Is NepTunnel 2.2.exe safe?

Verdict
Suspicious

Five of 74 engines flagged this unsigned proxy utility, while runtime injection and LSASS-related indicators plus multiple YARA matches warrant substantial caution.

The executable has no verified publisher and drew five detections among 74 engines, including a ProxyAgent riskware label, though no tier-1 engine flagged it. Runtime evidence mapped to process injection and LSASS-related activity, and multiple research rules matched, so it should not be trusted without source verification.

Do not run it until verified

Quarantine the executable pending verification from an official publisher or release channel, and avoid entering credentials or granting elevated privileges. Keep antivirus and endpoint protection enabled.

01

Before running

Do not run it until the source and publisher can be verified independently.

02

If you already ran it

Stop using it, scan the device, and watch for unexpected behavior or security alerts. Get a fresh copy from the developer's official site or an official app store.

Analyst conclusion

The executable has no verified publisher and drew five detections among 74 engines, including a ProxyAgent riskware label, though no tier-1 engine flagged it. Runtime evidence mapped to process injection and LSASS-related activity, and multiple research rules matched, so it should not be trusted without source verification.

Where this verdict could be wrong4 caveats
  • tier1Malicious=0, while 14 tier-1 engines including BitDefender, ESET-NOD32, Kaspersky, and Fortinet reported no detection.
  • behaviour.hasMaliciousSandboxVerdict=false and droppedChildren.hasMaliciousChild=false, although the 10 inspected children all remain unclassified.
  • The disclosed YARA rules include Detect_PyInstaller and PyInstaller, which identify packaging technology and are not independently proof of malware.
  • The five similar-hash results are imphash-only matches without signer co-matching, so shared build tooling may account for the similarity.

These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.

Recommended action

Quarantine the executable pending verification from an official publisher or release channel, and avoid entering credentials or granting elevated privileges. Keep antivirus and endpoint protection enabled.

What this file does

Observed actions and their security significance

  • High concern: Injected code into another process, a technique that can conceal execution.

  • High concern: Encrypted files or data, behaviour commonly associated with ransomware.

  • High concern: Manipulated how the operating system loads code, which can redirect execution.

  • Moderate concern: Contained obfuscated or packed code that makes inspection harder.

  • Moderate concern: Runs hidden system commands (script or shell).

  • Moderate concern: Removed execution artefacts or logs, which can conceal activity.

  • Moderate concern: Communicated over a common application protocol; malware can use this for command-and-control.

These are observed capabilities from an isolated analysis. A technique does not prove malicious intent on its own, and the file never ran on your device.

What to do now

We couldn't fully clear this file. Treat it with caution.

  1. Recovery step 01

    Don't run it unless you're certain it came from a source you trust.

  2. Recovery step 02

    Check where you got it — an unexpected attachment or a random download link is a red flag.

  3. Recovery step 03

    If its origin cannot be confirmed, delete this file and use a fresh copy from a trusted source. Get a fresh copy from the developer's official site or an official app store.

  4. Recovery step 04

    If you're still unsure, scan it again in a day or two — detections often catch up on newer files.

8 evidence-based answers
Is NepTunnel 2.2.exe safe, or is it malware?
Evidence-based answer
NepTunnel 2.2.exe is suspicious — treat it as unsafe until you're sure. 5 of 74 antivirus engines flag it; that detection signal contributes to the cautious verdict. Don't run it unless you fully trust where it came from. Get a fresh copy from the developer's official site or an official app store.
What is NepTunnel 2.2.exe?
Evidence-based answer
NepTunnel 2.2.exe is a Windows executable program, about 19.1 MB. We identify a file by its cryptographic hash rather than its name, because the same filename can be reused by completely different files — the hash below is the reliable fingerprint.
How many antivirus engines detected NepTunnel 2.2.exe?
Evidence-based answer
5 of 74 antivirus engines flagged NepTunnel 2.2.exe, 5 of them as outright malicious. The raw count alone does not establish safety or danger; we also weigh which engines flagged it and corroborating behavior, identity, reputation, and rule evidence.
What should I do if I already ran NepTunnel 2.2.exe?
Evidence-based answer
Act quickly. 1) Disconnect the device from the internet to stop the malware communicating or spreading. 2) Run a full scan with reputable anti-malware software (such as Malwarebytes) and quarantine everything it finds. 3) Change your important passwords from a DIFFERENT, clean device — many threats log keystrokes or steal saved credentials. 4) If you bank or shop on this device, watch closely for fraud and alert your bank. 5) For a confirmed infection, the most reliable fix is to back up your personal files and reinstall the operating system for a clean start.
How do I remove NepTunnel 2.2.exe?
Evidence-based answer
To remove NepTunnel 2.2.exe: 1) restart into Safe Mode (Safe Mode with Networking if you need to download a tool) so the malware doesn't auto-start. 2) Run a full scan with reputable anti-malware software and let it quarantine or delete the detections. 3) Delete this file from the device, then empty the Recycle Bin or Trash. 4) Check your browser extensions, startup items, and scheduled tasks for anything unfamiliar. 5) Reboot and scan again to confirm it's gone. If detections keep coming back, a clean operating-system reinstall is the most dependable cure.
What kind of malware is NepTunnel 2.2.exe?
Evidence-based answer
NepTunnel 2.2.exe is classified as adware or a potentially unwanted program (PUA) — not always destructive, but it bundles ads, trackers, or unwanted changes you didn't ask for. Knowing the family matters because it tells you the likely impact — data theft, remote control, file encryption, or unwanted ads — and guides the cleanup.
What is the SHA-256 hash of NepTunnel 2.2.exe?
Evidence-based answer
The SHA-256 hash of NepTunnel 2.2.exe is 41b01a63bcb94d3466ada5e9df375ab92cd777377270aebd09597740bc9f2402, and its MD5 is 271d8a10cd69696c2a3f8369893a1ca4. This hash is the file's unique fingerprint — two files with the same SHA-256 are identical. Use it to confirm you're looking at exactly this file (not just one with the same name) when comparing against antivirus databases or a download's published checksum.
How up to date is this analysis of NepTunnel 2.2.exe?
Evidence-based answer
This report reflects the scan run on September 21, 2026. Because a file's hash never changes, the identity of NepTunnel 2.2.exe is fixed — but antivirus coverage improves over time, so a file that looks clean today can pick up detections later (and vice-versa). If you need the latest picture, MalwareTips staff can re-run the analysis from scratch.
