How to get rid of REVSTEALER malware

What kind of malware is REVSTEALER?

REVSTEALER is an information stealer designed to harvest credentials, session tokens, and sensitive data from infected Windows computers. According to research published by Elastic Security Labs, the malware is tracked internally as REF2859 and has been active for at least a year, with roughly 4,700 samples matched in a VirusTotal retrohunt.

REVSTEALER is built with gamers specifically in mind. It steals session data from platforms like Steam and Roblox alongside browser passwords and cryptocurrency wallets. Beyond credential theft, it can receive additional modules from its operator that add cryptocurrency mining, clipboard hijacking, and proxy tunneling to an already compromised machine.

REVSTEALER overview

Once installed, REVSTEALER quietly collects credentials from over 225 supported Chromium browser extensions - covering cryptocurrency wallet extensions and password managers - and from 51 standalone wallet applications. It also pulls saved passwords, browser cookies, and authentication data from popular web browsers.

The stealer captures system screenshots, clipboard content, environment variables, process listings, and installed-application data. Windows Sticky Notes, OBS Studio files, 2FA application data, and data from VPN clients and messaging apps are targeted as well.

All collected data is sent to the attacker's command-and-control (C2) server. REVSTEALER bypasses Chrome's App-Bound Encryption protection using a debugger-based technique, allowing it to extract credentials that newer browser versions were designed to protect.

Targeted gaming platforms

A notable aspect of REVSTEALER is its deliberate focus on gaming. It targets session cookies and configuration files for Steam, Roblox, Minecraft, Battle.net, EA Desktop, and Battlestate Games. Because gaming session cookies allow account access without a password, cybercriminals can resell hijacked accounts on underground markets.

The stealer supports a wide range of browser extensions, including cryptocurrency wallet extensions and password managers, along with standalone software wallets installed on the system. This mix of gaming account theft and wallet harvesting makes REVSTEALER particularly damaging for players who also hold cryptocurrency.

Follow-on modules

REVSTEALER can receive additional modules from its C2 server after the initial infection, significantly expanding what it can do. Four main modules have been documented by Elastic Security Labs.

ProManager focuses on cryptocurrency wallet theft, browser extension data, and phishing overlays that silently capture passwords as the user types them. WinUpdate monitors the clipboard and swaps copied cryptocurrency wallet addresses with ones controlled by the attacker.

SoftManager turns the infected machine into a reverse SOCKS5 proxy, routing attacker traffic through the victim's internet connection. LockAppHost deploys an XMRig miner and sets up persistence so the malware survives reboots.

Evasion and anti-analysis features

Most REVSTEALER samples are packed with VMProtect, making analysis and detection significantly harder. The malware also runs a weighted sandbox scoring system with ten environmental checks. If the combined score reaches seven or higher - based on factors such as CPU core count, RAM, GPU vendor, and system uptime - the malware terminates itself.

REVSTEALER skips systems in CIS-region countries by checking keyboard layout and language settings. It also uses indirect system calls to bypass user-mode hooks that security software relies on, and encrypts its internal strings to avoid plaintext detection.

C2 infrastructure and blockchain resilience

REVSTEALER uses a two-tier C2 strategy. When the primary server is reachable, it communicates there directly. If the primary server goes offline - for example, after a hosting-provider takedown - the malware queries up to five Polygon blockchain endpoints to retrieve a fallback C2 address.

Storing C2 data inside a public blockchain smart contract makes it far harder for defenders to disrupt the operation. The operator can update the contract with a new server address at any time, restoring contact with already-infected machines. This approach provides unusual resilience compared to most commodity stealers.

Conclusion

REVSTEALER is a capable and stealthy threat that combines credential theft, gaming account hijacking, and cryptocurrency wallet harvesting with an extensible module system. Victims can lose access to gaming accounts, have cryptocurrency transactions silently redirected, and find their computers mining for an attacker in the background.

Its blockchain-based fallback C2, VMProtect packing, and sophisticated sandbox-evasion system make it harder to detect and disrupt than many common stealers. Any infected system should be cleaned immediately with a reputable security tool.

More examples of stealers are LLHN, Vanta, and WARDEN.

How did REVSTEALER infiltrate my computer?

According to Elastic Security Labs, REVSTEALER is primarily spread through hijacked YouTube channels. Cybercriminals take over established accounts with real subscriber bases and post AI-generated videos promoting free game cheats, mod menus, and trainers. At least 17 channels have been used this way, directing viewers to malicious domains such as elitecheatsx[.]live and resight-cheats[.]net.

