Is pcre2-8.dll safe?
No antivirus engine detected this widely seen, verified CD PROJEKT DLL, while isolated behavioral mappings lack corroborating sandbox, network, or child-file evidence.
The DLL drew no detections from 74 antivirus engines, including 17 tier-1 engines, and carries a verified CD PROJEKT S.A. signature. Although one sandbox mapped activity to process injection and defense impairment techniques, it issued no malicious verdict, observed no persistence or network contacts, and found no confirmed malicious child.

Before using
Use it only as part of software obtained from the developer's official site or another source you independently trust.
If you already used it
Keep normal device protection enabled and stop if the file behaves unexpectedly.

The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
The DLL drew no detections from 74 antivirus engines, including 17 tier-1 engines, and carries a verified CD PROJEKT S.A. signature. Although one sandbox mapped activity to process injection and defense impairment techniques, it issued no malicious verdict, observed no persistence or network contacts, and found no confirmed malicious child.
All 74 antivirus engines returned no malicious or suspicious detection, with all 17 participating tier-1 engines silent. The DLL is verified as signed by CD PROJEKT S.A., has no detected brand conflict, and has appeared in 350 submissions from 315 sources. Two prior files matched by signer also received clean assessments, strengthening the publisher context. A completed sandbox run mapped T1055 and T1562.001, but produced no malicious verdict, persistence indicator, or network contact. Those behavioral mappings warrant context-sensitive caution but are not corroborated by engines, external intelligence, packing indicators, or confirmed malicious children. A complete contacted-host reputation result is unavailable because contactedHosts was not saved.
What We Detected
No malicious or suspicious result appeared among 74 antivirus engines, and all 17 tier-1 engines reported no detection. The DLL has a verified signature from CD PROJEKT S.A., no detected brand mismatch, and established prevalence across 315 sources and 350 submissions. Two previous files sharing this verified signer also received clean assessments.
Threat Behavior
One completed sandbox run mapped activity to T1055 (Process Injection) and T1562.001 (Impair Defenses). These mappings are concerning in isolation, but the run produced no malicious sandbox verdict, persistence indicators, or network contacts. None of the 10 inspected child hashes was confirmed malicious, although all remain unclassified. No complete host-reputation cross-check is available because contactedHosts was not saved.
What To Do Now
Keep endpoint protection enabled and obtain the DLL through the official game installation or update channel. If its signature no longer verifies, its hash differs after an unexpected replacement, or it appears outside the expected application directory, quarantine that copy and rescan the installation.
Where this verdict could be wrong4 caveats
- triggeredHeuristics[0].rule='MalwareTips.Synth.ProcessInjection' maps sandbox activity to T1055, but the mapping does not establish a specific injection method or malicious intent.
- T1562.001 was also mapped during the single sandbox run, creating a behavioral concern despite the absence of a malicious sandbox verdict.
- droppedChildren.inspected=10, but all 10 child verdicts are unknown; hasMaliciousChild=false therefore provides limited reassurance.
- contactedHosts=null, so no complete host-reputation cross-check is 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.
- 0/74 engines reported a detection
- 17 tier-1 engines reported no detection
- Verified signature from CD PROJEKT S.A.
- 315 sources and 350 submissions over 431 days
- Two prior clean signer-matched files
- Sandbox mapping to T1055 process injection
- Sandbox mapping to T1562.001 defense impairment
- Ten inspected child hashes remain unclassified
- No saved contacted-host reputation cross-check
Keep protection enabled and use the DLL only as part of an official, correctly signed CD PROJEKT installation. Reinstall or verify game files if this copy appeared unexpectedly or outside its normal application directory.

The available sources did not agree on a named threat category.
MalwareBazaar, YARAify, and CIRCL hashlookup completed and returned no entries for this hash.
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.

Section entropy & packers
No high-entropy executable section or known packer signature was detected. Data and resource sections can still have high entropy without indicating packed code.
How widely this file has been seen
Widely seen in the wild for a long time. High prior this is legitimate; isolated detections on common-old files are usually false positives.
