Quick start cypher queries

To help you get started, here are a set of quick start cypher queries for the most common needs:

Find principals with Full control access to a share

The following query will allow you to find principals with full control access to a share

MATCH (p:Principal)-[r]->(s:NetworkShareSMB)
WHERE (p)-[:CanDelete]->(s)
  AND (p)-[:CanDsControlAccess]->(s)
  AND (p)-[:CanDsCreateChild]->(s)
  AND (p)-[:CanDsDeleteChild]->(s)
  AND (p)-[:CanDsDeleteTree]->(s)
  AND (p)-[:CanDsListContents]->(s)
  AND (p)-[:CanDsListObject]->(s)
  AND (p)-[:CanDsReadProperty]->(s)
  AND (p)-[:CanDsWriteExtendedProperties]->(s)
  AND (p)-[:CanDsWriteProperty]->(s)
  AND (p)-[:CanReadControl]->(s)
  AND (p)-[:CanWriteDacl]->(s)
  AND (p)-[:CanWriteOwner]->(s)
RETURN p,r,s

This will result in a graph similar to this one (I like to call it the Full Control Onion):

graph LR
    S-1-5-21-3797563538-650367887-713497691-1106[S-1-5-21-3797563538-650367887-713497691-1106] -->| CanDelete | ExampleShare[ExampleShare]

Find principals with Write access to a share

The following query will allow you to find files by name (case insensitive)

MATCH x=(p:Principal)-[r:CanWriteDacl|CanWriteOwner|CanDsWriteProperty|CanDsWriteExtendedProperties]->(s:NetworkShareSMB)
RETURN x 

This will result in a graph similar to this one:

graph LR
    S-1-5-21-3797563538-650367887-713497691-1106[S-1-5-21-3797563538-650367887-713497691-1106] -->| CanWriteDacl | ExampleShare[ExampleShare]
    S-1-5-21-3797563538-650367887-713497691-1106 -->| CanWriteOwner | ExampleShare
    S-1-5-32-544[S-1-5-32-544] -->| CanWriteDacl | SYSVOL[SYSVOL]
    S-1-5-32-544 -->| CanWriteOwner | SYSVOL
    S-1-5-32-544 -->| CanWriteDacl | ExampleShare
    S-1-5-32-544 -->| CanWriteOwner | ExampleShare

Find files by name (case insensitive)

The following query will allow you to find files by name (case insensitive)

MATCH p=(h:NetworkShareHost)-[:HasNetworkShare]->(s:NetworkShareSMB)-[:Contains*0..]->(f:File)
WHERE toLower(f.name) = toLower("flag.txt")
RETURN p

This will result in a graph similar to this one:

graph LR
    DC01[DC01] -->| HasNetworkShare | Test[Test]
    Test -->| Contains | Dir1[Dir1]
    Test -->| Contains | DirA[DirA]
    DirA -->| Contains | flag.txtA[flag.txt]
    Dir1 -->| Contains | Dir2[Dir2]
    Dir2 -->| Contains | flag.txt1[flag.txt]

Find files by extension (case insensitive)

The following query will allow you to find files by extension (case insensitive)

MATCH p=(h:NetworkShareHost)-[:HasNetworkShare]->(s:NetworkShareSMB)-[:Contains*0..]->(f:File)
WHERE toLower(f.extension) = toLower(".vmdk")
RETURN p

This will result in a graph similar to this one:

graph LR
    DC01[DC01] -->| HasNetworkShare | Test[Test]
    Test -->| Contains | Dir1[Dir1]
    Test -->| Contains | DirA[DirA]
    DirA -->| Contains | SRV02.vmdkA[SRV02.vmdk]
    Dir1 -->| Contains | Dir2[Dir2]
    Dir2 -->| Contains | DC01.vmdk1[DC01.vmdk]

Find files by extension (case insensitive)

The following query will allow you to find files by name (case insensitive)

MATCH p=(h:NetworkShareHost)-[:HasNetworkShare]->(s:NetworkShareSMB)-[:Contains*0..]->(f:File)
WHERE toLower(f.name) ENDS WITH ".bat"
RETURN p

This will result in a graph similar to this one:

graph LR
    DC01[DC01] -->| HasNetworkShare | Test[Test]
    Test -->| Contains | Dir1[Dir1]
    Test -->| Contains | DirA[DirA]
    DirA -->| Contains | script.batA[script.bat]
    Dir1 -->| Contains | Dir2[Dir2]
    Dir2 -->| Contains | logon.bat1[logon.bat]

For advanced users

All node types and edges name are defined in the kinds.py file, so that you can easily find the name of these to create custom Cypher queries.
