  • Can be used For Satellite Communication For Hacking by using External Satellite Antenna With SDR
  • Receiving Decoded Data Over Radio Frequency

4. WIFI Pineapple Mark VII

This hacking tool is from Hak5. It’s a WIFI Pentesting platform that is widely respected. It can automate pentest and provide you with in-depth reports. Interactive recon puts you in command of the airspace, and a complement of dedicated radios provides enterprise-grade results. 


It will cost you around $100

Primary Uses and Applications

  • Perform advanced man-in-the-middle attacks by thoroughly mimicking preferred networks
  • Gather intelligence, including what other networks the targets have connected
  • Completely visualizes the WiFi landscape with continuous, live passive monitoring
  • Capture WPA and WPA Enterprise credentials in pcap, hashcat, JTR, or plaintext formats

5. Alfa AC1900 wifi adapter

Well, this is not your standard external network wifi adaptor. You can do a lot more with it in conjunction with the likes of Kali Linux. It supports monitoring, packet injection, and managed mode and can be connected with external antenna connectors.

You may like to go with two of them as that will be required for some of the Pentests/attacks. It works well with Debian OS and with virtual environments.


It’s reasonably priced for around $65.


  • Standards: IEEE 802.11ac/a/n/g/b
  • Interface: USB 3.0

6. On-Board Diagnostics (ODB2) adapter

Modern vehicles use different communication protocols which are incompatible with standard protocols like RS-232, USB, and so on. Using the ODB2 Adapter, you can connect to the car computer and send and receive controls.

This is one of the core hacking tools for Vehicles and is similar in operation to a computer modem or a gateway, in that it translates messages from one protocol to another.

Embedded computer systems in vehicles typically support the following functions:

  • Regulate fuel injectors.
  • Control the spark plugs.
  • Adapt the idle speed
  • Notify the driver of a problem with the “Check Engine” light
  • Monitor the ignition system.
  • Deliver electrical commands to the transmission and camshaft systems.


Depending on the OEM, it may cost you between $50 to $100.


It May differ for different manufacturers
