Is apisetstub safe?

Verdict
Safe

No engine detected this established, validly signed CD PROJEKT DLL, and both observed execution and five signer-matched historical files provide no threat corroboration.

The DLL has a valid CD PROJEKT S.A. signature, and none of 74 antivirus engines flagged it. It is well established across 139 sources, while one completed sandbox found no malware-exclusive techniques or malicious conclusion; five prior signer-matched files also had clean assessments.

Open with normal care

Retain the file if it came from an official CD PROJEKT installation or update and the signature remains valid. Keep endpoint protection enabled and quarantine it for review if the signature or installation context changes.

The reasoning behind this verdict

This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.

98%Confidence

Analyst conclusion

The DLL has a valid CD PROJEKT S.A. signature, and none of 74 antivirus engines flagged it. It is well established across 139 sources, while one completed sandbox found no malware-exclusive techniques or malicious conclusion; five prior signer-matched files also had clean assessments.

Where this verdict could be wrong3 caveats
  • signing.signerStats.totalSamples=1, so the direct historical signer-statistics record is still limited despite five consistent signer-matched prior verdicts.
  • contactedHosts=null, meaning no separately saved host-reputation cross-check is available; however, behaviour.contactedDomains, contactedIps, and contactedUrls are all empty.
  • The file carries a detect-debug-environment tag and invokes rundll32.exe, but no offensive technique, malicious sandbox conclusion, persistence indicator, or dropped child corroborates abuse.

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

Retain the file if it came from an official CD PROJEKT installation or update and the signature remains valid. Keep endpoint protection enabled and quarantine it for review if the signature or installation context changes.

What to do now

This file appears low risk based on the evidence available now.

  1. Recovery step 01

    Open it only when its sender or download source is one you independently trust.

  2. Recovery step 02

    A clean result reduces known risk, but it cannot guarantee that every new or targeted threat has been detected.

  3. Recovery step 03

    Keep your antivirus and Windows updates switched on so you stay protected.

7 evidence-based answers
Is apisetstub safe?
Evidence-based answer
apisetstub appears safe. 0 of 74 antivirus engines flagged it. It carries a verified digital signature from CD PROJEKT S.A.. Open it only when its sender or download source is one you independently trust.
What is apisetstub?
Evidence-based answer
apisetstub is a file, about 17 KB. Our analysis did not identify a verdict-driving threat signal. It carries a verified digital signature from CD PROJEKT S.A.. A file's name can be reused by different files, so we identify it by its cryptographic hash (below).
How many antivirus engines detected apisetstub?
Evidence-based answer
None — 0 of 74 antivirus engines flagged apisetstub. That's reassuring, though it is not proof that a file is safe, so we also weigh its behaviour, identity, and reputation.
Is apisetstub digitally signed?
Evidence-based answer
Yes — apisetstub carries a valid digital signature from CD PROJEKT S.A., which confirms the file hasn't been tampered with since that publisher signed it. A valid signature is a positive signal, but note that malware is occasionally signed with stolen or abused certificates, so it isn't proof of safety on its own.
What is the SHA-256 hash of apisetstub?
Evidence-based answer
The SHA-256 hash of apisetstub is 441fef8b3a203766c2ffcdf1aa0984c6cd66e6d8f6eb142cf9c4e0b1090b2b54, and its MD5 is 65726623f5a2d71c60dfd3fae4667868. 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.
Is it safe to open apisetstub?
Evidence-based answer
Based on the recorded evidence, apisetstub has a low observed risk and is properly signed. The important caveat is source: make sure you downloaded it from the official website or a trusted store, because attackers sometimes distribute malware-laced copies under a legitimate file's name. If your own antivirus flags it, verify the source and the exact hash before overriding the warning.
How up to date is this analysis of apisetstub?
Evidence-based answer
This report reflects the scan run on September 23, 2026. Because a file's hash never changes, the identity of apisetstub 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.
