Is Setup.exe safe?
Only 3 of 75 engines flagged this unsigned installer, but observed process-injection and LSASS-targeting indicators justify caution pending source verification.
The antivirus picture is mostly reassuring: 3 of 75 engines flagged the file, with no tier-1 detections or agreed malware family. However, one runtime record maps activity to process injection and LSASS access, and the direct-IP contact was not fully reputation-checked, so the installer should not be trusted without verifying its source.

Before installing
Do not install it until the source and publisher can be verified independently.
If you already installed it
Stop using it, scan the device, and watch for unexpected behavior or security alerts. Download a fresh installer from the developer's official site or an official app store.

The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
The antivirus picture is mostly reassuring: 3 of 75 engines flagged the file, with no tier-1 detections or agreed malware family. However, one runtime record maps activity to process injection and LSASS access, and the direct-IP contact was not fully reputation-checked, so the installer should not be trusted without verifying its source.
Three of 75 engines detected the sample, while all 17 reporting tier-1 engines returned no detection. The labels are generic or weakly corroborated, so they do not establish a malware family. Runtime evidence nevertheless includes T1055 process injection, T1485, and reported LSASS-targeting activity, which are materially concerning for an installer. The executable is unsigned, and the reputation of its direct-IP contact was not completely checked. One sandbox returned a clean result and no inspected child was identified as malicious, leaving a mixed rather than conclusive evidence set.
What We Detected
Three of 75 antivirus engines flagged the executable. None of the 17 reporting tier-1 engines detected it, and the three labels do not form a reliable family consensus. The file is an unsigned Windows installer with no established publisher history.
Threat Behavior
One completed runtime observation mapped activity to T1055 process injection and T1485, while another heuristic identified process access targeting LSASS. The sample also contacted 162.159.36.2 directly, but no complete host-reputation result is available. The sandbox itself returned a clean result, and no inspected dropped child was identified as malicious, although all 10 child assessments remained inconclusive.
What To Do Now
Do not run the installer unless its download source and expected publisher can be independently verified. Keep endpoint protection enabled, and obtain a fresh copy from the software vendor's official release channel if the origin is uncertain.
Where this verdict could be wrong4 caveats
- All 17 reporting tier-1 engines were clean, and only 3/75 engines flagged the sample.
- behaviour.sandboxVerdicts records one clean result and behaviour.hasMaliciousSandboxVerdict=false.
- droppedChildren.hasMaliciousChild=false, although all 10 inspected children lack conclusive individual verdicts.
- peAnalysis.highEntropyCode=false and peAnalysis.likelyPacked=false provide no static packing indication.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- All 17 reporting tier-1 engines returned no detection
- Only 3 of 75 engines flagged the file
- One completed sandbox returned a clean verdict
- No inspected dropped child was identified as malicious
- No high-entropy code or likely packing was detected
- Unsigned Windows executable with no verified publisher identity
- Runtime evidence mapped to T1055 process injection
- Heuristic evidence reports LSASS-targeting activity
- T1485 appears among offensive runtime techniques
- Direct-IP contact to 162.159.36.2 lacks a completed reputation check
- Three antivirus detections, including VBA32's Trojan.Wacatac label
Quarantine the current copy until its origin and integrity are verified against an official vendor release. Keep antivirus and endpoint protection enabled while obtaining or testing any replacement.

What this file does
Observed actions and their security significance
High concern: Injected code into another process, a technique that can conceal execution.
High concern: Manipulated how the operating system loads code, which can redirect execution.
Moderate concern: Contained obfuscated or packed code that makes inspection harder.
Moderate concern: Removed execution artefacts or logs, which can conceal activity.
Moderate concern: Communicated over a common application protocol; malware can use this for command-and-control.
Moderate concern: Scans through your files and folders.
Note: Reads your Windows user-account details.
These are observed capabilities from an isolated analysis. A technique does not prove malicious intent on its own, and the file never ran on your device.

Signatures and behavior heuristics
A community signature or high-severity behavioral heuristic matched. Signatures identify known patterns; heuristics are strong leads but are not proof on their own.
The saved runtime evidence maps this activity to MITRE T1055 (Process Injection). The mapping supports possible process injection, but it does not prove the exact injection method or the operator's intent.
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.exeThe sample contacted an external IP address directly and no application domain was recorded. Direct-IP traffic also occurs in legitimate installers and infrastructure, so this is supporting context only and requires corroboration from host reputation and other runtime evidence.

What to do now
We couldn't fully clear this file. Treat it with caution.
- Recovery step 01
Don't install it unless you're certain it came from a source you trust.
- Recovery step 02
Check where you got it — an unexpected attachment or a random download link is a red flag.

If its origin cannot be confirmed, delete this file and use a fresh copy from a trusted source. Download a fresh installer from the developer's official site or an official app store.
- Recovery step 04
If you're still unsure, scan it again in a day or two — detections often catch up on newer files.
