Review: Deauther OLED Mini by DSTIKE

Paranoid with wireless cameras hidden in the Airbnb? Or the ability to disable your roommate's Netflix stream. The WiFi Deauther OLED MINI is the next leap forward of the Deauther series by DSTIKE, a low-cost WiFi deauthentication project that originates from Spacehuhn.





Hardware-wise, the MINI boasts only ~80mA of power usage, with an extremely compact board design of only 68mm x 28mm. For the user, a SH1106 1.3" OLED display and tactile switch provides basic menu control, while power relies upon a common micro-USB cable.

From the official store site:

  • Only ~80mA power usage
  • LM39100 Low Voltage Low-Dropout Regulator
  • TP4056+PL5353A battery protection solution
  • Included 2dB antenna
  • All GPIO breakouts and 3.3 and 5V output
  • 2 LEDs to indicate battery charging status (Red:Charging,Green:Full)
  • Protection: short, over charging, over discharging, temperature


On the software side, the MINI comes pre-installed with the latest ESP8266 Deauther software to perform different attacks on WiFi networks. From boot-up, the menu will display the following: SCAN, SELECT, ATTACK, PACKET MONITOR and LED.
For a common 'deauth' attack, you will need follow the steps bellow:

1. Select 'SCAN' and 'SCAN AP + ST'
2. Wait for the Scan to be completed and then select the AP's and Stations in the 'SELECT' menu that you want to attack.
3. Select the 'ATTACK' menu and select the 'DEAUTH' option.
4. Initialize the attack by selecting 'START' and stopping the attack with 'STOP'.





There are three main functions of the MINI,
Deauth:
Closes the connection of WiFi devices by sending deauthentication frames to access points and client devices you selected.

Beacon:
Beacon packets are used to advertise access points. By continuously sending beacon packets out, it will look like you created new WiFi networks.

Probe:
Probe requests are sent by client devices to ask if a known network is nearby.
Use this attack to confuse WiFi trackers by asking for networks that you specified in the SSID list.


Wifi Jammer vs Deauther
A jammer creates noise and overloads the communication between devices, being harder to acquire than the Deauther due to its specialist hardware. On the other hand, a Deauther can be derived from a range of equipment such as laptops, or a cheap module with a Wifi-chip that supports packet injection. The Deauther relies on the unencrypted management frames of Wifi to trick the targeted device to terminate connection with its access point. Finally, the biggest difference lies in the Deauther's ability to target 'Stations' and 'Access points', while the jammer will block everything in a given radius.
