Is FNP1119.dll safe?
Unsigned 64-bit DLL with four tier-1 detections and observed process-injection behaviour but no sandbox malice or strong family consensus.
19 of 75 engines flag the file, four of them tier-1, citing Themida packing and generic trojan labels. The DLL is unsigned, shows T1055 process injection in sandbox traces, yet the single sandbox run returned no malicious verdict and twelve tier-1 engines stayed silent.

Before using
Do not use it until the source and publisher can be verified independently.
If you already used it
Stop using it, scan the device, and watch for unexpected behavior or security alerts. Reinstall the parent software from the developer's official site instead of replacing this component by itself.
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.
19 of 75 engines flag the file, four of them tier-1, citing Themida packing and generic trojan labels. The DLL is unsigned, shows T1055 process injection in sandbox traces, yet the single sandbox run returned no malicious verdict and twelve tier-1 engines stayed silent.
The combination of tier-1 detections, offensive MITRE techniques, and lack of code signing places the sample in mixed-signal territory. Absence of a strong tier-1 family consensus, no malicious sandbox verdict, and incomplete host-reputation data prevent a definitive malicious call. Medium prevalence and no prior similar-hash verdicts add no additional weight either direction.
What We Detected
Four tier-1 engines (ESET-NOD32, Fortinet, Sophos, Symantec) and fifteen additional engines labelled the 5.6 MB Win32 DLL malicious or suspicious. Labels reference Themida packing, Wacapew, and generic trojan or PUA categories. The file is unsigned and contains high-entropy sections consistent with obfuscation.
Threat Behavior
Sandbox execution recorded rundll32 invocation of the DLL export and mapped activity to MITRE T1055 (process injection), T1548, and T1562.001. no complete contacted-host reputation result was available were contacted, no malicious child files were dropped, and the sandbox itself did not return a malicious verdict.
What To Do Now
Do not load the DLL in production environments. Keep endpoint protection enabled and submit the sample to your security vendor for further analysis if it appears in your environment.
Where this verdict could be wrong2 caveats
- engines.tier1Clean=12 and tier1Malicious=4 — majority of tier-1 engines did not flag the sample.
- sandboxVerdicts empty and hasMaliciousSandboxVerdict=false despite one sandbox execution.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- Twelve tier-1 engines reported clean
- No malicious sandbox verdict
- No malicious dropped children
- Unsigned DLL
- Four tier-1 malicious detections
- Observed T1055 process-injection behaviour
Treat the DLL as untrusted; block or sandbox it until additional vendor analysis is available.

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: Attempted to impair or bypass security controls.
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: 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.

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.

What to do now
We couldn't fully clear this file. Treat it with caution.
- Recovery step 01
Don't use 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
Do not delete or replace the component manually. Quarantine it with your antivirus or repair the parent software from its official source. Reinstall the parent software from the developer's official site instead of replacing this component by itself.
- Recovery step 04
If you're still unsure, scan it again in a day or two — detections often catch up on newer files.
