RevStealer is a Windows-based information-stealing malware that has been targeting home users and small businesses since its first appearance in malware distribution campaigns. This trojan is designed to harvest sensitive data from infected machines — browser credentials, cryptocurrency wallet files, FTP client passwords, and other stored authentication information — then silently transmit everything to remote attackers. Unlike ransomware that announces itself immediately, RevStealer operates quietly in the background, which means many victims don't realize they've been compromised until fraudulent charges appear or accounts get taken over.
We see this threat regularly at our Roswell shop, often on machines that were infected through fake software downloads or malicious email attachments. The good news is that RevStealer can be removed with the right approach, and we'll walk you through both what this malware does and how to eliminate it from your system.

How It Spreads
RevStealer typically arrives on systems through social engineering tactics that trick users into running the malicious executable. The most common infection vector we encounter is fake software downloads — someone searches for a free PDF converter, a video codec, or a cracked version of commercial software, and the download page looks legitimate but delivers RevStealer bundled with (or disguised as) the expected program. These distribution sites often rank well in search results and mimic trusted download portals.
Email phishing remains another major distribution channel. Attackers send messages with subject lines about package deliveries, invoice discrepancies, or urgent account notifications. The attached file might be labeled "Invoice_2024.exe" or hidden inside a ZIP archive. Once the victim opens it, RevStealer installs silently while displaying a fake error message to explain why "the document wouldn't open."
We've also seen RevStealer distributed through:
- Trojanized installers — legitimate-looking setup files for popular freeware that include the stealer as a hidden payload
- Malicious advertisements — compromised ad networks serving drive-by downloads or fake browser update prompts
- Software cracks and keygens — pirated software bundles that always carry additional malware risks
- Discord and Telegram links — shared files in gaming or tech communities, often presented as mods, cheats, or helpful utilities
- Compromised WordPress sites — legitimate-looking business websites that have been hacked to distribute malware through fake download buttons
What It Does On Your Machine
Once executed, RevStealer gets to work immediately harvesting stored credentials and sensitive files. The malware targets browser data first — saved passwords, autofill information, cookies, and browsing history from Chrome, Firefox, Edge, Opera, and Brave. It specifically hunts for authentication tokens that can be used to access your accounts without needing passwords. Many users don't realize how much sensitive information their browser stores until malware extracts all of it in seconds.
Beyond browsers, RevStealer scans your system for cryptocurrency wallet files (Electrum, Exodus, Atomic, Coinomi, and others), FTP client credentials (FileZilla, WinSCP), email client data (Thunderbird, Outlook profiles), and Discord tokens. It also looks for text files on the desktop and in Documents folders that might contain passwords or account information — people often save these in files named "passwords.txt" or similar, which makes the attacker's job trivial.
The malware establishes persistence so it survives reboots, typically by adding registry entries or creating scheduled tasks. It then packages all stolen data into an encrypted archive and transmits it over HTTPS to the attacker's command-and-control server. The encryption and use of legitimate protocols make this exfiltration difficult for basic firewalls to detect. Here's what typical RevStealer activity looks like on an infected system:
What makes RevStealer particularly concerning is that it operates without obvious symptoms. Your computer doesn't slow down noticeably, no ransom note appears, and Windows continues functioning normally. The only signs might be brief disk activity or a momentary network spike that most users would never notice. By the time you discover fraudulent charges or locked-out accounts, your credentials have already been sold on dark web marketplaces or used for further attacks.
Manual Removal — Step by Step
Disconnect From the Internet Immediately
Before doing anything else, disconnect your computer from all networks. Unplug the Ethernet cable or disable Wi-Fi. This prevents RevStealer from continuing to transmit stolen data and stops attackers from sending additional commands to the malware. Keep the system offline throughout the entire removal process.
Boot Into Safe Mode With Networking
Restart your computer and press F8 (or Shift+F8 on newer systems) during boot to access Advanced Boot Options. Select "Safe Mode with Networking." This loads Windows with minimal drivers and prevents most malware from auto-starting, while still allowing you to download tools. On Windows 10/11, you may need to use Settings > Update & Security > Recovery > Advanced Startup to access Safe Mode.
Run a Full System Scan With Updated Security Software
Use a reputable anti-malware tool (Malwarebytes, Emsisoft, or Kaspersky Rescue Disk) to perform a complete system scan. Make sure the software updates its definitions first, even if you have to briefly reconnect to download them. Let the scan complete fully — this typically takes 45–90 minutes. Quarantine or delete all detected threats. Run a second scan with a different tool to catch anything the first one missed.
Check and Remove Persistence Mechanisms
Press Windows+R, type msconfig, and check the Startup tab for suspicious entries with random names or paths pointing to AppData folders. Disable anything you don't recognize. Then press Windows+R again, type taskschd.msc to open Task Scheduler, and review the Task Scheduler Library for unusual scheduled tasks. Delete any that reference random executables or have suspicious triggers. Also check Registry Run keys: press Windows+R, type regedit, and navigate to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run — remove any entries you don't recognize.
