Malicious
Signed MSI loader detected as ValleyRAT by multiple engines and community intel, with Defender tampering, process injection, and suspicious YARA hits confirming malicious loader behavior.
e17d12a3cb758a7cd5…bb91216fc4The 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.
A single tier-1 engine (Kaspersky) flags it as a loader alongside tier-2 ValleyRAT detection, bolstered by high-severity heuristics for Defender tampering and process injection. YARAify's 5 rule matches, including MSI LATAM Banker, align with community MalwareBazaar tagging as ValleyRAT. The clean tier-1 majority and lack of sandbox consensus provide some counterweight, but offensive MITRE techniques and direct IP contacts override. No signer history raises stolen certificate concerns for this new file.
Each signal cites a concrete token from the evidence the arbiter saw — engine name, MITRE technique, signer string, or an exact count.

Treat as confirmed malware: delete the file, run a full system scan with updated security software, and monitor for persistence from dropped files like GGSafe.exe. Avoid running disguised installers from untrusted sources.
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.
High concern: Can spread through USB and removable drives.
High concern: Tries to disable or bypass your security software.
Moderate concern: Lists running programs — often to find security tools.
Moderate concern: Runs hidden system commands (script or shell).
Moderate concern: Checks whether it's being watched in a sandbox before acting.
Translated from the file's technical behaviour during analysis. It never ran on your device.
Threat context
How remote-access malware works
This opens a secret 'back door' into your computer. Once it's running, an attacker can control your PC from anywhere — see your screen, read your files, switch on your webcam, install more malware, or use your machine to attack others.
Bottom line:It's built to stay hidden and keep that connection open for as long as possible.
What to do now
This file is dangerous. Treat it as harmful and remove it.
Don't open or run this file. Delete it from your Downloads (or wherever you saved it), then empty the Recycle Bin.
If you already opened it, disconnect from the internet and run a full scan with your antivirus — Windows Security, built into Windows, is sufficient.
If you typed any passwords while it was open, change them from a device you trust.
In future, only download software from the official website or an official app store.

Safety FAQ
Common questions about e17d12a3cb758a7cd55d9e0305bc1471d30a7125cb14f3574d47f1bb91216fc4.msi, answered from the scan data above.
- Yes — e17d12a3cb758a7cd55d9e0305bc1471d30a7125cb14f3574d47f1bb91216fc4.msi is malicious, so do not run it, and delete it. 4 of 75 antivirus engines flag it (family: ValleyRAT). It behaves as a backdoor/remote-access trojan that lets an attacker control the device remotely. If you've already run it, see the removal and recovery steps below.
- e17d12a3cb758a7cd55d9e0305bc1471d30a7125cb14f3574d47f1bb91216fc4.msi is a software installer, about 20.7 MB. Our analysis identifies it as malicious (family: ValleyRAT) — a backdoor/remote-access trojan that lets an attacker control the device remotely. 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.
- 4 of 75 antivirus engines flagged e17d12a3cb758a7cd55d9e0305bc1471d30a7125cb14f3574d47f1bb91216fc4.msi, 4 of them as outright malicious. A detection rate at this level is a reliable signal that the file is dangerous.
- 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 e17d12a3cb758a7cd55d9e0305bc1471d30a7125cb14f3574d47f1bb91216fc4.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 e17d12a3cb758a7cd55d9e0305bc1471d30a7125cb14f3574d47f1bb91216fc4.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.
- e17d12a3cb758a7cd55d9e0305bc1471d30a7125cb14f3574d47f1bb91216fc4.msi is classified as a backdoor/remote-access trojan that lets an attacker control the device remotely. Engines attribute it to the ValleyRAT 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 — e17d12a3cb758a7cd55d9e0305bc1471d30a7125cb14f3574d47f1bb91216fc4.msi carries a valid digital signature from MiniTool Software Limited, 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 e17d12a3cb758a7cd55d9e0305bc1471d30a7125cb14f3574d47f1bb91216fc4.msi is e17d12a3cb758a7cd55d9e0305bc1471d30a7125cb14f3574d47f1bb91216fc4, and its MD5 is 8a439d79b71266e40b932055916c0ce6. 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 April 28, 2026. Because a file's hash never changes, the identity of e17d12a3cb758a7cd55d9e0305bc1471d30a7125cb14f3574d47f1bb91216fc4.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.
