[Analyst Arsenal (A²)™]

A toolkit for Security Researchers

Description

With aa_adhoc, run through a list of URLs and check sites for malicious files based on predefined file extensions.

With aa_certstream, find out when a phishing kit has been staged on a domain. With this information, you can be amongst the first to:

• Know
• Block
• Report
• Analyze

With aa_urlscan, easily search urlscan.io and check sites for malicious files based on predefined file extensions.

With aa_whoisds, download a list of newly registered domains from WHOIS Domain Search, score the domains, and search for signs of malicious activity.

Prerequisites

• Ubuntu 18.04+ (should work on other Linux distros)
• Python 2.7.14
• DEB Packages:
  • gcc
  • Git (optional)
  • Torsocks (optional: used with flag --tor)

Setup

1. Open a terminal and run the following command:

   git clone https://github.com/ecstatic-nobel/Analyst-Arsenal.git  
   cd Analyst-Arsenal  
   bash py_pkg_update.sh  

Usage

aa_adhoc
The following command will:

• Make requests to the domains retrieved from a file
• Download files from the site when an open directory is found hosting a file with the desired file extension

1 positional arguments needed:

• Input File : Path to the file containing URLs

Optional arguments:

• --directory : Download data to CAP_DIR (default: ./Captures)
• --level : Recursion depth (default=1, infinite=0)
• --max-redirect : Maximum redirects (default=0)
• --quiet : Don't show wget output
• --threads : Numbers of threads to spawn
• --timeout : Set the connection timeout to TIMEOUT
• --tor : Download files via the Tor network
• --very-verbose : Show error messages

python aa_adhoc.py <INPUT_FILE> [--directory] [--level] [--max-redirect] [--quiet] [--threads] [--timeout] [--tor] [--very-verbose]  

aa_certstream
The following command will:

• Stream CT logs via Certstream
• Score and add suspicious domains to a queue while other domains continue to be scored
• Simultaneously make requests to the domains in the queue to search for predefined file extensions
• Recursively download the site when an open directory is found hosting a file with a particular extension

Optional arguments:

• --ctl-server : Certstream server URL to connect to
• --dns-twist : Check the twisted keywords found in dns_twisted.yaml
• --directory : Download data to CAP_DIR (default: ./Captures)
• --level : Recursion depth (default=1, infinite=0)
• --log-nc : File to store domains that have not been checked
• --quiet : Don't show wget output
• --score : Minimum score to trigger a session (Default: 75)
• --threads : Numbers of threads to spawn
• --timeout : Set the connection timeout to TIMEOUT
• --tor : Download files via the Tor network
• --verbose : Show domains being scored
• --very-verbose : Show error messages

python aa_certstream.py [--ctl-server] [--dns-twist] [--directory] [--level] [--log-nc] [--quiet] [--score] [--threads] [--timeout] [--tor] [--verbose] [--very-verbose]  

aa_urlscan
The following command will:

• Make requests to the domains retrieved from urlscan.io
• Recursively download the site when an open directory hosting a file with the desired file extension

3 positional arguments needed:

• Query Type : automatic, manual, certstream, openphish, phishtank, twitter, urlhaus
• Delta : Number of days back to search (GMT)
• Query String : String to search (and does not include spaces)

Optional arguments:

• --directory : Download data to CAP_DIR (default: ./Captures)
• --level : Recursion depth (default=1, infinite=0)
• --max-redirect : Maximum redirects (default=0)
• --quiet : Don't show wget output
• --threads : Numbers of threads to spawn
• --timeout : Set the connection timeout to TIMEOUT
• --tor : Download files via the Tor network
• --very-verbose : Show error messages

python aa_urlscan.py <QUERY_TYPE> <DELTA> <QUERY_STRING> [--directory] [--level] [--max-redirect] [--quiet] [--threads] [--timeout] [--tor] [--very-verbose]  

Note: If the path is a file, it will be automatically downloaded.

aa_whoisds

• Download a list of newly registered domains from WHOIS Domain Search (whoisds.com)
• Score and add suspicious domains to a queue while other domains continue to be scored
• Simultaneously make requests to the domains in the queue to search for predefined file extensions
• Recursively download the site when an open directory is found hosting a file with a particular extension

1 positional argument needed:

• Delta : Number of days back to search (GMT)

Optional arguments:

• --dns-twist : Check the twisted keywords found in dns_twisted.yaml
• --directory : Download data to CAP_DIR (default: ./Captures)
• --level : Recursion depth (default=1, infinite=0)
• --log-nc : File to store domains that have not been checked
• --quiet : Don't show wget output
• --score : Minimum score to trigger a session (Default: 75)
• --threads : Numbers of threads to spawn
• --timeout : Set the connection timeout to TIMEOUT
• --tor : Download files via the Tor network
• --verbose : Show domains being scored
• --very-verbose : Show error messages

python aa_whoisds.py <DELTA> [--dns-twist] [--directory] [--level] [--log-nc] [--quiet] [--score] [--threads] [--timeout] [--tor] [--verbose] [--very-verbose]  

Things to know

• Be responsible!!!
• Output messages:
  • Complete: download complete or the site canceled it prematurely
  • Critical: a domain was found with a score above 120
  • Directory: the output directory is unavailable
  • Download: checks passed and a download was started
  • Empty: the output directory was empty and removed
  • Failed: a connection to the site couldn't be made
  • Session: checking the site for data included in external.yaml
  • Suspicious: a domain was found with a score above 90
  • Triggered: a domain was found with the minimum score specified
• Check the queue_file.txt file to get a better understanding of how large the queue is. If it's too large, either increase the threads, raise the score, or decrease the level.
• If the keywords in config.yaml have been modified and --dns-twist is going to be used, regenerate dns_twisted.yaml by running the following command:

  bash dnstwist.sh PATH_TO_DNSTWIST_SCRIPT

• Using the --dns-twist flag will default to a minimum of 20 threads
• Downloads via Tor happen over 127.0.0.1:9050
• These scripts will not check Torsocks settings
