API Reference — Performing Active Directory Forest Trust Attack

Libraries Used

impacket: SMB/RPC transport for LSA SID lookups via lsat.hLsarLookupSids2()
ldap3: LDAP queries against trustedDomain objects and foreignSecurityPrincipal containers
json: JSON serialization for audit reports

CLI Interface

python agent.py --dc 10.0.0.1 --domain corp.local --username admin --password Pass123 trusts
python agent.py --dc 10.0.0.1 --domain corp.local --username admin --password Pass123 foreign
python agent.py --dc 10.0.0.1 --domain corp.local --username admin --password Pass123 lookup-sid --sid S-1-5-21-...
python agent.py --dc 10.0.0.1 --domain corp.local --username admin --password Pass123 full

Core Functions

`enumerate_trusts_ldap(dc_host, domain, username, password)` — Trust enumeration

LDAP search: (objectClass=trustedDomain) under CN=System,DC=.... Attributes: trustPartner, trustDirection, trustType, trustAttributes, flatName. Decodes trust attribute bitmask for SID filtering, forest transitivity, RC4 encryption.

`enumerate_foreign_principals(dc_host, domain, username, password)` — Cross-forest members

LDAP search: (objectClass=foreignSecurityPrincipal) under CN=ForeignSecurityPrincipals. Filters well-known SIDs (S-1-5-x with 3 dashes). Returns group memberships.

`lookup_sid_cross_forest(dc_host, domain, username, password, target_sid)` — LSA SID resolution

Opens SMB transport to \lsarpc, binds MSRPC_UUID_LSAT, calls hLsarLookupSids2(). Resolves SIDs across trust boundaries.

`assess_trust_risk(trusts, foreign_principals)` — Risk scoring

Scoring: +40 SID filtering disabled, +20 RC4 encryption, +15 bidirectional trust, +10 forest transitive.

`full_audit(dc_host, domain, username, password)` — Comprehensive audit

Trust Direction Values

Value	Direction
0	Disabled
1	Inbound
2	Outbound
3	Bidirectional

Trust Attribute Flags

Flag	Hex	Description
NON_TRANSITIVE	0x01	Trust does not extend transitively
QUARANTINED_DOMAIN	0x04	SID filtering enabled
FOREST_TRANSITIVE	0x08	Forest-wide transitive trust
USES_RC4_ENCRYPTION	0x80	RC4 trust key (weaker than AES)

Impacket RPC Calls

Call	Module	Purpose
`hLsarOpenPolicy2`	lsad	Open LSA policy handle
`hLsarLookupSids2`	lsat	Resolve SIDs to names across trust
SMBTransport(`\lsarpc`)	transport	RPC transport over SMB

Dependencies

impacket >= 0.11.0
ldap3 >= 2.9.0
Network access to DC ports 389 (LDAP), 445 (SMB), 88 (Kerberos)