Files downloaded from those sites impersonate legitimate programs including Slack, qBittorrent, Steel Series GG, and Blender. The installers carry the REVSTEALER payload. Victims believe they are installing a game enhancement tool when they are in fact running malware.

More broadly, trojans and stealers also reach users via phishing emails, malicious advertisements, untrustworthy download sites, P2P networks, and pirated software or cracks.

How to avoid installation of malware?

Be cautious with any software promoted through YouTube videos, social media, or gaming forums - especially "free" cheats, mods, or cracked tools. Download software only from the official developer's website or a trusted platform. Avoid pirated content, key generators, and game trainers from unknown sources.

Keep your operating system and all installed programs up to date, and use a reputable security suite with real-time protection. 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.

How to remove malware manually?

Most trojan infections can be removed by running a full system scan with Combo Cleaner. The full manual procedure below is for cases where automatic removal failed, where you want to verify a scan caught everything, or where the threat has multiple persistence points.

Tools you'll need

Combo Cleaner Antivirus 7-days free trial

Recommended primary scanner. VB100 certified. The 7-day free trial is available.

Microsoft Defender Offline Free · built-in

Built into Windows. Boots to a clean environment to catch rootkits.

Process Explorer Free

From Microsoft Sysinternals. Better than Task Manager - shows full paths and signatures.

Autoruns Free

From Microsoft Sysinternals. Lists every place malware can persist on your system.

Microsoft Safety Scanner (MSERT) Free

Official Microsoft on-demand scanner. Always-current signatures - expires every 10 days.

Phase 1~ 5 min

Contain - limit the damage

---

1

Disconnect from the network

30 secNo tool needed

Unplug your Ethernet cable and turn off Wi-Fi. If you're on a laptop, the airplane-mode key works fastest.

Why this matters

Many trojans exfiltrate data - saved browser passwords, banking sessions, screenshots - and accept remote commands. Cutting the network stops both immediately. Keep it disconnected until Phase 4.

2

Boot into Safe Mode with Networking

3 min

Safe Mode loads a minimal set of drivers and stops most malware from auto-running. "With Networking" lets you download tools - re-enable Wi-Fi only after you've booted in.

Windows 11

Open Settings → System → Recovery. Click Restart now next to Advanced startup.

Your computer will restart into the "Choose an option" menu. Click Troubleshoot → Advanced options → Startup Settings → Restart. After the second reboot, press 5 or F5.

Windows 10

Click the Windows logo, hold Shift, click the Power icon and choose Restart. In the Choose an option screen, click Troubleshoot → Advanced options → Startup Settings → Restart. Press F5.

Windows 8

Go to the Start Screen, type Advanced, select Settings → Advanced startup options → Restart now → Troubleshoot → Advanced options → Startup settings → Restart → F5.

Note: Windows 8 reached end-of-life in January 2023 - running on it puts you at much higher risk of reinfection.

Windows 7

Click Start → Shut Down → Restart → OK. As the system boots, press F8 repeatedly until the Windows Advanced Options menu appears, then choose Safe Mode with Networking.

Note: Windows 7 reached end-of-life in January 2020 - running on it puts you at much higher risk of reinfection.

Phase 2~ 15 min

Identify - find what's hiding

---

3

Inspect running processes with Process Explorer

Tool: Process Explorer5 min

Download Process Explorer from Microsoft Sysinternals. Run it as Administrator. Click Options → Verify Image Signatures and View → Lower Pane View → DLLs.

Sort by "Verified Signer." Anything unsigned running from %AppData%, %LocalAppData%, %Temp%, or %ProgramData% is suspicious. Right-click → Properties to see the full image path. Right-click → "Search Online" to look up unfamiliar process names.

Why not just Task Manager

Task Manager hides full file paths, doesn't show digital signatures, and groups processes in ways that make malware easy to miss. Process Explorer is the same tool Microsoft engineers use.

4

Map every persistence point with Autoruns

Tool: Autoruns 14.x10 min

Download Autoruns. Right-click Autoruns.exe and choose Run as administrator - without elevation, Autoruns can't inspect protected registry hives.

In the menu, open Options → Hide Microsoft Entries and Options → Hide Empty Locations, then click Refresh.

