Suspicious
Unsigned installer with process-injection indicators, direct-IP contacts, and two YARA matches but zero AV detections.
8b1158f6552a30da70…edbb8a222eThe verdict, reasoned out.
Not a rules engine. The MT AI Engine reads every signal we collected, weighs them against history, and commits to an answer.
Zero malicious detections from all engine tiers including 17 tier-1 engines points away from known malware. However, the sandbox recorded five offensive MITRE techniques, direct-IP contacts without DNS, and two YARA rules explicitly targeting obfuscation and generic RAT behaviour. The file is unsigned with no signer history, and adversarial comment injection was flagged. While prevalence is high and one imphash-similar file was previously marked safe, the behavioural and YARA evidence outweighs the clean engine results.
Each signal cites a concrete token from the evidence the arbiter saw — engine name, MITRE technique, signer string, or an exact count.

MITRE T1055 (Process Injection) observed — CreateRemoteThread / APC / reflective-DLL injection. The payload is being smuggled into a legitimate process to bypass AV hooks.

Benign software virtually always uses DNS; no-DNS direct-IP C2 is a strong malware indicator because it bypasses reputation systems and dodges domain-based blocklists.

Section entropy & packers
Section-level entropy and packer detection from the PE header. Nothing suspicious here — entropy is within the normal range for unpacked code.
How often this file shows up in the wild
Widely seen in the wild for a long time. High prior this is legitimate; isolated detections on common-old files are usually false positives.

Safety FAQ
Common questions about Mechvibes.Setup.2.3.4.exe, answered from the scan data above.
- Mechvibes.Setup.2.3.4.exe is suspicious — treat it as unsafe until you're sure. 0 of 74 antivirus engines flag it, 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.
- Mechvibes.Setup.2.3.4.exe is a Windows executable program, about 61.8 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 Mechvibes.Setup.2.3.4.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 Mechvibes.Setup.2.3.4.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 Mechvibes.Setup.2.3.4.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.
- The SHA-256 hash of Mechvibes.Setup.2.3.4.exe is 8b1158f6552a30da70aff106d4ab129e08980175e440c5945bb290edbb8a222e, and its MD5 is 2441bd745cfb0cbd39c806a475cc9bff. 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 11, 2026. Because a file's hash never changes, the identity of Mechvibes.Setup.2.3.4.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.
