The course covers the theory and practice of wireless penetration testing, from the basics of IEEE 802.11 standards and protocols, to the advanced techniques of sniffing, cracking, injecting, bypassing, disrupting, intercepting, and creating wireless attacks. You will learn how to use tools such as Aircrack-ng, Wireshark, Kismet, Metasploit, Scapy, Ettercap, Airbase-ng, MDK3, and more.


The course also prepares you for the Offensive Security Wireless Professional (OSWP) certification exam, which is a practical exam that tests your ability to perform wireless attacks in a real-world scenario. The exam requires you to compromise several wireless networks using different methods and tools within a four-hour time limit.


Why learn Offensive Security Wifu?




Wireless networks are ubiquitous in today's world, but they also pose significant security risks. Many wireless devices and access points are configured with weak or default settings, or use outdated or flawed encryption schemes. This makes them vulnerable to various attacks that can compromise their confidentiality, integrity, or availability.


By learning Offensive Security Wifu, you will be able to:


  • Understand how wireless networks work and how they can be attacked



  • Detect and analyze wireless traffic using various tools



  • Crack different types of wireless encryption keys



  • Bypass wireless authentication mechanisms



  • Inject frames into wireless networks to manipulate or disrupt them



  • Perform man-in-the-middle attacks on wireless networks



  • Create rogue access points and honeypots to lure or trap unsuspecting users



  • Demonstrate your skills and knowledge by passing the OSWP exam



  • Enhance your career prospects as a wireless penetration tester or security professional
