Nytro Posted January 25, 2023 Report Posted January 25, 2023 Lepus Lepus is a tool for enumerating subdomains, checking for subdomain takeovers and perform port scans - and boy, is it fast! Basic Usage lepus.py yahoo.com Summary Enumeration modes Subdomain Takeover Port Scan Installation Arguments Full command example Enumeration modes The enumeration modes are different ways lepus uses to identify sudomains for a given domain. These modes are: Collectors Dictionary Permutations Reverse DNS Markov Moreover: For all methods, lepus checks if the given domain or any generated potential subdomain is a wildcard domain or not. After identification, lepus collects ASN and network information for the identified domains that resolve to public IP Addresses. Collectors The Collectors mode collects subdomains from the following services: Service API Required AlienVault OTX No Anubis-DB No Bevigil Yes BinaryEdge Yes BufferOver Yes C99 Yes Censys Yes CertSpotter No CommonCrawl No CRT No DNSDumpster No DNSRepo Yes DNSTrails Yes Farsight DNSDB Yes FOFA Yes Fullhunt Yes HackerTarget No HunterIO Yes IntelX Yes LeakIX Yes Maltiverse No Netlas Yes PassiveTotal Yes Project Discovery Chaos Yes RapidDNS No ReconCloud No Riddler Yes Robtex Yes SecurityTrails Yes Shodan Yes SiteDossier No ThreatBook Yes ThreatCrowd No ThreatMiner No URLScan Yes VirusTotal Yes Wayback Machine No Webscout No WhoisXMLAPI Yes ZoomEye Yes You can add your API keys in the config.ini file. The Collectors module will run by default on lepus. If you do not want to use the collectors during a lepus run (so that you don't exhaust your API key limits), you can use the -nc or --no-collectors argument. Dictionary The dictionary mode can be used when you want to provide lepus a list of subdomains. You can use the -w or --wordlist argument followed by the file. A custom list comes with lepus located at lists/subdomains.txt. An example run would be: lepus.py -w lists/subdomains.txt yahoo.com Permutations The Permutations mode performs changes on the list of subdomains that have been identified. For each subdomain, a number of permutations will take place based on the lists/words.txt file. You can also provide a custom wordlist for permutations with the -pw or --permutation-wordlist argument, followed by the file name.An example run would be: lepus.py --permutate yahoo.com or lepus.py --permutate -pw customsubdomains.txt yahoo.com ReverseDNS The ReverseDNS mode will gather all IP addresses that were resolved and perform a reverse DNS on each one in order to detect more subdomains. For example, if www.example.com resolves to 1.2.3.4, lepus will perform a reverse DNS for 1.2.3.4 and gather any other subdomains belonging to example.com, e.g. www2,internal or oldsite. To run the ReverseDNS module use the --reverse argument. Additionally, --ripe (or -ripe) can be used in order to instruct the module to query the RIPE database using the second level domain for potential network ranges. Moreover, lepus supports the --ranges (or -r) argument. You can use it to make reverse DNS resolutions against CIDRs that belong to the target domain. By default this module will take into account all previously identified IPs, then defined ranges, then ranges identified through the RIPE database. In case you only want to run the module against specific or RIPE identified ranges, and not against all already identified IPs, you can use the --only-ranges (-or) argument. An example run would be: lepus.py --reverse yahoo.com or lepus.py --reverse -ripe -r 172.216.0.0/16,183.177.80.0/23 yahoo.com or only against the defined or identified from RIPE lepus.py --reverse -or -ripe -r 172.216.0.0/16,183.177.80.0/23 yahoo.com Hint: lepus will identify ASNs and Networks during enumeration, so you can also use these ranges to identify more subdomains with a subsequent run. Markov With this module, Lepus will utilize Markov chains in order to train itself and then generate subdomain based on the already known ones. The bigger the general surface, the better the tool will be able to train itself and subsequently, the better the results will be. The module can be activated with the --markovify argument. Parameters also include the Markov state size, the maximum length of the generated candidate addition, and the quantity of generated candidates. Predefined values are 3, 5 and 5 respectively. Those arguments can be changed with -ms (--markov-state), -ml (--markov-length) and -mq (--markov-quantity) to meet your needs. Keep in mind that the larger these values are, the more time Lepus will need to generate the candidates. It has to be noted that different executions of this module might generate different candidates, so feel free to run it a few times consecutively. Keep in mind that the higher the -ms, -ml and -mq values, the more time will be needed for candidate generation. lepus.py --markovify yahoo.com or lepus.py --markovify -ms 5 -ml 10 -mq 10 Subdomain Takeover Lepus has a list of signatures in order to identify if a domain can be taken over. You can use it by providing the --takeover argument. This module also supports Slack notifications, once a potential takeover has been identified, by adding a Slack token in the config.ini file.

