Is ffx_frameinterpolation_x64.dll safe?
No engine detections, a verified CD PROJEKT signature, and five matching publisher precedents outweigh uncorroborated runtime heuristics involving injection and direct-IP traffic.
All 74 malware engines returned no detection, including 17 tier-1 engines, and the DLL carries a verified CD PROJEKT S.A. signature. Runtime evidence includes process-injection and defense-evasion mappings plus two direct-IP contacts, but no sandbox malware verdict, malicious child, or corroborating intelligence supports those heuristic concerns.

The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
All 74 malware engines returned no detection, including 17 tier-1 engines, and the DLL carries a verified CD PROJEKT S.A. signature. Runtime evidence includes process-injection and defense-evasion mappings plus two direct-IP contacts, but no sandbox malware verdict, malicious child, or corroborating intelligence supports those heuristic concerns.
The DLL received no malicious or suspicious detection from 74 engines, with all 17 reporting tier-1 engines returning no detection. Its signature verifies to CD PROJEKT S.A., no conflicting brand was identified, and five prior files matched by that signer received clean historical outcomes. One completed sandbox mapped activity to T1055 and T1562.001, but it did not issue a malicious verdict or record persistence. Ten written child hashes were inspected without a malicious child finding, although their individual classifications remain unresolved. Two direct IP addresses were contacted, and no complete host-reputation result is available because that cross-check was not saved. Taken together, the authenticated publisher, broad engine agreement, and consistent signer history substantially outweigh the isolated behavioral heuristics.
What We Detected
The DLL was not flagged by any of 74 malware engines, including 17 tier-1 engines. It is signed with a verified certificate issued to CD PROJEKT S.A., and no publisher-brand conflict was detected. Five historical samples matched by this signer also received clean outcomes, including another FFX-related DLL.
Threat Behavior
One sandbox run mapped activity to T1055 and T1562.001 and observed direct connections to 135.233.45.221 and 172.178.240.161. These are relevant caution signals, but the sandbox issued no malicious verdict and recorded no persistence. Ten child hashes were inspected without a malicious-child result, though their individual classifications remain unknown. No complete reputation check is available for the contacted IP addresses.
What To Do Now
Use the DLL only as part of software obtained through CD PROJEKT's official installation or update channel, and verify that its digital signature remains valid. Keep endpoint protection enabled and investigate further if the file appeared outside an expected game directory or arrived from an unofficial source.
Where this verdict could be wrong3 caveats
- The runtime mapping includes T1055 and T1562.001, which can indicate process injection and impairment of defenses, although the completed sandbox produced no malicious verdict.
- The sample contacted 135.233.45.221 and 172.178.240.161 directly; contactedHosts=null means their reputation was not fully cross-checked.
- All 10 inspected dropped-child hashes have unknown individual verdicts, despite droppedChildren.hasMaliciousChild=false.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- 0/74 engines reported a malicious or suspicious result.
- All 17 reporting tier-1 engines returned no detection.
- The digital signature verifies to CD PROJEKT S.A.
- Five of five similar signer-matched files have prior clean outcomes.
- No malicious sandbox verdict, persistence indicator, or malicious child was recorded.
- Runtime evidence mapped activity to T1055 process injection.
- Runtime evidence mapped activity to T1562.001 impairment of defenses.
- Direct connections were observed to two IP addresses without a completed reputation cross-check.
- All ten written child hashes remain individually unclassified.
Accept the file when it comes from an official CD PROJEKT installation and its signature validates. Keep security protection enabled and quarantine it for further review if its source or installation path is unexpected.

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.
Evidence"C:\Windows\sysnative\rundll32.exe" "C:\Users\<USER>\Desktop\ffx_frameinterpolation_x64.dll",#1The 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.
