Is setup.exe safe?
Unsigned installer with process-injection and LSASS-access behaviour plus one tier-1 crack-family detection.
Four engines flag the file, one of them tier-1, naming a crack/PSEB family. Sandbox shows process injection and LSASS access. Similar imphash samples have been labelled malicious or suspicious as crack tools.

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.
Intelligence
The saved assessment, checked against the scan evidence and recorded coverage.
The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
Four engines flag the file, one of them tier-1, naming a crack/PSEB family. Sandbox shows process injection and LSASS access. Similar imphash samples have been labelled malicious or suspicious as crack tools.
The single tier-1 detection and four low-to-medium offensive MITRE techniques outweigh the lack of sandbox malice verdict and absence of dropped malicious children. Unsigned status and prior imphash matches labelled crack reduce confidence in a clean classification. Medium prevalence and installer filename keep the file in mixed-signals territory rather than outright malicious.
What We Detected
Four of 73 engines flagged the sample. GData (tier-1) labelled it Generic.Trojan.PSEB.IVLRDN; Malwarebytes labelled it RiskWare.Crack. The file is an unsigned 5.4 MB Win32 EXE with an Inno Setup-style installer hint.
Threat Behavior
Runtime evidence shows four offensive MITRE techniques: T1055 (process injection), T1134 (token manipulation), T1485 (data destruction), and T1548 (privilege escalation). The sandbox observed activity targeting LSASS and direct-IP contact to 162.159.36.2. Ten dropped children were inspected; none carried malicious verdicts.
What To Do Now
Do not execute the file. Keep Windows Defender and other endpoint protection enabled. If the file was downloaded from an untrusted source, delete it and scan the system with current signatures.
Where this verdict could be wrong2 caveats
- engines.tier1Malicious=1 and tier1FamilyConsensus.strong=false — only one high-trust engine
- droppedChildren.hasMaliciousChild=false and 10 children inspected with no malicious verdicts
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- Only one tier-1 engine flagged
- No malicious dropped children
- No sandbox malicious verdict
- Unsigned executable
- Process injection observed
- LSASS access observed
- Tier-1 crack-family detection
- Prior imphash matches labelled malicious
Treat the file as suspicious; avoid execution and delete it unless a trusted publisher can supply a signed 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: Runs hidden system commands (script or shell).
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.
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\Explorer.EXESandbox 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.
