WEP Cracking via Passive Listening
The purpose of this lab is to understand and exploit the security vulnerabilities of an 802.11 WEP-secured network. You will passively collected enough WEP IV's (Initialization Vectors) to determine the WEP encryption key. After obtaining the key, you will need to masquerade as a legitimate WEP client on the network, access a server, and download a file.

WEP Cracking via Active Injection
The purpose of this lab is to continue exploring the vulnerabilities of the 802.11 WEP security protocol. It is well-known that the WEP protocol is crippled with numerous security flaws. In the WEP Cracking via passive Listening lab in the Eureka series, we explored the methods of exploiting these flaws when a large amount of data was present. However, it is unlikely that a sufficiently large data stream is present on a network when in regular usage. This makes the relatively easy WEP crack from the Basic lab considerably more difficult. In this lab, we will use more efficient techniques to continue exploiting the WEP protocol.

WPA-PSK Key Cracking via Handshake Capture
The first generation of the IEEE 802.11 Wired Equivalent Privacy (WEP) security standard was found to be vulnerable to various statistical weaknesses in the encryption algorithm. While at- tempts were made to correct the problem, it is still relatively simple to crack WEP and essentially obtain the password right out of thin air. As a result, the Wi-Fi Alliance created an interim stan- dard called Wi-Fi Protected Access (WPA).
However, the WPA Pre-Shared Key (PSK) mode is crackable due to a flaw that exists in the au- thentication procedure. There is a human-friendly password and a user involved. Combined with the reality that most users select poor passwords, there is an opportunity that can be exploited. The TKIP cipher is not crackable, as it is a per-packet key. However, the initialization of the TKIP, which happens during client authentication, provides an opportunity to obtain the password.
An effective way to crack WPA-PSK is to force a re-authentication of a legitimate client. By forcing an actively connected client to disconnect and reconnect, we can capture the WPA-PSK four-way handshake that protects the key exchange. A robust dictionary attack may take care of a lot of simple passwords. Consequently, it is potentially easier to crack WPA-PSK than it is to crack WEP, as we will discover in this lab.

"Unlock" Wi-Fi Protected Setup (WPS)
Wi-Fi Protected Setup, or WPS, is a push-button authentication method for WPA2 Personal-secured networks. Have you ever been connecting to a network and seen an option underneath the ``Password" field that said ``Or push the button on the router to connect?" That is WPS at work. WPS relies mainly on physical security, or the idea that a potential attacker needs to be physically present to compromise the system. However, this lab will demonstrate how a remote WPS attack is still possible.

Mischievous MAC?
Carrier Sense Multiple Access (CSMA) is a probabilistic media access control (MAC) protocol in which a node verifies the absence of other traffic before transmitting on a shared transmission medium. CSMA/CA (Collision Avoidance) is a protocol for carrier transmission in 802.11 networks. In this lab, we will observe how traffic is regulated by CSMA/CA. With this knowledge, we can detect abuses and misbehavior targeted at CMA/CA at the MAC layer.

Evil Twin AP Attacks and Prevention
Evil twin is a malicious access point set up to copy the identity of a real access point, hence the name twin, in order to eavesdrop and steal sensitive information. This attack will trick unsuspected users to connect to it, and from there, the attacker can perform many other attacks like man-in- the-middle or phishing websites.

Identity Demystified
In cryptography, a public key certificate, also known as a digital certificate or identity certificate, is an electronic document used to prove the ownership of a public key. The certificate includes information about the key, information about the identity of its owner (called the subject), and the digital signature of an entity that has verified the certificate's contents (called the issuer). If the signature is valid, and the software examining the certificate trusts the issuer, then it can use that key to communicate securely with the certificate's subject.

Crypto Flickered!
Length extension attacks can cause serious vulnerabilities when people mistakenly try to construct something like an HMAC by using hash(secret || message)}. Many hash functions are subject to length extension. Such hash functions are built around a compression function and maintain an internal state, which is initialized to a fixed constant. Messages are processed in fixed-sized blocks by applying the compression function to the current state and current block to compute an updated internal state. The result of the final application of the compression function becomes the output of the hash function. A consequence of this design is that if we know the hash of an n-block message, we can find the hash of longer messages by applying the compression function for each block that we want to add. This process is called length extension, and it can be used to attack many applications of hash functions.

Bleeding Heart
The Heartbleed bug was a serious vulnerability in OpenSSL. The weakness allowed
attackers to steal information that would be protected in normal conditions by the SSL/TLS
encryption used to secure connections. The Heartbleed bug will take advantage of reading the
memory of the systems protected by the exploitable versions of OpenSSL. This compromises the
secret keys used to identify the service providers and to encrypt the traffic, the names and
passwords of the users and the actual content.

A “Leaky” Database
SQL injection is a code injection technique used to attack data-driven applications, in which malicious SQL statements are inserted into an entry field for execution. SQL injection must exploit a security vulnerability in an application's software, for example, when user input is either incorrectly filtered for string literal escape characters embedded in SQL statements or user input is not strongly typed and unexpectedly executed. SQL injection is mostly known as an attack vector for websites but can be used to attack any type of SQL database.

Video Aficionado
The purpose of this lab is to understand and exploit the vulnerabilities of ``open-access'' mobile data for privacy breaches. Typically, mobile devices such as smartphones have a set of rigorous access control mechanisms (e.g., formal permission requests to access personal information) to protect private or otherwise sensitive user data. As a result, these control mechanisms prohibit a third party (e.g., an app) from directly identifying private user information. However, not all mobile data is strictly prohibited for access, e.g., power consumption of a mobile device is considered to be non-sensitive. Subsequently, it is possible to infer private information from open-access data that is available to all apps.

WPA3-SAE: A Dragonfly Aims to Fix Wi-Fi’s Wings
In January 2018, WPA3 is announced to be a replacement to WPA2. The WPA3 standard replaces the pre-shared key (PSK) exchange with Simultaneous Authentication of Equals (SAE) as defined in IEEE 802.11-2016 resulting in a more secure initial key exchange in personal mode. It is also claimed that WPA3 will mitigate security issues posed by weak passwords and simplify the process of setting up devices with no display interface. However, just one year since the launch of WPA3 and researchers have unveiled several serious vulnerabilities in the wireless security protocol that could allow attackers to recover the password of the Wi-Fi network.

This Kerberos Never Sleeps
Kerberos is a network authentication protocol. It is designed to provide strong authentication for client/server applications by using secret-key cryptography. Kerberos works on the basis of tickets to allow nodes communicating over a non-secure network to prove their identity to one another in a secure manner. Its designers aimed it primarily at a client–server model, and it provides mutual authentication—both the user and the server verify each other's identity. Kerberos protocol messages are protected against eavesdropping and replay attacks.
