Verdict
Suspicious

Unsigned 64-bit DLL flagged by one tier-1 engine as GameHack with observed process-injection behaviour.

Four of 75 engines flagged the file, one of them tier-1. The DLL is unsigned, executed via rundll32, performed process injection (T1055), and contacted two direct IPs. No sandbox verdict or known-malicious hosts were recorded.

Do not use it until verified

Treat the file as untrusted; obtain a signed copy from the legitimate vendor or remove it.

01

Before using

Do not use it until the source and publisher can be verified independently.

02

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.

Analyst conclusion

Four of 75 engines flagged the file, one of them tier-1. The DLL is unsigned, executed via rundll32, performed process injection (T1055), and contacted two direct IPs. No sandbox verdict or known-malicious hosts were recorded.

Where this verdict could be wrong1 caveat
  • contactedHosts.inspected=1 but only covers one of the two observed IPs; no complete host-reputation result available.

These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.

Recommended action

Treat the file as untrusted; obtain a signed copy from the legitimate vendor or remove it.

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: Runs hidden system commands (script or shell).

  • Moderate concern: Communicated over a common application protocol; malware can use this for command-and-control.

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.

What to do now

We couldn't fully clear this file. Treat it with caution.

  1. Recovery step 01

    Don't use it unless you're certain it came from a source you trust.

  2. Recovery step 02

    Check where you got it — an unexpected attachment or a random download link is a red flag.

  3. 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.

  4. Recovery step 04

    If you're still unsure, scan it again in a day or two — detections often catch up on newer files.

8 evidence-based answers
Is d3d11.dll safe, or is it malware?
Evidence-based answer
d3d11.dll is suspicious — treat it as unsafe until you're sure. 4 of 75 antivirus engines flag it (family: gamehack); that detection signal contributes to the cautious verdict. Don't use it unless you fully trust where it came from. Reinstall the parent software from the developer's official site instead of replacing this component by itself.
What is d3d11.dll?
Evidence-based answer
d3d11.dll is a Windows library or loadable module, about 1.4 MB. We identify a file by its cryptographic hash rather than its name, because the same filename can be reused by completely different files — the hash below is the reliable fingerprint.
How many antivirus engines detected d3d11.dll?
Evidence-based answer
4 of 75 antivirus engines flagged d3d11.dll, 4 of them as outright malicious. The raw count alone does not establish safety or danger; we also weigh which engines flagged it and corroborating behavior, identity, reputation, and rule evidence.
What should I do if I already used d3d11.dll?
Evidence-based answer
Act quickly. 1) Disconnect the device from the internet to stop the malware communicating or spreading. 2) Run a full scan with reputable anti-malware software (such as Malwarebytes) and quarantine everything it finds. 3) Change your important passwords from a DIFFERENT, clean device — many threats log keystrokes or steal saved credentials. 4) If you bank or shop on this device, watch closely for fraud and alert your bank. 5) For a confirmed infection, the most reliable fix is to back up your personal files and reinstall the operating system for a clean start.
How do I remove d3d11.dll?
Evidence-based answer
To remove d3d11.dll: 1) restart into Safe Mode (Safe Mode with Networking if you need to download a tool) so the malware doesn't auto-start. 2) Run a full scan with reputable anti-malware software and let it quarantine or delete the detections. 3) Quarantine this component with your antivirus, then repair or reinstall the parent software from its official source. Do not delete or replace the component manually. 4) Check your browser extensions, startup items, and scheduled tasks for anything unfamiliar. 5) Reboot and scan again to confirm it's gone. If detections keep coming back, a clean operating-system reinstall is the most dependable cure.
What kind of malware is d3d11.dll?
Evidence-based answer
d3d11.dll is classified as a hacktool — dual-use offensive tooling that is dangerous regardless of intent. Engines attribute it to the gamehack family. Knowing the family matters because it tells you the likely impact — data theft, remote control, file encryption, or unwanted ads — and guides the cleanup.
What is the SHA-256 hash of d3d11.dll?
Evidence-based answer
The SHA-256 hash of d3d11.dll is b5bcbd7f2df1c2b04d90ba25040539dbb2062c7c673fd38cf48bb1dd3ca26343, and its MD5 is 4c3adbe7b800d422053e4e55f76b6072. This hash is the file's unique fingerprint — two files with the same SHA-256 are identical. Use it to confirm you're looking at exactly this file (not just one with the same name) when comparing against antivirus databases or a download's published checksum.
How up to date is this analysis of d3d11.dll?
Evidence-based answer
This report reflects the scan run on August 16, 2026. Because a file's hash never changes, the identity of d3d11.dll is fixed — but antivirus coverage improves over time, so a file that looks clean today can pick up detections later (and vice-versa). If you need the latest picture, MalwareTips staff can re-run the analysis from scratch.
