Is spotifast-v0.12.0-x86_64-pc-windows-msvc-setup.exe safe?
Three generic detections and concerning runtime mappings warrant caution, although tier-1 engines, the sandbox verdict, and external intelligence provide no malware-family confirmation.
Only 3 of 75 engines flagged this unsigned installer, and none of the 17 tier-1 engines detected it. However, one runtime report mapped activity to process injection and destructive-impact techniques, while the direct-IP contact lacks a completed reputation check, so execution should be deferred pending publisher verification.

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.
Only 3 of 75 engines flagged this unsigned installer, and none of the 17 tier-1 engines detected it. However, one runtime report mapped activity to process injection and destructive-impact techniques, while the direct-IP contact lacks a completed reputation check, so execution should be deferred pending publisher verification.
The antivirus result is weakly concerning: 3 of 75 engines flagged the sample, but none were tier-1 and no named family consensus exists. Runtime evidence maps activity to T1055, T1485, and T1486, though the single sandbox verdict was clean and did not observe persistence. The executable is unsigned and only three days old, leaving no authenticated publisher or signer history to offset those concerns. Four prior malicious results share its imphash, but they involve different signed files and therefore may reflect a common installer framework rather than shared payload code. The recorded IP contact was not fully reputation-checked, and no independent YARA, malware-database, or malicious-child corroboration was found.
What We Detected
Three of 75 antivirus engines flagged the installer. DeepInstinct and APEX used generic malicious labels, while Skyhigh reported BehavesLike.Win32.ObfuscatedPoly.wc; all 17 tier-1 engines reported no detection, so there is no strong family consensus.
Threat Behavior
One completed sandbox mapped activity to T1055, T1485, and T1486, including possible process injection and destructive-impact capabilities. These mappings are concerning but do not establish intent by themselves; the same run returned a clean sandbox verdict, observed no persistence indicators, and found no confirmed malicious child among 10 inspected files. The sample contacted 162.159.36.2 directly, but no complete host-reputation result is available.
What To Do Now
Do not run the installer on a production system until its source and publisher can be independently verified. Keep endpoint protection enabled, obtain the installer from the project's official release channel, and compare its SHA-256 value before considering isolated testing.
Where this verdict could be wrong4 caveats
- All 17 reporting tier-1 engines were silent, and only 3/75 engines produced generic detections.
- The completed sandbox assigned a clean verdict, found no persistence indicators, and droppedChildren.hasMaliciousChild=false after inspecting 10 children, although all child verdicts remained unknown.
- The file has 249 submitting sources and 260 submissions despite being only three days old, which is broader distribution than a one-off sample.
- No MalwareBazaar or YARAify match was found, but absence of external-intelligence hits does not establish benignity.
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 tier-1 engines reported no detection
- The only completed sandbox returned a clean verdict
- No persistence indicators were recorded
- No confirmed malicious child among 10 inspected files
- No MalwareBazaar or YARAify hit, and PE analysis found no likely packing
- Unsigned Windows executable with no established signer history
- Three offensive technique mappings: T1055, T1485, and T1486
- Direct contact with 162.159.36.2 without a completed host-reputation check
- Three generic antivirus detections among 75 engines
- Only three days since first observation
- Four malicious imphash-only historical matches, albeit without signer co-match
Avoid executing this build until its hash and release source are verified with the official publisher. Keep security protection enabled and use an isolated environment if further testing is necessary.

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: Encrypted files or data, behaviour commonly associated with ransomware.
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: Checked the environment for virtualisation or analysis tools.
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.

Detection sources at a glance
The available sources did not agree on a named threat category.
MalwareBazaar, YARAify, and CIRCL hashlookup completed and returned no entries for this hash.
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.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.
