Is Setup.exe safe?
Three generic detections lack tier-1 support, but unsigned packing, possible process injection, LSASS-related activity, and unresolved direct-IP traffic warrant caution.
Only 3 of 75 engines raised generic alerts, with no tier-1 detection or agreed malware family. However, the unsigned packed installer produced telemetry associated with process injection and LSASS activity, then contacted a direct IP whose reputation was not checked completely; avoid running it unless its source and publisher can be independently verified.

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.
Only 3 of 75 engines raised generic alerts, with no tier-1 detection or agreed malware family. However, the unsigned packed installer produced telemetry associated with process injection and LSASS activity, then contacted a direct IP whose reputation was not checked completely; avoid running it unless its source and publisher can be independently verified.
The antivirus result is limited to 3 of 75 engines, and none of the detections came from a tier-1 engine or established a consistent family. That ordinarily points toward a possible false positive, particularly for an Inno Setup installer. The counterweight is completed runtime telemetry mapping activity to T1055 and surfacing LSASS-related process activity, both of which deserve investigation. The file is also unsigned and packed, and its direct-IP contact could not be fully reputation-checked because no complete contacted-host result is available. A clean sandbox label and no identified malicious child reduce confidence in a malware attribution, leaving materially conflicting evidence.
What We Detected
Three of 75 antivirus engines flagged the file. Skyhigh and Varist used generic obfuscation or cryptor-style labels, while APEX supplied a generic malicious label; no tier-1 engine detected it and no family consensus formed.
Threat Behavior
The completed sandbox run recorded activity mapped to MITRE T1055 and telemetry involving LSASS, which can be associated with process injection or credential access. The installer also contacted 162.159.36.2 directly. No complete contacted-host reputation result is available, so that no complete contacted-host reputation result was available or malicious from this evidence. The file is unsigned and appears packed with Inno Setup, although installer packing alone is common and not proof of wrongdoing.
What To Do Now
Do not launch the installer on a production system until its download source, expected publisher, and cryptographic hash can be verified through the software vendor. Keep endpoint protection enabled; if testing is necessary, use an isolated disposable environment with network monitoring and no sensitive credentials.
Where this verdict could be wrong4 caveats
- tier1Malicious=0, and 16 tier-1 engines reported no detection, substantially weakening the three generic engine alerts.
- behaviour.sandboxVerdicts[0].verdict='clean' and behaviour.hasMaliciousSandboxVerdict=false, although the saved telemetry still maps activity to T1055.
- droppedChildren.hasMaliciousChild=false, but the sole inspected child has no assigned verdict and remains unknown.
- externalIntel.yaraify.ruleCount=0 and externalIntel.malwareBazaar.hit=false; absence of these hits does not exclude an emerging or obscure threat.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- No tier-1 antivirus detections
- 16 tier-1 engines reported no detection
- No malicious sandbox verdict
- No identified malicious dropped child
- No MalwareBazaar or YARAify hit
- Unsigned Windows executable
- Likely packed Inno Setup installer
- Runtime telemetry mapped to MITRE T1055
- LSASS-related process activity
- Direct connection to 162.159.36.2 without complete reputation coverage
- Three generic antivirus detections
Quarantine the file pending source and publisher verification, and obtain a fresh installer directly from the vendor if possible. Keep endpoint protection enabled and avoid entering credentials on any system where this sample has run.

What this file does
Observed actions and their security significance
High concern: Injected code into another process, a technique that can conceal execution.
Moderate concern: Contained obfuscated or packed code that makes inspection harder.
Moderate concern: Communicated over a common application protocol; malware can use this for command-and-control.
Note: Reads your Windows user-account details.
Note: Collects details about your system.
Note: Loads extra code modules while running.
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.
Evidence162.159.36.2Unsigned, packed PE with sandbox-observed network activity. The packing step hides the payload until execution; the network call fetches / reports for the next stage. Classic dropper / stager behaviour.

Section entropy & packers
A known packer signature (UPX / Themida / VMProtect / etc.) matched this file. Packers aren't malicious on their own, but most malware uses them.
Packers compress or encrypt the executable and only unpack it at runtime. Legitimate commercial software uses them too — but if the file is also unsigned and rare, it's a strong malware signal.
How widely this file has been seen
Moderate prevalence — neither rare nor common. No strong prior applies.
