BoryptGrab Stealer is an information-stealing trojan designed to extract sensitive data from infected Windows systems. This malware specifically targets cryptocurrency wallet credentials, browser-stored passwords, authentication cookies, and other financial information. Once installed, BoryptGrab operates silently in the background, harvesting data and transmitting it to remote command-and-control servers operated by cybercriminals.
Unlike ransomware that announces its presence, information stealers like BoryptGrab work to remain undetected for as long as possible. The longer it stays active on your system, the more data it can exfiltrate. Victims often don't realize they're compromised until they notice unauthorized transactions, account takeovers, or identity theft incidents.

How It Spreads
BoryptGrab Stealer reaches victims through several well-established infection vectors, often exploiting human trust rather than technical vulnerabilities. The malware authors constantly adapt their distribution methods to evade detection and maximize infection rates.
Email campaigns represent the primary distribution channel. Attackers send messages impersonating shipping companies, financial institutions, or business partners, with attachments that appear to be invoices, receipts, or important documents. These attachments may be disguised as PDFs but are actually executables with double extensions (like "Invoice_2024.pdf.exe") or archive files containing the malware payload.
Software piracy sites and torrent repositories serve as another major infection source. Users searching for cracked versions of expensive software, key generators, or license activation tools frequently download trojanized installers that bundle BoryptGrab with the promised application. The malware installs silently alongside the legitimate-looking program.
Common distribution methods include:
- Malicious email attachments — ZIP, RAR, or 7z archives containing executable files disguised as documents
- Fake software cracks and keygens — Trojanized piracy tools advertised on warez forums and torrent sites
- Compromised websites — Drive-by downloads triggered when visiting infected or malicious sites
- Malvertising campaigns — Poisoned advertisements on legitimate websites that redirect to exploit kits
- Fake update notifications — Bogus browser, Flash, or codec update prompts
- Social media links — Shortened URLs in posts/messages leading to malware download pages
- Supply chain attacks — Legitimate software repositories temporarily compromised to distribute trojanized versions
- Remote desktop brute-forcing — Exploitation of weak RDP credentials to manually install the stealer
What It Does On Your Machine
Upon execution, BoryptGrab Stealer immediately begins establishing persistence and surveying your system for valuable data. The malware typically extracts itself to a randomly-named folder in your user profile directory and creates multiple persistence mechanisms to ensure it survives system reboots.
The stealer's primary function is harvesting credentials and sensitive information from various sources. It targets browser profile folders where Chrome, Firefox, Edge, and other browsers store login credentials, saved payment methods, and authentication cookies. These files are typically SQLite databases that the malware copies and exfiltrates. BoryptGrab also specifically searches for cryptocurrency wallet files and configuration data from popular wallet applications. If you've stored wallet credentials or seed phrases in text files or password managers, the malware will attempt to access those as well.
BoryptGrab monitors your clipboard for cryptocurrency addresses, replacing them with attacker-controlled addresses when you attempt to make a transaction. This clipboard-hijacking functionality means that even if you copy-paste a legitimate wallet address, the malware silently substitutes a different address at the moment of transaction, redirecting your funds to the attackers.
The collected data is compressed, encrypted, and transmitted to remote command-and-control servers. This network communication typically occurs over HTTPS to blend with normal web traffic and evade basic network monitoring. The malware may also download additional payloads — secondary stealers, ransomware, or remote access trojans — turning your compromised system into a platform for further attacks.
Manual Removal — Step by Step
Disconnect from Network Immediately
Before attempting any removal steps, disconnect your computer from all networks. Unplug the Ethernet cable and disable Wi-Fi from the system tray. This prevents the malware from transmitting any additional data or downloading further payloads. If you're on a business network, notify your IT department immediately.
Boot Into Safe Mode with Networking
Restart your computer and boot into Safe Mode to prevent BoryptGrab from loading automatically. On Windows 10/11, hold Shift while clicking Restart, then navigate to Troubleshoot > Advanced Options > Startup Settings > Restart, and press F5 for Safe Mode with Networking. This allows the operating system to load without starting most third-party software, including the stealer.
Identify and Terminate Malicious Processes
Open Task Manager (Ctrl+Shift+Esc) and look for suspicious processes with random names, high memory usage, or processes running from unusual locations like %TEMP% or %LOCALAPPDATA% with GUID-style folder names. Right-click any suspicious process, select "Open file location" to verify its path, then end the process. BoryptGrab often disguises itself with names mimicking legitimate Windows processes but running from wrong locations.
