Is ncNeL7MAc.exe safe?

Verdict
Malicious

Twenty-one of 75 engines flagged this newly observed executable, with multiple leading engines naming OfferCore and the Infivora signer showing a consistently harmful history.

Multiple independent engines identify this executable as an OfferCore bundler or unwanted downloader, including six high-trust detections. Its verified Infivora signature does not reduce concern because all seven historical samples from that signer were harmful, while runtime evidence includes process-injection mapping and LSASS-related activity.

Do not run this file

Keep endpoint protection enabled and quarantine or remove the file rather than launching it. If it already executed, run a full scan and inspect the system for unwanted software and account compromise.

This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.

Analyst conclusion

Multiple independent engines identify this executable as an OfferCore bundler or unwanted downloader, including six high-trust detections. Its verified Infivora signature does not reduce concern because all seven historical samples from that signer were harmful, while runtime evidence includes process-injection mapping and LSASS-related activity.

Where this verdict could be wrong4 caveats
  • signing.verified=true for 'Infivora', although signing.signerStats shows 7/7 malicious historical samples and trustedPublisher.matched=false.
  • behaviour.hasMaliciousSandboxVerdict=false; the single sandbox labeled the run clean despite recording T1055 and LSASS-related activity.
  • contactedHosts inspected the one distinct CloudFront host and found no known-malicious or suspicious host, while droppedChildren.hasMaliciousChild=false.
  • externalIntel.yaraify.ruleCount=0 and externalIntel.circl.hit=false provide no independent researcher-intelligence corroboration.

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

Keep endpoint protection enabled and quarantine or remove the file rather than launching it. If it already executed, run a full scan and inspect the system for unwanted software and account compromise.

What this file does

Observed actions and their security significance

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

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

  • 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.

  • Note: Reads your Windows user-account details.

  • Note: Collects details about your system.

  • Note: Loads extra code modules while running.

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.

Threat context

How bundlers & adware work

This is a bundler — a real-looking installer that hides extra software inside. When you run it, it quietly installs things you never asked for: ad injectors, browser toolbars, fake 'PC cleaner' apps, or even more bundlers. The people behind it get paid for every unwanted app they sneak on.

Bottom line:It's not usually built to destroy files, but it slows your PC, floods it with ads, and can be a real pain to fully remove.

What to do now

This file is dangerous. Treat it as harmful and remove it.

  1. Recovery step 01

    Don't run this file. Delete this file from the device, then empty the Recycle Bin or Trash.

  2. Recovery step 02

    If you already ran it, disconnect from the internet and start with a full antivirus scan or Microsoft Defender Offline scan. If compromise is suspected or the problem persists, use a reputable second-opinion scanner and follow incident-recovery or clean-reinstall guidance.

  3. Recovery step 03

    If you typed any passwords while it was open, change them from a device you trust.

  4. Recovery step 04

    Get a fresh copy from the developer's official site or an official app store.

9 evidence-based answers
Is ncNeL7MAc.exe a virus?
Evidence-based answer
Yes — ncNeL7MAc.exe is malicious. Do not run it. Delete this file from the device, then empty the Recycle Bin or Trash. 21 of 75 antivirus engines flag it (family: OfferCore). It behaves as adware or a potentially unwanted program (PUA) — not always destructive, but it bundles ads, trackers, or unwanted changes you didn't ask for. If you've already run it, see the removal and recovery steps below.
What is ncNeL7MAc.exe?
Evidence-based answer
ncNeL7MAc.exe is a Windows executable program, about 15.4 MB. Our analysis identifies it as malicious (family: OfferCore) — adware or a potentially unwanted program (PUA) — not always destructive, but it bundles ads, trackers, or unwanted changes you didn't ask for. Because a file's name and icon can be faked, the safest way to identify it is by its cryptographic hash (below), not its filename.
How many antivirus engines detected ncNeL7MAc.exe?
Evidence-based answer
21 of 75 antivirus engines flagged ncNeL7MAc.exe, 21 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. The malicious verdict comes from the complete saved evidence, not from this antivirus count by itself.
What should I do if I already ran ncNeL7MAc.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 ncNeL7MAc.exe?
Evidence-based answer
To remove ncNeL7MAc.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 ncNeL7MAc.exe?
Evidence-based answer
ncNeL7MAc.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. Engines attribute it to the OfferCore family. Knowing the family matters because it tells you the likely impact — data theft, remote control, file encryption, or unwanted ads — and guides the cleanup.
Is ncNeL7MAc.exe digitally signed?
Evidence-based answer
Yes — ncNeL7MAc.exe carries a valid digital signature from Infivora, which confirms the file hasn't been tampered with since that publisher signed it. A valid signature is a positive signal, but note that malware is occasionally signed with stolen or abused certificates, so it isn't proof of safety on its own.
What is the SHA-256 hash of ncNeL7MAc.exe?
Evidence-based answer
The SHA-256 hash of ncNeL7MAc.exe is c37ad5bdbb44f1af0b1fc7223c07fcee1a9d71d13a326bde5c006916771896fd, and its MD5 is ef2cedb0475a48e9ffdecff9d9601c56. 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 ncNeL7MAc.exe?
Evidence-based answer
This report reflects the scan run on September 29, 2026. Because a file's hash never changes, the identity of ncNeL7MAc.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.