Modern trojans don't just live in startup. Walk through these tabs and look for unsigned or unfamiliar entries:

• Logon - classic Run/RunOnce keys
• Scheduled Tasks - frequent hiding spot, especially tasks with PowerShell, MSHTA, or rundll32 actions
• Services - unsigned services in non-Microsoft folders
• WMI - Event Subscriptions are a stealthy persistence mechanism (MITRE T1546.003)
• Image Hijacks - Image File Execution Options "Debugger" abuse
• AppInit - DLLs loaded into every GUI process
• Browser plug-ins - unsigned add-ons across all installed browsers

Pro tip

Right-click any suspicious entry → "Jump to Image" to see the actual file. Right-click → "Search Online" opens VirusTotal for the file hash. Don't delete yet - just write down the file paths and entry names. We'll remove them after the scans.

5

Check the hosts file and DNS settings

3 minBuilt into Windows

Trojans often redirect bank, antivirus, and update domains to attacker-controlled servers by editing the hosts file or DNS settings.

Hosts file: Open Notepad as Administrator and open C:\Windows\System32\drivers\etc\hosts. Legitimate entries are commented with #. Any uncommented IP-to-domain mapping is suspicious - especially redirects for microsoft.com, windowsupdate, or your bank.

DNS settings: Open Command Prompt as Administrator and run ipconfig /all. Confirm your DNS servers point to your ISP, your router, or a known public resolver (Cloudflare 1.1.1.1, Google 8.8.8.8). Then open Settings → Network & internet → [your adapter] → DNS server assignment and verify both DNS and DNS over HTTPS (DoH) settings haven't been hijacked.

Why this matters

A clean PC with hijacked DNS is still a compromised PC. You'll think you're at chase.com and you'll be at the attacker's clone.

Phase 3~ 60-90 min

Remove - three scans, one cleanup

---

No single antivirus catches everything. The order below is intentional: offline scan first (catches rootkits before Windows fully loads), then on-demand scanners on the running system, then manual cleanup of anything they missed.

6

Run Microsoft Defender Offline

Tool: Built into Windows15 min

Reboot to normal Windows. Open Windows Security → Virus & threat protection → Scan options. Select Microsoft Defender Antivirus (offline scan) and click Scan now. Your computer will restart into a stripped-down environment and scan before the full operating system loads.

Why this comes first

Rootkits and bootkits hide from any scanner running on the same Windows session that's already infected. A pre-boot offline scan sees the disk before the malware can hide itself.

Recommended antivirus

Combo Cleaner

VB100 certified. Includes anti-trojan, registry/persistence scanning, anti-spyware in one pass. The 7-day free trial is available.

Download Combo Cleaner

7

Run Combo Cleaner full system scan

Tool: Combo Cleaner20-40 min

Install Combo Cleaner and run a full system scan (not the quick scan). Let it complete fully, review the detected threats, and apply the recommended actions. Combo Cleaner will quarantine known trojans and registry persistence.

8

Run Microsoft Safety Scanner as a second-opinion scan

Tool: Microsoft Safety Scanner15 min

Download Microsoft Safety Scanner (MSERT.exe), Microsoft's free on-demand tool. The binary expires every 10 days, which means every download has the latest signatures. Run a full scan after Combo Cleaner to catch anything one engine alone might miss.

Why a second scan

Different scanning engines catch different threats. Running an additional Microsoft scan after Combo Cleaner is the single most underused verification step in malware removal.

9

Manually remove anything still listed in Autoruns

Tool: Autoruns10 min

Reopen Autoruns. Anything you flagged in Step 4 that's still present hasn't been caught by the automated scans. For each remaining suspicious entry: right-click → Delete in Autoruns (this removes the persistence registration), then navigate to the file path and delete the actual file. Empty the Recycle Bin.

Important

Some malware files reappear after deletion because something else on the system recreates them. If you delete a file and it returns within minutes, you have a remaining persistence point that Autoruns didn't show - usually a service or scheduled task running under SYSTEM. Re-run the scans from Steps 6-8 or proceed to a clean install (see end of guide).

Phase 4~ 15 min

Recover - restore browsers and security

---

10

Reset browsers and clear notification permissions

5 min

Trojans and adware frequently hijack browsers - change the default search engine, install rogue extensions, or grant themselves notification permissions to keep displaying scam pop-ups even after the malware is gone.

• Chrome: visit chrome://settings/reset and click "Restore settings to their original defaults." Then visit chrome://settings/content/notifications and remove any unfamiliar sites.
• Edge: visit edge://settings/reset. Then check edge://settings/content/notifications.
• Firefox: open about:support and click Refresh Firefox (Firefox uses "Refresh," not "Reset"). Then check Settings → Privacy & Security → Permissions → Notifications.