Remove Persistence Mechanisms
Press Win+R, type "regedit" and press Enter to open Registry Editor. Navigate to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run and HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run. Look for entries with suspicious names or paths pointing to random folders. Delete any unfamiliar entries. Also check Task Scheduler (type "taskschd.msc" in Win+R) for scheduled tasks with generic names like "SystemMaintenance" or "UpdateService" that run executables from temporary folders.
Delete Malware Files and Folders
Using File Explorer with hidden files visible (View > Hidden Items), navigate to %LOCALAPPDATA%, %APPDATA%, and %TEMP% directories. Delete any folders with random GUID-style names or suspiciously generic names that weren't present before infection. Be cautious not to delete legitimate system folders. Look for folders created around the time you noticed unusual behavior or that match the paths identified in Task Manager.
Scan with Reputable Anti-Malware Tools
Download and run Malwarebytes Premium or another reputable anti-malware tool. While still in Safe Mode with Networking enabled, perform a full system scan. These tools have updated definitions for BoryptGrab variants and can identify remnants you may have missed. Allow the software to quarantine or remove all detected threats. Consider running a second scan with a different tool (like HitmanPro or ESET Online Scanner) for verification.
Reset All Browsers
Since BoryptGrab steals browser credentials and may install malicious extensions, reset all installed browsers to default settings. In Chrome/Edge, go to Settings > Reset and clean up > Restore settings to their original defaults. In Firefox, use Help > More Troubleshooting Information > Refresh Firefox. This removes extensions, clears cookies, and resets settings while preserving bookmarks.
Change All Passwords From a Clean Device
Using a different, uninfected device (smartphone, tablet, or another computer), immediately change passwords for all critical accounts: email, banking, cryptocurrency exchanges, social media, and any other accounts containing sensitive information. Enable two-factor authentication wherever possible. Assume that all credentials stored on the infected machine have been compromised.
Monitor Financial Accounts and Cryptocurrency Wallets
Check all cryptocurrency wallets for unauthorized transactions. If you stored wallet credentials or seed phrases on the infected system, transfer remaining funds to new wallets with fresh seed phrases generated on a clean device. Review bank and credit card statements for suspicious activity. Consider placing fraud alerts with credit bureaus if you believe personal identification information was stored on the compromised machine.
Reboot and Verify System Integrity
Restart your computer normally (not in Safe Mode) and verify that no suspicious processes return. Monitor system behavior for several days. If you notice continued unusual activity—unexpected network traffic, processes reappearing, or system performance degradation—the malware may not be fully removed. In this case, professional assistance is strongly recommended to ensure complete eradication.
Prevention
- Never download cracked software or keygens. Piracy sites are the most common distribution channel for information stealers. Legitimate software subscriptions cost far less than recovering from identity theft or cryptocurrency loss.
- Scrutinize email attachments before opening. Verify sender identity through secondary channels. Be especially wary of unexpected attachments with double extensions (.pdf.exe, .doc.scr) or executable files inside ZIP archives. When in doubt, contact the supposed sender using contact information you look up independently.
- Keep antivirus software active and updated. Modern antivirus solutions with real-time protection and behavioral detection can block most stealer variants before they execute. Don't disable your security software, even temporarily, for installations.
- Store cryptocurrency credentials offline. Use hardware wallets for cryptocurrency storage rather than software wallets on internet-connected computers. Never store seed phrases, private keys, or wallet passwords in text files, browser password managers, or cloud storage.
- Use strong, unique passwords with a dedicated password manager. A reputable password manager encrypts credentials with a master password unknown to the malware. This limits damage if your system is compromised—the attacker gets encrypted vaults rather than plaintext credentials.
- Enable two-factor authentication on all critical accounts. Even if a stealer captures your password, 2FA provides a second barrier against unauthorized access. Use authenticator apps or hardware tokens rather than SMS-based verification when possible.
- Update operating system and applications regularly. Keep Windows, browsers, and all software current with security patches. Enable automatic updates to close vulnerabilities that malware exploits for initial access or privilege escalation.
- Practice cautious browsing habits. Avoid clicking on shortened URLs from unknown sources, advertisements promising free premium content, or pop-ups claiming your system is infected. Use ad-blocking extensions to reduce exposure to malvertising campaigns.
