### Overview of Relative Identifiers (RID) and Security Identifiers (SID)
|
|
|
|
**Relative Identifiers (RID)** and **Security Identifiers (SID)** are key components in Windows operating systems for uniquely identifying and managing objects, such as users and groups, within a network domain.
|
|
|
|
- **SIDs** serve as unique identifiers for domains, ensuring that each domain is distinguishable.
|
|
- **RIDs** are appended to SIDs to create unique identifiers for objects within those domains. This combination allows for precise tracking and management of object permissions and access controls.
|
|
|
|
For instance, a user named `pepe` might have a unique identifier combining the domain's SID with his specific RID, represented in both hexadecimal (`0x457`) and decimal (`1111`) formats. This results in a complete and unique identifier for pepe within the domain like: `S-1-5-21-1074507654-1937615267-42093643874-1111`.
|
|
|
|
|
|
### **Enumeration with rpcclient**
|
|
|
|
The **`rpcclient`** utility from Samba is utilized for interacting with **RPC endpoints through named pipes**. Below commands that can be issued to the SAMR, LSARPC, and LSARPC-DS interfaces after a **SMB session is established**, often necessitating credentials.
|
|
|
|
#### Server Information
|
|
|
|
* To obtain **Server Information**: `srvinfo` command is used.
|
|
|
|
#### Enumeration of Users
|
|
|
|
* **Users can be listed** using: `querydispinfo` and `enumdomusers`.
|
|
* **Details of a user** by: `queryuser <0xrid>`.
|
|
* **Groups of a user** with: `queryusergroups <0xrid>`.
|
|
* **A user's SID is retrieved** through: `lookupnames <username>`.
|
|
* **Aliases of users** by: `queryuseraliases [builtin|domain] <sid>`.
|
|
|
|
```bash
|
|
# Users' RIDs-forced
|
|
for i in $(seq 500 1100); do
|
|
rpcclient -N -U "" [IP_ADDRESS] -c "queryuser 0x$(printf '%x\n' $i)" | grep "User Name\|user_rid\|group_rid" && echo "";
|
|
done
|
|
|
|
# samrdump.py can also serve this purpose
|
|
```
|
|
|
|
#### Enumeration of Groups
|
|
|
|
* **Groups** by: `enumdomgroups`.
|
|
* **Details of a group** with: `querygroup <0xrid>`.
|
|
* **Members of a group** through: `querygroupmem <0xrid>`.
|
|
|
|
#### Enumeration of Alias Groups
|
|
|
|
* **Alias groups** by: `enumalsgroups <builtin|domain>`.
|
|
* **Members of an alias group** with: `queryaliasmem builtin|domain <0xrid>`.
|
|
|
|
#### Enumeration of Domains
|
|
|
|
* **Domains** using: `enumdomains`.
|
|
* **A domain's SID is retrieved** through: `lsaquery`.
|
|
* **Domain information is obtained** by: `querydominfo`.
|
|
|
|
#### Enumeration of Shares
|
|
|
|
* **All available shares** by: `netshareenumall`.
|
|
* **Information about a specific share is fetched** with: `netsharegetinfo <share>`.
|
|
|
|
#### Additional Operations with SIDs
|
|
|
|
* **SIDs by name** using: `lookupnames <username>`.
|
|
* **More SIDs** through: `lsaenumsid`.
|
|
* **RID cycling to check more SIDs** is performed by: `lookupsids <sid>`.
|
|
|
|
