Celerystalk - An Asynchronous Enumeration and Vulnerability Scanner

celerystalk helps you automate your network scanning/enumeration process with asynchronous jobs (aka tasks) while retaining full control of which tools you want to run.

• Configurable - Some common tools are in the default config, but you can add any tool you want
• Service Aware - Uses nmap/nessus service names rather than port numbers to decide which tools to run
• Scalable - Designed for scanning multiple hosts, but works well for scanning one host at a time
• VirtualHosts - Supports subdomain recon and virtualhost scanning
• Job Control - Supports canceling, pausing, and resuming of tasks, inspired by Burp scanner
• Screenshots Automatically takes screenshots of every url identified via brute force (gobuster) and spidering (Photon)

Using celerystalk - Some more detail

1. Configure which tools you'd like celerystalk to execute: The install script drops a config.ini file in the celerystalk folder. The config.ini script is broken up into three sections:
   Service Mapping - The first section normalizes Nmap & Nessus service names for celerystalk (this idea was created by @codingo_ in Reconnoitre AFAIK).
   

   [nmap-service-names]
   http = http,http-alt,http-proxy,www,http?
   https = ssl/http,https,ssl/http-alt,ssl/http?
   ftp = ftp,ftp?
   mysql = mysql
   dns = dns,domain,domain

   Domain Recon Tools - The second section defines the tools you'd like to use for subdomain discovery (an optional feature):
   

   [domain-recon]
   amass               : /opt/amass/amass -d [DOMAIN]
   sublist3r           : python /opt/Sublist3r/sublist3r.py -d [DOMAIN]

   Service Configuration - The rest of the confi.ini sections define which commands you want celerystalk to run for each identified service (i.e., http, https, ssh).
   
   • Disable any command by commenting it out with a ; or a #.
   • Add your own commands using [TARGET],[PORT], and [OUTPUT] placeholders.
   Here is an example:
   

   [http]
   whatweb             : whatweb http://[TARGET]:[PORT] -a3 --colour=never > [OUTPUT].txt
   cewl                : cewl http://[TARGET]:[PORT]/ -m 6 -w [OUTPUT].txt
   curl_robots         : curl http://[TARGET]:[PORT]/robots.txt --user-agent 'Googlebot/2.1 (+http://www.google.com/bot.html)' --connect-timeout 30 --max-time 180  > [OUTPUT].txt
   nmap_http_vuln      : nmap -sC -sV -Pn -v -p [PORT] --script=http-vuln* [TARGET] -d -oN [OUTPUT].txt -oX [OUTPUT].xml --host-timeout 120m --script-timeout 20m
   nikto               : nikto -h http://[TARGET] -p [PORT] &> [OUTPUT].txt
   gobuster-common     : gobuster -u http://[TARGET]:[PORT]/ -k -w /usr/share/seclists/Discovery/Web-Content/common.txt -s '200,204,301,302,307,403,500' -e -n -q > [OUTPUT].txt
   photon              : python /opt/Photon/photon.py -u http://[TARGET]:[PORT] -o [OUTPUT]
   ;gobuster_2.3-medium : gobuster -u http://[TARGET]:[PORT]/ -k -w /usr/share/wordlists/dirbuster/directory-list-lowercase-2.3-medium.txt -s '200,204,301,307,403,500' -e -n -q > [OUTPUT].txt

2. Run Nmap or Nessus:
   
   • Nmap: Run nmap against your target(s). Required: enable version detection (-sV) and output to XML (-oX filename.xml). All other nmap options are up to you. Here are some examples:

      nmap target(s) -Pn -p- -sV -oX filename.xml 
      nmap -iL target_list.txt -Pn -sV -oX filename.xml

   • Nessus: Run nessus against your target(s) and export results as a .nessus file
3. Create worksapce:
   

   Option	Description
   no options	Prints current workspace
   create	Creates new workspace
   -w	Define new workspace name
   -o	Define output directory assigned to workspace

     Create default workspace    ./celerystalk workspace create -o /assessments/client
     Create named workspace      ./celerystalk workspace create -o /assessments/client -w client
     Switch to another worksapce ./celerystalk workspace client

4. Import Data: Import data into celerystalk
   

   Option	Description
   -f scan.xml	Nmap/Nessus xml Adds all IP addresses from this file to hosts table and marks them all in scope to be scanned. Adds all ports and service types to services table.
   -S scope.txt	Scope file Show file differences that haven't been staged
   -D subdomains.txt	(sub)Domains file celerystalk determines whether each subdomain is in scope by resolving the IP and looking for IP in the DB. If there is a match, the domain is marked as in scope and will be scanned.

   Import Nmap XML file:       ./celerystalk import -f /assessments/nmap.xml 
   Import Nessus file:         ./celerystalk import -f /assessments/scan.nessus 
   Import list of Domains:     ./celerystalk import -D <file>
   Import list of IPs/Ranges:  ./celerystalk import -S <file>
   Specify workspace:          ./celerystalk import -f <file>     
   Import multiple files:      ./celerystalk import -f nmap.xml -S scope.txt -D domains.txt

5. Find Subdomains (Optional): celerystalk will perform subdomain recon using the tools specified in the config.ini.
   

   Option	Description
   -d domain1,domain2,etc	Run Amass, Sublist3r, etc. and store domains in DB After running your subdomain recon tools celerystalk determines whether each subdomain is in scope by resolving the IP and looking for IP in the DB. If there is a match, the domain is marked as in scope and will be scanned.

   Find subdomains:       celerystalk subdomains -d domain1.com,domain2.com

6. Launch Scan: I recommend using the import command first and running scan with no options, however you do have the option to do it all at once (import and scan) by using the flags below. celerystalk will submit tasks to celery which asynchronously executes them and logs output to your output directory.
   

