New Satanstealer Malware Steals Browser Cookies and Passwords

A new malware named “Satanstealer” has been identified, targeting browser cookies and passwords.

The discovery was first reported by MonThreat, a prominent cybersecurity research group, via their official Twitter account.


The malware is designed to infiltrate users’ systems, extract sensitive information, and potentially compromise personal and financial data.

How Satanstealer Operates

Satanstealer operates by embedding itself within the victim’s system, often through phishing emails or malicious downloads.

Once installed, it scans the browser for stored cookies and passwords.

These cookies can contain session information, which allows the malware to hijack active sessions and gain unauthorized access to various online accounts.

The stolen passwords are then transmitted to the attackers’ servers, which can be used for further malicious activities or sold on the dark web.

MonThreat’s analysis indicates that Satanstealer is particularly sophisticated, employing advanced evasion techniques to avoid detection by traditional antivirus software.

This makes it a significant threat to both individual users and organizations.
