How to remove OmniStealer from infected devices

What kind of malware is OmniStealer?

OmniStealer is an information stealer targeting cryptocurrency wallets, web browsers, and other applications (and accounts). It is commonly delivered using GitHub repositories. Victims of OmniStealer attacks can encounter issues such as identity theft, financial loss, account hijacking, reputational damage, or other negative outcomes.

More about OmniStealer

OmniStealer can steal saved browser logins (usernames and passwords) and password manager data (e.g., vault contents from tools like LastPass). It targets over ten password managers. The stealer can also grab session tokens, autofill data, and cookies from popular web browsers (targeted browsers include Chrome and Firefox).

Furthermore, OmniStealer can grab crypto wallet data from more than sixty browser extensions (e.g., MetaMask, Coinbase Wallet). This information likely includes private keys or seed-related information. It also targets Cloud storage credentials (e.g., Google Drive accounts). This can expose personal documents, backups, and other information.

OmniStealer can lead to account takeovers, as stolen passwords and session tokens allow cybercriminals to access email, social media, gaming, banking, or other accounts. It can cause financial losses, especially if cryptocurrency wallets are compromised, since those transactions are irreversible. Victims may also suffer identity theft and reputational damage.

It is important to note that roughly 300,000 login details have already been compromised.

Conclusion

Overall, OmniStealer is a dangerous infostealer capable of extracting a wide range of sensitive data, including login credentials and cryptocurrency-related information. Its ability to target browsers, password managers, and cloud services makes it effective at hijacking accounts and engaging in financial theft. If a device is infected, the stealer should be removed immediately.

More examples of stealers are Storm, Remus, and Marco.

How did OmniStealer infiltrate my computer?

Devices typically become infected through social engineering. They often start with a fake job offer on platforms like LinkedIn or Upwork. Users are instructed to download and run a supposedly legitimate project from GitHub (or a file hosted on Google Docs, OneDrive, PuPI, or a similar platform).

In reality, a downloaded file is designed to connect to a blockchain network like TRON or Binance Smart Chain to receive malicious instructions. It then downloads and decrypts the final OmniStealer payload. Once executed, the malware begins stealing sensitive information.

How to avoid installation of malware?

Keep your operating system and installed applications up to date. Download programs only from official websites or trusted app stores, and avoid using cracked software, pirated tools, or key generators. Be cautious with unexpected emails, especially from unknown senders, and do not click on links or open attachments they contain.

When browsing unreliable websites, ignore suspicious pop-ups, ads, or prompts, and never allow such pages to send notifications. 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.

Extract the downloaded archive and run the Autoruns.exe file.

In the Autoruns application, click "Options" at the top and uncheck "Hide Empty Locations" and "Hide Windows Entries" options. After this procedure, click the "Refresh" icon.

Check the list provided by the Autoruns application and locate the malware file that you want to eliminate.

You should write down its full path and name. Note that some malware hides process names under legitimate Windows process names. At this stage, it is very important to avoid removing system files. After you locate the suspicious program you wish to remove, right click your mouse over its name and choose "Delete".

After removing the malware through the Autoruns application (this ensures that the malware will not run automatically on the next system startup), you should search for the malware name on your computer. Be sure to enable hidden files and folders before proceeding. If you find the filename of the malware, be sure to remove it.

Reboot your computer in normal mode. Following these steps should remove any malware from your computer. Note that manual threat removal requires advanced computer skills. If you do not have these skills, leave malware removal to antivirus and anti-malware programs.

These steps might not work with advanced malware infections. As always it is best to prevent infection than try to remove malware later. To keep your computer safe, install the latest operating system updates and use antivirus software. To be sure your computer is free of malware infections, we recommend scanning it with Combo Cleaner Antivirus for Windows.
