CFRipper – CloudFormation Security Scanning & Audit Tool
CFRipper is a Python-based Library and CLI security analyzer that functions as an AWS CloudFormation security scanning and audit tool, it aims to prevent vulnerabilities from getting to production infrastructure through vulnerable CloudFormation scripts.
You can use CFRipper to prevent deploying insecure AWS resources into your Cloud environment. You can write your own compliance checks by adding new custom plugins.
CFRipper should be part of your CI/CD pipeline. It runs just before a CloudFormation stack is deployed or updated and if the CloudFormation script fails to pass the security check it fails the deployment and notifies the team that owns the stack. Rules are the heart of CFRipper. When running CFRipper the CloudFormation stack will be checked against each rule and the results combined.

Usage: [OPTIONS] [TEMPLATES]... Analyse AWS Cloudformation templates passed by parameter. Exit codes: - 0 = all templates valid and scanned successfully - 1 = error / issue in scanning at least one template - 2 = at least one template is not valid according to CFRipper (template scanned successfully) - 3 = unknown / unhandled exception in scanning the templates Options: --version Show the version and exit. --resolve / --no-resolve Resolves cloudformation variables and intrinsic functions [default: False] --resolve-parameters FILENAME JSON/YML file containing key-value pairs used for resolving CloudFormation files with templated parameters. For example, {"abc": "ABC"} will change all occurrences of {"Ref": "abc"} in the CloudFormation file to "ABC". --format [json|txt] Output format [default: txt] --output-folder DIRECTORY If not present, result will be sent to stdout --logging [ERROR|WARNING|INFO|DEBUG] Logging level [default: INFO] --rules-config-file FILENAME Loads rules configuration file (type: [.py, .pyc]) --rules-filters-folder DIRECTORY All files in the folder must be of type: [.py, .pyc] --aws-account-id TEXT A 12-digit AWS account number eg. 123456789012 --aws-principals TEXT A comma-separated list of AWS principals eg. arn:aws:iam::123456789012:root,234567890123, arn:aws:iam::111222333444:user/user-name --help Show this message and exit. |

CredNinja – Test Credential Validity of Dumped Credentials or Hashes
CredNinja is a tool to quickly test credential validity of dumped credentials (or hashes) across an entire network or domain very efficiently.
At the core of it, you provide it with a list of credentials you have dumped (or hashes, it can pass-the-hash) and a list of systems on the domain (the author suggests scanning for port 445 first, or you can use “–scan”). It will tell you if the credentials you dumped are valid on the domain, and if you have local administrator access to a host.

Required Arguments: -a accounts_to_test.txt, --accounts accounts_to_test.txt A word or file of user credentials to test. Usernames are accepted in the form of "DOMAIN\USERNAME:PASSWORD" -s systems_to_test.txt, --servers systems_to_test.txt A word or file of servers to test against. This can be a single system, a filename containing a list of systems, a gnmap file, or IP addresses in cidr notation. Each credential will be tested against each of these servers by attempting to browse C$ via SMB Optional Arguments: -t THREADS, --threads THREADS Number of threads to use. Defaults to 10 --ntlm Treat the passwords as NTLM hashes and attempt to pass-the-hash! --valid Only print valid/local admin credentials --invalid Only print invalid credentials -o OUTPUT, --output OUTPUT Print results to a file -p PASSDELIMITER, --passdelimiter PASSDELIMITER Change the delimiter between the account username and password. Defaults to ":" --delay SECONDS %JITTER Delay each request per thread by specified seconds with jitter (example: --delay 20 10, 20 second delay with 10% jitter) --timeout TIMEOUT Amount of seconds wait for data before timing out. Default is 15 seconds --stripe Only test one credential on one host to avoid spamming a single system with multiple login attempts (used to check validity of credentials). This will randomly select hosts from the provided host file. --scan Perform a quick check to see port 445 is available on the host before queueing it up to be processed --scan-timeout SCAN_TIMEOUT Sets the timeout for the scan specified by --scan argument. Default of 2 seconds -h, --help Get help about this script's usage --no-color Turns off output color. Written file is always colorless Additional Information Retrieval: --os Display the OS of the system if available (no extra request is being sent) --domain Display the primary domain of the system if available (no extra request is being sent) --users List the users that have logged in to the system in the last 6 months (requires LOCAL ADMIN). Returns usernames with the number of days since their home directory was changed. This sends one extra request to each host --users-time USERS_TIME Modifies --users to search for users that have logged in within the last supplied amount of days (default 100 days) |
The tool really shines on large networks where it can parse a large amount of hosts quite quickly.
It is intended to be run on Kali Linux

assetfinder – Find Related Domains and Subdomains
assetfinder is a Go-based tool to find related domains and subdomains that are potentially related to a given domain from a variety of sources including Facebook, ThreatCrowd, Virustotal and more.
assetfinder uses a variety of sources including those in the infosec space and social networks which can give relevant info:
- crt.sh
- certspotter
- hackertarget
- threatcrowd
- wayback machine
- dns.bufferover.run
- facebook – Needs FB_APP_ID and FB_APP_SECRET environment variables set (https://developers.facebook.com/) and you need to be careful with your app’s rate limits
- virustotal – Needs VT_API_KEY environment variable set (https://developers.virustotal.com/reference)
- findsubdomains – Needs SPYSE_API_TOKEN environment variable set (the free version always gives the first response page, and you also get “25 unlimited requests”) — (https://spyse.com/apidocs)
Sources to be implemented:
- http://api.passivetotal.org/api/docs/
- https://community.riskiq.com/ (?)
- https://riddler.io/
- http://www.dnsdb.org/
- https://certdb.com/api-documentation
Usage of assetfinder to Find Related Domains and Subdomains
The usage is very simple with only one option basically, to limit the search to subdomains only – by default it will scan for all associated domains and subdomains.

assetfinder [--subs-only] <domain> |
Installing assetfinder to Find Related Domains and Subdomains
If you have Go installed and configured (i.e. with $GOPATH/bin in your $PATH):
|
1 |
go get -u github.com/tomnomnom/assetfinder |
Another similar and recent tool that uses many of these sources and more and is also worth checking out is The OWASP Amass Project- DNS Enumeration, Attack Surface Mapping & External Asset Discovery.

Karkinos Beginner Friendly Penetration Testing Tool Features
- Encoding/Decoding characters
- Encrypting/Decrypting text or files
- Reverse shell handling
- Cracking and generating hashes
How to Install Karkinos Beginner Friendly Penetration Testing Tool
Dependencies are:
- Any server capable of hosting PHP
- Tested with PHP 7.4.9
- Tested with Python 3.8
- Make sure it is in your path as:
- Windows:
python - Linux:
python3 - If it is not, please change the commands in
includes/pid.php - Pip3
- Raspberry Pi Zero friendly :) (crack hashes at your own risk)
Then:
git clone https://github.com/helich0pper/Karkinos.gitcd Karkinos- pip3 install -r requirements.txt
cd wordlists && unzip passlist.zipYou can also unzip it manually using file explorer. Just make surepasslist.txtis in wordlists directory.- Make sure you have write privilages for
db/main.db - Enable
extension=mysqliin yourphp.inifile. - If you don’t know where to find this, refer to the PHP docs. Note: MySQLi is only used to store statistics.
- Thats it! Now just host it using your preferred web server or run:
php -S 127.0.0.1:8888in the Karkinos directory.
Important: using port 5555, 5556, or 5557 will conflict with the Modules
If you insist on using these ports, change the PORT value in:
- /bin/Server/app.py Line 87
- /bin/Busting/app.py Line 155
- /bin/PortScan/app.py Line 128
