Meterpreter [11]

$ clearev   # Clear all event logs (Application, System, Security)

Windows machines

  • Download clearlogs.exe
  • Run: clearlogs.exe -sec NOTICE: You will need physical access to the victims system

Linux systems

$ kwrite /var/log/messages  # Delete all or specific entries
NOTICE: You can use any other text editor

Erasing the Command History

$ more ~/.bash_history      # Command history
$ echo $HISTSIZE            # The size of our history file
$ export HISTSIZE=0         # Set the histoty file size to zero

Shredding the History File

$ shred -zu root/.bash_history      # The shred command with the -zu switches will overwrite the history with zeros and delete the file.

The logs [12]

$ WTMP      # Every log on/off, with login/logout time plus tty and host
$ UTMP      # Who is online at the moment
$ LASTLOG   # Where did the logins come from

Linux scripting

Understanding bash scripting [27]

Ping sweep without NMAP [28]

$ for i in `seq 1 255`; do ping -c 1 10.10.10.$i | tr \\n ' ' | awk '/1 received/ {print $2}'; done
$ for i in {1..254}; do ping -c 1 -W 1 10.1.1.$i | grep 'from'; done

Fork bomb [29]

$ :(){ :|:& };:     # forkbomb(){ forkbomb | forkbomb & }; forkbomb

Monitor DNS [30]

-It takes the IP address or hostname of the DNS server to check. Checks the records defined in the array.

//Define defaults
if($_SERVER[argv][1])
{
$ns_server = $_SERVER[argv][1];
} else {
echo "You need to supply a DNS server to check. Quitting.\n";
exit;
}
$hosts = array("zabbix.com" => "85.113.250.92",
"php.net" => "69.147.83.197");
// Do query
foreach($hosts as $host => $ip)
{
$result = shell_exec("dig +time=1 +tries=1 +short @".$ns_server." ".$host);
if(!preg_match('/'.$ip.'/', $result))
{
$failed = TRUE;
}
}
if($failed)
{
echo "0\n";
} else {
echo "1\n";
}
?>

Monitoring NTP [31]

#!/usr/local/bin/bash
#ntptest
#NTP test scripts for Zabbix monitor. Conditional return
# of 1=success | 0= for failed response
HOST_QUERY=$1
if [`ntpq -pn $HOST_QUERY | grep -E -c '^\*'` -eq 1 ]; then
#Sync responded, OK
echo "1"
else
echo "0"
fi

NOTICE: Works with *nix Zabbix Server

Special shell variables to be aware [32]

$ $*    # Passes in all of the arguments. This is useful for FOR loops
$ $?    # Gets the error code (exit()) status) of the last program executed
$ $$    # Gets the PID of the current shell.
$ $!    # Gets the PID of the last background process
$ $EUID # Gets the effective UID number of the scripts execution

Linux Iptables Firewall Shell Script For Standalone Server [33]

IP Tables

Create a set named geoset[13]

$ sudo ipset create geoblock hash:net,port

Loop that runs banning list of countries from reaching the service of SSHD

for IP in $(wget -O –                                                               http://www.ipdeny.com/ipblocks/data/countries/{cn,ru,kr,pk,tw,sg,hk}.zone)
do
# regular ban - block port 22 for countryXX
sudo ipset add geoblock $IP,22
done

Preview of the list

#  sudo ipset list geoblock

Delete whole list

# sudo ipset del geoblock|"setname"

Add rules to IPtables

# sudo iptables -I INPUT -m set --set geoblock src -j DROP

Save IPtables

# service iptables save

Reverse function

# sudo iptables -A INPUT -m set --set !geoblock src -j DROP

Connection States [14]

#iptables -A INPUT -p tcp --dport ssh -s 10.10.10.10 -m state --state NEW,ESTABLISHED -j ACCEPT
#iptables -A OUTPUT -p tcp --sport 22 -d 10.10.10.10 -m state --state ESTABLISHED -j ACCEPT

Example

[1]

tmpdir=${TMPDIR:-/tmp}/pssh.$$
mkdir -p $tmpdir
count=0
while IFS= read -r userhost; do
    ssh -n -o BatchMode=yes ${userhost} 'uname -a' > ${tmpdir}/${userhost} 2>&1 &

done < userhost.lst
while [ $count -gt 0 ]; do
    wait $pids
    count=`expr $count - 1`
done
echo "Output for hosts are in $tmpdir"

CHKCONFIG

The chkconfig utility is a command-line tool that allows you to specify in which runlevel to start a selected service, as well as to list all available services along with their current setting.[3]

