Before running
Do not run it until the source and publisher can be verified independently.
If you already ran it
Stop using it, scan the device, and watch for unexpected behavior or security alerts. Get a fresh copy from the developer's official site or an official app store.
Intelligence
The saved assessment, checked against the scan evidence and recorded coverage.
No saved analyst narrative
This report keeps the verified scan facts available below without inventing an analysis that was not saved with the scan.
Coverage & freshness
Complete means the check returned a usable result. It does not mean the file is safe.
Antivirus
Complete1 of 73 engines flagged the file.
Sandbox
Complete1 isolated runtime environment contributed observations.
Network
Partial1 of 7 contacted hosts were cross-checked; coverage is incomplete.
YARA
Complete2 signature or behavior rules matched.

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: Created or modified a system service, which can keep code running.
High concern: Changed an auto-start location that can make code run after sign-in or restart.
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).
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.
MITRE T1055 (Process Injection) observed — CreateRemoteThread / APC / reflective-DLL injection. The payload is being smuggled into a legitimate process to bypass AV hooks.
Evidence%SAMPLEPATH%\4ffc6e789f9f35d313ef3ed75b44bab98240da082a0f700a3ab99d951b931df3.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.

Section entropy & packers
No high-entropy executable section or known packer signature was detected. Data and resource sections can still have high entropy without indicating packed code.
How widely this file has been seen
Rarely uploaded, but has been around for a while. Often niche legitimate software or old internal tooling; not a strong malware signal on its own.
