# Check BSSIDs
|
|
|
|
When you receive a capture whose principal traffic is Wifi using WireShark you can start investigating all the SSIDs of the capture with _Wireless --> WLAN Traffic_:

## Brute Force
|
|
|
|
One of the columns of that screen indicates if **any authentication was found inside the pcap**. If that is the case you can try to Brute force it using `aircrack-ng`:
|
|
|
|
```bash
|
|
aircrack-ng -w pwds-file.txt -b <BSSID> file.pcap
|
|
```
|
|
|
|
For example it will retrieve the WPA passphrase protecting a PSK (pre shared-key), that will be required to decrypt the trafic later.

# Data in Beacons / Side Channel
|
|
|
|
If you suspect that **data is being leaked inside beacons of a Wifi network** you can check the beacons of the network using a filter like the following one: `wlan contains <NAMEofNETWORK>`, or `wlan.ssid == "NAMEofNETWORK"` search inside the filtered packets for suspicious strings.

# Find Unknown MAC Addresses in A Wifi Network
|
|
|
|
The following link will be useful to find the **machines sending data inside a Wifi Network**:
|
|
|
|
* `((wlan.ta == e8:de:27:16:70:c9) && !(wlan.fc == 0x8000)) && !(wlan.fc.type_subtype == 0x0005) && !(wlan.fc.type_subtype ==0x0004) && !(wlan.addr==ff:ff:ff:ff:ff:ff) && wlan.fc.type==2`
|
|
|
|
If you already know **MAC addresses you can remove them from the output** adding checks like this one: `&& !(wlan.addr==5c:51:88:31:a0:3b)`
|
|
|
|
Once you have detected **unknown MAC** addresses communicating inside the network you can use **filters** like the following one: `wlan.addr==<MAC address> && (ftp || http || ssh || telnet)` to filter its traffic. Note that ftp/http/ssh/telnet filters are useful if you have decrypted the traffic.
