Suspicious
Zero engine detections but sandbox reports and MITRE techniques show process injection and direct-IP activity.
6a245b728c63e1cb7c…373f310e33The 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.
The file is a signed Windows Installer with common_old prevalence and zero malicious engine detections. Sandbox behaviour includes six offensive MITRE techniques and direct-IP C2, while triggered heuristics explicitly call out process injection and credential-dumping patterns. No tier-1 consensus, no malicious children, and no external intel hits exist. The combination of clean engine results against concrete behavioural red flags produces mixed signals that prevent a clean safe or malicious determination.
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: Records what you type — keylogger behaviour.
High concern: Talks to a remote server to take commands or send out your data.
High concern: Can spread through USB and removable drives.
High concern: Installs itself as a Windows service to stay running.
High concern: Sets itself to run automatically every time you start your PC.
High concern: Tries to disable or bypass your security software.

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.

YARA & heuristic rule matches
A researcher-curated or high-severity heuristic rule matched this sample. These rules target specific malware families and are near-definitive.
MITRE T1055 (Process Injection) observed — CreateRemoteThread / APC / reflective-DLL injection. The payload is being smuggled into a legitimate process to bypass AV hooks.
EvidenceC:\Windows\System32\svchost.exe -k NetworkService -pSandbox observed process activity targeting LSASS (Windows credential store). Legitimate software has no business reading LSASS memory — this is Mimikatz-shape behaviour.
EvidenceC:\Windows\system32\lsass.exeSample contacted 8 external IP address(es) and zero domains. 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.

How widely this file has been seen
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 TestReach-6.2.0.msi, answered from the scan data above.
- TestReach-6.2.0.msi 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.
- TestReach-6.2.0.msi is a software installer, about 60.9 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 TestReach-6.2.0.msi 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 TestReach-6.2.0.msi: 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 TestReach-6.2.0.msi 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.
- Yes — TestReach-6.2.0.msi carries a valid digital signature from TestReach 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 TestReach-6.2.0.msi is 6a245b728c63e1cb7c5a37958bad2f30556d451468b450b9a444ff373f310e33, and its MD5 is 47738dd90f3af440c055c644937227c1. 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 12, 2026. Because a file's hash never changes, the identity of TestReach-6.2.0.msi 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.