Manually Delete RevStealer Files
Open File Explorer and navigate to C:\Users\[YourUsername]\AppData\Roaming and C:\Users\[YourUsername]\AppData\Local\Temp. Look for folders with random names created on or after your suspected infection date. RevStealer often creates folders with strings of random characters. Delete any suspicious folders and their contents. Empty the Recycle Bin afterward. Be careful not to delete legitimate program folders — when in doubt, search the folder name online first.
Clear Browser Data Completely
Since RevStealer steals browser credentials and cookies, you need to purge all saved data. In each browser you use, go to Settings and clear browsing data — select "All time" as the time range and check every box (cookies, passwords, cache, autofill, everything). This will log you out of all websites, which is necessary since your session tokens are compromised. You'll need to log back in with fresh credentials after changing your passwords.
Change All Passwords From a Clean Device
Using a different computer, tablet, or smartphone that you're certain is clean, change passwords for every account: email, banking, social media, shopping sites, work accounts — everything. Enable two-factor authentication (2FA) on every service that offers it. Start with your email accounts first, since those can be used to reset other passwords. Use unique passwords for each account, preferably managed by a password manager. Do NOT change passwords from the infected machine, even after running antivirus scans.
Monitor Financial Accounts
Check your bank accounts, credit cards, and any cryptocurrency wallets for unauthorized transactions. Contact your financial institutions immediately if you see anything suspicious — they can freeze accounts and issue new cards. Place a fraud alert or credit freeze with the major credit bureaus (Equifax, Experian, TransUnion) to prevent identity theft. Monitor accounts closely for the next several months, as stolen credentials sometimes aren't used immediately.
Verify Complete Removal
After completing the above steps, restart your computer normally (not Safe Mode) and run one final full system scan with your security software. Check Task Manager (Ctrl+Shift+Esc) for suspicious processes and Resource Monitor for unusual network activity. If the scans come back clean and you don't see signs of malware, the removal was likely successful. However, remain vigilant — if you notice any unusual account activity or system behavior in the coming weeks, the infection may not have been completely eliminated.
Consider Professional Verification
Information stealers are particularly tricky because they can drop additional malware or establish backdoors. If you handled any sensitive business data, financial transactions, or work-related accounts on the infected machine, we strongly recommend bringing the computer in for professional verification. We can perform forensic checks that go beyond standard antivirus scans to ensure no remnants or secondary payloads remain. This is especially important for business computers where a missed infection component could lead to further data breaches.
Prevention
- Download software only from official sources. Always get programs directly from the developer's website or the Microsoft Store. Avoid third-party download sites, even ones that look professional. If you need freeware, verify the official source before downloading. Never download cracked or pirated software — the malware risk far outweighs any cost savings.
- Scrutinize email attachments and links. Don't open attachments from unexpected emails, even if they appear to come from known senders (email addresses can be spoofed). Hover over links to check the actual URL before clicking. Be especially suspicious of ZIP files, executables, or documents that ask you to "enable macros." When in doubt, contact the supposed sender through a different communication channel to verify they actually sent the file.
- Keep security software running and updated. Install reputable antivirus software and keep it active with real-time protection enabled. Windows Defender is adequate for most users if kept updated, but commercial solutions offer additional protection layers. Ensure your security software updates automatically and runs regular scheduled scans. Don't disable protection "temporarily" — that's exactly when you're most vulnerable.
- Use a password manager with unique passwords. Stop reusing passwords across sites. A password manager like Bitwarden, 1Password, or Keeper generates strong unique passwords for every account and stores them securely. This means that even if one site gets compromised, attackers can't use that password to access your other accounts. Enable two-factor authentication everywhere it's offered as an additional security layer.
- Keep Windows and all software updated. Enable automatic updates for Windows, browsers, and common programs like Adobe Reader and Java. Many malware infections exploit known vulnerabilities in outdated software. Updates often include security patches that close these holes. Set aside time monthly to update programs that don't update automatically.
- Be skeptical of urgent requests and too-good-to-be-true offers. Attackers use psychological pressure to bypass your critical thinking. Emails claiming your account will be closed unless you act immediately, offers for expensive software completely free, alerts that you've won contests you never entered — these are social engineering tactics. Slow down and evaluate suspicious communications rationally before acting.
- Limit what you store in browsers. While browser password managers are convenient, they're prime targets for stealers. Consider using a standalone password manager instead. Minimize saved payment information and regularly clear stored data. Be especially cautious about saving banking credentials in browsers. The less sensitive data stored locally, the less attackers can harvest if you do get infected.
- Maintain offline backups of critical data. Information stealers target your stored data, and other malware can encrypt or delete it. Keep regular backups of important files on an external drive that you disconnect when not backing up. This also protects you from ransomware, hardware failures, and accidental deletion. Follow the 3-2-1 rule: three copies of data, on two different media types, with one copy offsite.