$ chkconfig --list                              # Listing the Services
$ chkconfig --list service_name                 # Display the current settings for a selected service only
$ chkconfig service_name on                     # Enabling a Service
$ chkconfig service_name on --level runlevels   # To enable a service in certain runlevels only
$ chkconfig service_name off                    # Disabling a Service

They use a variety of communication technologies and many work on all Windows operating systems that Windows PowerShell supports without any special configuration.[42]

Typically, cmdlets that support remoting without special configuration have the ComputerName parameter and do not have the Session parameter. To find these cmdlets in your session, type:

Get-Command | where { $_.parameters.keys -contains "ComputerName" -and $_.parameters.keys -notcontains "Session"}

Start an Interactive Session

To start an interactive session with a single remote computer, we use the Enter-PSSession cmdlet.

Enter-PSSession Server01

Exit Session

Exit-PSSession

Running a remote command

To run any command on one or many remote computers, use the Invoke-Command cmdlet. For example, to run a Get-UICulture command on the Server01 and Server02 remote computers, type:

Invoke-Command -ComputerName Server01, Server02 {Get-UICulture}

Output example

Untitled.png

Run a script

Invoke-Command -ComputerName Server01, Server02 -FilePath c:\Scripts\DiskCollect.ps1

Establish a Persistent Connection

Following command creates a remote session on the Server01 computer and another remote session on the Server02 computer. It saves the session objects in the $s variable.

$s = New-PSSession -ComputerName Server01, Server02

following command creates a remote session on the Server01 computer and another remote session on the Server02 computer. It saves the session objects in the $s variable.

Invoke-Command -Session $s {$h = Get-HotFix}

Now you can use the data in the $h variable in subsequent commands, such as the following one. The results are displayed on the local computer.

Invoke-Command -Session $s {$h | where {$_.installedby -ne "NTAUTHORITY\SYSTEM"}}

Windows network commands

$ Netstat                   # The netstat command is used to display the TCP/IP network protocol statistics and information
$ Nslookup                  # The nslookup MS-DOS utility that enables a user to do a reverse lookup on an IP address of a domain or host on a network
$ Route                     # The route MS-DOS utility enables computers to view and modify the computer's route table
& Tracert and traceroute    # It allows you to view a listing of how a network packet travels through the network and where it may fail or slow down
$ Whois                     # The whois command available in Unix and Linux variants helps allow a user to identify a domain name. This command provides information about a domain name much like the WHOIS on network solutions.
$ Winipcfg                  # The winipcfg command available in Windows allows a user to display network and network adapter information. Here, a user can find such information as an IP address, Subnet Mask, Gateway, etc.

Hidden tools in Command Line

NOTICE: You need to run CMD with administrator privileges [10]

System file checker

$ sfc /scannow      # This performs an immediate scan of your system and will replace files as necessary. You may need to restart Windows when it's done if it finds problems
$ sfc /scanonce     # This performs a scan the next time you restart your system
$ sfc /scanboot     # This schedules a scan to be performed every time you restart your system
$ sfc Revert        # This returns the System File Checker to its default settings. You can use it to turn off the /scanboot option, for example

Check disk

$ chkdsk Volume     # If you want to check a whole drive, just type the drive letter
$ chkdsk Filename   # You can also use chkdsk to check a single file or group of files
$ chkdsk /F         # Run it with this option to have chkdsk go ahead and fix those errors
$ chkdsk /R         # This option forces chkdsk to locate bad sectors and recover information from them. If chkdsk cannot lock the disk (which it usually can't since you're actually using Windows), it will prompt you run the command the next time you restart Windows

Cipher

$ cipher /W:pathname    # The /W option removes data on unused portions of a volume, effectively erasing data that may be hanging around on your hard drive after deletion. You can point cipher at an entire volume (like C:) or a specific folder

NOTICE: This applies to traditional hard drives and not SSDs

Driverquery

$ driverquery /s        # This option lets you specify the name or IP address of a remote computer so that you investigate the drivers it has installed
$ driverquery /si       # This option shows you the digital signature information for drivers
$ driverquery /fo       # This is really the key option you'll use with driverquery. It lets you specify the format in which information is displayed so that you can more effectively save it as a report.

