Wi-Fi Network Defense
WiFi networks are prime targets for cyberattacks due to their wireless nature. Effective WiFi network defense involves implementing strong encryption, secure authentication, network monitoring, and intrusion prevention to protect against unauthorized access, eavesdropping, and attacks like Evil Twin, Man-in-the-Middle (MitM), and Packet Sniffing.
In the heart of the technologically advanced city of Nexburg, a shadowy organization known as TechNet is preparing to execute a series of covert cyber operations. Their objective? To infiltrate and exfiltrate highly sensitive data by exploiting vulnerabilities in the city's vast WiFi networks. Using sophisticated encryption techniques and stealthy cyber tactics, TechNet aims to remain undetected as they breach high-value targets, including government institutions, corporate servers, and personal communications.
However, their activities have not gone unnoticed. A highly skilled cybersecurity force known as the WiFi Defenders has detected unusual spikes in network traffic, rogue access points, and encrypted transmissions flowing through Nexburg’s wireless infrastructure. Armed with cutting-edge tools and advanced cyber forensic techniques, the WiFi Defenders are in a race against time to track down TechNet’s operatives, analyze intercepted signals, and neutralize cyber threats before catastrophic breaches occur.
As one of the elite members of the WiFi Defenders, your mission is clear: trace TechNet’s digital footprints, uncover their hidden command centers, and dismantle their operations before they can execute their plans. The battle for control over Nexburg’s digital lifelines has begun.
Will you be able to secure the city’s wireless networks before it's too late?
TechNet has been actively probing the WiFi networks in Nexburg, trying to identify all available networks. You’ve intercepted a suspicious capture from their reconnaissance. Your job is to uncover all the hidden networks they are targeting.
TechNet has successfully infiltrated a WiFi network in Nexburg and now has the encrypted WPA2 handshake of the network. Your task is to capture the handshake and crack the password to access the network.
Goal: Extract a secret message from beacon frames.
Story:
TechNet is trying to exfiltrate sensitive data through beacon frames. They’ve hidden the secret message within the SSID of several beacon frames. As a WiFi Defender, it’s up to you to find and extract the hidden message.
Goal: Extract a hidden message sent over beacon frames.
Story:
TechNet has taken their data exfiltration to the next level. This time, they’ve encoded a secret flag in the SSID of beacon frames sent over the network. You’ll need to carefully capture the frames and reconstruct the hidden flag.
Goal: Detect a denial-of-service (DoS) attack from a PCAP file.
Story:
TechNet has launched a deauthentication flood attack in an attempt to disrupt WiFi networks across Nexburg. You’ve intercepted the attack, but now you need to analyze the captured traffic and determine how many deauthentication packets were sent during the attack..
As the WiFi Defenders, you’ve successfully thwarted TechNet’s attempts to compromise the city’s wireless networks. With each challenge, you’ve unraveled their covert operations, stopped their exfiltration attempts, and cracked their encrypted passwords. You are the unsung heroes of Nexburg’s cybersecurity, ensuring the city’s WiFi infrastructure stays secure.
Now, it’s time to rest, for the next wave of challenges might just be around the corner…
