Suspicious
Zero AV detections but imphash matches known OfferCore PUA samples and sandbox shows process injection plus LSASS access.
4a6d77f023c0209a39…14c10caa16The reasoning behind this verdict
The MT AI Engine weighs every signal from this scan — antivirus detections, sandbox behaviour, code signing, prevalence and historical matches — to reach a single, evidence-based verdict.
All 74 engines returned clean results, including 17 tier-1 engines, which normally supports a safe verdict. However the imphash matches four prior malicious OfferCore verdicts and the sandbox captured process injection plus LSASS access. Five YARAify rules also fired on injection and TLS anomalies. The combination of clean engines against strong behavioural and RAG signals produces a borderline mixed picture.
Each signal cites a concrete token from the evidence the arbiter saw — engine name, MITRE technique, signer string, or an exact count.

What this file does
What it attempted when executed in an isolated sandbox
High concern: Hides inside another running program to evade antivirus.
High concern: Talks to a remote server to take commands or send out your data.
Moderate concern: Obfuscates or packs its code to avoid detection.
Moderate concern: Deletes traces of itself to cover its tracks.
Note: Reads your Windows user-account details.
Note: Collects details about your system.
Note: Loads extra code modules while running.

What to do now
We couldn't fully clear this file. Treat it with caution.
Don't run it unless you're certain it came from a source you trust.
Check where you got it — an email attachment or a random download link is a red flag.
If you're unsure, delete it. You can always re-download a clean copy from the official source.
If you're still unsure, scan it again in a day or two — detections often catch up on newer files.

Safety FAQ
Common questions about audacity-win-3.7.8-64bit.exe, answered from the scan data above.
- audacity-win-3.7.8-64bit.exe is suspicious — treat it as unsafe until you're sure. 0 of 74 antivirus engines flag it (family: offercore), which isn't a strong consensus but is enough to be cautious. Don't run it unless you fully trust where it came from, and prefer downloading the software fresh from its official site.
- audacity-win-3.7.8-64bit.exe is a Windows executable program, about 19.5 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.
- None — all 74 antivirus engines we queried report audacity-win-3.7.8-64bit.exe as clean. That's reassuring, though brand-new malware can briefly evade detection before vendors add signatures, so we also weigh the file's behaviour and reputation.
- 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.
- To remove audacity-win-3.7.8-64bit.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 the original audacity-win-3.7.8-64bit.exe file and empty the Recycle Bin/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.
- audacity-win-3.7.8-64bit.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.
- Yes — audacity-win-3.7.8-64bit.exe carries a valid digital signature from MuseCY SM Ltd, 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.
- The SHA-256 hash of audacity-win-3.7.8-64bit.exe is 4a6d77f023c0209a396fcf2f3c7c04e240b6ba9897b3231a6ed18e14c10caa16, and its MD5 is 21a5d2183e0a7e3552bb686872b7312b. 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.
- This report reflects the scan run on July 17, 2026. Because a file's hash never changes, the identity of audacity-win-3.7.8-64bit.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.