Review installed extensions in each browser and remove anything you don't recognize, especially extensions you didn't install yourself.

11

Re-enable Defender, Tamper Protection, and update everything

10 min

Many trojans disable security software. Open Windows Security → Virus & threat protection → Manage settings and confirm Real-time protection, Cloud-delivered protection, and Tamper Protection are all turned on. Tamper Protection prevents malware from disabling Defender silently.

Then run Windows Update (Settings → Windows Update → Check for updates) and update your browsers and applications. The infection vector that let the trojan in originally usually involves outdated software.

Phase 5~ 15 min + 7 days

Verify & secure

---

12

Change passwords from a clean device

20 min⚠ Critical

If the trojan was an info-stealer (Lumma, RedLine, Vidar, and similar are extremely common), assume every password saved in your browser is compromised. Change them from a different, known-clean device - your phone is fine if it's not infected.

Recommended order:

1. Primary email first - it's the recovery hub for everything else
2. Banking and financial accounts
3. Password manager master password (if you use one)
4. Social media, shopping, and remaining accounts

Where available, enable phishing-resistant multi-factor authentication (passkeys / FIDO2 hardware keys / authenticator apps) - SMS-based MFA is bypassable by sophisticated attackers.

13

Verify the clean and monitor for 7 days

5 min + 1 week monitoring

Reconnect to the network and run one final full scan with Combo Cleaner. Open Task Manager (Ctrl + Shift + Esc) and switch to the Startup apps tab - confirm nothing suspicious has reappeared.

Over the next 7 days, watch for symptom recurrence: unexpected high CPU usage, unknown processes returning, browser redirects, or pop-ups. If anything returns, you missed a persistence point and the procedure needs to be repeated - or you may have a deeper compromise that requires a clean install.

When to clean install Windows instead

Manual removal isn't always the right answer. Reinstalling Windows from scratch is the only way to be 100% certain when:

• The malware reappears after every removal attempt
• A bootkit or UEFI rootkit was detected (this class of threat sits below the operating system and survives a normal Windows reinstall)
• A confirmed credential-theft trojan ran with administrator privileges (Lumma, RedLine, Vidar) - the system likely has multiple unknown payloads
• The PC is used for online banking, business email, or anything where partial doubt isn't acceptable

A clean install is a 30-60 minute process: Windows 11 reinstall via Settings → System → Recovery → Reset this PC → Remove everything → Cloud download. Back up documents to external storage first, scan the backup with Combo Cleaner before restoring it, and reinstall applications fresh - never restore them from a backup of the infected system.

Important: Manual removal requires advanced computer skills. If you're not confident identifying system files from malicious files, run an automated scan with Combo Cleaner and Windows Defender and stop there - that path catches the vast majority of consumer trojans without the risk of breaking Windows by deleting the wrong file.

Frequently Asked Questions (FAQ)

My computer is infected with REVSTEALER malware, should I format my storage device to get rid of it?

Formatting the drive will remove REVSTEALER but also erase every file on it. Running a reputable security tool such as Combo Cleaner is the better first step - it can detect and eliminate the malware without destroying your data.

What are the biggest issues that REVSTEALER malware can cause?

REVSTEALER can steal saved passwords, browser cookies, and cryptocurrency wallet files, leading to account takeover and financial loss. It also targets gaming accounts on platforms like Steam and Roblox, which cybercriminals resell on underground markets.

Through its follow-on modules, the malware may silently redirect cryptocurrency transactions, mine digital currency using the victim's hardware, and route attacker traffic through the victim's internet connection.

What is the purpose of REVSTEALER malware?

REVSTEALER is designed to steal credentials and session data with a particular focus on gaming accounts and cryptocurrency wallets. Its extensible module system also allows operators to add clipboard hijacking, mining, and proxy capabilities after the initial infection.

How did REVSTEALER malware infiltrate my computer?

REVSTEALER has been distributed through hijacked YouTube channels advertising free game cheats or mod menus. Clicking the links in those videos leads to malicious sites where the payload is disguised as a legitimate program such as Slack or qBittorrent.

Will Combo Cleaner protect me from malware?

Yes. Combo Cleaner can detect and remove most known malware. Because REVSTEALER uses VMProtect packing and advanced evasion techniques, running a full system scan is recommended to make sure nothing is missed.
