More about JSCEAL

The JSCEAL attack includes three main stages. First, victims are tricked into downloading a fake cryptocurrency app installer. Next, the malware runs scripts that collect detailed information about the system (e.g., installed programs, system settings, network info) and send it to the attackers.

If the target system is identified as worthwhile, the attackers install the final JSCEAL payload. This advanced malware is made to take full control of the infected computer and avoid detection by normal security programs. It also uses complicated code to hide its operations.

JSCEAL's primary goal is to steal sensitive information, especially related to cryptocurrency. It uses multiple techniques to achieve this, including gathering detailed machine and user data, collecting browser cookies, and stealing saved passwords. It also targets Telegram accounts, takes screenshots, and records keystrokes (keylogging).

Moreover, JSCEAL can manipulate cryptocurrency wallets and web extensions and perform advanced attacks to intercept and alter communications. This stealer also acts as a Remote Access Trojan (RAT), allowing attackers to run PowerShell commands remotely. It also has modules for mouse tracking and control to automate user interactions more effectively.

How did JSCEAL infiltrate my computer?

Users typically infect their computers with JSCEAL malware by downloading fake cryptocurrency applications promoted through deceptive online advertisements. These ads often mimic legitimate platforms (e.g., TradingView, Monero, or TrustWallet) and are presented using various websites and Facebook (or other social media channels).

Upon clicking the malicious ad, users are redirected to fraudulent sites that offer fake apps or browser extensions. During installation, the installer can open a window to show the website of the real app to prevent the victim from noticing anything suspicious.

Once downloaded and installed, these fake applications execute scripts that collect system information and prepare the device for the final payload. The final JSCEAL payload is then deployed, enabling the attackers to steal personal information and perform other malicious activities.

How to avoid installation of malware?

Download applications and files from official websites and do not trust pop-ups, ads, links, etc., on questionable web pages. Also, never download pirated programs or tools designed to bypass software activation. Do not agree to receive notifications from shady sites.

Update the operating system and installed apps regularly. Use a reliable security tool. Examine emails before interacting with their contents. Do not open files or links in unexpected or irrelevant emails (or other types of messages) from unknown senders. 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.
