What is YTStealer?

YTStealer is a piece of malicious software classified as a stealer. Malware within this category aims to steal a wide variety of sensitive data. However, YTStealer targets very specific information - one relating to victims' YouTube accounts. Thus the goal of the attackers behind this program is to gain access and control over YouTube accounts.

YTStealer malware overview

Following successful infiltration, YTStealer first checks whether it is running in a virtual environment. The module this program uses is based on an open-source project, which uses anti-VM, anti-debugging, and anti-memory functionalities.

YTStealer is designed to extract YouTube authentication cookies and other information relating to the accounts on this platform (e.g., channel name and age, subscriber count, monetization status, etc.). The cookies are obtained from the browser's database files (user profile folder).

This stealer also employs another module that allows high-level control over browsers. It then stealthily uses the browser to check the validity of the obtained data.

The research done by Intezer suggests that the cyber criminals behind YTStealer use this malware to acquire and subsequently sell stolen accounts belonging to YouTube content creators.

Since YTStealer is designed to extract particular data, it is no surprise that this program has been observed being proliferated alongside other information-stealing malware like Vidar and RedLine.

In summary, malware like YTStealer can cause severe privacy issues, financial losses, and identity theft. If you suspect that your system is infected with YTStealer (or other malicious software), we strongly advise using an anti-virus to eliminate it without delay.

Stealer-type malware examples

We have analyzed countless stealers; RedoxBlueShtorm, and Growtopia are merely a couple of examples. Malware designed to extract data can target a broad range of different information.

Furthermore, malicious programs often have varied abilities and/or download/install additional malware (e.g., trojans, ransomware, etc.). Therefore, regardless of how a malicious program operates - its presence on a system endangers device integrity and user safety.

How did YTStealer infiltrate my computer?

Malware is usually proliferated using phishing and social engineering tactics. It is commonly disguised as and/or bundled with regular programs/media. Virulent files can be executables, archives, Microsoft Office and PDF documents, JavaScript, etc. Once an infectious file is opened - malware download/installation is jumpstarted.

The most common distribution methods include: untrustworthy download channels (e.g., freeware and third-party websites, P2P sharing networks, etc.), illegal program activation ("cracking") tools, online scams, malicious attachments and links in spam emails and messages, fake updaters, and malvertising.

Intezer researchers have found YTStealer being distributed under the guise of various image/video-related software products (OBS Studio, Adobe Premiere Pro, Filmora, HitFilm Express, etc.), audio-related programs and plug-ins (Ableton Live 11 Suite, Antares Auto-Tune Pro, FabFilter Total, FL Studio, Valhalla DSP, Xfer Serum, etc.), video-game mods and cheats/hacks (FiveM Grand Theft Auto V, Call of Duty, Counter-Strike Go, Roblox, Valorant, etc.), drivers (Driver Booster, Driver Easy, etc.), "cracked" software (Norton AntiVirus, Malwarebytes, Discord Nitro, Spotify Premium, Stepn, etc.).

How to avoid installation of malware?

We highly recommend downloading only from official and verified channels. Furthermore, software must be activated and updated using legitimate functions/tools, as illegal activation ("cracking") tools and fake updaters may contain malware.

We also advise exercising caution with incoming mail. The attachments and links found in suspect emails and messages - must not be opened since that may result in a system infection.

It is crucial to have a reputable anti-virus installed and kept up-to-date. Security programs must be used to run regular system scans and to remove detected threats and issues. 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.

After you locate the suspicious program you wish to remove, right click your mouse over its name and choose "Delete".

Delete malware in Autoruns

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.

Search for malware and delete 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.
