How Efimer Trojan Virus Installs on Systems

Efimer often arrives disguised behind seemingly urgent legal notices. Victims may receive a phishing email claiming domain infringements—usually with a password‑protected ZIP attachment (e.g. “Requirement.wsf”) posing as legal documentation.

Alternatively, downloading a “movie” from a compromised WordPress site may bundle a fake media player (XMPEG format) that actually installs the Trojan when opened.

Upon execution:

• If run with administrator privileges, Efimer excludes itself from Windows Defender and sets up persistence via scheduled tasks.
• If run without privileges, it adds itself to the Windows registry for auto‐start.
• In both cases, the Trojan installs a Tor proxy for encrypted communications with its command‑and‑control (C2) server.

What Data Efimer Trojan Tries to Steal

Efimer monitors your clipboard for any copied cryptocurrency wallet addresses—Bitcoin, Ethereum, Monero, Tron, Solana, and others—and swaps them for attacker‑controlled addresses that mimic the original.

It also looks for clipboard mnemonics (seed phrases) and:

• Saves them to a SEED file,
• Takes screenshots of your screen to capture sensitive content,
• Exfiltrates all this data via Tor to the attacker’s server.

Efimer can also act as a loader for further malicious actions, including brute‑forcing WordPress sites, harvesting email addresses, and distributing itself or spam to expand its reach.

Persistence Tactics Used by Efimer Trojan

Efimer embeds deep.

• Scheduled tasks (if run as admin) or Registry Run key (if run as a regular user) ensure it persists across startups.
• It installs the Tor client (e.g., ntdlg.exe) to obscure its communications and bypass detection.
• Its modular nature allows attackers to send remote commands (via Tor/C2), such as executing new scripts, exfiltrating data, or even self-deleting with a “KILL” command.

Manual Removal for Efimer Trojan Virus (For advanced users)

Step 1: Enter Safe Mode with Networking

Since info-stealers may resist removal while active, booting into Safe Mode helps disable their execution.

1. Windows 10/11:
   • Press Win + R, type msconfig, and hit Enter.
   • Go to the Boot tab and check Safe boot → Network.
   • Click Apply → OK and restart your PC.
2. Windows 7/8:
   • Restart your PC and keep pressing F8 before Windows loads.
   • Select Safe Mode with Networking and press Enter.

Step 2: End Malicious Processes in Task Manager

1. Press Ctrl + Shift + Esc to open Task Manager.
2. Look for suspicious processes (e.g., randomized names, high CPU usage, or unknown apps).
3. Right-click on them and select End Task.

Common info-stealer process names include StealC.exe, RedLine.exe, Vidar.exe, or generic system-like names.

---

Step 3: Uninstall Suspicious Programs

1. Press Win + R, type appwiz.cpl, and hit Enter.
2. Look for unknown or recently installed suspicious software.
3. Right-click the suspect entry and select Uninstall.

Step 4: Delete Malicious Files and Registry Entries

Info-stealers leave behind hidden files and registry keys to ensure persistence.

1. Open File Explorer and navigate to:
   • C:\Users\YourUser\AppData\Local
   • C:\Users\YourUser\AppData\Roaming
   • C:\ProgramData
   • C:\Windows\Temp
   Delete any unfamiliar folders with random names.
2. Open Registry Editor:
   • Press Win + R, type regedit, and press Enter.
   • Navigate to:
     • HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
     • HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
     • HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
     • HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce
   • Look for randomized or suspicious registry keys (e.g., StealerLoader, Malware123).
   • Right-click and delete any malicious entries.

Step 5: Clear Browser Data and Reset DNS

Since info-stealers target browsers, you need to clear stored credentials.

Clear Browsing Data

1. Open Chrome, Edge, or Firefox.
2. Go to Settings → Privacy and Security → Clear Browsing Data.
3. Select Passwords, Cookies, and Cached files and click Clear Data.

Reset DNS

1. Open Command Prompt as Administrator.
2. Type the following commands, pressing Enter after each:bashCopyEditipconfig /flushdns ipconfig /release ipconfig /renew
3. Restart your computer.

Step 6: Scan for Rootkits

Even after manual removal, some info-stealers may hide as rootkits.

1. Download Malwarebytes Anti-Rootkit or Microsoft Safety Scanner.
2. Run a deep scan and remove any detected threats.

---

Step 7: Change All Passwords & Enable MFA

Since info-stealers extract credentials, immediately update passwords for:

• Email accounts
• Banking and finance sites
• Social media
• Cryptocurrency wallets
• Business and work logins

Enable two-factor authentication (2FA) to prevent unauthorized access.
