Is setup.exe safe?
Only 3 of 75 engines flagged this unsigned installer, but observed injection-related techniques and contact with a suspicious repack site warrant caution.
Most antivirus engines, including all 17 reporting tier-1 products, did not detect this installer, and no confirmed malware family emerged. However, it is unsigned and packed, one sandbox mapped activity to injection-related techniques, and it contacted a suspicious repack site, so execution is not recommended without verifying the source.
5f2fa50a3899a74693…f125132434290fRecommended next actions
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.
Most antivirus engines, including all 17 reporting tier-1 products, did not detect this installer, and no confirmed malware family emerged. However, it is unsigned and packed, one sandbox mapped activity to injection-related techniques, and it contacted a suspicious repack site, so execution is not recommended without verifying the source.
Three of 75 engines raised detections, led by Malwarebytes identifying crack-related riskware; the other labels were generic. All 17 reporting tier-1 engines were clean, and the sandbox did not issue a malicious runtime conclusion. Nonetheless, the executable is unsigned and packed, and runtime evidence mapped activity to T1055.011 and T1134. The host cross-check covered all 21 distinct contacts and found no complete contacted-host reputation result was available, but it did identify the repack site as suspicious. The sample's long history and broad prevalence reduce the likelihood of an undiscovered conventional trojan, while its crack/repack context and injection-related behavior still make it unsuitable for routine installation.
What We Detected
Three of 75 antivirus engines flagged the executable. Malwarebytes identified it as RiskWare.Crack, while the other two detections were generic; all 17 reporting tier-1 engines remained clean and there was no shared malware-family identification.
Threat Behavior
One completed sandbox run mapped activity to T1055.011 and T1134, which are associated with injection and token manipulation. The installer is unsigned and packed with an Inno-based appended payload, increasing uncertainty, although the sandbox supplied no malicious verdict and recorded no persistence indicators. All 21 distinct observed contacts were cross-checked: none were known malicious, but the repack site was marked suspicious. Ten dropped files were inspected without a malicious child being identified, though their individual verdicts remained unknown.
What To Do Now
Avoid running this copy unless its hash can be verified against a legitimate publisher or trusted distribution channel. Prefer an official, licensed installer, keep endpoint protection enabled, and remove this file if its origin cannot be authenticated.
Where this verdict could be wrong4 caveats
- All 17 reporting tier-1 engines were clean, and no engine family consensus developed.
- behaviour.hasMaliciousSandboxVerdict=false, droppedChildren.hasMaliciousChild=false, and externalIntel.yaraify.ruleCount=0.
- The sample is common and old, with prevalence.uniqueSources=408 and prevalence.timesSubmitted=491 since 2019.
- The only tier-2 detection is Malwarebytes RiskWare.Crack, which indicates potentially unwanted crack-related software rather than a confirmed malware family.
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 were clean
- No malicious sandbox verdict
- no complete contacted-host reputation result was available among 21 inspected contacts
- No malicious dropped child identified
- Common, long-observed sample with 408 sources and 491 submissions
- Unsigned Windows executable
- Packed Inno installer with appended content
- Sandbox-mapped T1055.011 and T1134 activity
- Contact with fitgirl-repacks.site, marked suspicious
- Malwarebytes RiskWare.Crack detection
- All 10 dropped-child verdicts remain unknown
Do not execute this copy unless its source and hash can be independently authenticated. Obtain the software from an official licensed channel and keep endpoint protection enabled.

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: Used an input-capture technique that can record credentials or keystrokes.
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: 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.
Evidence"C:\Users\<USER>\Desktop\program.exe"Unsigned, 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
Widely seen in the wild for a long time. High prior this is legitimate; isolated detections on common-old files are usually false positives.

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.
- Recovery step 03
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.
