Permission Groups Discovery `T1069`

Adversaries may attempt to discover group and permission settings. This information can help adversaries determine which user accounts and groups are available, the membership of users in particular groups, and which users and groups have elevated permissions.

Events covered

5 catalog events are tagged with this technique by at least one rule.

Provider	Event ID	Title
Sysmon	1	Process creation
Security-Auditing	4662	An operation was performed on an object.
Security-Auditing	4688	A new process has been created.
PowerShell	4103	Payload Context: ContextInfo User Data: UserData.
PowerShell	4104	Creating Scriptblock text (MessageNumber of MessageTotal).

Authoring guide

Patterns shared across the 5 rules above: which fields they filter on, what specific values they look for, and what they exclude. Field names are normalized across vendors so Sigma's Image, Elastic's process.name, and Splunk's process_name collapse into one row. Each rule contributes at most once per row.

Fields filtered most (5 distinct)

The fields most rules look at when detecting this technique. The How column shows the operators authors use (eq, wildcard, regex_match, match) and how often each appears. Sample values are concrete examples to start from, not an exhaustive list.

Field	Rules	How	Sample values
`ScriptBlockText`	2	`match` 1, `eq` 1	`Invoke-SauronEye`, `Get-FoxDump`, `Invoke-KrbRelay`, `Get-DomainObjectAcl`, `get-objectacl`
`AccessMaskDescription`	1	`eq` 1	`Read Property`
`Payload`	1	`match` 1	`Get-MachineAccountCreator`, `Invoke-SauronEye`, `Get-FoxDump`
`CommandLine`	1	`match` 1	`Get-MachineAccountCreator`, `Invoke-SauronEye`, `Get-FoxDump`
`EventID`	1	`eq` 1	`4104`

Top indicator values (574 distinct)

Specific (field, operator, value) combinations the rules check for, ranked by how many rules under this technique use each one. The Corpus reach column counts how many rules across the entire catalog (any technique) check the same combination. High numbers point to widely-used indicators that are likely noisy on their own; combine them with another condition for useful signal. Blank means the combination is specific to rules under this technique.

Field	Kind	Value	Rules (here)
`AccessMaskDescription`	`eq`	`Read Property`	1
`Payload`	`match`	`Invoke-Tater`	1
`Payload`	`match`	`Invoke-ShadowSpray`	1
`Payload`	`match`	`Invoke-ADRecon`	1
`Payload`	`match`	`Port-Scan`	1
`Payload`	`match`	`Get-MachineAccountCreator`	1
`Payload`	`match`	`Invoke-Tokenvator`	1
`Payload`	`match`	`Invoke-Get-RBCD-Threaded`	1
`Payload`	`match`	`Invoke-MITM6`	1
`Payload`	`match`	`Invoke-OfficeScrape`	1
`Payload`	`match`	`New-HoneyHash`	1
`Payload`	`match`	`Invoke-ADSBackdoor`	1
`Payload`	`match`	`Invoke-Seatbelt`	1
`Payload`	`match`	`Invoke-AgentSmith`	1
`Payload`	`match`	`Invoke-BackdoorLNK`	1
`Payload`	`match`	`Invoke-WireTap`	1
`Payload`	`match`	`Export-ADRHTML`	1
`Payload`	`match`	`Invoke-Snaffler`	1
`Payload`	`match`	`Show-TargetScreen`	1
`Payload`	`match`	`Invoke-ARPScan`	1

Common exclusions (1 distinct)

Field/operator/value combinations that rules under this technique routinely exclude (top-level not() clauses). These are the false-positive paths the community has learned to filter out. A new rule that ignores the high-count entries here will likely fire on the same noisy paths.

Field	Kind	Value	Rules excluding
`SubjectUserSid`	`eq`	`S-1-5-18`	1
