Threat Intel FAQ

Can MFA protect against VEGA Stealer?

While MFA is a crucial security layer, it is not a complete shield against info-stealers. VEGA Stealer targets session cookies, which are stored locally on the browser. If an attacker successfully exfiltrates these cookies, they can import them to perform session hijacking, which allows them to bypass the login process entirely by masquerading as an already-authenticated session.

How can my company verify if we are affected by VEGA Stealer?

The first step is to perform a comprehensive sweep of your enterprise environment for indicators of compromise. Additionally, utilizing an external assessment tool like FemtoSec's Dark Web Scanner allows you to check for recent mentions, log signals, and compromised credentials associated with your domain, providing an immediate snapshot of your exposure risk.
