Verdict Suspicious
Is Setup. exe safe? Treat it as suspicious.
One less reliable engine flags Trojan.Zenpak while 16 major antivirus engines report clean.
Why Suspicious? One antivirus engine (Jiangmin) flags it; nothing else confirms it.
Limited evidence · One sign points to a problem; nothing else confirms it.
Treat as suspicious pending further sandbox or manual analysis; avoid execution until additional confirmation is obtained.
What to do now4 steps
Some signs point to a problem, but nothing confirms it is harmful. Treat it with caution.
What to do
Don't install it unless you're sure where it came from.
Check where you got it: an unexpected attachment, a link someone sent you or a re-upload is a red flag.
If you can't confirm where it came from, delete it. If you need the program, download it again from the publisher's own website.
If you already installed it
Stop using it, run a full scan with your antivirus and watch for unexpected behavior or security alerts.

Why we think so
2 points against it and 3 in its favour, checked against the scan evidence.
The reasoning behind this verdict
Prevalence is widely seen and long established but behaviour raises red flags on an otherwise quiet sample.
The file is a 4 MB signed EXE submitted on Sep 7, 2023 with widely seen and long established prevalence. Engines show only a single less reliable detection and no major consensus. No complete contacted-host reputation result was available, and no external intel hits. The combination of clean engine majority and suspicious activity in the test run places the file in mixed-signals territory.
What We Detected
71 engines scanned the sample; only Jiangmin returned a malicious label (Trojan.Zenpak.oyd). All 16 major antivirus engines reported clean. The binary is signed by Kaspersky Lab JSC but carries no established signer history in our records. Sandbox execution revealed MITRE T1055 (process injection) and T1562.001 (impair defenses) plus access to the Windows password store and 18 direct-IP connections with zero DNS lookups.
Threat Behavior
Multiple dropped files and temporary directories were created during execution, consistent with an installer or downloader. No malicious files it created or known-bad hosts were observed.
What To Do Now
Do not execute on production systems. Submit the sample to additional sandboxes or threat-intel platforms for deeper behavioural analysis. Monitor for similar hashes or the listed contacted IPs.
Where this verdict could be wrong1 caveat
- Community comment lists unrelated families (#amadey etc.) with no engine or YARA corroboration — likely noise rather than confirmation.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- 16 major antivirus engines reported clean
- Common_old prevalence across 191 sources
- No malicious files it created or cached malicious hosts
- Direct-IP a control server with no DNS resolution
- Less reliable engine detection of Zenpak family

What the test run showed
What the file did on a test computer
Confirmed in the test run
Moderate concern: Contains packed or scrambled code that is harder to inspect (common in installers too).
Moderate concern: Used an unusual way to talk to a server.
Moderate concern: Downloaded a file during the test run.
Moderate concern: Checked whether it was running on a test computer.
Note: Listed the programs running on the test computer.
Note: Deleted files or logs during the test run (installers often clean up after themselves).
Note: Talked to servers over the internet during the test run.
Sandbox labels we could not confirm (common in safe files too)
Not confirmed: A sandbox rule tagged this run as creating a scheduled task; none was recorded.
Not confirmed: A sandbox rule tagged this run as code injection, but no injected program was recorded.
Not confirmed: A sandbox rule tagged this run as weakening security settings; no setting change was recorded.
This file was run on a test computer (a sandbox), not on yours. Labels we could not confirm are listed so you can see them, but they are not treated as evidence against the file.
