSA) is made for learning/presenting how to perform penetration tests of non-http thick clients. It is written in Java (with JavaFX graphical user interface).
Currently the vulnerable application contains the following challenges:
If you want to know how to solve these challenges, take a look at the PETEP website, which describes how to use the open-source tool PETEP to exploit them.
Tip: Before you start hacking, do not forget to check the data structure of messages bellow.
In order to run the vulnerable server and client, you can use one of releases on GitHub or run gradle assemble, which creates distribution packages (for both Windows and Unix). These packages contain sh/bat scripts that will run the server and client using JVM.
Project is divided into three modules:
Messages transmitted between server and client have the following simple format:
[type][target][length][payload]
32b 32b 32b ???
These four parts have the following meaning:
ZenBuster is a multi-threaded, multi-platform URL enumeration tool written in Python by Zach Griffin (@0xTas).
I wrote this tool as a way to deepen my familiarity with Python, and to help increase my understanding of Cybersecurity tooling in general. ZenBuster may not be the fastest or most comprehensive tool of its kind. It is however, simple to use, decently flexible, and in practice only marginally slower than other "tried-and-true" tools like Gobuster. Personally, I have been using it to help me solve CTF challenges on platforms like TryHackMe, and have found my implementation to be satisfactorily reliable.
This software is intended for use in CTF challenges, or by security professionals to gather information on their targets:
ZenBuster is capable of producing a potentially unwelcome number of HTTP requests in a short amount of time.
The developers and contributors are not liable or responsible for any damage caused by misuse or abuse of this software.

Firstly, ensure that Python version >= 3.6 is installed, then clone the repository with:
git clone https://github.com/0xTas/zenbuster.git
Next, cd zenbuster
.
ZenBuster relies on 3 external libraries to function, and it is recommended to install these with:
pip install -r requirements.txt
The modules that will be installed and their purposes are as follows:
These dependencies may be installed manually, with pip
using requirements.txt, or via interaction with the script upon first run.
Once dependencies have been installed, you can run the program in the following ways:
./zenbuster.py [options]