You can use the --portscan argument which by default will scan ports 80, 443, 8000, 8080, 8443. You can also use custom ports or choose a predefined set of ports. Ports set Ports small 80, 443 medium (default) 80, 443, 8000, 8080, 8443 large 80, 81, 443, 591, 2082, 2087, 2095, 2096, 3000, 8000, 8001, 8008, 8080, 8083, 8443, 8834, 8888, 9000, 9090, 9443 huge 80, 81, 300, 443, 591, 593, 832, 981, 1010, 1311, 2082, 2087, 2095, 2096, 2480, 3000, 3128, 3333, 4243, 4567, 4711, 4712, 4993, 5000, 5104, 5108, 5800, 6543, 7000, 7396, 7474, 8000, 8001, 8008, 8014, 8042, 8069, 8080, 8081, 8088, 8090, 8091, 8118, 8123, 8172, 8222, 8243, 8280, 8281, 8333, 8443, 8500, 8834, 8880, 8888, 8983, 9000, 9043, 9060, 9080, 9090, 9091, 9200, 9443, 9800, 9943, 9980, 9981, 12443, 16080, 18091, 18092, 20720, 28017 An example run would be: lepus.py --portscan yahoo.com or lepus.py --portscan -p huge yahoo.com or lepus.py --portscan -p 80,443,8082,65123 yahoo.com Installation Normal installation: $ python3.7 -m pip install -r requirements.txt Preferably install in a virtualenv: $ pyenv virtualenv 3.7.4 lepus $ pyenv activate lepus $ pip install -r requirements.txt Installing latest python on debian: $ apt install build-essential zlib1g-dev libncurses5-dev libgdbm-dev libnss3-dev libssl-dev libreadline-dev libffi-dev libsqlite3-dev wget $ curl -O https://www.python.org/ftp/python/3.7.4/Python-3.7.4.tar.xz $ tar -xf Python-3.7.4.tar.xz $ cd Python-3.7.4 $ ./configure --enable-optimizations --enable-loadable-sqlite-extensions $ make $ make altinstall Arguments usage: lepus.py [-h] [-w WORDLIST] [-hw] [-t THREADS] [-nc] [-zt] [--permutate] [-pw PERMUTATION_WORDLIST] [--reverse] [-r RANGES] [--portscan] [-p PORTS] [--takeover] [--markovify] [-ms MARKOV_STATE] [-ml MARKOV_LENGTH] [-mq MARKOV_QUANTITY] [-f] [-v] domain Infrastructure OSINT positional arguments: domain domain to search optional arguments: -h, --help show this help message and exit -w WORDLIST, --wordlist WORDLIST wordlist with subdomains -hw, --hide-wildcards hide wildcard resolutions -t THREADS, --threads THREADS number of threads [default is 100] -nc, --no-collectors skip passive subdomain enumeration -zt, --zone-transfer attempt to zone transfer from identified name servers --permutate perform permutations on resolved domains -pw PERMUTATION_WORDLIST, --permutation-wordlist PERMUTATION_WORDLIST wordlist to perform permutations with [default is lists/words.txt] --reverse perform reverse dns lookups on resolved public IP addresses -ripe, --ripe query ripe database with the 2nd level domain for networks to be used for reverse lookups -r RANGES, --ranges RANGES comma seperated ip ranges to perform reverse dns lookups on -or, --only-ranges use only ranges provided with -r or -ripe and not all previously identifed IPs --portscan scan resolved public IP addresses for open ports -p PORTS, --ports PORTS set of ports to be used by the portscan module [default is medium] --takeover check identified hosts for potential subdomain take- overs --markovify use markov chains to identify more subdomains -ms MARKOV_STATE, --markov-state MARKOV_STATE markov state size [default is 3] -ml MARKOV_LENGTH, --markov-length MARKOV_LENGTH max length of markov substitutions [default is 5] -mq MARKOV_QUANTITY, --markov-quantity MARKOV_QUANTITY max quantity of markov results per candidate length [default is 5] -f, --flush purge all records of the specified domain from the database -v, --version show program's version number and exit Full command example The following, is an example run with all available active arguments: ./lepus.py python.org --wordlist lists/subdomains.txt --permutate -pw ~/mypermsword.lst --reverse -ripe -r 10.11.12.0/24 --portscan -p huge --takeover --markovify -ms 3 -ml 10 -mq 10 The following command flushes all database entries for a specific domain: ./lepus.py python.org --flush Sursa: https://github.com/GKNSB/Lepus 1 1 Quote
