A tester is performing an external phishing assessment on the top executives at a company.

To bypass two-factor authentication (2FA) and gain access to the executives’ accounts, the tester should use Evilginx with a typosquatting domain. Evilginx is a man-in-the-middle attack framework used to bypass 2FA by capturing session tokens.

Phishing with Evilginx:

Evilginx is designed to proxy legitimate login pages, capturing credentials and 2FA tokens in the process.

It uses "phishlets" which are configurations that simulate real login portals.

Typosquatting:

Typosquatting involves registering domains that are misspelled versions of legitimate domains (e.g., example.co instead of example.com).

This technique tricks users into visiting the malicious domain, thinking it's legitimate.

Steps:

Configure an External Domain: Register a typosquatting domain similar to the company’s domain.

Set Up Evilginx: Install and configure Evilginx on a server. Use a phishlet that mimics the company's mail portal.

Send Phishing Emails: Craft phishing emails targeting the executives, directing them to the typosquatting domain.

Capture Credentials and 2FA Tokens: When executives log in, Evilginx captures their credentials and session tokens, effectively bypassing 2FA.

Using Evilginx with a typosquatting domain allows the tester to bypass 2FA and gain access to high-value accounts, demonstrating the effectiveness of advanced phishing techniques.
