Myth Stealer

What kind of malware is Myth?

Myth is an information stealer written in Rust programming language. The stealer is designed to target browsers built on both Gecko and Chromium engines, stealing sensitive data such as passwords, cookies, and autofill details. It also employs anti-analysis measures, including string obfuscation and system checks based on filenames and usernames.

More about Myth stealer

Before executing its main functions, the stealer checks whether it is running in a sandbox environment by looking for certain usernames and file names. If it detects any indicators of a virtual or test environment, it shuts down to avoid analysis.

Additionally, the malware forcibly closes several web browser processes if they are active, including popular browsers like Chrome, Firefox, Edge, and others. Myth stealer extracts sensitive user data from applications like Discord, Chrome, and others, including stored passwords, browser cookies, autofill data, and saved credit card details.

Furthermore, the stealer monitors the system clipboard to detect cryptocurrency transactions. When a user copies a wallet address, the malware replaces it with the attacker's wallet address, redirecting any funds the victim sends. This technique is known as clipboard hijacking. Also, Myth can capture screenshots.

After collecting user data, the malware packages the information into a compressed file and sends it to a remote command and control (C2) server. To stay active on the computer, the stealer makes a copy of itself and saves it in the user's AppData folder. It also creates a shortcut file in the system's Startup folder, which runs automatically every time the computer starts.

How did Myth infiltrate my computer?

Users can become infected with this malware by downloading it from fake gaming websites that disguise the malicious software as game-related files. The malware is often delivered in password-protected RAR archives, ZIP files containing instructions, or standalone executable files.

Sometimes, attackers promote the malware on online forums, pretending it is cheat software and even providing fake virus scan results to appear trustworthy. After the user runs the downloaded file, a fake window appears to make them believe a legitimate program is running, while in the background, the malware decrypts and installs the harmful stealer on the system.

How to avoid installation of malware?

Be careful with emails, like those from unfamiliar sources or ones you did not expect. Do not open attachments or click on links in suspicious emails. Always get software from official sites or reputable app stores, and steer clear of pirated software, keygens, and cracking tools.

Regularly update your operating system and apps to protect against security flaws. Do not interact with ads, pop-ups, and links on questionable websites, and avoid allowing notifications from them. Also, run frequent scans with reliable antivirus or security software to keep your system secure.

If you believe that your computer is already infected, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate infiltrated malware.
