Is setup.exe safe?
Two tier-1 detections, crack-related labeling, an unsigned publisher identity, and observed T1055/T1134 activity create substantial concern despite weak family agreement.
Seven of 74 engines flagged this unsigned installer, including GData and Microsoft, but they did not agree on one malware family. One sandbox run recorded techniques mapped to process injection and token manipulation, while producing no malicious sandbox verdict; avoid running the file unless its source and integrity 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.
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.
Seven of 74 engines flagged this unsigned installer, including GData and Microsoft, but they did not agree on one malware family. One sandbox run recorded techniques mapped to process injection and token manipulation, while producing no malicious sandbox verdict; avoid running the file unless its source and integrity can be independently verified.
Seven of 74 engines detected the sample, with two independent tier-1 products contributing materially stronger evidence than the three low-trust detections. GData named PSEB and Microsoft named Wacapew, so the detections lack the family agreement needed for a definitive named-family attribution. A completed sandbox run recorded T1055 and T1134, both offensive techniques, although the sandbox did not issue a malicious verdict or observe persistence. The executable is unsigned and lacks publisher history, which leaves no authenticated vendor identity to offset those signals. Malwarebytes' RiskWare.Crack label and the crack-related aggregate label support a PUA interpretation, but no hacktool confirmation exists. Similar files mostly received cautious assessments, though their imphash-only relationship may simply reflect a shared installer framework.
What We Detected
Seven of 74 antivirus engines flagged the executable. Two are tier-1 detections: GData reported Generic.Trojan.PSEB.L4Z8LK and Microsoft reported Program:Win32/Wacapew.C!ml. Malwarebytes additionally identified RiskWare.Crack, but the engines did not establish strong agreement on one family.
Threat Behavior
One completed sandbox run recorded behavior mapped to T1055 (Process Injection) and T1134 (Access Token Manipulation). No malicious sandbox verdict, persistence indicator, or network contact was recorded during that run. Six dropped files were inspected without a confirmed malicious child, but their individual verdicts remain unknown, and no complete contacted-host reputation result is available.
What To Do Now
Do not execute this installer on a production system. Keep endpoint protection enabled, obtain the software from its official publisher, and verify a trusted signature or publisher-provided hash before reconsidering it; if already run, isolate the device and perform a full security scan.
Where this verdict could be wrong5 caveats
- 15 of 17 tier-1 engines did not flag the sample, and engines.tier1FamilyConsensus.strong=false.
- behaviour.hasMaliciousSandboxVerdict=false, with no persistence indicators or observed network contacts in the single completed run.
- externalIntel.yaraify.ruleCount=0, externalIntel.circl.hit=false, and externalIntel.malwareBazaar.hit=false; these absences may reflect intelligence-coverage gaps.
- peAnalysis.highEntropyCode=false and peAnalysis.likelyPacked=false, so static PE analysis does not indicate packed executable code.
- droppedChildren.rollup reports six unknown children rather than confirmed clean children, although droppedChildren.hasMaliciousChild=false.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- 15 of 17 tier-1 engines did not flag the sample
- No strong tier-1 family consensus
- No malicious sandbox verdict in one completed run
- No confirmed malicious dropped child among six inspected hashes
- No YARAify, CIRCL, or MalwareBazaar intelligence hit
- 7/74 antivirus detections
- Two independent tier-1 detections from GData and Microsoft
- Unsigned Win32 executable with no signer history
- Sandbox-observed T1055 process-injection mapping
- Sandbox-observed T1134 access-token manipulation mapping
- Crack and riskware labeling
Quarantine the file and obtain a signed copy from the software publisher's official release channel. If it has already executed, keep security protection enabled, isolate the system, and run a full endpoint scan.

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: Runs hidden system commands (script or shell).
Moderate concern: Communicated over a common application protocol; malware can use this for command-and-control.
Moderate concern: Scans through your files and folders.
Moderate concern: Checked the environment for virtualisation or analysis tools.
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.
