How to eliminate Olymp Loader from infected devices

What kind of malware is Olymp Loader?

Olymp Loader is a Malware‑as‑a‑Service sold on underground forums and Telegram. The developer claims it is written in assembly and advertises it as FUD (Fully Undetectable). The loader is priced at $50 (basic), $100 (tweaked), and $200 (with custom code and injection into legitimate programs).

More about Olymp Loader

One of the main capabilities of an Olymp Loader is injecting additional payloads. Most cybercriminals using Olymp Loader deploy credential stealers and remote access tools (RATs), such as LummaC2, QasarRAT, Raccoon, and WebRAT, on compromised devices. However, the loader has additional modules.

These modules include browser, Telegram, and crypto wallet data stealers. The browser data stealer targets passwords, cookies, bookmarks, autofill data, and credit card information from web browsers.

The Telegram stealer module can find where Telegram is installed on the computer, read a proxy address from a file, take screenshots of all monitors, close Telegram-related processes, and gather Telegram data files.

The crypto wallet stealer module is designed to steal cryptocurrency wallet data from wallets like Atomic, Bitcoin Core, Electrum, Exodus, Guarda, Monero, Wasabi, and ZelCore. This module also takes screenshots of every monitor. It was observed that the loader compresses stolen information before sending it to the attackers.

Overall, cybercriminals can steal cryptocurrency by copying wallet files and private keys, causing irreversible financial loss. They can also grab passwords, session tokens, and other data to take over email, social media, and banking accounts. Stolen data can be sold or used for identity theft and fraud, and attackers may use it to target the victim's contacts.

Injected additional malware can be used to steal more data, encrypt files, mine cryptocurrency, and more. If detected on a device, Olymp Loader (and additional payloads) should be eliminated as soon as possible.

It is important to note that Olymp Loader comes in multiple versions, with various builds and variants.

Conclusion

Olymp Loader is a versatile malware that allows attackers to deploy additional payloads, including credential stealers, remote-access tools, and modules targeting browsers, Telegram, and crypto wallets. It enables cybercriminals to steal sensitive information, take over accounts, and cause financial or identity-related damage.

Immediate removal is essential to prevent possible outcomes. BaoLoader, SoupDealer, and QuirkyLoader are other examples of malware classified as a loader.

How did Olymp Loader infiltrate my computer?

Olymp Loader is being distributed in several ways. Cybercriminals have hosted binaries as GitHub release assets disguised as "NodeJs.exe" to trick developers into infecting their devices with the loader. The loader also appears as a second stage delivered by Amadey, another malware that can inject additional payloads.

Threat actors have also been observed tricking users into downloading Olymp Loader by making infected files look like popular software. They use names like PuTTY, OpenSSL, Zoom, or Classic Offensive and sometimes copy the app's icon or use its certificate to make it seem legitimate. They have also mimicked apps like NodeJS, Capcut, SumatraPDF, and PeaZip.

How to avoid installation of malware?

Be careful with emails or messages you were not expecting, especially if they contain links or attachments from unknown senders. Download apps or files from official websites or well-known app stores. Never download pirated software, cracking tools, or keygens. Regularly update your operating system and applications.

Avoid clicking on suspicious ads or pop-ups, and do not let untrustworthy websites send you notifications. Also, use trusted security software to scan your device. 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.
