Why we think so
1 point against it and 4 in its favour, checked against the scan evidence.
The reasoning behind this verdict
This DLL behaves like a Fallout 4 Script Extender plugin: it exposes the standard plugin load, preload and version functions. None of the 70 antivirus engines that checked it flagged it, it is not packed, and the sandbox runs recorded no injection into other processes and no network activity of its own. It is unsigned, which is common for community game mods.
None of the 70 antivirus engines that checked it flagged the file, including all 18 major antivirus engines that reported on it. The sandbox runs show the DLL being loaded with rundll32 and its F4SE plugin functions being called, and the crash reports it produced are expected for a game plugin running outside the game. The file shows no packing or high-entropy code. It is unsigned with no publisher history, a typical gap for community mods but one that leaves authorship unconfirmed.
What We Detected
None of the 70 antivirus engines that checked it flagged this 64-bit DLL. Its sections show normal entropy with no packer. It exports F4SEPlugin_Load, F4SEPlugin_Preload and F4SEPlugin_Version, the interface used by Fallout 4 Script Extender plugins.
Threat Behavior
In the sandbox runs, the DLL was loaded through rundll32 and crashed. That is expected, because a game plugin needs the game process to run. No processes were injected into, no persistence was set, and the only network contact was the analysis machine's own background traffic. Several mapped techniques appeared without supporting artefacts. These mappings are common on legitimate software.
What To Do Now
Obtain the mod from its official mod page and keep your antivirus enabled. The file is unsigned, so confirm that it came from a trusted mod source.
Where this verdict could be wrong2 caveats
- The DLL is unsigned and has no publisher history, so its authorship cannot be confirmed from a signature.
- No complete host-reputation result or external intelligence lookup is available for this file.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- None of the 70 antivirus engines that checked it flagged the file.
- It exposes standard Fallout 4 Script Extender plugin functions, matching its stated purpose.
- No packing or obfuscated code sections.
- No injection into other processes, no persistence and no network activity of its own were recorded.
- The DLL carries no digital signature, so its author cannot be verified.
