Cybersecurity researchers have identified a new malware strain called VVS Stealer. This malware is written in Python and is designed to steal sensitive data from infected Windows systems. Its main focus is on Discord users, but it can also collect browser information. Experts say the threat is active and already being used by attackers.
VVS Stealer has been observed being sold on underground Telegram channels since at least April 2025. It is offered as a subscription-based tool, making it easy for cybercriminals to purchase and deploy. Because of its low price, even low-skill attackers can use it. This increases the risk of widespread abuse.
One of the main goals of this malware is to steal Discord authentication tokens. These tokens allow users to stay logged in without entering passwords. If an attacker steals a token, they can take over the account instantly. This makes Discord accounts especially vulnerable to this type of attack.
Apart from Discord data, VVS Stealer also targets web browsers. It can extract saved passwords, cookies, browsing history, and autofill data. The malware works against popular browsers based on Chromium as well as Firefox. This allows attackers to gain access to multiple online accounts from one infected system.
To avoid detection, VVS Stealer uses heavy code obfuscation with a tool known as PyArmor. This hides the real Python code and makes analysis difficult. Many traditional security tools struggle to detect such obfuscated scripts. As a result, the malware can remain active for longer periods without being noticed.
The malware also ensures persistence on infected machines. It adds itself to the Windows startup process so it runs every time the system boots. In some cases, it displays fake error messages to trick users into restarting their computers. This helps the malware stay active in the background.
VVS Stealer is also capable of performing Discord injection attacks. It stops the Discord application, downloads hidden JavaScript code, and manipulates active sessions. This allows attackers to hijack accounts even while users are logged in. Such techniques show a higher level of sophistication.
Security experts warn users to stay cautious and follow basic safety practices. Enabling multi-factor authentication on Discord can reduce account takeover risks. Avoid downloading files from unknown sources and keep systems updated. Awareness and timely protection remain the best defense against such threats.
Stay alert, and keep your security measures updated!