Example: driverquery /fo CSV > drivers.csv

WMIC

WMIC extends WMI for operation from several command-line interfaces and through batch scripts. Before WMIC, you used WMI-based applications (such as SMS), the WMI Scripting API, or tools such as CIM Studio to manage WMI-enabled computers. Without a firm grasp on a programming language such as C++ or a scripting language such as VBScript and a basic understanding of the WMI namespace, do-it-yourself systems management with WMI was difficult. WMIC changes this situation by giving you a powerful, user-friendly interface to the WMI namespace.[51]

Windows registry

Structure of the Windows Registry (hives)[56]

HKEY_CLASSES_ROOT   # Information stored here ensures that the correct program opens when it is executed in Windows Explorer. 
HKEY_CURRENT_USER   # Contains configuration information for the user who is currently logged into the system, including user's folders, screen colors, and Control Panel settings
HKEY_LOCAL_MACHINE  # Contains machine hardware-specific information that the operating system runs on
HKEY_USERS          # Contains configuration information of all user profiles on the system, which concerns application configurations, and visual settings
HKEY_CURRENT_CONFIG # Stores information about the systems current configuration. Alias for: HKLM\Config\profile

MRU lists

MRU, or 'most recently used' lists contain entries made due to specific actions performed by the user. There are numerous MRU lists located throughout various Registry keys.

HKCU\Software\Microsoft\Windows\ CurrentVersion\Explorer\RunMRU

UserAssist

The UserAssist key contains two or more subkeys which have long hexadecimal names that appear as globally unique identifiers (GUIDs). Each subkey records values that pertain to specific objects the user has accessed on the system, such as Control Panel applets, shortcut files, programs, etc.

HCU\Software\Microsoft\Windows\CurrentVersion\Explorer\UserAssist

These values however, are encoded using a ROT- 13 encryption algorithm, sometimes known as a Caesar cipher. This particular encryption technique is quite easy to decipher, as each character is substituted with the character 13 spaces away from it in the ASCII table. With the UserAssist key, a forensic examiner can gain a better understanding of what types of files or applications have been accessed on a particular system.

ff05:: 	# Site local: is intended to span a single site
ff08:: 	# Organization scope: Intended to span multiple sizes within the same organization
ff0e:: 	# Global scope, assigned by IANA
ff01:: 	# Interface local: Spans only a single interface on a node and is useful only for loopback transmission of multicast

Interface adresses [22]

fe80::          # link-local
2001::          # routable
::a.b.c.d       # IPv4 compatible IPv6
::ffff:a.b.c.d  # IPv4 mapped IPv6

SNMP

Concept [43]

snmp.png

Command Examples [44]

This command returns an administratively assigned name for this managed node.

% snmpget -mALL -v1 -cpublic snmp_agent_Ip_address sysName.0

The snmpwalk command performs a sequence of chained GETNEXT requests automatically. It is a work saving command.

% snmpwalk -mALL -v1 -cpublic snmp_agent_Ip_address system

The snmpbulkwalk command uses the GETBULK SNMP protocol feature to query for an entire tree of information about a network entity

% snmpbulkwalk -mALL -v2c -cprivate snmp_agent_Ip_address entPhysicalTable>time7

Packet Capturing

[38]

tcpdump -i eth0                     # Capture Packets From Specific Interface
tcpdump -c 5 -i eth0                # Capture Only N Number of Packets
tcpdump -A -i eth0                  # Print Captured Packets in ASCII
tcpdump -D                          # Display Available Interfaces  
tcpdump -XX -i eth0                 # Display Captured Packets in HEX and ASCII
tcpdump -w 0001.pcap -i eth0        # Capture and Save Packets in a File
tcpdump -r 0001.pcap                # Read Captured Packets File
tcpdump -n -i eth0                  # Capture IP address Packets
tcpdump -i eth0 tcp                 # Capture only TCP Packets
tcpdump -i eth0 port 22             # Capture Packet from Specific Port
tcpdump -i eth0 src 192.168.0.2     # Capture Packets from source IP
tcpdump -i eth0 dst 50.116.66.139   # Capture Packets from destination IP

DNS

dnsrecon Usage Example[7]

Scan a domain (-d example.com), use a dictionary to brute force hostnames (-D /usr/share/wordlists/dnsmap.txt), do a standard scan (-t std), and save the output to a file (–xml dnsrecon.xml)

nsrecon -d example.com -D /usr/share/wordlists/dnsmap.txt -t std --xml dnsrecon.xml

Ping scan grepable output [8]

# nmap -sn -oG - -iR 100
# Nmap 5.35DC18 scan initiated [time] as: nmap -sn -oG - -iR 5
Host: 93.182.218.153 () Status: Up
Host: 154.223.142.85 () Status: Down
Host: 120.128.8.97 ()   Status: Down
Host: 47.159.134.149 () Status: Down
Host: 24.172.4.19 ()    Status: Down
# Nmap done at [time] -- 5 IP addresses (1 host up) scanned in 4.25 seconds

VPN

Write PSK to a file[50]

ike-scan -M -A vpn ip -P file

DoS VPN SERVER

ike-scan -A -t 1 --sourceip= spoof ip dst ip
