{% endhint %} ## **Password Spraying** Sodra jy verskeie **geldige gebruikersname** gevind het, kan jy die mees **gewone wagwoorde** probeer (hou in gedagte die wagwoordbeleid van die omgewing) met elkeen van die ontdekte gebruikers.\ Deur **standaard** is die **minimum** **wagwoord** **lengte** **7**. Lys van algemene gebruikersname kan ook nuttig wees: [https://github.com/insidetrust/statistically-likely-usernames](https://github.com/insidetrust/statistically-likely-usernames) Let daarop dat jy **sekere rekeninge kan sluit as jy verskeie verkeerde wagwoorde probeer** (deur standaard meer as 10). ### Kry wagwoordbeleid As jy 'n paar gebruikersakkrediteer of 'n shell as 'n domein gebruiker het, kan jy **die wagwoordbeleid kry met**: ```bash # From Linux crackmapexec -u 'user' -p 'password' --pass-pol enum4linux -u 'username' -p 'password' -P rpcclient -U "" -N 10.10.10.10;
