por An Evil Twin attack is an attack technique on wireless networks where an attacker creates a fake access point that appears to be legitimate, but is designed to trick users and steal their personal information.
In this post, we will see in depth what the Evil Twin attack consists of.
What is the Evil Twin attack?
The Evil Twin attack is a type of attack in which the attacker configures a Wi-Fi access point with the same name (SSID) and appearance as a legitimate network that users are accustomed to connecting to, such as a public Wi-Fi network or the a company’s wireless network. The goal is to make users connect to the fake access point instead of the legitimate network.
Once users connect to the malicious access point, the attacker can perform several harmful actions. This can include stealing sensitive information, such as passwords, login details, or banking information, as well as conducting man-in-the-middle attacks (man-in-the-middle) to intercept and manipulate network traffic.
How does the Evil Twin attack work?
Evil Twin attack generally follows the following steps:
Network scanning. The attacker scans for available wireless networks in the target area. This can be done using tools such as the monitoring mode of a wireless network card or software specific.
Creation of the fake access point. Once the target network is identified, the attacker sets up a fake wireless access point with the same name as the legitimate network (SSID) or a similar name that can fool users. The fake access point is configured to imitate all the features of the original network, such as encryption and authentication type.
Credential capture. When users connect to the fake access point, the attacker can capture the credentials they enter, such as usernames and passwords, using techniques such as phishing.
Traffic interception. When users are already connected to the fake access point, the attacker can perform man-in-the-middle attacks (man-in-the-middle) to intercept and manipulate network traffic. This can allow the attacker to eavesdrop on communication between users and servers; In this way, you could steal confidential information.
Additional attacks. These may include malicious code injection, redirection to fake websites, session hijacking, or distribution of malware.
What range does the Evil Twin attack have?
The Evil Twin attack relies on tricking users into connecting to a fake Wi-Fi hotspot that appears to be legitimate. When users connect to the fake access point, the attacker can perform different harmful actions, such as:
Intercept traffic. As we have mentioned before, the attacker can perform a man-in-the-middle attack (man-in-the-middle) to intercept and view all network traffic passing through the fake access point. This includes sensitive data such as passwords, login information, banking details, and any other information that users transmit unencrypted.
Website impersonation. The attacker in the Evil Twin attack can set up fake web pages that imitate legitimate websites, such as login pages for social networks, banks, or popular online services. When users try to access these sites through the fake access point, the attacker collects their login credentials.
Code injection attacks. The attacker can modify network traffic to inject malicious code into web pages that users visit. This may include inserting scripts malicious that steal information or redirect to fake sites.
Denial of service. In the Evil Twin attack, denial of service attacks can be performed to overwhelm the legitimate network or access point, making it difficult or impossible for users to connect to the legitimate network.
