How Does Evilginx2 Work? Explained
Evilginx2 is a man-in-the-middle (MITM) framework used for phishing and proxying HTTP traffic. It is designed to bypass two-factor authentication (2FA) and other security measures, allowing attackers to access sensitive information without being detected. In this explanation, we will delve into the inner workings of Evilginx2, its components, and how it operates.
Overview of Evilginx2
Evilginx2 is an open-source tool written in Go, making it highly portable and efficient. It is primarily used for phishing campaigns, where attackers aim to trick victims into revealing their login credentials or other sensitive data. The framework consists of several components, including a phishing server, a proxy server, and a configuration module.
Components of Evilginx2
The main components of Evilginx2 are:
- Phishing Server: This component is responsible for hosting the phishing website, which mimics the legitimate website of the target service. The phishing server is configured to capture user input, such as login credentials, and forward it to the attacker.
- Proxy Server: The proxy server acts as an intermediary between the victim’s browser and the legitimate website. It intercepts and modifies HTTP requests and responses, allowing the attacker to inject malicious code or steal sensitive data.
- Configuration Module: This module is used to configure the phishing server and proxy server. It allows attackers to customize the phishing campaign, including setting up the target website, configuring proxy settings, and specifying the type of data to be captured.
How Evilginx2 Works
The operation of Evilginx2 involves several steps:
- The attacker sets up the phishing server and configures the proxy server to target a specific website.
- The victim receives a phishing email or message with a link to the phishing website.
- When the victim clicks on the link, they are redirected to the phishing website, which appears identical to the legitimate website.
- The victim enters their login credentials, which are captured by the phishing server and forwarded to the attacker.
- The proxy server intercepts the HTTP requests and responses between the victim’s browser and the legitimate website, allowing the attacker to inject malicious code or steal sensitive data.
- The attacker can then use the stolen credentials to access the victim’s account, bypassing 2FA and other security measures.
Technical Details
Evilginx2 uses several techniques to bypass security measures, including:
- HTTP request manipulation: The proxy server modifies HTTP requests to inject malicious code or steal sensitive data.
- SSL stripping: The proxy server downgrades HTTPS connections to HTTP, allowing the attacker to intercept sensitive data.
- Cookie manipulation: The proxy server modifies cookies to bypass security measures, such as 2FA.
Component | Functionality |

Phishing Server | Hosts the phishing website and captures user input |
Proxy Server | Intercepts and modifies HTTP requests and responses |
Configuration Module | Configures the phishing server and proxy server |
Defense Against Evilginx2
To defend against Evilginx2 and similar phishing attacks, it is essential to implement robust security measures, including:
- 2FA: Enable 2FA for all sensitive accounts to prevent attackers from accessing them using stolen credentials.
- HTTPS: Use HTTPS for all web traffic to prevent eavesdropping and tampering.
- Phishing detection: Implement phishing detection tools and educate users about phishing attacks and how to identify them.
- Regular updates: Keep all software and systems up-to-date with the latest security patches to prevent exploitation of known vulnerabilities.
