API Reference — Performing Kerberoasting Attack

Libraries Used

subprocess: Execute ldapsearch, PowerShell, Impacket GetUserSPNs, wevtutil
python-evtx: Parse Windows Security EVTX for Event ID 4769
xml.etree.ElementTree: Parse EVTX XML event data
impacket (external): GetUserSPNs.py for TGS ticket requests

CLI Interface

python agent.py enum --domain corp.example.com
python agent.py roast --domain corp.example.com [--user svc_account]
python agent.py analyze --file kerberoast_hashes.txt
python agent.py detect [--evtx security.evtx]

Core Functions

`enumerate_spn_accounts(domain)` — Find SPN-enabled accounts

LDAP query for (servicePrincipalName=*). Falls back to PowerShell Get-ADUser. Identifies high-value targets with admin group membership.

`request_tgs_tickets(domain, username)` — Execute Kerberoasting

Uses Impacket GetUserSPNs with -request flag. Outputs krb5tgs hashes.

`analyze_kerberoast_hashes(hash_file)` — Assess hash crackability

Categorizes by encryption type: RC4 (etype 23, crackable) vs AES (etype 17/18).

`detect_kerberoasting(evtx_file)` — Detect attack via Event ID 4769

Flags TGS requests with RC4 encryption (0x17) as suspicious Kerberoasting indicators.

Encryption Types

Etype	Algorithm	Crackability
0x17 (23)	RC4-HMAC	HIGH — fast offline cracking
0x11 (17)	AES128	LOW — computationally expensive
0x12 (18)	AES256	LOW — computationally expensive

Dependencies

pip install impacket python-evtx

System: ldapsearch (optional), PowerShell with AD module (Windows)
