| == Mapping host ==
| | Courses notes |
|
| |
|
| === Mapping open ports on host ===
| | * [[DESEC Security - Introduction to Pentest in Practice - course notes]] |
| nmap -D RND:20 --open -sS --top-ports=100 domain.com -oN open-ports.file
| | * [[UDEMY - TOTAL: CompTIA Security+ Certification (SY0-601) - course notes]] |
| | |
| * nmap - the comand
| |
| * -D RND:20 - will generate 20 random IPs to send the request, to try to mask the requests if there is a inteligent firewall on the other side. | |
| * --open - to get open ports
| |
| * -sS - SYN scan the target responds with a '''SYN-ACK''' packet (acknowledging the connection)
| |
| * --top-ports=100 - list the top 100 ports
| |
| * domain.com the host you want to map
| |
| * -oN - output name, or, output save to the file named open-ports.file
| |
| | |
| Optionals
| |
| | |
| * -p- - will scan all 65535 ports of the server
| |
| * --min-rate=N - will send N packages per second
| |
| | |
| === Mapping services on ports ===
| |
| nmap --open -sV -pP1,P2... domain.com -oN services-on-ports.file
| |
| | |
| * -sV - to scan the service on the port (scan version)
| |
| * -pP1,P2 - scan just port P1 and P2 but you can use any number of ports (e.g. -p80,443,22)
| |
| | |
| === Search exposed interfaces ===
| |
| gobuster dir -u <nowiki>http://dominio.com/</nowiki> -w /word-list.txt -t 100 -e --no-error -r -o exposed-interfaces.file
| |
| | |
| * gobuster - the command
| |
| * dir - uses directory/file enumeration mode
| |
| * -u - URL
| |
| * -w - word list
| |
| * -t 100 - uses 100 paralel threads for reducing search time
| |
| * -e - shows extended log
| |
| * --no-error - do not returns errors
| |
| * -r - follow redirects
| |
| * -o exposed-interfaces.file - save output to exposed-interfaces.file
| |
| | |
| === FTP brute force test ===
| |
| hydra -v -t10 -l user -p password <nowiki>ftp://domain.com</nowiki> -s PORT
| |
| or
| |
| hydra -v -t10 -L /users-list.file -P /passwords-list.file -s PORT
| |
| | |
| * hydra - the command
| |
| * -v - verbose
| |
| * -t10 - use 10 threads to make things quickly
| |
| * -l - use a specific username
| |
| * -L - use a list of usernames
| |
| * -p - use a specific password
| |
| * -P - use a list of passwords
| |
| * -s - specify the port, if not will use the default one (21)
| |
| | |
| === WEB brute force test ===
| |
| Install Burp Suite, go to intercept and turn it on, open the browser,
| |
| [[File:Fmwynvpbcxgwkq.png|none|thumb|600x600px]]
| |
| access the login interface, intercept the request that sends the authentication, send it to repeater and instruder,
| |
| [[File:Djukezotdnmggziq.png|none|thumb|600x600px]] | |
| then go to the repeater and repeat many times to test if the application is susceptible to brute force attacks,
| |
| [[File:Etfqtexbpgubqvpm.png|none|thumb|600x600px]]
| |
| then go to the intruder > positions and put a §§ on the password field,
| |
| [[File:Jsrsahvkbgvkkxzm.png|none|thumb|600x600px]]
| |
| then go to payloads, set payload type to runtime file and then select a file with the password
| |
| [[File:Cefrtaxjxiqcpntj.png|none|thumb|600x600px]]
| |
| result:
| |
| [[File:Fjhxfyxkbpslkuy.png|none|thumb|600x600px]]
| |
| 14 requests in a row and none was blocked by brute force tests.