   Option	Description
   no options	Scan all in scope hosts Reads DB and scans every in scope IP and subdomain. Launches all enabled tools for IPs, but only http/http specific tools against virtualhosts
   -t ip,vhost,cidr	Scan specific target(s) from DB or scan file Scan a subset of the in scope IPs and/or subdomains.
   -s	Simulation Sends all of the tasks to celery, but all commands are executed with a # before them rendering them inert.
   Use these only if you want to skip the import phase and import/scan all at once
   -f scan.xml	Import and process Nmap/Nessus xml before scan Adds all IP addresses from this file to hosts table and marks them all in scope to be scanned. Adds all ports and service types to services table.
   -S scope.txt	Import and process scope file before scan Show file differences that haven't been staged.
   -D subdomains.txt	Import and process (sub)domains file before scan celerystalk determines whether each subdomain is in scope by resolving the IP and looking for IP in the DB. If there is a match, the domain is marked as in scope and will be scanned.
   -d domain1,domain2,etc	Find Subdomains and scan in scope hosts After running your subdomain recon tools celerystalk determines whether each subdomain is in scope by resolving the IP and looking for IP in the DB. If there is a match, the domain is marked as in scope and will be scanned.

   Scan imported hosts/subdomains
   

   Scan all in scope hosts:    ./celerystalk scan    
   Scan subset of DB hosts:    ./celerystalk scan -t 10.0.0.1,10.0.0.3
                               ./celerystalk scan -t 10.0.0.100-200
                               ./celerystalk scan -t 10.0.0.0/24
                               ./celerystalk scan -t sub.domain.com
   Simulation mode:            ./celerystalk scan -s

   Import and Scan
   

   Start from Nmap XML file:   ./celerystalk scan -f /pentest/nmap.xml -o /pentest
   Start from Nessus file:     ./celerystalk scan -f /pentest/scan.nessus -o /pentest
   Scan all in scope vhosts:   ./celerystalk scan -f <file> -o /pentest -d domain1.com,domain2.com
   Scan subset hosts in XML:   ./celerystalk scan -f <file> -o /pentest -t 10.0.0.1,10.0.0.3
                               ./celerystalk scan -f <file> -o /pentest -t 10.0.0.100-200
                               ./celerystalk scan -f <file> -o /pentest -t 10.0.0.0/24
   Simulation mode:            ./celerystalk scan -f <file> -o /pentest -s

7. Rescan: Use this command to rescan an already scanned host.
   

   Option	Description
   no option	For each in scope host in the DB, celerystalk will ask if if you want to rescan it
   -t ip,vhost,cidr	Scan a subset of the in scope IPs and/or subdomains.

   Rescan all hosts:           ./celerystalk rescan
   Rescan some hosts           ./celerystalk rescan-t 1.2.3.4,sub.domain.com  
   Simulation mode:            ./celerystalk rescan -s   

8. Query Status: Asynchronously check the status of the tasks queue as frequently as you like. The watch mode actually executes the linux watch command so you don't fill up your entire terminal buffer.
   

   Option	Description
   no options	Shows all tasks in the defualt workspace
   watch	Sends command to the unix watch command which will let you get an updated status every 2 seconds
   brief	Limit of 5 results per status (pending/running/completed/cancelled/paused)
   summary	Shows only a banner with numbers and not the tasks themselves

   Query Tasks:                ./celerystalk query 
                               ./celerystalk query watch                               
                               ./celerystalk query brief
                               ./celerystalk query summary                                
                               ./celerystalk query summary watch

9. Cancel/Pause/Resume Tasks: Cancel/Pause/Resume any task(s) that are currently running or in the queue.
   

   Option	Description
   cancel	Canceling a running task will send a kill -TERM Canceling a queued task* will make celery ignore it (uses celery's revoke). Canceling all tasks* will kill running tasks and revoke all queued tasks.
   pause	Pausing a single task uses kill -STOP to suspend the process. Pausing all tasks* attemps to kill -STOP all running tasks, but it is a little wonky and you mind need to run it a few times. It is possible a job completed before it was able to be paused, which means you will have a worker that is still accepting new jobs.
   resume	Resuming tasks* sends a kill -CONT which allows the process to start up again where it left off.

   Cancel/Pause/Resume Tasks:  ./celerystalk <verb> 5,6,10-20          #Cancel/Pause/Resume tasks 5, 6, and 10-20 from current workspace
                               ./celerystalk <verb> all                #Cancel/Pause/Resume all tasks from current workspaces

10. Run Report: Run a report which combines all of the tool output into an html file and a txt file. Run this as often as you like. Each time you run the report it overwrites the previous report.
    

    Create Report:              ./celerystalk report                    #Create a report for all scanneed hosts in current workspace
    

    Screenshot:
    
    
11. Access the DB: List the workspaces, hosts, services, or paths stored in the celerystalk database
    

    Option	Description
    workspaces	Show all known workspaces and the output directory associated with each workspace
    services	Show all known open ports and service types by IP
    hosts	Show all hosts (IP addresses and subdomains/vhosts) and whether they are in scope and whether they have been submitted for scanning
    paths	Show all paths that have been identified by vhost
    -w workspace	Specify a non-default workspace

    Show workspaces:            ./celeryststalk db workspaces
    Show services:              ./celeryststalk db services    
    Show hosts:                 ./celeryststalk db hosts
    Show paths:                 ./celeryststalk db paths

12. Export DB: Export each table of the DB to a csv file
    

    Option	Description
    no options	Export the services, hosts, and paths table from the default database
    -w workspace	Specify a non-default workspace

    Export current DB:        ./celerystalk db export
    Export another DB:        ./celerystalk db export -w test
